World's Most Successful Production-based Race Car Moves to Porsche 911
(type 991) in 2013 for Porsche Mobil 1 Supercup; More Horsepower,
Paddle Shift Highlight Improvements

Stuttgart/Atlanta December 8 -- The Porsche 911 GT3 Cup is the most
successful race car in the world. Since 1998, 2,395 units of the
near-street-stock race vehicle for customer sport have been produced.
The new edition of the 911 GT3 Cup is the motorsports version of the
future showroom model 911 GT3 (yet to be introduced) and as such is
the first race car that is based on the seventh generation of the
sports car icon (Porsche 911 type 991) from Zuffenhausen.

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 racer for 2013, switching to the
new car in 2014. The new car for one-make racing made its debut on the
occasion of the end of motorsport season "Night of
Champions" celebration at the R&D Centre in Weissach.

The new Porsche 911 GT3 Cup is powered by a 3.8-litre six-cylinder
flat engine. It generates 460 hp (338 kW) at 7,500 revs, 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 centimetres to
27 centimetres at the front and by ten millimetres at the rear axle to
now measure 31 centimetres.

A newly developed race braking system further improves the excellent
endurance qualities compared to its successful predecessor. The 380
millimetre slotted and inner-vented steel brake rotors at the front
axle are decelerated by six-piston aluminium fixed callipers. 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."

Like its predecessor the new Porsche 911 GT3 Cup is produced in
Stuttgart-Zuffenhausen on the same assembly line as the street-legal
models. At the Motorsport Center in Weissach, it receives a general
set-up for the race track and is tested by a professional race driver
before delivery to the customers. The starting price for the vehicle,
which is available exclusively in white, is 181,200 Euro plus the
country-specific taxes.
