Porsche will unveil the production version of its new Carrera GT, its most powerful sportscar, at the Geneva Motor Show in March.

According to , one Porsche official said: “Our aim is to bring the driver of the Carrera GT as close as possible to a full-blown racetrack experience on the road”.

Its 10-cylinder powerplant with dry-sump lubrication is based on Porsche's 5,5-litre V10 naturally aspirated engine developed especially for racing.

reported that for production, technicians have increased the displacement to 5,7 litres. Maximum output is 456 kW at 8 000 r/m. Porsche claims the mid-engined rear-drive car has a top test-track speed of 330 km/h and accelerates from zero to 100 km/h in 3,9 seconds. Its specially developed six-speed manual gearbox allows it to reach 200 km/h in 9,9 seconds.

With a length of 4,61 m, a width of 1,92 m, a height of 1,16 m and a wheelbase of 2,73 m, the roadster weighs 1,380 kg.

The Carrera GT's extremely light magnesium wheels are produced with a special forging process and are offered for the first time on a mass-produced vehicle. The tyres were specially developed for the Carrera GT (265/35 ZR 19 in the front, and 335/30 ZR 20 in the rear).

The Carrera GT's monocoque and entire sub-frame are made of carbon-fibre reinforced plastic (CFRP), and Porsche has applied to patent this technology. Carbon is the only material that, after complex processing, can meet the requirements needed to combine top-class driving performance and driving dynamics with minimum weight at maximum rigidity.

With the vehicle's attainable top speeds, aerodynamics play a crucial role. The Carrera GT has an underbody geometry that can only be found in similar form in pure racing sportscars. The underbody is completely cased in carbon fibre and provides an additional suction effect thanks to its rear diffusor and flow channels.

The new Porsche roadster has a simple-operation roof system. It consists of two individual carbon fibre lightweight shells, each weighing only 2,4 kg. These shells can be stored in the front luggage compartment.

The first Carrera GT models produced at the Porsche plant in Leipzig, Germany, will be delivered to customers at the end of 2003. It was first shown in concept form in Paris in 2000.
