Reinrassige Motorsporttechnik, faszinierendes Rennwagen-Design

Automobile Faszination gepaart mit spektakulärem Rennwagen-Design – das ist der neue Mercedes-Benz SLS AMG GT3. Die Rennversion des Flügeltürers wurde als Kundensport-Fahrzeug für die Teilnahme an Rennserien nach dem seriennahen FIA GT3-Reglement konzipiert. Für kompromisslose Fahrdynamik sorgen konsequenter Leichtbau sowie Optimierungen an Fahrwerk, Brems-anlage und Aerodynamik.

Das puristische Design des SLS AMG mit langer Motorhaube, flachem, weit hinten positioniertem Greenhouse und kurzem Heck erfährt mit der GT3-Variante eine weitere Steigerung. Durch die Modifikationen an der Karosserie wirkt der Flügeltürer noch spektakulärer. Das Ziel: eine weitere Steigerung der aerodynamischen Performance.

Von vorn zeigt der GT3-Rennwagen eine neue Frontschürze mit größeren Lufteinlässen. Die breite Öffnung unterhalb des charakteristischen Kühlergrills mit dem großen Mercedes-Stern und der flügelförmigen Querfinne versorgt den Motorölkühler und die Bremsscheiben mit Kühlluft. Die gleiche Funktion haben die beiden Einlässe unterhalb der vertikal ausgerichteten Bi-Xenon-Scheinwerfer. Für Abtrieb an der Vorderachse sorgt neben den vier außen angebrachten, so genannten Flics auch der Carbon-Frontsplitter: Er geht direkt in die glatte Unterbodenverkleidung über, an die sich der Heckdiffusor anschließt.

Die Motorhaube verfügt über eine zentrale Öffnung zum Abtransport der Motorwärme. Aus den seitlichen Öffnungen in den vorderen Kotflügeln entweicht die Luft aus den Radhäusern. Zur Gewichtsoptimierung kommen rundum besonders leichte Polycarbonatscheiben zum Einsatz.

Vorn wie hinten wurden die Kotflügel verbreitert, um Platz für die großen Rennreifen zu machen. Mit einer Breite von 1990 Millimetern ist die GT3-Karosserie um gut 50 Millimeter breiter als die des serienmäßigen SLS AMG. Die neuen Seitenschweller verfügen über Öffnungen zur Kühlung der hinteren Brems-anlage. Am unteren Ende der Schweller ist der glatte Unterboden sichtbar. In der B-Säule findet der genormte Tankstutzen für die Schnelltankanlage Platz. Der 120 Liter große Kraftstofftank sitzt in zentraler Position hinter dem Fahrer.

Breiter Heckflügel aus Carbon

In der Heckansicht beeindruckt der SLS AMG GT3 durch seine imposante Breite. Über dem Heckdeckel thront ein breiter Heckflügel aus Carbon; er ist vielfach verstellbar und erlaubt ein perfektes Setup für den jeweiligen Rennstreckentyp. In der neuen Heckschürze sind zwei Öffnungen zur Entlüftung der hinteren Radhäuser angebracht. Ein weiterer Blickfang ist der Heckdiffusor aus Carbon: Als Verlängerung des glatten Unterbodens steigt er im Bereich der Hinterachse kontinuierlich an und sorgt durch seine Form für Abtrieb. Das aerodynamische Gesamtkonzept des SLS AMG GT3 wurde in ausgiebigen Windkanalversuchen sowie Rennstreckentests erprobt und festgelegt. Alle Maßnahmen sorgen für eine gute aerodynamische Effizienz – und garantieren auch eine effektive Kühlung der thermisch hoch belasteten Komponenten.

Im Heckdeckel integriert ist die vom Reglement vorgeschriebene Regenleuchte – sie muss vom Fahrer bei schlechter Witterung stets eingeschaltet werden.

Seriennaher AMG 6,3-Liter-V8-Motor

Wie vom FIA GT3-Reglement vorgeschrieben, entspricht der AMG 6,3-Liter-V8-Motor nahezu dem des Serienfahrzeugs. Dank seines geringeren Gewichts wird der GT3 die bereits hervorragenden Beschleunigungswerte des Serienfahrzeugs – 3,8 Sekunden für den Spurt von null auf 100 km/h – deutlich unterschreiten; die Höchstgeschwindigkeit beträgt je nach Übersetzung über 300 km/h. Typisch AMG: der faszinierende und gleichzeitig charakteristische Achtzylinder-Sound.
Die Höchstleistung des AMG 6,3-Liter-V8-Frontmittelmotors mit Trockensumpfschmierung wird von der FIA gemäß der „Balance of Performance“ bestimmt. Dies soll die Chancengleichheit der teilnehmenden Rennfahrzeuge gewährleisten. Die Einstufung, bei der unter anderem auch das Leergewicht des Fahrzeugs festgelegt wird, erfolgt im Frühjahr 2011.

Der AMG 6,3-Liter-V8-Motor verfügt auch im Rennfahrzeug über Trockensumpfschmierung. Der Einsatz von Saug- und Druckpumpe sowie eines externen Öltanks ermöglicht den Verzicht auf die sonst übliche Ölwanne. Diese Technik gewährleistet eine zuverlässige Schmierung des Motors selbst bei hohen Quer-beschleunigungen, wie auf Rennstrecken üblich. Die Trockensumpfschmierung erlaubt zudem eine tiefe Einbaulage des V8-Triebwerks – eines der wichtigen technologischen Highlights des SLS AMG. Die Lösung, den Achtzylinder möglichst tief und als Frontmittelmotor hinter der Vorderachse zu installieren und mit einem an der Hinterachse platzierten Getriebe zu kombinieren, führt zu einem günstigen Gewichtsverhältnis. Die Transaxle-Anordnung optimiert zudem Handling und Traktion.

Sechsgang-Renngetriebe mit sequenzieller Schaltung

Im Gegensatz zur Serie ist im SLS AMG GT3 ein Sechsgang-Renngetriebe mit sequenzieller Schaltung für die Kraftübertragung verantwortlich. Dank seiner kompakten Bauweise bietet das rennsporterprobte Getriebe Vorteile beim Packaging – schließlich hat die GT3-Version eine geringere Bodenfreiheit als das Serienfahrzeug. Der Pilot schaltet die Gänge mithilfe zweier Schaltpaddles am Lenkrad. Das Getriebe ist direkt an der Hinterachse montiert und mittels einer Torque Tube biege- und drehmomentsteif mit dem V8-Motor verbunden. Damit sind entscheidende Vorteile in puncto Fahrdynamik verbunden, denn diese aufwendige Lösung erlaubt es, den kompletten Antriebsstrang deutlich spielfreier auszulegen. Ein im Getriebe integriertes Lamellen-Sperrdifferenzial sorgt in Verbindung mit der Traktionskontrolle für ein ausgezeichnetes Beschleunigungsvermögen. Im Innern der Torque Tube rotiert eine Antriebswelle mit Motordrehzahl. Wie beim Serienmodell und bei den Mercedes-Benz C-Klasse DTM-Renntourenwagen besteht die Welle aus Carbon (CFK).

Doppelquerlenkerachsen aus geschmiedetem Aluminium

Geradezu für die Rennstrecke prädestiniert ist das Fahrzeugkonzept des SLS AMG mit langem Radstand, tiefem Schwerpunkt und breiter Spur. Zu den Stärken zählen präzises Einlenkverhalten, erstklassige Agilität, geringe Massenträgheit bei spontanen Richtungswechseln und hoher Kurvengrenzbereich.

Für eine perfekte Rennstrecken-Performance musste am Fahrwerk nur wenig geändert werden: Das leichte Aluminium-Fahrwerk mit doppelten Dreiecksquerlenkern rundum verfügt aufgrund der abgesenkten Fahrzeughöhe über eine angepasste Kinematik. Eine optimale Anpassung an den jeweiligen Rennstrecken-charakter und an unterschiedliche Witterungsbedingungen erlauben die viel-fältigen Einstellmöglichkeiten. So kann nicht nur zwischen unterschiedlichen Feder- und Dämpfersetups gewählt werden, auch die Justierung von Spur und Sturz, die Einstellung der Fahrzeughöhe und der Stabilisatoren an Vorder- und Hinterachse ist möglich.

Stahl-Rennsportbremsanlage mit Renn-ABS

Die Zahnstangenlenkung mit direkterer Übersetzung und Servounterstützung unterstützt das agile Handling. Hinter den 18 Zoll AMG Leichtmetallrädern mit Zentralverschluss übernimmt eine Stahl-Rennsportbremsanlage eine effektive und standfeste Verzögerung. Der SLS AMG GT3 verfügt über exakt berechnete Kühlkanäle: Öffnungen in der Frontschürze und vor den Hinterrädern versorgen die Bremsscheiben mit kühlem Fahrtwind. Alle vier Bremsscheiben sind belüftet, genutet und gelocht. Sechskolben-Festsättel an der Vorderachse und Vierkolben-Festsättel hinten erlauben üppige Bremsbelagflächen. Ein Antiblockiersystem mit spezieller Rennstrecken-Abstimmung ist serienmäßig.

Auf AMG Leichtmetallrädern mit Zentralverschluss im Format 12 x 18 Zoll (vorn) und 13 x 18 Zoll (hinten) sind Rennreifen montiert. Je nach Einsatzzweck kommen profillose Slicks oder Regenreifen zum Einsatz. Das klassische Vielspeichendesign begünstigt die Belüftung der Bremsanlage. Schnelle Boxenstopps und Räderwechsel garantiert die im Unterboden integrierte Luftheberanlage: Vier pneumatische Stempel heben den GT3-Rennwagen um rund 190 Millimeter an und ermöglichen der Boxencrew einen schnellen Wechsel der Rennreifen.

Funktionelle Rennwagen-Atmosphäre, vorbildliches Sicherheitsniveau

Im Interieur des SLS AMG GT3 dominiert funktionelle Rennwagen-Atmosphäre: Wie beim Serien-Flügeltürer sorgt auch im Rennfahrzeug die Instrumententafel in Form eines kraftvollen Flügelprofils für optische Breite. Markant in die Instrumententafel integriert sind die in „Silver Shadow“ galvanisierten Belüftungsdüsen mit justierbarem Düsenkreuz – ihre Form erinnert an die Triebwerke eines Jets.

Ähnlich wie in den DTM-Fahrzeugen von Mercedes-Benz befindet sich die Sitzschale in einer Sicherheitszelle aus hochfestem Carbon (CFK). Durch ihre spezielle Form bietet die mit dem Überrollkäfig und dem Aluminium-Spaceframe verschraubte Sicherheitszelle einen deutlich verbesserten Schutz für Schultern, Hüfte und Beine des Fahrers; zudem ist sie kompatibel mit dem HANS-System (Head and Neck Support). Die Sitzschale wird individuell geschäumt, verfügt über einen Sechspunktgurt und ermöglicht damit höchste Insassensicherheit. Für zusätzliche Sicherheit sorgt der Überrollkäfig aus Stahl, der zudem den Aluminium-Spaceframe weiter versteift. In Verbindung mit dem auf der Hinterachse positionierten, 120 Liter großen CFK-Sicherheitstank mit Innenblase sowie der optimierten Feuerlöschanlage bietet der SLS AMG GT3 ein vorbildliches Sicherheitsniveau, das derzeit von keinem aktuellen GT3-Fahrzeug erreicht wird.

