With its V10 engine providing more than 600 horsepower and with an array of
cutting edge technologies including a ceramic composite clutch and brakes

The Porsche Carrera GT was introduced in 2004 as a low, sleek, lightweight roadster that is as beautiful to the engineer as it is to the eye. Foul weather protection is also available in the form of two removable panels that can be stored in the front trunk.
Functional Ambience is Interior Theme
Even with its racing-quality performance, the Porsche Carrera GT has a cockpit characterized by functional ambience and the extensive use of high-tech materials. Carbon, magnesium and leather dominate interior materials, with composite components either in their natural state or painted to match the magnesium pieces.
The car's center console is made of composite materials covered in galvanized magnesium and features the chassis number imprinted on the surface. The shift lever is positioned about halfway up the console directly next to the steering wheel.
The seats are finished in smooth leather and have manual adjustment (fore, aft and height) because power motors would add unnecessary weight. The seats are made of a composite carbon shell. Each seat weighs only 23.6 pounds (10.7 kg.), compared to 44.1 pounds (20 kg.) for the seats in a typical Porsche 911.
Air conditioning is optimized for weight and the car comes with a standard air filter system. A glass screen is mounted between the supplemental safety bars to help reduce wind buffeting. Even though the Carrera GT is a serious performance car, it can be equipped with many comfort features, including a navigation system and Bose audio. A battery trickle-charger is included as standard equipment.
Purebred Racing Engine
Porsche's development center in Weissach, Germany, built a 5.5-liter, normally aspirated V10 engine for racing, and that engine's bores have been enlarged to displace 5.7 liters in the Carrera GT. Maximum output is rated at 605 horsepower at 8,000 rpm, with peak torque of 435 lb-ft. The engine has a very low center of gravity, a 68-degree V angle and four valves-per-cylinder heads. The engine block serves as a load-bearing part of the chassis structure, yet is so strong that there is no distortion to the cylinder bores. Using dry-sump lubrication reduces the number of engine components and seals and also helps optimize weight and reliability.
The engine has a closed-deck configuration, a principle carried over from motorsports. This closeddesk architecture enables the cylinders to be cooled by internal water chambers that directly surround the cylinders. Three front-mounted radiators and cross flow cooling ensure optimum heat transfer even under high engine loads.
The engine weighs only 472 pounds (214 kg). The block, crankshaft and camshafts are all made of light alloys. The crankshaft is designed to operate at speeds of up to 8,400 rpm and is both forged and designed for minimum mass inertia and thus offers maximum torsional stiffness.
