The new 991-series Porsche 911 GT3 Cup racer has been unveiled at the iconic sports car maker's research and development centre in Weissach, Germany, ahead of its motorsport debut in next year's Porsche Mobil 1 Supercup in 2013.
The highly anticipated track-bound 911 GT3 Cup racecar is based on the yet-to-be-revealed Porsche 911 GT3 road car that CarAdvice’s spy photographers snapped on the street in May and at the Nurburgring in August ahead of its anticipated 2013 launch.
Producing 7kW more power than its predecessor, the 2013 Porsche 911 GT3 Cup teams a naturally aspirated 338kW 3.8-litre six-cylinder engine with a new Porsche Motorsport-developed six-speed dog-type transmission, which – for the first time in a Porsche brand trophy racecar – is operated via steering wheel-mounted paddle shifters.
The new gearbox sends drive to the rear axle, which now features 310mm-wide Michelin racing tyres (+10mm) and slotted, inner-vented steel brake rotors with four-piston aluminium calipers. The front scores 270mm-wide tyres (+20mm) and 380mm brakes with six-piston calipers. Newly designed single-piece race wheels with centre mount fill the space between at all four corners.
Safety has also been a focus of the new-generation 911 GT3 Cup, with Porsche equipping the 2013 model with a revised safety cage offering added protection for the driver in a rollover or collision, a new race seat with extra head and neck support, and a rescue hatch in the roof designed to provide easy access for medical staff.
Porsche works driver Timo Bernhard says the 2013 Porsche 911 GT3 Cup is “much easier to drive at the limit” than the car it replaces.
“The car is excellently balanced,” Bernhard said. “The new axle geometry is enormously positive for the handling.
“Apart from that the new Cup 911 is great fun to drive."
The new Porsche 911 GT3 Cup will be produced in Stuttgart-Zuffenhausen on the same assembly line as the 911 road cars. Available exclusively in white, the 911 GT3 Cup is priced from 181,200 euros ($223,400) plus local taxes.