Optimal im Blickfeld des Fahrers ist das Zentral-Display positioniert, das über alle relevanten Informationen wie Geschwindigkeit, Motordrehzahl, Betriebs-Temperaturen, Rundenzeiten und die Gangwahl informiert. Das Rennlenkrad mit Schaltpaddles für den Gangwechsel ermöglicht perfekte Fahrzeugkontrolle; der Schnellverschluss erleichtert Ein- und Ausstieg deutlich. Über die Schalter auf dem Lenkradpralltopf kann der Fahrer zusätzliche Funktionen wie den Boxenfunk, die Lichthupe oder die Trinkfunktion aktivieren. Auf der Mittelkonsole befinden sich zusätzliche Bedienelemente. Hier kann der Fahrer nicht nur den AMG V8-Motor starten oder die Traktionskontrolle justieren, sondern auch den Rückwärtsgang oder – für den Fall der Fälle – die integrierte Feuerlöschanlage aktivieren. Eine Einstellmöglichkeit für die Bremsbalance ist ebenso vorhanden.

Testprogramm mit Bernd Schneider im Juni 2010 gestartet

Die Entwicklung des neuen Mercedes-Benz SLS AMG GT3 verläuft planmäßig; das Testprogramm wurde im Juni 2010 auf dem Eurospeedway Lausitz gestartet. Als Testfahrer sind der langjährige Mercedes-Benz Werksfahrer und AMG Markenbotschafter Bernd Schneider, 46, sowie Thomas Jäger, 33, im Einsatz. Bernd Schneider gilt mit fünf Titeln in der DTM sowie je einem in der ITC- und in der FIA GT-Meisterschaft als einer der erfolgreichsten deutschen Rennfahrer. Thomas Jäger ist amtierender Meister des Porsche Carrera Cup Deutschland und war von 2000 bis 2003 DTM-Fahrer für Mercedes-Benz. In der aktuellen Saison startet er in den ADAC GT-Masters (Deutschland).

Für Bernd Schneider, der den Hauptanteil der Testfahrten absolvieren wird, steht das Erarbeiten eines Basis-Setups im Vordergrund. „Der SLS AMG verfügt über hervorragende Gene, um im Motorsport erfolgreich zu sein. Bereits bei meinen ersten schnellen Runden auf dem Eurospeedway Lausitz war zu spüren, dass die GT3-Version des Flügeltürers perfekte Voraussetzungen für die Rennstrecke mitbringt. Die Kombination aus optimaler Gewichtsverteilung, tiefem Schwerpunkt, kraftvollem AMG V8-Motor und effizienter Aerodynamik lässt den SLS AMG GT3 bereits heute sehr wettbewerbsfähig erscheinen.“

Erster Renneinsatz beim VLN-Lauf auf der Nürburgring-Nordschleife

Außer auf dem Eurospeedway Lausitz und dem Sachsenring wird der SLS AMG GT3 auch auf der Nürburgring-Nordschleife getestet – und dies bei realistischen Rennbedingungen. Neben reinen Test- und Abstimmungsfahrten geht der Flügeltürer auch im Rahmen der VLN-Langstreckenmeisterschaft 2010 ins Rennen.
Im Fokus des umfangreichen Entwicklungs- und Testprogramms stehen unterschiedliche Fahrwerkeinstellungen, Motor-Mappings, Reifenmischungen und Aerodynamik-Konfigurationen. Außerdem muss sich das Gesamtpaket hinsichtlich der Standfestigkeit und der Servicefreundlichkeit unter Beweis stellen. Parallel laufen der AMG 6,3-Liter-V8-Motor sowie das Sechsgang-Renngetriebe mit sequenzieller Schaltung auf den Prüfständen der HWA AG. Das Gesamtfahrzeug wird zusätzlich auf einem Fahrdynamik-Prüfstand getestet.

Service- und Ersatzeilversorgung für Teams gesichert

Mercedes-AMG und HWA werden den Teams auch bei Service- und Ersatzteil-fragen innerhalb Europas zur Seite stehen. Das Konzept für die europäische Motorsportsaison 2011 sieht vor, bei den drei bedeutendsten Meisterschaften und wichtigsten 24-Stunden-Rennen mit Teilnahme des SLS AMG GT3 eine umfassende Unterstützung anzubieten. Für alle weiteren Renntermine und Testfahrten steht ein 24-Stunden-Service für Ersatzteile und eine Technik-Hotline zur Verfügung.

Für interessierte Kunden bietet die AMG Driving Academy ein spezielles SLS AMG GT3-Fahrertraining an.

The 79th International Geneva Motor Show sees the introduction of the exciting new 2010 Model Year Lotus Exige S with a newly designed front end, a new rear wing and impressive emissions of just 199 g/km CO2.

The Lotus Exige is a renowned high performance coupe that has a well earned reputation of choice for drivers who demand uncompromised performance, both on the road and on the track.

Lotus has always pursued efficiency and fuel economy and for the 2010 Model Year Lotus Exige S, Lotus has reduced the emissions to only 199 g/km CO2 and increased the fuel economy to an impressive 8.5 litres/100 km on the Official European Combined Cycle and a frugal 6.5 litres/100 km on the Official European Extra Urban Cycle.

The 2010 Model Year also sees the introduction of a few key changes to the Exige to enhance the look and improve aerodynamic performance. A restyled front end and new larger, rear wing that not only reduces drag, but also gives a more muscular stance enhancing the lightweight shrink-wrapped look of the whole car.

The composite rear wing is based on the design from the Exige GT3 road car concept shown at the Geneva Motorshow in 2007. Compared to the 2009 Model Year Exige tailgate mounted wing it is 181 mm wider and mounted 46 mm higher and 61 mm further back. It is attached to the rear bodyshell clam via rear end plates which not only increases the stiffness of the whole structure but also ensures that as much of the airflow as possible passes over the rear wing. This careful airflow management increases stability, reduces drag and, most importantly, maintains the impressive downforce figures of 42 kg at 160 km/h.

The restyled front end includes a larger, more angular air intake mouth to help funnel more air through the radiator, to improve the efficiency of the engine system. Ahead of the front wheels on either side of the main aperture, two larger air intakes increase the airflow to the twin oil coolers. Horizontal vanes bisect these oil cooler air-intakes to stabilise the airflow to further increase the cooling efficiency.

Since the Exige S2 was launched in 2004, the power has increased from 190 hp through 220 hp to 240 hp in standard road form – more for the track centric Exige Cup 260 – and the new larger air intakes improve engine cooling for these current higher powered Exige variants.

Mounted below the three new air intakes is a new aerodynamic splitter for the 2010 Model Year Exige. Made from a lightweight composite, the splitter is now extended to wrap around the whole of the front end and chiseled side lips are raised to deflect air around the tyres to reduce drag.

Mike Kimberley, Chief Executive of Group Lotus plc said, “Over the years, the Lotus Exige has developed a hardcore fan base around the world and its popularity has placed it as one of the legendary sportscars of the 21st century. So far, over 5000 Exiges have been hand-built at our high-tech manufacturing facility making it a significant contributor to our global production. The lightweight Exige has one of the highest specific power outputs of any globally emissions certified car and 133 hp per litre is a perfect demonstration of Colin Chapman’s philosophy of performance through light weight and of Lotus’ relentless pursuit of efficiency. The same technology that makes a lightweight car a high performer also makes it efficient – how many cars have performance figures of 0 – 100 km/h in 4.77 secs but produce only 199 g/km CO2?”

Like all Lotus cars, the functional components of the car are also beautifully designed as Russell Carr, Chief of Lotus Design, explains, “For 2010 we have taken the already visually extreme Exige and given it even more visual drama. The changes we have integrated into the front and rear of the Exige signal an even clearer and purposeful intent. The purposeful rear wing is race inspired, the new angular air intakes and full width splitter gives a more hard-edged and aggressive look. Overall, the Exige appears more planted and gives the illusion that both the front and rear of the car are wider than they really are without losing its agile and lithe character.”

Roger Becker, Director of Vehicle Engineering said, “The changes we have made to the Exige for 2010 Model Year are quite subtle when taken individually, but taken as a complete package they make significant improvements to aerodynamics and the overall look of the car. The Exige is a classic fit-for-purpose performance machine, the design tweaks we have made have reduced the drag, cleaned up the airflow around the front and rear of the car, whilst retaining the impressive balanced downforce figures, to give an exciting high performance drive.”

The specification of the highly successful 2009 Model Year Exige Cup 260, unveiled at the Paris Motorshow in 2008 remains unchanged. The 2010 Exige in more detail: Driver and passenger airbags are standard on all models while an on-board Tyre Pressure Monitoring System is standard in the USA. The instrument pack in the Exige contains much more than just a pair of stylishly back-lit dials. It also features a high-definition LCD message panel that can display a scrolling text message with vehicle systems information. The instrument pack always displays the fuel gauge, engine temperature and odometer, however you can select to display the time, trip distance or a digital read-out of your speed in the opposite calibration to that of your speedometer dial – if your dial is in mph, the readout is in km/h.

Warning symbols are ‘secret until lit’, keeping the instrumentation free from visual clutter and distraction until necessary. Gearchange ‘shift’ lights similarly remain hidden until required. There are three shift up warning lights, cumulatively lighting when the driver is getting closer to the rev limiter and when all three are illuminated, they flash to indicate that you should have changed up a gear by now!

A “key” issue

The Exige has a “Thatcham approved” alarm/immobiliser system and the ignition key incorporates the controls for the alarm/immobiliser and central locking functions. This key features three buttons, the one which locks the doors and sets the alarm/immobiliser is stylishly crowned with the famous Lotus roundel. The second button unlocks the doors and de-actives the alarm/immobiliser, and the final button is a panic alarm button.

The contents of the Touring pack, for the Exige S includes:

• Full leather or Microfibre suede-effect interior
• Leather trimmed centre console
• Leather handbrake gaiter
• Sound system iPod* connection
• Full carpets, with embroidered logo
• Auxiliary driving lights (in markets where legally allowed)
• Sound insulation kit
• Cup holder

The Exige S Sport pack includes:

• Bilstein sports dampers
• Traction control
• Adjustable front anti-roll bar
• T45 roll bar, with integrated harness mounts

The Exige S Performance Pack – more punch, more ability for Exige S

• 308 mm front cross-drilled and vented discs with AP Racing four piston callipers
• Uprated front and rear brake pads
• Full length upsized roof scoop
• Variable slip traction control
• Uprated clutch plate and cover
• Uprated vehicle performance through enhanced power and torque delivery
• Launch control

With the Exige performance pack, the power is raised to 240 PS / 179 kW (minimum) at 8000 rpm courtesy of a Magnuson/Eaton M62 supercharger, new faster flowing injectors and higher torque clutch system and an upsized roof scoop to feed more air to the supercharger intercooler system. This hike in power, together with an increase in torque to 170 lbft / 230 Nm / 23.5 kgm at 5,500 rpm from the standard 158.6 lbft / 215 Nm / 22 kgm at 5500 rpm, helps whisk the Performance Pack Exige S from zero to 60mph in 4.5 secs and 0-100km/h in 4.77 secs, and on to 100mph in 11.97 secs. Top speed rises to 145 mph. The power and torque of the 240 PS engine is increased across the rev range giving even more flexibility. Despite these high levels of performance the fuel economy is impressive with a new combined figure of 8.5 litres / 100 km and 199 g/km CO2 – reduced from 9.1 litres / 100 km (combined) and 216 g/km CO2 for the 2009 Model Year Exige. Continuous engineering improvements over the last year including careful whole vehicle optimisation has enabled this sportscar to be even better for fuel economy and emissions.

Of course the increased power and straight-line performance are only a couple of elements of the Performance Pack option. The clutch is uprated and a clutch damper fitted; there are thicker, 308mm diameter cross-drilled and vented discs at the front clamped by AP Racing four-piston callipers; the standard brake pads are replaced by uprated pads. Keen to pass on lessons learned on the track with the Exige GT3 racing programme, Lotus Sport has contributed another important track specific technology to the Performance Pack – launch control combined with variable traction control.

