The Porsche 997 GT3 Cup is entering the 2006 Porsche Supercup motorsport season with engine output increased to 400 hp. The car will be raced in the Porsche Mobil1 Supercup, the world’s fastest international brand trophy, and worldwide in national Porsche Carrera Cups ,GT3 Cup Challenges and most important national and international championships . 265 units of this production-based racing car developed in Weissach will be built on Porsche’s production line in Stuttgart-Zuffenhausen.
The 911 GT3 Cup (997) was developed based on the current 911 generation, which has been gradually and successfully established in the market since the end of 2004.
The 3.6-litre six-cylinder boxer engine developed in Weissach is also based on the street-legal GT3 and develops maximum output of 400 hp, 20 horsepower more than on the previous model. The sequential six-speed transmission with interruption of engine power enables the driver to shift up under full throttle without disengaging the clutch. The transmission itself has been optimised and the gear ratios adjusted to the characteristics of the engine. Weighing 1,150 kg in race trim, the new 911 GT3 Cup has a power-to-weight ratio of 2.7 kg per horsepower.

26 units of the 911 GT3 Cup built for the Porsche Mobil 1 Supercup feature a special exhaust system with an even more striking sound pattern reminiscent of the Formula 1 racing scene as well as PCCB Porsche Ceramic Composite Brakes as exclusive highlights. Compared with conventional brake discs, PCCB reduces unsprung masses by 20 kg and sets new standards in terms of responsiveness, resistance to fading, and a long service life. The racing cars entered worldwide in the Carrera Cup feature a modified exhaust system and steel brake discs.
