(from Porsche Press Release)
Lighter and more powerful than the 911 Turbo on which it is based, the
Porsche 911 GT2 is the ultimate Porsche model for 2003. With 456
horsepower (SAE), the GT2 can accelerate from a standing start to 62 mph
(100 km/h) in about four seconds and can achieve a top speed of 195 mph
(315 km/h) on the test track.
The biggest weight saving over the 911
Turbo is achieved by making the GT2 a rear-wheel drive sports car (the
911 Turbo is all-wheel drive). Other weight-saving measures include
fitting sport seats in front and deleting the rear seats and replacing
the spare tire with a tire repair kit which includes a bottle of sealing
foam, an air compressor and a pressure gauge.
The 911 GT2 is the first Porsche to be
fitted as standard with the Porsche Ceramic Composite Brake (PCCB®). The
ceramic composite discs weigh 50-percent less than comparable metal
discs, reducing unsprung weight by a significant 36.6 lb. (16.6 kg) and
thus enhancing suspension response.
In addition to weighing more than 200
pounds less than the 911 Turbo, the 911 GT2 has a more powerful version
of Porsche’s 3.6-liter twin-turbo six-cylinder “boxer” engine. For the
911 Turbo, the twin turbochargers boost airflow into the engine to 11.76
psi. But for the 911 GT2, those turbochargers spin 14.5 psi into the
engine. The GT2 engine produces 456 horsepower at 5,700 rpm and
sustained 457 lb.-ft of peak torque from 3,500-4,500 rpm.
The only transmission available is a
modified version of the 911 Turbo six-speed manual. A special asymmetric
limited-slip differential helps stabilize the car in curves under load
Compared to the 911 Turbo, redesigned air
intake scoops provide additional cooling air. Porsche also refined the
GT2’s aerodynamic characteristics to produce greater downforce. A
one-piece fixed-design rear wing replaces the two-piece
automatic-deploying spoiler of the 911 Turbo and allows six degrees
adjustment for racetrack driving.
The GT2 also benefits from chassis
modifications that come directly from Porsche’s road racing experience.
Suspension modifications include racing springs that lower the center of
gravity by 0.78-inch (20 mm), adjustable anti-roll bars and a wide range
of suspension adjustment to accommodate racing tires. The front alloy
wheels measure 18 x 8.5-inch and mount 235/40 ZR18 tires. The rear alloy
wheels measure 18 x 12-inch and mount 315/30 ZR18 tires.
The GT2 retains all current Porsche
safety technology, including dual front airbags plus the Porsche Side
Impact Protection System, which includes boron-steel door reinforcement
beams, energy-absorbing door panels and door-mounted side airbags. The
30-liter capacity sidebags provide additional protection for the chest,
head, and pelvis.
Although the 911 GT2 deletes some of the
luxury content from the 911 Turbo, its standard equipment includes power
windows and an anti-theft system with transponder key, immobilizer,
alarm plus central locking with remote entry. The GT2 has a standard
digital radio with in-dash CD player. Automatic climate control and
cruise control and natural leather trim are available as options.
