(from Porsche Press Release) 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.
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, immobiliser,
alarm plus central locking with remote entry. The GT2 substitutes a CD
stereo system for the Bose digital sound system used in the 2002 911
Turbo. Automatic climate control and cruise control and natural leather
trim are available as options.