From the driver’s seat the track orientated launch control allows you to determine the engine revs you wish to use during a standing start on the track. Having programmed that limit, it will not be exceeded when you then hold down the throttle and sidestep the clutch at departure from the line. The clutch damper cushions the severity of the clutch / transmission engagement to minimise the stresses to the drivetrain (noting that continuous abusive standing start applications will destroy the drivetrain components). The launch control also keeps wheelspin at bay until 6 mph, after which the traction control assumes its duties.

As with launch control, you can dial in the amount of traction control you require from the driver’s seats, altering it on the move to suit driving style and the characteristics of particular corners. The amount of traction control can be varied in over 30 increments from an optimum 7 percent tyre slip to completely off. The message display in the new instrument pack displays what degree of traction control you have currently dialled in. The beauty of all the packs is that they can be combined so a customer can have the additional interior and exterior equipment from the Touring pack with the sport focussed equipment from the Sport pack. Air conditioning, Lotus traction control and limited slip differential are available as stand-alone options.

Customers wanting to add further finishing touches to their Exige – such as specifying adjustable dampers and forged wheels can do so by ordering from an extensive range of accessories.

Colours

The Premium Colour Range has been designed to further enhance the choice for customers to individualise their cars. Most of the paints in this range require a more sophisticated application process and are from our paint supplier’s premium range. The paint colours in this range have been individually priced, and it is Lotus’ intention to extend and change this range at periodic intervals.

The 2010 Model Year Exige S will enter the EU markets in May 2009.
Exige S: 199 g/km CO2
8.5 litres/100 km (33.2 mpg) Combined Cycle
11.9 litres/100 km (23.7 mpg) Urban Cycle
6.5 litres/100 km (43.5 mpg) Extra Urban Cycle

With class leading driving dynamics, fuel economy and emissions of just 205 g/km of CO2, the new Lotus Evora raises the bar for world class high performing sportscars.

The first all-new Lotus since the iconic Elise roadster made its debut in 1995, the Evora enters the sports car market as the world’s only production mid- engined 2+2. The Evora provides a tremendously rewarding driving experience: the mid-engined layout gives exceptional agility and the Lotus engineered suspension ensures incredible ride and handling. Powered by a Lotus-tuned 3.5-litre V6 engine producing 280 PS, and weighing just 1350 kg (prototype specification)*, the Evora delivers an exhilarating experience true to the Lotus DNA characteristics.

With the zero to 100 km/h sprint taking place in just over 5 seconds, a top speed of over 260 km/h (prototype specification)* and an Official European Combined Cycle fuel economy just 8.7 litres / 100 km and emissions of just 205 g/km CO2 the Evora stays true to the ethos of performance through light weight. The other economy figures are equally impressive with Official European Urban Cycle of 12.4 litres / 100 km and 6.5 litres / 100 km for the Official European Extra Urban Cycle all combined with exceptional ride and handling.

Because one of the roles of the Evora is to attract new lifestyle customers, as well as performance aficionado’s to the Lotus brand, the Evora offers a more refined ownership experience than Lotus’ existing smaller four cylinder models. Its elegantly styled cabin is beautifully trimmed and its equipment list includes contemporary features such as an advanced touchscreen multi-media system and electric power-fold door mirrors. Careful attention has also been paid to its ease of use. with wider, taller door apertures, narrower sills and higher seating position making getting in and out of the cabin a less athletic undertaking than it is in Lotus’ smaller sports cars (Elise, Exige, Europa and 2-Eleven), whilst the design of the cabin itself will accommodate two 99th percentile (6ft 5in tall) American males in the front seats.

The ‘convenience factor’ of the Evora extends to all areas of the car. For instance, beneath the skin the entire front-end structure is a high tech aluminium “sacrificial” modular unit, with bolt on attachment to the main extruded aluminium tub. This modular unit is not only designed to deform for maximum safety, and to make the production assembly process more efficient, but also to reduce repair costs in the event of a frontal impact.

The Evora has been designed with global automotive regulations in mind, and future derivatives are planned, these including amongst others, a convertible at a later stage of the six year lifecycle span.

The Evora will be hand crafted and built on a dedicated new assembly line within Lotus’ advanced manufacturing facility at Hethel in the East of England; capacity limitations will restrict production to less than 2000 cars a year, thus ensuring this dynamic new sports car’s rarity and exclusivity.

Mike Kimberley, CEO of Group Lotus plc, has this to say about the exciting new model: “The Evora is the biggest “milestone” Lotus has achieved since the Elise was born 13 years ago and is the start of our bold five year strategic business plan. A plan which includes the introduction of three new cars and advanced new technologies to many more markets around the world. The Evora also represents Lotus core values of performance through light weight and efficiency, proving that you can have performance, fuel economy, elegant design and practicality all in a class leading mid-engine 2+2 sportscar, whilst also meeting all global safety and homologation standards” Mike Kimberley continues, “Looking to the future, we will continue to research, develop and produce lighter, more efficient vehicles which are linked to our extensive and well-regarded work on all aspects of future fuels, alternative engines and electric and hybrid vehicle propulsion system solutions. We all have an environmental responsibility to future generations and the Evora is another example where Lotus is seen to make significant steps towards improving the efficiency and sustainability of the motorcar, helping ‘UK Ltd’ to the forefront of high technology in the motor industry.”

THE EVORA IN DETAIL
Style or function? Have both…

Designed in-house by Lotus Design, the sleek and athletic form uses fluid forms and crisp surfaces to communicate velocity, agility and sophistication. Low and wide with modern cab forward proportions, muscular rear haunches and function optimised hip air intakes shows this is clearly a serious mid engined sportscar that skilfully hides the practicality of its two plus two accommodation.

Russell Carr, Head of Lotus Design, led the Evora’s design team with Steven Crijns, Design Manager responsible for the exterior and Anthony Bushell, Senior Designer, responsible for the interior.

“A cornerstone of the design’s success was working closely with the technical team and board to develop a package that allowed us to get the proportions correct,” says Head of Design Russell Carr, “The asymmetric wheel sizes, the short rear overhang, long front overhang and cab forward visor screen all contribute to giving the car visual movement and an agile stance. This is incredibly important to us because we want the car’s aesthetics to communicate its driving characteristics”

Lotus products have always embodied a perfect balance between form and function and the Evora successfully continues this heritage. “We never lost sight of the fact that, although this car must provide real world useability, sportscars are emotional purchases and that you have to seduce the customer through beguiling looks and exotic persona. We are, therefore, very proud that we have been able to use technical and user functionality to positively drive the design in key areas and create some of the car’s most distinctive features”, says Carr.

Ingress and egress, for example, dictated a minimal “step-over” to get into the Evora. We simply cut away the surface under the door and created a unique and dramatic piece of sculpture that enhances the stance of the car as well as its usability.

Elsewhere, aerodynamic considerations for drag, down force and cooling had significant but positive influence on the overall form and details such as air intakes. A desire to create balanced down force that increases cornering performance led to the adoption of the Lotus “signature” top exit radiator vent, race car inspired diffuser and “floating rear wing”. Drag limitation, drove the dramatic tear-dropped cabin layout and the curvaceous plan view has given the car a more muscular rear shoulder and conveys a level of sophistication appropriate to this market segment. “We believe that our designs should be honest as well as dramatic and so we are really pleased with the fact that these iconic features all do a real job” says Steven Crijns, Design Manager.

This inherent understanding of the relationship between the technical and the aesthetic paid dividends the first time a full-scale model of the Evora was windtunnel tested – only minimal adjustments were required to the car’s aerodynamic package to meet the targets for downforce and stability.

Steve Crijns continued, “Overall the design language shows a clear DNA link with its Lotus siblings, whilst establishing its own distinctive and contemporary theme. The undulating shoulder line is brilliantly mirrored in the lower part of the bodyside by the cut -away sill that creates a torseau-like muscularity.”

“The front three-quarter view is really powerful” Russell Carr continues, “Your eye is drawn effortlessly, from our signature oval mouth, rearward by fluid surfaces and fast lines that create a sense of speed even when the car is stationary. From this angle you can also see how dramatically the visor screen sweeps around the teardrop form of the cabin and the gently waisted plan shape perfectly accentuates the muscularity of the rear fender. This is unmistakeably mid engined language and the Evora is unmistakeably Lotus.”

The view from the rear three-quarters is just as striking. The tapered cabin, diffuser, floating wing, centrally mounted twin tailpipes and distinctive engine bay vents all combine to create a completely unique look.

Moving right inside…

The design language of the interior reflects that of the exterior – simple, fluid surfaces, soft forms and crisp feature lines wrap around the cabin cosseting the occupants. Unlike recent Lotus products that use a race car inspired, technical minimalism, the Evora employs a softer approach that utilises premium quality materials and finishes to create a contemporary but luxurious ambience that is unique to Lotus products, an elegance in its simplest form.

It is, according to Russell Carr, “A huge departure from what people might expect based on Lotus’ recent past. The CEO wanted the Evora’s cabin to feel very special and to be surprising as well as sporty. Precision engineered metal inserts and quality edge-lit switches are brilliantly juxtaposed against soft hand-stitched leather surfaces to give a modern interior with a classic twist.”

Russell Carr continues, “The flat bottomed steering wheel, figure hugging sports seats, contemporary instrumentation and ergonomically positioned controls provide an intuitive environment that instantly forms a connection between driver and car ensuring that it becomes an extension of his or her body.“

Anthony Bushell, Senior Designer, explained about the choice of materials in the Evora’s interior, “’Tactile’ quality is incredibly important within this segment so in the Evora interior we use honest premium materials. Much of the switchgear is bespoke, and every metallic component is, actually, metal.”

For the Premium Pack focused courtesy lighting is used throughout the interior, giving a spectacular illuminated feel to the sculpture design features of the cabin. The extensive use of handcrafted, premium leather differentiates the Evora from other Lotus products and such is its importance to the character of the car that an entire new trim shop has been built at the Lotus Headquarters in the UK, dedicated to its production.

Even the entry level versions of the Evora will feature leather seats together with, upper door trim panels and facia upholstered in leather, but it is expected that most customers will opt for the full hide treatment and accent lighting available in the Premium Pack. Along with a range of four leather colours available in the Premium Pack, customers will have the opportunity to personalise their Evora with a wide range of paints in the Metallic, Lifestyle and Premium pallets.

High-tech treats

Contemporary technology also features in the Evora’s cabin with the optional Tech Pack and further standalone options. Part of the Tech Pack is a newly developed Alpine multi-media system with a 7 inch touch-screen providing advanced audio, satellite navigation, video, Bluetooth** hands-free telephone and iPod*** connectivity functions, the screen also serves as a monitor for the Evora’s optional reversing camera. A secondary handheld satellite navigation element of the system is removable, allowing you to programme it from the comfort of your home, or take it with you to continue your journey in an unfamiliar pedestrian location.

The optional IMPRINT Alpine audio set-up is one of the most sophisticated automotive systems in the world. Using MultEQ sound enhancement technology, it is able to cancel out sound imbalances, caused by the cabin window glass, that creates echoes or carpets that suppress mid-range frequencies, resulting in amazingly crisp, clear, undistorted sound reproduction wherever you are seated in the car.

A bespoke air-conditioning system developed by Lotus and Bergstrom engineers is standard on all models, and has been designed for the hottest climate or the closest humidity to ensure maximum occupant comfort. Lotus traction control is standard fitment and onboard tyre pressure monitoring will also be available (except in Japan).

One size fits all

The front seats themselves are very supportive and leather clad with a lightweight manual mechanism for fore and aft and rake angle adjustment, designed to give a supported driving position.

