2004 Porsche 911 GT3

(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.
