Porsche introduces the latest edition of its 911 GT3 Cup race car which will exclusively compete in the one-make Porsche Mobil 1 Supercup in 2013. The 991-based race car which is built in the same assembly line as the current 911 road car also previews the future production model of the 911 GT3.
The new Porsche 911 GT3 Cup is powered by a 3.8-liter six-cylinder flat engine and generates 460 hp (338 kW) at 7,500 RPM, surpassing the predecessor by 10 hp. A six-speed dog-type gearbox developed by Porsche Motorsport, which is operated via shift paddles at the steering wheel for the first time in a Porsche brand trophy race car, transmits the power to the rear axle. The single piece race wheels with center mount were also newly designed by Porsche Motorsport. The width of the Michelin race slicks was increased by two centimeters at the front and by ten millimeters at the rear axle.
A newly developed race braking system further improves the excellent endurance qualities compared to its successful predecessor. The 380 millimeter slotted and inner-vented steel brake rotors at the front axle are decelerated by six-piston aluminum fixed calipers while the rear axle features a four-piston version.
During the development of the new car, a particular emphasis was put on the driver safety. A newly designed safety cage protects the pilot in case of a roll or a collision as does a newly developed race seat which is distinctively shaped around the head and shoulders and can be adjusted individually with the help of padding. A rescue hatch in the roof provides easy access for primary medical attention and for the extraction of the driver.
"The new 911 GT3 Cup is much easier to drive at the limit," says Porsche works driver Timo Bernhard, who was significantly involved in the development of the new vehicle. "The car is excellently balanced. The new axle geometry is enormously positive for the handling. In addition, the new Cup 911 is great fun to drive."
The new 911 GT3 Cup will be run exclusively in the Porsche Mobil 1 Supercup in 2013. The rest of the Porsche makes cups and challenge cups around the world, including the IMSA GT3 Cup Challenge by Yokohama and the IMSA GT3 Cup Challenge Canada by Michelin, will compete in the current 911 GT3 Cup race car for 2013 and is set to switch to the new car in 2014.