The rear seats of 2+2 versions of the Evora are intended for children and smaller adults. There will also be a two-seater derivative with a luggage shelf in the back at a later date. To maximise comfort in the rear, there’s a decent amount of footroom under the seats in front, while both back seats feature ISOFIX mountings for secure child seat fitment.

When unoccupied, the rear seats provide a convenient stowage area, adding to the Evora’s appeal as an everyday car. The 160 litre boot, which ingeniously features a fresh air cooling system to reduce the effect of any heat ingress from the engine bay, will also accommodate a full set of golf clubs.

Easy in, easy out

With the Elise and its derivatives, the no-compromise character of the car makes getting in and out across a wide sill and through a comparatively narrow door/window aperture part of the charm of ownership. For the Evora and its remit for the serious daily driver, and to attract newcomers to the Lotus brand, greater convenience and practicality of ingress and egress is provided.

As a consequence the sill is now lower and slimmer (80mm wide compared with 100mm in the Elise), and the whole door aperture taller. The doors open wider than on the Elise and its siblings, while the height of the front seat is raised by 65mm.

But while The Evora is undeniably more ‘lifestyle’ in respect of its everyday practicality, once you’re seated behind its semi flat-bottomed steering wheel, it feels every bit as exotic and sporting as you would expect a Lotus to be.

Safely does it

In common with the Elise and its derivatives, the Evora’s bonded extruded aluminium chassis tub has incredible inherent strength, particularly in regard to front and side impacts. Additional torsional strength is given to the whole structure by the tubular steel seatbelt anchorage frame.

Deformable sacrificial aluminium front and steel rear subframe modules are attached to the tub using joints which are designed to minimise damage to the tub, protecting the main passenger cell in the event of an accident.

Driver and passenger airbags are standard. The airbag on the passenger side is cleverly engineered to deploy vertically and then be deflected rearwards by the windscreen, to provide protection for children as well as adults.

Anti-lock brakes are standard on all models, as is Lotus Traction Control (LTC); these systems have been specially developed as a collaboration between Lotus and Bosch engineers and enable up and coming drivers to consistently exploit the braking and performance capabilities of the Evora, whilst allowing skilled enthusiasts the freedom to enjoy the full Lotus driving experience.

The chassis: Production Low Volume Versatile Vehicle Architecture

The Evora’s chassis is a low investment cost evolution of the Versatile Vehicle Architecture (VVA) from the Lotus APX concept vehicle previously showcased at the Geneva Motorshow, and allows for the development of a range of vehicles up to a gross vehicle weight of 1,900 kg. This architecture has been designed to be more applicable to mid-volume applications by utilising our low capital investment manufacturing processes. The Evora structure progresses the Lotus ‘bonded and riveted’ technology used in the Elise family of vehicles with new and unique extrusions and folded panels, whilst providing production build modularity and lower cost repairs.

The low volume VVA chassis has been designed for scalability so that it can be extended in width, length and height. The strength and stiffness of the low volume VVA chassis can be modified cost effectively by varying the wall thickness of the extrusions, without altering the exterior dimensions. The ability to lengthen or shorten extrusions with the option to tailor the chassis stiffness, vastly increases the number of vehicles that can be developed from this vehicle architecture. Front and mid engine installations have been considered, as well as hybrid and Electric Vehicle (EV) applications.

The Lotus Evora employs a composite roof as a stressed structural member to give an exceptional vehicle stiffness of 26,000 Nm per degree. This impressive stiffness is also thanks in part to the seatbelt anchorage frame, and partly because the high-tech composite body panels are stressed items. However, despite this high stiffness, the complete chassis or tub and front and rear modules weight just 200 kg (prototype specification)*, helping to keep the weight of the whole car to just 1350 kg (prototype specification)*.

To deliver this high performance structure, bonded and riveted high grade aluminium extrusions and simple and elegant folded sheet elements are used in the lower structure, building upon award winning Lotus research projects in this field. Lotus pioneered the technology of bonded aluminium extrusions for use in road vehicles and has successfully developed high performance cars for other car companies around the world using these techniques.

The central tub is attached to an extruded aluminium subframe at the front and a lightweight welded steel subframe at the rear. These subframe modules also offer advantages in terms of convenience and low cost of repair, and during manufacturing can be brought to the production line fully assembled, ready to be attached thereby improving the overall efficiency of space and time of assembly.

The high technology Lotus Evora chassis is manufactured at the new Lotus Lightweight Structures Limited (LLS) facility in Worcester, UK. LLS employs 120 skilled engineers, technicians and sales staff and will manufacture all the Lotus aluminium structures, including those for the Elise, Exige, 2–Eleven and Europa and aluminium components for Lotus’ extensive global client base.

Suspended & animated

To achieve exceptionally high driving dynamics and great levels of driver involvement, Lotus has engineered and developed completely new suspension systems for use on the Evora.

The Evora suspension wishbones are forged from aluminium to reduce the unsprung mass. These are similar in weight to the steel items found on the much smaller Elise, Exige and Europa vehicles, but are stiffer and have a much increased vehicle weight capacity. They are attached to the front and rear modules via Lotus designed bushes. The Evora will use Bilstein high performance dampers and Eibach springs with unique dual path top mounts for optimised vehicle refinement. Hydraulically assisted power steering is provided by a Lotus tuned TRW steering rack to give renowned Lotus steering feel and precision to place the Evora exactly where you want it to be when cornering.

All in all, the Evora delivers exceptional performance. It has incredible Lotus handling and provides unsurpassable driving pleasure and confidence to drivers at all levels of skill. In fact, word from the ride and handling team is that the new car is likely to become a class standard-setter in respect to it’s “over the road speed and agility feel”.

Stop right now…

Vented brake discs are standard with cross-drilled brake discs forming part of the Sport Pack, (both are massive 350mm diameter discs on the front and 332mm diameter at the rear), which when combined with high performance bespoke Lotus AP Racing 4 pot callipers ensure impressive stopping power.

Everyone connected with the brake testing programme, conducted on the punishing corners, climbs and descents of the Nürburgring and Stelvio Pass, has described the brakes as ‘phenomenal’ with excellent thermal performance and outstanding feel even after extended sessions of extreme use.

Part of that testing programme was to finalise settings for the ABS system being developed in conjunction with Bosch. The system is tuned for performance driving and thus has very high thresholds and operates so progressively that drivers are often unaware that they have actually triggered the ABS.

Hydraulic Brake Assist (HBA) and Electronic Brake Distribution (EBD) are also fitted as standard. HBA detects an emergency braking situation and increases brake pressure up to ABS activation threshold which results in shorter emergency stopping distances.

Safe. Fun. Lotus Traction Control

The Switchable Lotus Traction Control (LTC) system has been developed simultaneously with the ABS and works through the engine management system to reduce power to the rear wheels when required to maintain traction. To maintain front end traction or to reduce understeer, the LTC will gently reduce engine torque to stabilise the Evora bringing the front wheels back into line – known as “Understeer Recognition”. Unlike many traction control systems, LTC has been tuned to complement the skills of the driver without taking over. The Lotus LTC is active above 5 mph (8 km/h) and operates much more quickly than many brake based systems. The system can be deactivated completely, giving no traction control intervention.

A Bosch Electronic Differential Lock (EDL) is fitted as standard to the Lotus Evora. This advanced technology controls the speed of individual rear wheels through the precise activation of the rear brakes, slowing an excessively spinning rear wheel to ensure that traction is maintained without causing detriment to the handling – often the case with a mechanical limited slip differential.

The Sport Pack option comprises of a switchable sports mode, sports diffuser, Titanium sports tail pipe, cross drilled brake discs, black callipers and an engine oil cooler. As with all Lotus cars, the Evora is very driver focussed and therefore all the electronic intervention systems can be completely overridden by the driver (apart from the ABS). In standard mode, all the systems above are in operation; pressing the sport button (Sport Pack option only) sharpens the throttle response and increases the engine rev limit. The sports mode traction control is adjusted to give increased slip and yaw angle before intervening, and also removes the understeer recognition.

Keeping a grip – 18 inch at the front, 19 inch at the rear.

Tyre choice is a vital component in the ride, handling and steering performance of every Lotus and for the Evora, Yokohama was chosen as the development partner. Lotus and Yokohama engineers developed bespoke tyres especially for the Evora – a 225/40 ZR18 at the front and larger diameter 255/35 ZR19 at the rear. Both have carcass construction and a rubber compound unique to Lotus and are identified by the letters ‘LTS’ on the sidewalls.

The V6 Engine – dual VVT-i (‘intelligent’ variable valve timing)

The exceptional working relationship that Lotus has enjoyed with Toyota over several decades, combined with the overwhelmingly enthusiastic reception for the company’s four-cylinder power units in the Elise and Exige, guaranteed the Japanese giant’s inclusion on the shortlist for the Evora engine supplier.

The final choice was Toyota’s all-alloy 2GR-FE 3.5-litre V6 DOHC, with dual VVT-i (‘intelligent’ variable valve timing). Lotus has painstakingly developed its own T6e engine management software for this engine to optimise its compatibility with the unique requirements of the Evora to give a peak power output of 280 PS at 6400 rpm, while boosting its maximum torque to 342 Nm at 4700 rpm (prototype specification)*.

Changes to the engine management and exhaust systems also allow the V6 to rev more freely and provide rapid throttle response; feedback from the development team shows that the strength of the engine’s mid-range torque means that gutsy performance will be easily accessible without having to thunder through to the redline. This makes the Lotus Evora a thoroughly satisfying car for everyday road use and a rewarding one when you just want to drive.

The 2GR-FE V6 engine is mated to a manual six-speed gearbox, again Toyota- sourced. A close-ratio version of this gearbox will be an option for the even more sport-focussed driver. Many Lotus owners enjoy the blend of unique performance and efficiency that the brand’s cars offer. True to the Lotus value of “performance through light weight” CO2 emissions are class leading at 205 g/km while fuel consumption on the combined cycle is 8.7 l/100 km. Fuel economy for the urban cycle is 12.4 l/100km with 6.5 l/100km on the extra urban cycle.

What’ll she do?

The zero to 100 km/h sprint takes place in just over 5 seconds with a top speed of over 260 km/h (prototype specification)*.

Test. Test. Then test some more

It’s a global car, so the Evora has been tested around the world. From the icy wastes of the Arctic to the heat of the Australian desert, the high altitude of the Alps as well as the country roads around the Hethel factory.

A cross functional team comprising of design, CAE and test and development engineers have been able to develop the Evora into a class leading vehicle in an exceptionally short space of time. It has spent hours howling around the Nürburgring and endlessly lapped Lotus’s test track at Hethel. By the time the Evora entered production in February 2009, prototypes had travelled for hundreds of thousands of miles along some of the worst public roads in the world and been tortured for as many miles on some of the toughest proving grounds the motor industry has to offer, including extreme pave tests.

It has been flung into barriers at low and high speeds, at a multitude of angles, it has even had its roof and doors compressed! By the time the Evora reaches the UK and Europe Lotus showrooms from May 2009, it will be the most thoroughly tested Lotus car in the history of Lotus. It will also be one of the company’s great milestones.

Porsche 911 GT3 RSR

Stuttgart. Kräftig überarbeitet geht der erfolgreiche Porsche 911 GT3 RSR in das neue Modelljahr. Der stärkste Rennwagen auf Basis des Porsche 911, der in der vergangenen Saison unter anderem die American Le Mans Series und die 24 Stunden am Nürburgring gewinnen konnte, geht in der Klasse GT2 bei internationalen Langstreckenrennen an den Start. Deutlichstes Erkennungszeichen des GT3 RSR ist die neu gestaltete Frontpartie mit großflächigen Entlüftungsöffnungen auf der Fronthaube. Doch auch unter der Leichtbau-Karosserie wurde der schnellste Elfer kräftig überarbeitet.

