Porsche 911 GT3 Cup - 2007



The current Porsche 911 GT3 Cup made its debut exclusively in the 2005 Porsche Supercup - and immediately took off on a success streak, setting new records on all circuits the fastest international makes cup of the world visited. From 2006 Porsche delivered the GT3 Cup successively to all one-make racing series around the globe. For 2007 the factory at Zuffenhausen and the motorsport centre Weissach produced the record number of 233 units of the near-standard racer.


Only in the Porsche Mobil1 Supercup the GT3 Cup features the Porsche Ceramic Composite Brake PCCB. In the Carrera Cups and GT3 Cup Challenges the cars are fitted with steel brake discs. PCCB reduces unsprung rotating masses and the overall vehicle weight by 20 kilos compared to conventional brakes and sets standards in response, fading stability and durability.


In the Cup specification the latest Cup version of the well-proven 3.6-litre six-cylinder boxer (raced since 1998) delivers 400 hp (294 kW) at 7,300/min. Maximum torque is reached at 400 Nm with 6,500 revs per minute. Maximum revs are 8,400. A sequential close ratio six-speed dog-type gearbox with ignition cut allows for very quick upshifting at high speed without lifting the throttle or using the clutch. On the longest straight of the year in Monza the 911 GT3 Cup reaches ca. 275 kph at 8,200 rpm.


Thanks to an aerokit and the adjustable rear-wing, the body generates more downforce than any of its 911-Cup predecessors. The airflow to and from the radiators and brakes was optimised. The weight of 1,120 kgs corresponds to a power-weight ratio of 2.8 kilograms per horsepower - marking another record in the history of Porsche makes cups.


The suspension with the Porsche-optimised spring-strut front axle and multi-link rear axle corresponds closely to the road-going 911. Ride height, camber and track are infinitely adjustable, the anti-roll bars can be adjusted in ten positions within limits set by the regulations.

The 911 GT3 Cup is built on the production line in Stuttgart-Zuffenhausen. The race department in Weissach is responsible for the fine-tuning, running-in and delivery of the vehicles.
