The 2008 Porsche 911 GT3 Cup is entering the 2008 motorsport season with engine output increased to 420 bhp. The car will be raced in the Porsche Mobil1 Supercup, the world’s fastest international brand trophy, and worldwide in national Porsche Carrera Cups and GT3 Cup Challenges. 265 units of this production-based racing car developed in Weissach will be built on Porsche’s production line in Stuttgart-Zuffenhausen, marking a new record for a car of this category.
The most significant modification compared with last year’s model is the new rear end following the design of the production model. Air venting slits ensure better dissipation of heat at the rear. The 3.6-litre six-cylinder boxer engine developed in Weissach is also based on the street-legal GT3 and develops maximum output of 420 bhp, 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 2008 Porsche 911 GT3 Cup has a power-to-weight ratio of 2.7 kg per horsepower.
