Stronger, wider, faster – the new Porsche 911 GT3 Cup car is the latest-edition of the world’s best-selling and most successful production-based race car of more than 1,400 units. It will be introduced at the Frankfurt Motor Show September 17-27, 2009, along side the previously-announced 2010 Porsche 911 Turbo and 911 GT3 RS.
For the first time, the race car is based on the street-legal 2010 GT3 RS version. However, in keeping with tradition, it continues to be assembled on the same production line as all road-going Porsche 911 vehicles in Stuttgart-Zuffenhausen.
Like the flat-six “Boxer” engine in the new GT3 RS, displacement is increased by 0.2 liters over the former model to 3.8 liters and produces 30 more horsepower – 450 hp with a maximum RPM of 8,500. Additionally, it comes with a standard, sequential six-speed manual gearbox and weighs 2,646 lbs (1,200 kg).
Also like the 911 GT3 RS, the Porsche 911 GT3 Cup car features the 1.73-inch wider body of the current 911 Carrera 4S, providing sufficient space for larger wheels. Wider front wheel arches allow for three-piece light-alloy rims measuring 9.5 J x 18 (previously 9 J x 18) utilizing 24/64-18 Michelin racing tires. The three-piece light-alloy wheels on the rear axle are up by one inch in width, now measuring 12 J x 18 with 27/68-18 tires.
The Porsche 911 GT3 Cup is clearly recognizable at first sight through the special design of the front end. The striking daytime driving lights come straight from the current generation 911. Another carryover from the road-going 911 GT3 RS are the front body panels – as they prove aerodynamically-efficient for racing duty. The front spoiler lip is more than 0.5-inches lower to provide significantly more downforce on the front axle.
Downforce on the rear axle is also increased by the by virtue of a rear wing that is over 9-inches wider than the street version, 66.9 inches vs. 57.5 inches respectively. The rear air dam, with its air vent openings as well as the rear LED lights, also come straight from the road model.
Additional Unibal joints are featured on the track control arms and the front and rear anti-roll bars are now adjustable to seven different positions, allowing for an even more precise set-up of the car to best match each prospective race track.
The cockpit of the new Porsche 911 GT3 Cup caters even more to the specific needs of the driver. An additional vent in the upper part of the front lid, for example, provides the driver with a better supply of fresh air. The controls for the Info Display are now positioned directly on the steering wheel housing. And in addition to fore-and-aft adjustment, the steering wheel may now also be adjusted for height as on the regular production car.
Since the current era of sports car racing in the U.S started in 1999, Porsche 911 race cars have over 130 class victories, more than any other manufacturer. In addition, Porsche has won seven of ten GT2 manufacturers’ championships and eight of ten drivers’ championships in the American Le Mans Series. In addition, 911 race cars have won seven of nine GT championships in the Grand-Am Road Racing series, including an overall victory at the Rolex 24 at Daytona.
