Stuttgart. Three months after the launch of the 911 Carrera ("997" series) Dr. Ing. h.c. F. Porsche AG, Stuttgart, presents the first racing version of the sportscar. The 2005 911 GT3 Cup is tailor-made for customer motorsport with near-standard vehicles. Porsche delivers the car, which will exclusively run in the Porsche Michelin Supercup 2005 next year, ready-to-race to the customers from March 2005. With its predecessor - the Cup Carrera based on the "996" series - being a high performance and competitive sportscar which not only competes in the makes cups but has won various Gran Turismo championships, the new model marks a clear step towards a thoroughbred racing car: the GT3 Cup 2005 features a sequential gearbox with a power shift system. The suspension underwent modifications for higher precision and further improved driving dynamics. For the first time Porsche installs its revolutionary Ceramic Composite Brake (PCCB) to a racing car.
