The Porsche 911 GT3 Cup is the most successful race car in the world. Since 1998, 2,395 units of the near standard vehicle for customer racing have been produced. Unveiled for the first time on Saturday night at the Porsche Motorsport ‘Night of Champions’ celebration at Weissach, the new ‘Type 991’ edition of the 911 GT3 Cup is the motorsport version of the forthcoming 911 GT3 road car. It is also the first race car based on the seventh generation of the sports car icon from Stuttgart; the 911 GT3 Cup will run exclusively in the Porsche Mobil 1 Supercup in 2013.
The new car is powered by a 3.8-litre six-cylinder flat-six engine. It develops 460 hp (338 kW) at 7,500 revs, surpassing the predecessor by 10 hp. A six-speed ‘dog-type’ gearbox developed by Porsche Motorsport transmits the power to the rear axle and, for the first time in a Porsche Cup race car, is operated via shift paddles on the steering wheel.
The single-piece race wheels with centre mount are also newly-designed by Porsche Motorsport. The width of the Michelin race slicks has increased by two centimetres to 27 cm at the front, and by one centimetre at the rear axle to now measure 31 cm.
A newly-developed braking system further improves the excellent endurance qualities compared to its successful predecessor. The 380 mm diameter slotted and inner-vented steel brake discs on the front axle are accompanied by aluminium six-piston fixed callipers. The rear axle features a four-piston version.
During the development of the new car a particular emphasis was put on driver safety. A new safety cage protects the driver in case of a roll or a collision, and this is further aided by a newly-developed race seat which is distinctively shaped around the head and shoulders and can be adjusted individually with the help of padding. Furthermore, a rescue hatch in the roof provides easy access for primary medical attention and for the extrication of the driver.
“The new 911 GT3 Cup is much easier to drive at the limit,” said Porsche factory race driver Timo Bernhard, who was closely involved in the development of the new racer. “The car is excellently balanced. The new axle geometry is enormously positive for the handling. Apart from that, the new Cup 911 is great fun to drive!”
Like its predecessor, the new Porsche 911 GT3 Cup is produced in Stuttgart-Zuffenhausen on the same assembly line as the road cars. At the Motorsport Centre in Weissach, it receives a general set-up for the circuit and is tested by a professional race driver before delivery to the customers. The basic price for the vehicle, which is available exclusively in white, is 181,200 Euro plus the country-specific value added tax.