Bereits auf den ersten Blick fallen die Entlüftungsschlitze, die so genannten Louvers, in der Fronthaube ins Auge: Ein Hinweis auf die komplett erneuerte Luftführung der Kühler, die durch die Neuauslegung von Zu- und Abluft bei Verbau der optional erhältlichen Klimaanlage nötig wurde. Die Aerodynamik im unteren Heckbereich wurde weiter optimiert. Der Heckflügel verfügt nun über einen erweiterten Verstellbereich. Die im Vergleich zum Vorgängermodell gewichtsoptimierte Bremsanlage und der leichtere Fahrzeugkabelstrang sorgen zusätzlich für eine verbesserte Fahrdynamik.

Der Hubraum des bekannt effizienten Sechszylinder-Boxermotors wuchs von 3,8 auf nun 4,0 Liter. Der Motor leistet nach einer erneuten Reduzierung des Luftmengenbegrenzers zur Saison 2009 nun rund 450 PS (331 kW) bei 7.800 Umdrehungen pro Minute und entwickelt ein maximales Drehmoment von 430 Nm bei 7.250 Umdrehungen pro Minute. Der Drehzahlbegrenzer des effizienten Sechszylinders setzt bei 9.000 Kurbelwellenumdrehungen ein. Im Vergleich zum Vorgänger konnte das Drehzahlniveau bei gleicher Leistung signifikant reduziert werden. Dadurch weist der Motor einen optimierten Drehmomentverlauf und eine verbesserte Fahrbarkeit auf.

Im Cockpit weist eine neue Multifunktionsanzeige oberhalb des Armaturenträgers den Fahrer auf den optimalen Schaltpunkt hin. Ebenfalls neu ist das programmierbare Multifunktions-Bordnetzsteuergerät, das den Einsatzteams viele individuelle Funktionen zur Verfügung stellt. Dazu gehört unter anderem die frei wählbare Blinkfrequenz der Lichter in der Frontschürze, die auch bei Dunkelheit die frühzeitige Differenzierung der Fahrzeuge bei der Anfahrt zur Box gewährleistet. Auch die Servicefreundlichkeit im Rennbetrieb wurde weiter verbessert. Der GT3 RSR verfügt nun über eine neue Luftheberanlage mit Überdruckventil. Die Ölschnellbefüllung wanderte auf den Heckdeckel, wo sie beim Boxenstopp für die Mechaniker besser zugänglich ist.

Neben dem GT3 Cup und dem GT3 Cup S ist der GT3 RSR das dritte Rennfahrzeug auf Basis des Porsche 911, das von Porsche Motorsport angeboten wird. Der erfolgreiche Langstreckenrenner aus Weissach wird in einer Auflage von rund 20 Fahrzeugen produziert und ab sofort an die Kunden-Teams in aller Welt ausgeliefert. Der Preis für den GT3 RSR beträgt 380.000 Euro zuzüglich der länderspezifischen Mehrwertsteuer.

The 2009 Model Year Lotus Exige Cup 260

Extensive use of carbon fibre and lightweight components for the latest homologated-for-the-road Lotus Exige Cup 260

Front - Lotus Exige Cup 260

Lotus Cars Ltd, has unveiled the MY2009 Exige Cup 260. A direct development of the 2008 Exige Cup Car, this year’s car uses advanced light weight components and carbon fibre body material, to reduce the overall weight by 38 kg to a total mass less than 900 kg. Maximum power output of 257 hp (260 PS), remains the same as the 2008 car, but with careful attention to weight reduction detail, the 2009 Model Year Exige Cup 260 provides a more agile and dynamic track focused drive and is more than capable of taming Europe’s most challenging race circuits. Unusually for such a focused track and road machine, the 2009 Model Year Exige Cup 260 is fully homologated for road use in Europe and key markets in Asia – a must have for many race competition programmes where a road legal car has to be entered. The Lotus Exige Cup 260 is also eligible to compete in the newly announced 2009 Lotus Cup Europe race series organized and run by LoTRDC. The Exige Cup 260 exploits the Lotus philosophy of using weight reduction to increase performance and reduce emissions. Mike Kimberley, Chief Executive of Group Lotus commented, “Lotus is now recognised globally as one of the leaders in the green automotive revolution. Colin Chapman, the founder of Lotus is attributed as saying “Adding power makes you faster on the straights; adding lightness makes you faster everywhere” and this statement is more relevant today than it ever has been, as decreasing weight increases the car’s performance and most importantly efficiency.”

Back - Lotus Exige Cup 260

The Exige Cup 260 follows this philosophy closely – the weight saving programme has looked at all areas of the car where components can be replaced with a lighter version (without pushing the costs beyond the reach of the serious track day driver or clubman racer) or where components can be removed completely without detracting from the purity of the driving experience:

Carbon fibre (resulting in a weight saving of 12kg):
• Roof Panel
• FIA and HANS compliant Driver and Passenger Seats*
• One piece Carbon Fibre Dash Top Panel
• Rear Tailgate
• Front Access Panels
• Front Splitter
• Side air intake ducts
• Rear Spoiler

Lightweight components (resulting in a further weight saving of 22kg):
• Lightweight ‘Motorsport’ Battery
• Ultra-light 12 Spoke Forged Alloy Wheels
• Revised Rear Engine Subframe with lightweight Coating
• Lightweight Fly Wheel
• Lightweight composite bulkhead panel replaces rear window
• Alloy Supercharger U bend pipes
• Footwell Pads

Inside - Lotus Exige Cup 2600

Removing some other non essential components and equipment such as the interior and boot carpets, front mudflaps, battery cover, interior mirror, sunvisors, rear tailgate gas strut, results in a further weight saving of 4kg. However, should a customer wish, air conditioning and an interior noise reduction pack are available, together with the complete range of Lotus metallic, lifestyle and premium paint colours. The MY2009 Exige Cup 260 weighs in at just 890 kg, giving an impressive power to weight ratio of 288 hp / tonne (291 PS / tonne). But, of course, power to weight alone does not make a highly competitive race or track car, so in addition, the Exige Cup 260 has a formidable list of standard performance focused equipment, as follows:

Wheels and Tyres
Ultra lightweight wheels, that reduce the unsprung mass and contribute a weight saving of approximately 10 kg (22 lbs) over the already super light forged Exige wheels, are shod with Lotus specific LTS construction and compound Yokohama A048 LTS tyres to maximise grip and achieve the ride and handling targets set by Lotus Engineering.

Safety Equipment

Breaks - Lotus Exige Cup 260

Lotus Exige Cup 260 cars have the safety equipment expected of a race car, with FIA and HANS compliant carbon fibre lightweight sports seats*, normal 3-point “Webb Lock” harnesses (four or six point driver and passenger seat belt harnesses are available for track use only). (* The seats are FIA compliant when fitted in conjunction with fixed seat runners that are available as a track only dealer fit option). A high tensile steel roll over hoop is now fitted with a body coloured Lotus Sport A- Frame as standard and the chassis is already pre-drilled to fit a full front roll cage – a simple dealer fit process involving just the removal of the roof panel for access prior to fitting. Completing the additional safety equipment is a FIA compliant electronic ignition kill switch, with cockpit and external activation, and a FIA compliant plumbed electrically activated fire extinguisher system, again with cockpit and external switches. Like all current Lotus cars, the Exige Cup 260 is built around a very strong extruded and bonded aluminium chassis tub. Attached to the chassis is a sacrificial energy absorbing composite front structure designed to help absorb crash energy in the event of impact.

Lights - Lotus Exige Cup 260

Suspension
Eibach springs, one way adjustable Bilstein dampers and a stiffened and adjustable front anti-roll bar allows customers to tailor the handling characteristics of the car to their own requirements. As the Exige Cup 260 cars are equipped for track use, a double shear track control arm brace is provided to cope with the expected kerb abuse during racing or hard track day driving.

Brakes
The brake system includes large diameter 308 mm 2-piece aluminium belled cast iron cross-drilled and ventilated front discs and 282 mm cross-drilled and ventilated discs at the rear, upgraded Pagid RS14 sports brake pads set into the brake calipers (AP Racing two piece radially mounted, 4 piston at the front and Brembo sliding at the rear), and stainless steel braided brake hoses – all linked to the proven Lotus track tuned servo-assisted four-channel ABS system that enhances braking performance and minimizes stopping distance without taking over from the skill of the driver.

Performance, Economy and Emissions
The Exige Cup 260 is one of the quickest road cars around a circuit. Key to this incredible performance is the aerodynamic package, which produces over 40 kg of downforce at 160 kmh increasing grip and stability at higher speeds. With a top speed of circa 245 kmh (152 mph) and a zero to 160 kmh (100 mph) in circa 9.9 seconds, 0 to 100 kmh in circa 4.1 seconds (0 to 60 mph in circa 4 seconds), the MY2009 Exige Cup 260 is the perfect partner for the serious racer. Combined Fuel Consumption is 9.1 l/100km and the CO2 emissions 216 g/km.

Rear - Lotus Exige Cup 260

Engine
The supercharged and intercooled engine in the Exige Cup 260 has a maximum power output of 260 PS (257 hp) at 8000 rpm and a torque figure of 236 Nm (174 lbft) at 6000 rpm. This significant amount of extra power and torque now available together with the VVTL-i variable cam system ensures that there is a smooth and linear delivery of power from low engine speeds all the way to the maximum 8000 rpm (8500 rpm transient for 2 seconds). The Roots-type Eaton M62 supercharger (with a sealed-for-life internal mechanism meaning that it does not require the use of the engine’s oil) is run from the crankshaft and has an integral bypass valve for part load operation. Charge air (air under pressure from the supercharger) is cooled through an air-to-air intercooler (the air enters via the enhanced roof scoop) before being fed into the engine itself. All charge air ducting has been kept as short as possible with large diameter pipes to minimise restriction and maximise throttle response and efficiency. Four high capacity injectors and an uprated fuel pump add additional fuel under hard acceleration or continuous high speed driving. A lightweight flywheel is fitted (giving even greater flexibility and response to the gear change), a sports-type clutch plate and heavy duty clutch cover transfer the engine power and torque to the lightweight C64 six-speed gearbox (with an aluminium casing) – with the same perfectly spaced ratios as the Exige S. A torque-sensing limited slip differential is fitted as standard, with a plate type limited slip differential available as an option. An Accusump (engine oil accumulator unit) is included in the whole package as an oil reservoir back-up for extreme track use ensuring that, under those conditions, the engine oil pressure remains constant. Electrical supply is provided by a lightweight motorsport battery which saves a massive 5 kg of weight sitting behind the rear axle – again weight saving is not just the removal of mass but ensuring that this mass is removed where it most effects performance and handling.

Detail - Lotus Exige Cup 260

Lotus Launch Control and Lotus Traction Control
Keen to pass on lessons learned on the track with the Exige GT3 racing programme, Lotus Sport has contributed another important technology – launch control combined with variable traction control. This combination has already made its production debut with the track-oriented Lotus 2-Eleven. The launch control allows the driver to determine the number of revs they wish to use during a standing start. Having programmed that limit, the driver then holds their foot down fully on the throttle pedal and sidesteps the clutch pedal for a very quick departure from the line. The clutch damper cushions the severity of the clutch to transmission engagement to minimise the stresses to the drivetrain. The launch control also keeps wheel-spin at bay until 6 mph, after which the traction control assumes its duties. As with launch control, the driver can control the amount of traction control you require from the driver’s seat, altering it on the move to suit the characteristics of particular corners. The amount of traction control can be varied in over 30 increments from an optimum 7 percent tyre slip to completely off. The message display in the new instrument pack displays what degree of traction control you have currently dialled in.

