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.
