Porsche 911 GT2

The Porsche® 911® GT2, the ultimate Porsche model for 2002, is 10-percent more powerful and seven-percent lighter than the 911 Turbo on which it is based. The biggest weight savings over the 911 Turbo comes from making the GT2 rear-wheel drive (the 911 Turbo is all-wheel drive). Other weight-saving measures include fitting sport seats in front and deleting the rear seats. In place of a spare tire, there is a tire repair kit. Chassis modifications come directly from Porsche’s road racing experience. The GT2 can accelerate from zero-to-62 mph (zero-to-100 km/h) in about four seconds and can achieve a top track speed of 195 mph (315 km/h).

A modified version of the 3.6-liter twin-turbo six-cylinder “boxer” engine from the 911 Turbo allows an increase in maximum turbo boost pressure to 14.5 psi, compared to 11.76 psi for the 911 Turbo. The GT2 engine produces 456 horsepower at 5,700 rpm and sustains 457 lb.-ft. (620 Nm) 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 changes.

Compared to the 911 Turbo, redesigned air intake scoops provide additional cooling air. Porsche refined the 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 1-6 degrees adjustment for racetrack driving. 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 911 GT2 is the first Porsche to be fitted as standard with the Porsche Ceramic Composite Brake (PCCBTM). 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.