Power and torque curves

Roof Scoop
For 2009, the Lotus Sport Exige Cup 260 now has a high flow, full-length carbon roof scoop as part of the lightweight carbon roof panel, which not only saves 4 kg but also ensures efficient cooling through the intercooler, which in turn allows the Exige Cup 260 to gain a higher charge density in the cylinders.

Auf dem „Schalke Tag“ mit mehr als 100.000 Besuchern am 20. Juli 2008 wird der Polo „S04-Edition“ allen Fans zur Saisoneröffnung 2008/2009 in der endgültigen Version vorgestellt.

With its stunning visual impact, exhilarating all-round dynamic performance, innovative chassis technology and high levels of luxury, packaging and convenience, the Evora heralds an exciting new era for Lotus.

The first all-new Lotus since the iconic Elise made its debut in 1995, The Evora enters the sports car market as currently the world’s only mid-engined 2+2. Powered by a Lotus-tuned 3.5-litre V6 engine producing 280 PS, and weighing just 1350 kg (prototype specification), the Evora promises breathtaking performance. During preliminary testing around the famous Nürburgring, the Lotus chassis engineers report that it is extremely agile and great fun to drive – even when clad with the full development disguise that hid the beautiful lines from the prying motor-industry paparazzi.

In addition to its excellent performance and exemplary handling, the Evora offers a more refined ownership experience than Lotus’s existing smaller four- cylinder models. Its elegantly styled cabin is elegantly trimmed and its equipment list includes contemporary features such as an advanced touch- screen multi-media system and electric power-fold door mirrors.

Because one of the roles of the Evora is to attract new customers to the Lotus brand, much attention has been paid to its ease of use. Wider, taller door apertures and narrower sills make getting in and out of the cabin a less athletic undertaking than it is in Lotus’s smaller sports cars (the Elise, Exige, Europa and 2-Eleven), while the design of the cabin itself will accommodate two 99th percentile (6ft 5in tall) American males in the front seats.

The ‘convenience factor’ of the Evora extends to less obvious areas of the car. For instance, beneath the skin the entire front-end structure is a high tech aluminium sacrificial modular unit, attached to the main extruded aluminium tub. This modular unit is designed to deform for maximum safety, and to reduce repair costs in the event of a frontal impact.

The Evora has been designed with global automotive regulations in mind, and future derivatives are planed, these including amongst others, a convertible.

The Evora will be hand crafted and built on a dedicated new assembly line within Lotus’s advanced manufacturing facility at Hethel in the east of England; capacity limitations will restrict production to approximately 2000 cars a year, ensuring the dynamic new sports car’s rarity and exclusivity.

Mike Kimberley, CEO of Group Lotus plc, has this to say about the exciting new model: “The Evora is the biggest milestone Lotus has achieved since the Elise was born 13 years ago and is part of our bold five year strategic plan, which includes the introduction of new cars and technologies to many more markets around the world. The Evora also represents Lotus core values of performance through light weight and efficiency and proves that you can have phenomenal performance, fuel efficiency elegant design and practicality all in a class leading mid-engine 2+2 sportscar, which will meet global safety and homologation standards” Mike Kimberley continues, “Looking to the future, we will continue to research, develop and produce lighter, more efficient vehicles which are linked to our extensive and well-regarded work on all aspects of future fuels, alternative engines and electric and hybrid vehicle solutions for the future. We all have an environmental responsibility to future generations and the Evora is another example where Lotus is seen to make significant steps towards improving the efficiency and sustainability of the motorcar keeping Britain at the forefront of the high technology motor industry.”

THE EVORA IN DETAIL

Style or function? Have both…

Designed ‘in-house’ by Lotus Design, the sleek and athletic form uses fluid forms and crisp surfaces to communicate velocity, agility and sophistication. Low and wide with modern cab forward proportions, muscular rear haunches and function optimised hip air intakes this is clearly a serious mid engined sportscar that skilfully hides the practicality of its two plus two capability.

Russell Carr, Head of Lotus Design, led the Evora’s design team with Steven Crijns, Design Manager responsible for the exterior and Anthony Bushell, Senior Designer, responsible for the interior.

“A cornerstone of the design’s success was working closely with the technical team to develop a package that allowed us to get the proportions correct,” says Head of Design Russell Carr, “The asymmetric wheel sizes, the short rear overhang, long front overhang and cab forward visor screen all contribute to giving the car visual movement and an agile stance. This is incredibly important to us because we want the car’s aesthetics to communicate its driving characteristics”.

Lotus products have always embodied a perfect balance between form and function and the Evora successfully continues this heritage. “We never lost sight of the fact that, although this car must provide real world useability, sportscars are emotional purchases and that you have to seduce the customer through beguiling looks and exotic persona. We are, therefore, very proud that we have been able to use technical and user functionality to positively drive the design in key areas and create some of the car’s most distinctive features”. says Carr.

Ingress and egress, for example, dictated a minimal “step-over” to get into the Evora. We simply cut away the surface under the door and created a unique and dramatic piece of sculpture that enhances the stance of the car as well as its useability.

Elsewhere, aerodynamic considerations for drag, down force and cooling had significant but positive influence on the overall form and details such as air intakes. A desire to create balanced down force, that increases cornering performance, led to the adoption of, the now, “signature” top exit radiator vent, race car inspired diffuser and “floating rear wing”. Drag limitation, drove the dramatic tear-dropped cabin layout and the curvaceous plan view has given the car a more muscular rear shoulder and conveys a level of sophistication appropriate to this market segment.

“We believe that our designs should be honest as well as dramatic and so we are really pleased with the fact that these iconic features all do a real job” says Steven Crijns, Design Manager.

This inherent understanding of the relationship between the technical and the aesthetic paid dividends the first time a full-scale model of the Evora was wind- tunnel tested – only minimal adjustments were required to the car’s aerodynamic package to meet the targets for downforce and stability.

Steve Crijns continued, “Overall the design language shows a clear DNA link with its Lotus siblings, whilst establishing its own distinctive and contemporary theme. The undulating shoulder line is brilliantly mirrored in the lower part of the bodyside by the cut -away sill that creates a torseau-like muscularity.”

“The front three-quarter view is really powerful” Russell Carr continues, “Your eye is drawn effortlessly, from our signature mouth, rearward by fluid surfaces and fast lines that create a sense of speed even when the car is stationary. From this angle you can also see how dramatically the visor screen sweeps around the teardrop form of the cabin and the gently waisted plan shape perfectly accentuates the muscularity of the rear fender. This is unmistakeably mid engined language and the Evora is unmistakeably a Lotus.”

The view from the rear three-quarters is just as striking and the one that many will become familiar with as the car passes them on the road. The tapered cabin, diffuser, floating wing, centrally mounted twin tailpipes and distinctive engine bay vents all combine to create a completely unique look.

Moving right inside…

The design language of the interior reflects that of the exterior – simple, fluid surfaces, soft forms and crisp feature lines wrap around the cabin cosseting the occupants. Unlike recent Lotus products that use a race car inspired, technical minimalism, the Evora employs a softer approach that utilises premium quality materials and finishes to create a contemporary but luxurious ambience that is unique to Lotus products.

It is, according to Head of Lotus Design Russell Carr, “A huge departure from what people might expect based on Lotus’s recent past. We wanted the Evora’s cabin to feel special and to be surprising as well as sporty. Precision engineered metal inserts and quality edge-lit switches are brilliantly juxtaposed against soft hand-stitched leather surfaces to give a modern interior with a classic twist.”

Russell Carr continues, “The flat bottomed steering wheel, figure hugging sports seat, contemporary instrumentation and ergonomically positioned controls provide an intuitive environment that instantly forms a connection between driver and car ensuring that it becomes an extension of his or her body.“

Anthony Bushell Senior Designer explained about the choice of materials in the Evora’s interior, “Tactile quality is incredibly important within this segment and so we wanted the interior to use honest premium materials. Much of the switchgear is bespoke, and every metallic component is actually metal.”

Focused courtesy lighting is used throughout the interior, giving a spectacular illuminated feel to the sculpture design feature of the cabin. The extensive use of handcrafted, premium leather differentiates The Evora from other Lotus products and such is its importance to the character of the car that an entire new trim shop has been built at the Lotus Headquarters in the UK, dedicated to its production.

Even the entry level versions of the Evora will feature leather-upholstered seats, upper door trim panels and facia, but it is expected that most customers will opt for the full hide treatment. With a range of leather colours available, customers will have the opportunity to personalise their Evora.

High-tech treats

Contemporary technology also features in the Evora’s cabin. A newly developed Alpine multi-media system with a 7 inch touch-screen provides advanced audio, satellite navigation, video, Bluetooth® hands-free telephone and iPod® connectivity functions; the screen also serves as a monitor for The Evora’s optional reversing camera. The satellite navigation element of the system is removable, allowing you to programme it from the comfort of your home, or take it with you to continue your journey in an unfamiliar pedestrian location.

The Alpine audio set-up is one of the most sophisticated automotive systems in the world. Called IMPRINT and using MultEQ sound enhancement technology, it is able to cancel out sound imbalances, caused by the cabin window glass, for instance, creating echoes, while carpets suppress mid-range frequencies – resulting in amazingly crisp, clear, undistorted sound reproduction wherever you are seated in the car.

A bespoke air-conditioning system developed by Bergstrom is standard on all models, and has been designed for the hottest climate or the closest humidity to help provide maximum occupant comfort. Lotus traction control and on- board tyre pressure monitoring will also be available.

One size fits all

The front seats themselves are very supportive and leather clad with a lightweight manual adjustment mechanism for fore and aft, rake and lumbar, designed to give a supported driving position.

The rear seats of 2+2 versions of the Evora –are intended for children and smaller adults. There will also be a two-seater derivative with a luggage shelf in the back. To maximise comfort in the rear, there’s a decent amount of foot- room under the seats in front, while both back seats feature ISOFIX mountings for secure child seat fitment.

When unoccupied, the rear seats provide a convenient stowage area, adding to the Evora’s appeal as an everyday car. The 160 litre boot, which ingeniously features a fresh air cooling system to reduce the effect of any heat ingress from the engine bay, will also accommodate a full set of golf clubs.

Easy in, easy out

With the Elise and its derivatives, the no-compromise character of the car makes getting in and out across a wide sill and through a comparatively narrow door/window aperture part of the charm of ownership. For the Evora and its remit for the serious daily driver, and to attract newcomers to the Lotus brand, greater convenience and practicality is provided.

As a consequence the sill is now lower and slimmer (80mm wide compared with 100mm in the Elise), and the whole door aperture taller. The doors open wider than on the Elise and its siblings, while the height of the front seat is raised by 65mm.

But while The Evora is undeniably more ‘lifestyle’ in respect of its everyday practicality, once you’re seated behind its flat-bottomed steering wheel, it feels every bit as exotic and sporting as you would expect a Lotus to be.

Safely does it

In common with the Elise and its derivatives, The Evora’s bonded extruded aluminium chassis tub has incredible inherent strength, particularly in regard to side impacts. Additional torsional strength is given to the whole structure by the tubular steel seatbelt anchorage frame that also acts as a rollover structure.

Deformable sacrificial aluminium front and steel rear subframe modules are attached to the tub using joints which are designed to minimise damage to the tub, protecting the main passenger cell in the event of an accident.

Driver and passenger airbags are standard. The airbag on the passenger side is cleverly engineered to deploy vertically and then be deflected rearwards by the windscreen, to provide protection for children as well as adults.

