The power unit of the new 911 GT2 is based on the six-cylinder boxer engine of the 911 Turbo, with air supply driven by two exhaust gas turbochargers featuring variable turbine geometry (VTG). The 3.6-litre boxer engine achieves a maximum output of 530 (SAE) horsepower, an increase of 50 horsepower from the previous 911 GT2. The power increase is provided by two turbochargers with a larger compressor wheel and a flow-optimized turbine housing raising turbocharger pressure to an even higher level. The new 911 GT2 comes as standard with PCCB brakes featuring brake discs made of a composite carbon fiber/ceramic compound ensuring highly consistent and maximum stopping power. Also standard is the electronically controlled Porsche Active Suspension Management (PASM) system.
North American debut in early 2008 at a US price of $191,700.
