Porsche High-Performance Sports Car with Technology of the Future

World Premiere for Carrera GT at the Geneva Salon

Stuttgart, Germany. The Carrera GT, the latest high performance sportscar from Dr. Ing. h.c. F. Porsche AG, Stuttgart, not only demonstrates the technological possibilities available today in sportscar construction, but also gives an insight into Porsche technology that could be deployed in the future.The Carrera GT will make its debut in March at the Geneva Automobile Salon, where the production version of the car will be on public display for the first time ever. Even at a glance, the carbonfibre bodywork and overall construction of the Carrera GT betray that its origin lies in motor sport.Porsche's latest sportscar creation has a thoroughbred racing engine.The ten-cylinder engine with dry-sump lubrication is based on the 5.5 litre V10 naturally-aspirated engine that was developed especially for motorsport.To suit series production, engineers at the Porsche Research and Development Centre in Weissach have increased the displacement to 5.7 litres.The maximum output is 450 kW (612 hp) at 8,000 rpm and the maximum torque is 590 Nm (437 ftlb.).The Carrera GT enters a whole new dimension in terms of driving performance.It attains a maximum speed of 330 kilometres per hourand accelerates from zero to 100 km/h in just 3.9 seconds. The Carrera GT also completes the sprint from zero to 200 km/h in a mere 9.9 seconds.A specially developed manual gearbox, comprising six gears, ensures optimal transmission of the engine power. The specifications demanded a consistent lightweight construction and that the designers should concentrate on the most essential features of a sports car. With a length of 4.61 metres, a width of 1.92 metres, a height of 1.16 metres and a wheelbase of 2.73 metres, the roadster has a dry weight of 1,380 kilograms. The construction concept is a world first for road and racing vehicles – both the monocoque and the entire sub-frame are made of carbonfibre reinforced plastic (CFRP). Porsche has applied for a patent for this trail blazing principle. Carbon is the only material that, after complex processing, can meet the prerequisites to combine top-class driving performance and driving dynamics with minimum weight and maximum rigidity. With attainable speeds of more than 300 km/h, aerodynamics plays a crucial role. To achieve as high output coefficients (“downforce”), the Carrera GT has an underbody geometry that can only be found in thoroughbred racing (sports) cars. The underbody is completely cased in carbonfibre and its rear diffuser and airflow channels provide an additional suction effect. The Carrera GT decelerates on Porsche Ceramic Composite Brake (PCCB). Porsche has supplied these high performance brakes since 2001 and is the first manufacturer to include them in a series-production vehicle (GT2). A global innovation takes care of power transmission: the PCCC (Porsche Ceramic Composite Clutch). The PCCC's high efficiency, small dimensions and enormous endurance set it apart from other transmission systems. The Carrera GT's extremely light magnesium wheels are produced in a very special forging process and deployed for the first time in a series production vehicle. The tyres have been especially developed and tuned for the Carrera GT – with front dimensions of 265/35 ZR 19 and 335/30 ZR 20 to the rear. The new Porsche roadster possesses a simple-operation roof system. It consists of two individual carbonfibre, lightweight shells (each weighs only 2.4 kilograms), which can be accommodated in the front luggage compartment. The Carrera GT will be produced at the new Porsche state of the art production facility in Leipzig and deliveries to customers will begin at the end of 2003. The price will be confirmed later in the year.
