WEISSACH, Germany - The Porsche 911 GT3 Cup is the most successful race car in the world. Since 1998, more than 2300 of the near-standard car for customer racing have been produced.The new Type 991 edition is the motorsport version of the forthcoming 911 GT3 road car and was unveiled for the first time on Dec 8/2012 at a Porsche Motorsport “Night of Champions” celebration.SPORTS-CAR ICONIt 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.Image galleryThe new car is powered by a 3.8-litre, six-cylinder, flat-six engine. It develops 338kW at 7500rpm, surpassing its predecessor by 7kW. A six-speed gearbox developed by Porsche Motorsport transmits the power to the rear axle and, for the first time in a Porsche Cup racer, is operated by shift paddles on the steering wheel.The single-piece race wheels with centre mount are also new to Porsche Motorsport. The width of the Michelin race slicks has increased by two centimetres to 27cm at the front and by one centimetre at the rear axle to now measure 31cm.A new braking system further improves the endurance qualities compared to its predecessor. The 380mm diameter slotted and inner-vented front steel brake discs are accompanied by aluminium six-piston fixed callipers.The rear axle has a four-piston version.SAFETY FIRSTDuring the development of the new car particular emphasis was put on the drivers' safety. A new crash cage sits around a race seat which is distinctively shaped around the head and shoulders and can be adjusted individually with padding.A rescue hatch in the roof provides easy access for primary medical attention and to lift out the driver.Porsche factory race driver Timo Bernhard, who was closely involved in the development of the new racer, said: “The new 911 GT3 Cup is much easier to drive at the limit. The car is excellently balanced. The new axle geometry is enormously positive for the handling. On top of that, the new Cup 911 is great fun to drive.”Like its predecessor, it 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 customers.The basic price for the vehicle, available only in white, is the equivalent of about R2.03-million, plus country-specific VAT and other duties.
