Porsche has revealed plans to introduce a new ultra high performance GT3 version of its 911 Carrera coupe to world markets in spring 2003.  The new model will be the most powerful non-turbocharged Porsche ever offered for street use.

Based on the previous 911 GT2, the GT3 version features a 3.6-litre, flat-six cylinder engine producing 380 horsepower and 285 pound-feet of torque.

With a power output of an impressive 105 horsepower per litre, 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.

With a redesigned front apron, the GT3 achieves an outstanding drag coefficient (0.30Cd) for a car in its class.

The GT3's handling is further enhanced by a sports suspension, wider and lighter wheels, and wider tyres.

Front wheels are 8-1/2 inches wide fitted with 235/40 ZR 18 tyres, and rear wheels are 11 inches wide with 295/30 ZR 18 tyres.

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 are fitted with Porsche-patented cooling ducts. The lightened ABS brake system is also modified with a faster and more sensitive control response.

Porsche Ceramic Composite Brake (PCCB) discs, standard on the 911 GT2, can be fitted on request.