Anti-lock brakes are standard on all models, as is Lotus Traction Control (LTC); these systems have been specially developed in co-operation with Bosch and enable up and coming drivers to consistently exploit the braking and acceleration capabilities of the Evora, whilst allowing skilled enthusiasts the freedom to enjoy the full Lotus driving experience.

The chassis: Production Low Volume Versatile Vehicle Architecture The Evora’s chassis is an evolution of the Versatile Vehicle Architecture (VVA) from the Lotus APX concept vehicle previously showcased at the Geneva Motorshow, and allows for the development of a range of vehicles up to a gross vehicle weight of 1,900 kg. This architecture has been designed to be more applicable to mid-volume applications by utilising our low capital investment manufacturing processes. The Evora structure progresses the Lotus ‘bonded and riveted’ technology used in the Elise family of vehicles with unique extrusions and folded panels, whilst providing contemporary ease of ingress/egress, build modularity and improved, lower cost repairs.

The Low Volume VVA architecture has been designed so that it can be extended in width, length and height. The strength and stiffness of the low volume VVA chassis can be modified cost effectively by varying the wall thickness of the extrusions, without altering the exterior dimensions. The ability to lengthen or shorten extrusions with the option to tailor the chassis stiffness, vastly increases the number of vehicles that can be developed from this vehicle architecture. Front and mid engine installations have been considered, as well as hybrid and Electric Vehicle (EV) applications.

The Lotus Evora employs a composite roof as a stressed structural member to give an exceptional vehicle stiffness of 26,000 Nm per degree, thanks in part to the seatbelt anchorage frame’s secondary function as a roll over structure, and partly because the high-tech composite body panels are stressed items. However, despite this high stiffness, the complete chassis and modules weight just 200 kg (prototype weight), helping to keep the weight of the whole car to just 1350 kg (prototype weight).

To deliver this high performance structure, bonded and riveted high grade aluminium extrusions and simple and elegant folded sheet elements are used in the lower structure, building upon award winning research projects in this field. Lotus pioneered the technology of bonded aluminium extrusions for use in road vehicles and has successfully developed high performance cars for other car companies around the world.

The central tub is attached to an extruded aluminium subframe at the front and a lightweight welded steel subframe at the rear. These subframe modules also offer advantages in terms of convenience and low cost of repair, and during manufacturing can be brought to the production line fully assembled, ready to be attached.

The high technology Lotus Evora chassis will be manufactured at the new Lotus Lightweight Structures facility in Worcester, UK. LLS employs 120 skilled engineers, technicians and sales staff and will manufacture all the Lotus aluminium structures, including those for the Elise, Exige, 2–Eleven and Europa and aluminium and composite structures and components for Lotus’s extensive global client base.

Suspended & animated

The Evora suspension wishbones are forged from aluminium to reduce the unsprung mass. These are similar in weight, and stiffer than the steel items found on the much smaller Elise, Exige and Europa vehicles, and have a far higher vehicle weight capacity. They are attached to the front and rear modules via bespoke bushes. The Evora will use Bilstein high performance dampers and Eibach springs with unique dual path top mounts for optimised vehicle refinement. Hydraulically assisted power steering is provided by a Lotus tuned TRW steering rack.

All in all, the Evora delivers. It has incredible Lotus handling and provides unsurpassable driving pleasure. In fact, word from the ride and handling team is that the new car is likely to become a class standard-setter for speed and agility.

Stop right now…

Vented and cross-drilled brake discs – massive 350mm items on the front and 332mm at the rear – and high performance bespoke Lotus AP Racing 4 pot callipers ensure impressive stopping power.

Everyone connected with the brake testing programme, conducted on the punishing corners, climbs and descents of the Nürburgring, has described the brakes as ‘phenomenal’ with excellent thermal performance and outstanding feel even after extended sessions of extreme use.

Part of that testing programme was to finalise settings for the ABS system being developed in conjunction with Bosch. The system is set to very high thresholds and operates so progressively that drivers are often unaware that they have actually triggered the ABS.

Safe. Fun. Lotus Traction Control

The Switchable Lotus Traction Control (LTC) system has been developed simultaneously with the ABS and works through the engine management system to reduce power when required to maintain traction. Unlike many traction control systems, LTC has been tuned to complement the skills of the driver without taking over. The Lotus LTC is active above 5 mph (8 km/h) and operates much more quickly than many brake based systems. The system can be deactivated completely, giving no traction control intervention.

Keeping a grip – 18 inch at the front, 19 inch at the rear. Tyre choice is a vital component in the handling performance of every Lotus and for the Evora, Yokohama was chosen as development partner.

Lotus’s long-term relationship with Yokohama was swiftly rewarded during development when initially the front tyre size did not generate the Lotus required lateral grip, the Japanese grip gurus went away and developed bespoke tyres especially for the Evora – a 225/40 ZR18 at the front and larger diameter; 255/35 ZR19 at the rear. Both have carcass construction and a rubber compound unique to Lotus and are identified by the letters ‘LTS’ on the sidewalls.

The V6 Engine – dual VVT-i (‘intelligent’ variable valve timing) The exceptional working relationship that Lotus has enjoyed with Toyota over several decades, combined with the overwhelmingly enthusiastic reception for the company’s four-cylinder power units in the Elise and Exige, guaranteed the Japanese giant’s inclusion on the shortlist for the Evora engine supplier.

The final choice was Toyota’s all-alloy 2GR-FE 3.5-litre V6 DOHC, with dual VVT-i (‘intelligent’ variable valve timing). Lotus has painstakingly developed its own T6e engine management software for this engine to optimise its compatibility with the unique requirements of the Evora to give a peak power output to 280 PS at 6400 rpm, while boosting its maximum torque to 342 Nm at 4700 rpm (prototype figures).

Changes to the engine management and exhaust systems also allow the V6 to rev more freely and provide rapid throttle response; feedback from the development team suggests that the strength of the engine’s mid-range torque means that gutsy performance will be easily accessible without having to thunder through to the redline. This makes the Lotus Evora a thoroughly satisfying car for everyday road use and a rewarding one when you just want to drive.

The 2GR-FE V6 engine is mated to a manual six-speed gearbox, again Toyota-sourced. A close-ratio version of this gearbox is also currently under development for the even more sport-focussed driver. Many Lotus owners enjoy the blend of unique performance and efficiency that the brand’s cars offer. True to the Lotus value of “performance through light weight” CO2 emissions are expected to be a class leading sub-225 g/km (prototype figures) while testers report fuel consumption in the region of 30+ mpg (pending formal homologation testing).

What’ll she do?

At the time of its unveiling, full performance figures have yet to be compiled on a production specification Lotus Evora, Lotus has another 6 months development to conduct.

While for Lotus top speed is of less importance than stability at speed, early indications suggest a maximum speed of 160 mph; the 0-60 mph sprint from standstill is estimated at sub 5 seconds (prototype figures).

Test. Test. Then test some more

It’s a global car, so the Evora has been tested around the world. From the icy wastes of the arctic to the heat of the desert, the high altitude of the Alps as well as the country roads around the Hethel factory.

It has spent hours howling around the Nürburgring and endlessly lapped Lotus’s test track at Hethel. By the time the Evora enters production, prototypes will have travelled for hundreds of thousands of miles along some of the worst public roads in the world and been tortured for as many miles on some of the toughest proving grounds the motor industry has to offer including extreme pave tests, to Australia and even the Arizona outback.

It has been flung into barriers at low and high speeds, at a multitude of angles, including head-on; it has even had its roof compressed!

By the time the Evora reaches the Lotus showrooms from Spring 2009 onwards, it will be the most thoroughly tested Lotus car in the history of Lotus. It will also be one of the company’s great milestones. The order book is now open in the UK and across continental Europe, with markets around the world to start taking orders in due course. Final specifications, options and prices of the production Lotus Evora will be published closer to the sale date in the many Lotus markets around the world.

Mike Kimberley, Chief Executive of Group Lotus plc sums up, “This year Lotus celebrates its 60th anniversary and it is fitting that 2008 is also the birth of the Lotus Evora, a fantastic addition to the Lotus range. The Lotus Evora represents Group Lotus, a company that is at the forefront of the automotive industry, in a changing world where priorities of efficiency, economy and environmental impact go hand in hand with performance, design and individuality. I think Colin Chapman would have approved.”

Porsche GT3 RSR
Mit umfangreichen Modifikationen geht der Porsche GT3 RSR in das neue Modelljahr. Der stärkste Rennwagen auf Basis des Porsche 911, der in der vergangenen Saison unter anderem Klassensiege bei den 24-Stunden-Rennen in Le Mans und Spa sowie den Gesamtsieg bei den 24 Stunden Nürburgring feiern konnte, geht in der Klasse GT2 bei internationalen Langstreckenrennen an den Start. Deutlichstes Erkennungszeichen des neuen GT3 RSR ist die aerodynamisch stark verbesserte Frontpartie. Die meisten Innovationen stecken jedoch unter der gewichtsoptimierten Karosserie.

Neben den gut sichtbaren Zusatzspoilern an der Frontschürze, den so genannten Flicks, sorgt eine optimierte Luftführung mit neu gestalteten seitlichen Luftauslässen für mehr Abtrieb bei gleichzeitig reduziertem Luftwiderstand. Der Heckbereich samt Heckflügel wurde vom Vorgängermodell übernommen. Umfangreiche Änderungen an der Fahrwerks-Kinematik sorgen für deutlich erhöhten mechanischen Grip. Auch die Einstellmöglichkeiten am Fahrwerk wurden erweitert.

Der 3,8-Liter-Boxermotor des GT3 RSR blieb bis auf leichte Detailverbesserungen unverändert. Er leistet 465 PS (342 kW) bei 8.000 Umdrehungen pro Minute und entwickelt ein maximales Drehmoment von 430 Nm bei 7.250 Umdrehungen pro Minute. Der Drehzahlbegrenzer des effizienten Sechszylinders setzt bei 9.400 Kurbelwellenumdrehungen ein.

Eine Menge Know-how aus dem Sportprototypen RS Spyder steckt im völlig neuen Getriebe des GT3 RSR. Das von Porsche-Ingenieuren entwickelte sequenzielle Sechsgangetriebe ist wesentlich leichter als die im Vorgänger verbaute Schaltbox und weist eine deutlich reduzierte innere Reibung auf. Der flachere Winkel zu den Achswellen erlaubt den Teams einen größeren Spielraum bei der Fahrwerkseinstellung.

Neben dem GT3 Cup und dem GT3 Cup S ist der GT3 RSR das dritte Rennfahrzeug auf Basis des Porsche 911, das von Porsche Motorsport angeboten wird. Der, vom exklusiven Sportprototypen RS Spyder abgesehen, schnellste und stärkste Langstreckenrenner aus Weissach wird in einer Auflage von rund 35 Fahrzeugen produziert und ab sofort an die Kunden-Teams in aller Welt ausgeliefert. Der Preis für den GT3 RSR beträgt 349.800 Euro zuzüglich der länderspezifischen Mehrwertsteuer.

