New 2011 911GT3 Cup car unveiled for Carrera Cup GB

The 911GT3 Cup car that will be raced in the 2011 Porsche Carrera Cup GB was unveiled to teams and drivers at Oulton Park yesterday (Friday 4 June).

The stunning new car, already in use in the Porsche Mobil 1 Supercup and several Carrera Cups around the world, will be introduced into the Carrera Cup GB car for 2011. Up to 28 new cars will be produced for the 2011 Carrera Cup GB and the first deposits were taken within minutes of the car being unveiled.

"This car is more of a step change than an evolution," said Geoff Turral, general manager Porsche Cars GB, when unveiling the latest car. An increase in engine size from 3600cc to 3800cc has boosted power output to 450bhp, while a wider bodyshell is drawn from the GT3RS. Notable among a raft of detail changes is the rear wing, which is both wider and higher to increase down force. "The new car is quite technically different to the existing car," said Turral.

Reigning Carrera Cup GB champion and current Supercup racer Tim Bridgman spoke about the driving experience in the new car. "You can feel the extra power straightaway and it's a move advanced racing car. The adjustments do more to the car and it is incredibly sensitive; it gives more scope to the drivers and engineers."

The car will next be on display at the Goodwood Festival of Speed (2-4 July) and will then be one of the cars to be raced by Carrera Cup GB Scholars Euan Hankey and Michael Meadows in the Porsche Mobil 1 Supercup race at Silverstone on 11 July.

"We may have more demand than we can supply," said Turral. "We are keen to create a strong market for the current cars so that our existing teams and drivers can step up to the new car." Turral also reported strong interest from new teams looking to join the Carrera Cup GB grid for 2011.

The new Porsche GT3 Cup Challenge, run by the Porsche Club GB, is expected to absorb a number of the current cars, while the creation of new GT3 Cup Challenges in several European markets for 2011 will further increase demand for the current cars.

The latest development of the superb 911GT3 Cup car is stronger, wider and faster than its predecessor and is the first GT3 Cup to be based on the 911 GT3 RS. The new car builds further on the runaway success of the previous model, which was the best-selling racing car of all time with more than 1400 cars produced.

The new car has been created for the Porsche Supercup and the ever-growing number of Carrera Cups and GT3 Cup Challenges around the world. It is powered by the same 3800cc engine as the 911 GT3 RS, delivering 450bhp at 8500rpm; an increase of 30bhp over the previous model.

The new model was unveiled for the 2010 season and was immediately introduced into the Porsche Mobil 1 Supercup, the Carrera Cups in Germany, Asia, Japan and Italy as well as the GT3 Cup Challenges in the USA and the Middle East.

This is the first GT3 Cup to feature the 44-millimetre wider body at the rear, providing space for even larger wheels. Wider wheel arches at the front also allow the use of new front wheels.

On-track, the new car offers more rear downforce with the rear wing being both wider and higher. Power is delivered through a sequential six-speed manual gearbox and the complete package weighs in at 1200kg.

Now, for 2011, the new car is coming to the Porsche Carrera Cup GB and it is surely going to be hugely popular with drivers and fans alike.

Stronger, wider, faster - the new version of the Porsche 911 GT3 Cup offers its many customers the world over even greater value than ever before. The successor to the best-selling racing car of all time built in a production series of more than 1,400 units is based for the first time on the 911 GT3 RS, with the weight of the racing model reduced significantly versus the lightweight road-going version.

This is the first GT3 Cup to feature the 44-millimetre (1.73") wider body at the rear, providing sufficient space for even larger wheels. Wider wheel arches also at the front clearly show that the front wheels are likewise new. Engine capacity is up by 0.2 litres over the former model, engine output is 30 bhp more than before.

The most important facts and figures:

  • - single-seated, near-standard race vehicle
    - racing version of the 911 GT3 RS
    - 3.8-litre six-cylinder horizontally-opposed power unit developing 450 bhp (331 kW)
    - sequential six-speed manual gearbox
    - weight 1,200 kg (2,646 lb)

The new GT3 Cup is clearly recognisable at very first sight through the special looks and design of the front end. The striking daytime driving lights come straight from the current generation of the 911, the front body panels are the same as on the 911 GT3 RS. The front spoiler lip is however 15 millimetres or almost 0.6" lower to provide significantly more downforce on the front axle. Downforce on the rear axle is also increased by the rear wing extended in width from 1.46 to 1.70 metres (57.5 to 66.9") and fitted higher up as a feature carried over from the even faster 911 GT3 Cup S in international FIA GT3 racing. The rear air dam with its striking air vent openings as well as the rear lights in LED technology, in turn, come straight from the road model.

The power unit featured in the new 911 GT3 Cup is largely identical to the production engine in the 911 GT3 RS - same output of 450 bhp and same maximum engine speed of 8,500 rpm. Capacity of the Cup engine, however, is up from 3.6 litres on the former model to 3.8 litres on the new car, helping to increase engine power by 30 bhp.

A racing exhaust system with a fully controlled catalytic converter helps to reduce harmful emissions to a minimum. As an exclusive feature in the Porsche Mobil 1 Supercup held on the occasion of the FIA Formula 1 World Championship races, the new 911 GT3 Cup comes with a modified, special exhaust system offering an even more dynamic and muscular sound. Another feature exclusive to the Supercup version is PCCB Porsche Ceramic Composite Brakes also available on Porsche's road models. Compared with the composite cast brake discs featured on the Carrera Cup cars, this reduces the weight of the car by approximately 20 kg or 44 lb.

The wheel arches wider at the front and the flared wheel arches at the rear provide ample space for even wider wheels. Hence, the front axle comes with three-piece light-alloy rims measuring 9.5 J x 18 (previously 9 J x 18 ) and running on 24/64-18 Michelin racing tyres. The three-piece light-alloy rims on the rear axle are up by one inch in width, now measuring 12 J x 18 and running on 27/68-18 tyres.

Additional Unibal joints are featured on the track control arms and the sword-shaped anti-roll bars front and rear are now adjustable to seven different positions on both sides, allowing an even more precise set-up of the car in accordance with the respective race track.

The cockpit of the new 911 GT3 Cup caters even more than before for the specific needs of the driver. An additional vent in the upper part of the front lid, for example, provides the driver with an even better supply of fresh air. The controls for the Info Display are now positioned directly on the steering wheel housing a total of six switches. And in addition to fore-and-aft adjustment, the steering wheel may now also be adjusted for height as on the regular production car.

The new Porsche 911 GT3 Cup available exclusively in Carrara White will be delivered to customers as of the end of October. In the upcoming season it will be raced in no less than seven cup trophies - not only in the Porsche Mobil 1 Supercup on the occasion of Formula 1 races, but also in the Porsche Carrera Cups in Germany, Asia, Japan, and Italy, as well as the GT3 Cup Challenges in the USA and the Middle East.
