Porsche 911 GT3 Cup
The Newbridge Motorsport-run Porsche GT3 Cup was driven to third in the 2014 Dunlop Endurance Championship Drivers’ standings by Guillaume Gruchet.
No fewer than 265 units of this production-based racing car, developed in Weissach, have been built on Porsche’s production line in Stuttgart-Zuffenhausen, marking a new record for a car of this specification.
The most significant modification compared with previous models 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 churns out 420bhp – 20 horsepower more than 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.