Latest Track Car From Lotus Offers ‘Straight Out Of The Box’ Thrills

Model Year 2008 Lotus Sport Exige Cup 260

Lotus Sport, the motor sport division of Lotus Cars Ltd, has unveiled the MY2008 Lotus Sport Exige Cup 260. A direct development of the 2007 Exige Cup Car, this year’s car has a revised engine management system to take the maximum power output to 257 hp (260 PS), up by nearly 5 hp (5 PS) over last year. Bespoke performance enhancements created to offer a car with even greater levels of handling and acceleration capable of taming Europe’s most challenging race circuits. The Exige Cup 260, once again represents Lotus’ most radical version of the Exige, with the track environment being its home and for 2008, the Lotus Sport Exige Cup 260 has full European homologation for road use (a must have for some competitive environments where a road legal car has to be entered). There are further product changes: all Lotus Sport Exige Cup 260 cars now have a number of the 2008 Model year improvements from the road versions of the Elise and Exige, namely:

• Instrument pack with new graphic design and expanded functionality
• New alarm/immobiliser + single integrated function key
• Variable Lotus Traction Control
• Variable Lotus Launch Control

In traditional Lotus style, weight saving is paramount. Weighing in at just 928 kg, the power to weight ratio is an impressive 271 hp / tonne (273 PS / tonne). Such a fantastic power to weight ratio alone of course does not make a superlative track car, so the Exige Cup 260 has a formidable list of standard equipment that includes Lotus specific LTS compound Yokohama A048R tyres, 4-piston AP Racing front brake calipers, adjustable dampers and anti-roll bar, the latest FIA 6-point roll cage and sports driver and passenger seats. The car can also be ordered as a Track version for track use only. The Track Version comes pre- fitted with an FIA approved 6-point roll cage, and 4-point harnesses. In addition, a wide range of motorsport specific options are also available with this version.

• 70 litre fuel cell (FIA approved)
• Yokohama A005 racing slick tyres with Hi-Power silver 5-spoke ultra lightweight
• forged alloy wheels
• C64 6-speed gearbox with dog engagement and revised ratios
• 1.5-way adjustable plate-type limited slip differential
• Race specification battery with battery tray
• De-cat pipe
• Level 2 stainless steel sports exhaust – 104.0 dB(A)
• Black race seat – driver only (FIA approved)
• Black 6-point harnesses – driver only (FIA approved)

The Lotus Sport Exige Cup 260 is one of the quickest cars around a circuit. Key to this incredible performance is the aerodynamic package, which produces over 40 kg of downforce at 160 kmh increasing grip and stability at higher speeds. With a top speed of 247 kmh (147 mph) and a zero to 160 kmh (100 mph) in circa 9.9 seconds, 0 to 100 kmh in circa 4.1 seconds (0 to 60 mph in circa 4 seconds), the MY2008 Exige Cup 260 is the perfect partner for the serious racer. Combined Fuel Consumption is 9.1 l/100km and the CO2 emissions 216 g/km. The Exige Cup 260 is available now for sale in mainland Europe at 56,034, exclusive of local taxes and on the road charges. You will find the individual retail prices for some major European markets in a separate list at the end of this release.

Mike J Kimberley, Chief Executive Officer Group Lotus plc said:

“In keeping with our racing and high performance sports car heritage, we are very pleased to launch this exceptionally exciting, phenomenal-handling Lotus Sport Exige Cup 260. This is yet another example of how Lotus Cars and high-tech engineering with Lotus Sport, can transform an already brilliant road car into an exceptionally high performance product for the track.”

Further details about the Lotus Sport Exige Cup 260:

Engine

The supercharged and intercooled engine in the Exige Cup 260 has a maximum power output of 260 PS (257 hp) at 8000 rpm and a torque figure of 236 Nm (174 lbft) at 6000 rpm. This significant amount of extra power and torque now available together with the VVTL-i variable cam system ensures that there is a smooth and linear surge of power from low engine speeds all the way to the maximum 8000 rpm (8500 rpm transient for 2 seconds). The Roots-type Eaton M62 supercharger (with a sealed-for-life internal mechanism meaning that it does not require the use of the engine’s oil) is run from the crankshaft and has an integral bypass valve for part load operation. Charge air (air under pressure from the supercharger) is cooled through an air-to-air intercooler (the air enters via the enhanced roof scoop) before being fed into the engine itself. All charge air ducting has been kept as short as possible with large diameter pipes to minimise restriction and maximise throttle response and efficiency. Four high capacity injectors and an uprated fuel pump add additional fuel under hard acceleration or continuous high speed driving.

A sports-type clutch plate and heavy duty clutch cover transfer the engine power and torque to the lightweight C64 six-speed gearbox (with an aluminium casing) – with the same perfectly spaced ratios as the Exige S. A Torsen type limited slip differential is fitted as standard, with a plate type limited slip differential available as an option. Keen to pass on lessons learned on the track with the Exige GT3 racing programme, Lotus Sport has contributed another important technology – launch control combined with variable traction control. This combo has already made its production debut with the track-oriented Lotus 2-Eleven.

From the driver’s seat the launch control allows you to determine the number of revs you wish to use during a standing start. Having programmed that limit, you then hold your foot down hard on the throttle and sidestep the clutch at departure from the line time. The clutch damper cushions the severity of the clutch / transmission engagement to minimise the stresses to the drivetrain (noting that abusive/ continuous standing start applications will destroy the drivetrain components). The launch control also keeps wheelspin at bay until 6 mph, after which the traction control assumes its duties.

As with launch control, you can control the amount of traction control you require from the driver’s seats, altering it on the move to suit the characteristics of particular corners. The amount of traction control can be varied in over 30 increments from an optimum 7 percent tyre slip to completely off. The message display in the new instrument pack displays what degree of traction control you have currently dialled in.

An Accusump (engine oil accumulator unit) is included in the whole package as an oil reservoir back-up for extreme track use ensuring that, under those conditions, the engine oil pressure remains constant.

More than just new dials

The new instrument pack fitted to the whole of the MY2008 Exige and Elise range is also carried over to the Sport Exige Cup 260. It is more than just a fresh pair of stylishly back-lit dials. It also features a high-definition LCD message panel that can display a scrolling text message with vehicle systems information.

The new instrument pack always displays the fuel gauge, engine temperature and odometer, however you can select to display the time, trip distance or a digital read-out of your speed in the opposite calibration to that of your speedometer dial – if your dial is in mph, the readout is in km/h and vice-versa.

Warning symbols are ‘secret until lit’, keeping the instrumentation free from visual clutter and distraction until absolutely necessary. New gearchange ‘shift’ lights similarly remain hidden until required. There are three shift up lights, cumulatively lighting when the driver is getting closer to the rev limiter and when all three are illuminated, they flash to indicate that you’re almost on the rev limiter so time to change up a gear!

A “key” issue

In response to forthcoming legislation, the Exige Cup 260 has a new “Thatcham approved” alarm/immobiliser system. This, in turn, has enabled the new Lotus design of key that incorporates the controls for the alarm/immobiliser and central locking functions. This upmarket key fob features three buttons, the one which locks the doors and sets the alarm/immobiliser is stylishly crowned with the famous Lotus roundel. The second button unlocks the doors and de-actives the alarm/immobiliser, and the final button is a panic button.

Roof Scoop

The Lotus Sport Exige Cup 260 retains the full length roof scoop from the outgoing Sport Exige Cup 255, which improves the intake ambient air flow rate, so allowing the Exige Cup 260 to gain a higher charge density in the cylinders.

Wheels and Tyres

16-spoke cast wheels are shod with Lotus specific LTS compound Yokohama A048R tyres to maximise grip and achieve the ride and handling targets set by Lotus.

Brakes

The brake system includes large diameter 308 mm 2-piece aluminium belled cast iron cross- drilled and ventilated front discs and 282 mm cross-drilled and ventilated discs at the rear, upgraded Pagid RS14 sports brake pads set into the brake calipers (AP Racing two piece radially mounted, 4 piston at the front and Brembo sliding at the rear), high grade silicone brake fluid and stainless steel braided brake hoses – all linked to the proven Lotus track tuned servo-assisted four-channel ABS system that enhances braking performance and minimizes stopping distance without taking over from the skill of the driver.

Suspension

Adjustable dampers and a stiffened and adjustable front anti-roll bar allows customers to tailor the handling characteristics of the car to their own requirements. As the Lotus Sport Exige Cup 260 cars are equipped for track use, a double shear track control arm brace is provided to cope with the expected kerb abuse during racing or hard track day driving.

Safety Equipment

Lotus Sport Exige Cup 260 cars have the safety equipment expected of a race car, with sports seats, 3-point “Webb Lock” harnesses (4-point driver and passenger seat belt harnesses are provided for track use only). The 6-point roll cage is FIA approved and is provided with the vehicle as a no-cost option for dealer fit after delivery. Completing the additional safety equipment is An electronic ignition kill switch with cockpit and external activation and a plumbed electrically activated fire extinguisher system, again with cockpit and external panic switches.

Specification

The standard specification Lotus Sport Exige Cup 260 is road legal within the European Union, and can be registered for road use. The vehicle is supplied with a separate FIA approved 6- point roll cage and 4-point harnesses. These are for track use only and can be installed by an authorized Lotus dealer at the request of the customer. Other track options are available from Lotus Sport that can be fitted during production. Vehicles fitted with these parts cannot be road registered.

Options (all subject to local taxation rates)

• FIA approved 70 litre fuel cell (track use only)
• Lotus Sport limited slip differential (plate type)
• Air conditioning
• Metallic paint
• Lifestyle paint
• Race battery and holder

Other more hardcore track options are available – prices on application (ie ‘Level Two’ exhaust with de-cat pipe, dog gearbox, Recaro/Lotus Sport driver’s seat with 6-point harness etc).

Stuttgart. Mit einer auf 420 PS gesteigerten Leistung startet der neue Porsche 911 GT3 Cup in die Motorsportsaison 2008. Eingesetzt wird er im Porsche-Mobil1-Supercup, dem schnellsten internationalen Markenpokal der Welt, sowie weltweit in den nationalen Porsche Carrera Cups und den GT3 Cup Challenges. 265 Exemplare des in Weissach entwickelten seriennahen Rennwagens werden auf der Produktionslinie in Stuttgart-Zuffenhausen gebaut. Das ist ein neuer Rekord.

Die auffälligste Veränderung im Vergleich zum Vorjahresmodell ist das neue Heckteil, das dem Design des Serienfahrzeuges entspricht. Die Lüftungsschlitze sorgen für eine bessere Wärmeableitung im Heckbereich.

Der in Weissach entwickelte 3,6-Liter-Sechszylinder-Boxermotor basiert ebenfalls auf dem straßenzugelassenen GT3 und leistet 420 PS; beim Vorgänger waren es 20 PS weniger. Das sequentielle Sechsgang-Getriebe mit Zugkraftunterbrechung ermöglicht das Hochschalten bei Vollgas ohne Kupplungsbetätigung. Das Getriebe wurde optimiert und die Übersetzung an die Motorcharakteristik angepasst. Das Einsatzgewicht von 1.150 Kilogramm entspricht einem Leistungsgewicht von 2,7 Kilogramm pro PS.

Die 26 für den Porsche-Mobil1-Supercup gebauten Exemplare des 911 GT3 Cup sind exklusiv mit einer speziellen Abgasanlage mit einem nochmals markanteren, an das Formel 1-Umfeld angepassten Klangbild sowie der Porsche-Keramik-Verbundbremse PCCB (Porsche Ceramic Composite Brake) ausgestattet. Im Vergleich zu konventionellen Bremsscheiben verringert PCCB die ungefederten Massen um 20 Kilogramm und setzt neue Maßstäbe in Sachen Ansprechverhalten, Fadingstabilität und Haltbarkeit. Die weltweit im Carrera Cup eingesetzten Rennwagen verfügen über eine modifizierte Abgasanlage und Stahlbremsscheiben.

Für die Feinabstimmung und das Einfahren der 911 GT3 Cup zeichnet die Rennabteilung in Weissach verantwortlich. Die Auslieferung erfolgt je nach Land von Weissach aus. Während die Fahrzeuge für den Carrera Cup Neuseeland bereits verschickt wurden, ist die Auslieferung der für den Porsche-Mobil1-Supercup und den Carrera Cup Deutschland bestimmten Rennwagen für Anfang März 2008 vorgesehen.
