WEISSACH, Germany -- Porsche engineering boss Wolfgang Dürrheimer used only the best materials for the new 330kph Carrera GT.
"This demonstrates what technical possibilities we have," he says. "Also, when choosing partners and suppliers, the benchmark was very high and only the best were taken on board."
With the GT, which will be launched in Germany in September and limited to 1,500 units, Porsche aims to prove that one sports car does not have to be like another.
Chassis and aggregate subframes made of carbon fiber? Of course. The chassis, which weighs only 100kg, has carbon fiber top and bottom layers, surrounding some honeycomb-shaped materials made of aluminum and "Nomex," a resin-impregnated material similar to paper that is used in aeronautics.
In high-stress areas more than 10 layers of carbon fiber are placed on top of each other - mainly new unidirectional materials with fibers that run in just one direction.
For the cockpit and the lightweight seats the carbon fiber is combined with aramide synthetic fiber to prevent splintering.
Chassis and aggregate subframes are manufactured by Italian specialist ATR, which also works for Ferrari. The Porsche components are made in a new and separate workshop, in order to maintain secrecy.
Brakes and clutch are also high-tech, made of extremely strong ceramic composites strengthened with carbon fiber. The unusually compact and light PCCC clutch (Porsche Ceramic Composite Clutch) is a world first. Its titanium frames allow a power transmission of 1,000Nm. The engineers would have liked to combine the 612hp V-10 engine transmission unit with a twin-clutch transmission, such as the one Porsche formerly used in racing cars. But that would have lengthened the two-year development period and taken the project over budget.
