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 new 911 GT3 Cup has a power-to-weight ratio of 2.7 kg per horsepower.
