(from Porsche Press Release) The
911 GT3 represents the most powerful non-turbocharged Porsche ever
offered for street use in the United States and Canada.
Based on the previous 911 GT3 that was
not available in North America, the 2004 Porsche® 911 GT3 features a
3.6-liter, flat- six cylinder engine producing 380 horsepower (SAE) and
285 pound-feet of torque. With a power output of an impressive 105
horsepower per liter, the engine propels the 911 GT3 from 0 to 60 mph in
4.3 seconds, from 0 to 100 mph in 9.4 seconds, and to a top track speed
of 190 mph. To handle this increased performance, the 911 GT3’s
transmission is fitted with transmission oil cooling and injection oil
lubrication and has undergone some additional reinforcements.
The most striking visual feature of the
new 911 GT3 is its unique rear wing that is largely responsible for
excellent directional stability at high speeds and increased downforce
for fast cornering. Combining a redesigned front apron, the GT3 achieves
an outstanding drag coefficient (Cd=0.30) for a car in its class.
The GT3’s handling is further enhanced by
a sports suspension, wider and lighter wheels, and wider tires. Front
wheels are 8.5 inches wide fitted with 235/40 ZR 18 tires, and rear
wheels are 11 inches wide with 295/30 ZR 18 tires.
Brakes on the GT3 have been improved as
well. Front brakes now feature six-piston, rather than the previous
four-piston monobloc brake calipers and larger discs fitted with
Porsche-patented cooling ducts. The ABS brake system was also modified.
The new system (ABS 5.7) has a faster and more sensitive control
response. It is also lightweight and provides greater stability for ABS
braking. Porsche Ceramic Composite Brake (PCCB®) discs, standard on the
911 GT2, can be fitted on request. |
