911 GT3 Cup

The rear of the world’s most-produced GT racing car now houses a 4-litre, six-cylinder flat engine for even more drive. Thanks to thoroughbred motorsport technology, the compact engine with direct fuel injection delivers peak performance of 357 kW (485 hp). A range of innovative details also improve efficiency in addition to engine performance, ensuring even better durability of the naturally aspirated engine in racing mode and reduced maintenance costs.

To a large extent, the 3.6-litre boxer engine is identical to the power unit used in the Porsche Mobil1 Supercup and the international Carrera Cup championships. Power output has increased by 20 horsepower to now 440 hp (324 kW) at 8,000 rpm. Maximum torque is up by ten Nm to 430 at 7,250 revs per minute. The power increase results from optimised engine electronics and a modified exhaust system. In contrast to the GT3 Cup, the body of the Cup S is not based on the road-going GT3 but on the GT3 RS.

The Porsche 997 GT3 Cup was a series of race cars created by Porsche to enter the Fédération Internationale de l’Automobile (FIA) Group GT3 racing class. Replacing the 996 GT3 Cup, the 997 Cup's 3.6 litre engine is rated at 294 kW (400 PS; 394 hp) and was mated to a six-speed sequential transmission. In 2009, the GT3 Cup received several 997.2 updates including a new 3.8 litre engine with an output of 331 kW (450 PS; 444 hp).

The 996 GT3 Cup served as the basis for the 996 GT3 road car, featuring a 3.6 litre engine with 355 hp. For the 1999 season the engine output was increased to 365 hp. For the 2001 season the GT3 Cup received modified aerodynamics including an enlarged rear wing and improved cooling. For 2002, the GT3 Cup received several changes, adopting facelift 996.2 features such as Turbo-style headlights. The new body significantly improves aerodynamics and cooling. Engine output was increased to 380 hp. For 20003 onward, the power was hiked once again, with the engine now pumping out 385 bhp @ 7250 rpm and of torque 288 ft lbs @ 6500 rpm.
