In the first paragraph Porsche supports that despite being the most powerful and fastest 911 so far homologated for road use, the GT2 manages an avg. fuel consumption of just 12.5 liters/100 km (equal to 22.6 mpg imp). Umm, did we read correct; an avg consumption of 12.5 liters/100 km in a 530Hp sports car! Who and how the hell managed to accomplish this? Honestly now, he or she should seriously consider opening up a school to teach us the art of frugal driving… -Click “Read More…” for the press release and the high-re image gallery
PRESS RELEASE: High-Performance Sports Car with Low Fuel Consumption
The power unit of the new 911 GT2 is based on the six-cylinder boxer engine of the 911 Turbo, with air supply by two exhaust gas turbochargers featuring variable turbine geometry (VTG). The 3.6-litre boxer engine achieves its maximum output of 530 bhp (390 kW) at 6500 rpm, with maximum torque of 680 Newton-metres maintained consistently between 2,200 and 4,500 rpm. With its unladen weight of 1,440 kg or 3,175 lb, finally, the 911 GT2 offers a power-to-weight ratio of just 2.72 kg/6.00 lb per horsepower.
The increase in engine power by 50 bhp over the ”regular“ power unit is provided in the new 911 GT2 by two turbochargers with a larger compressor wheel and a flow-optimised turbine housing raising turbocharger pressure to an even higher level. And for the first time Porsche’s engineers have combined the turbocharged engine with an expansion-type intake manifold – a genuine revolution on turbocharged power units.
The expansion intake manifold uses the principle of oscillating air in the intake manifold during the cooler expansion phase, keeping the temperature of the fuel/air mixture lower than in the 911 Turbo. This, in turn, means a significant increase in all-round efficiency, with fuel consumption down by up to 15 per cent under full load despite the increase in engine output.
The 911 GT2 offers new achievements also in terms of emission management and control: This is the first Porsche homologated for the road to feature a rear silencer and tailpipes made of titanium as standard equipment. This expensive material reduces weight by approximately 50 per cent versus a comparable component made of stainless steel to just 9 kg.
The new 911 GT2 comes as standard with PCCB brakes featuring brake discs made of a composite carbon fibre/ceramic compound ensuring maximum stopping power maintained with an extremely high level of consistency. A further advantage is that PCCB brakes reduce the weight of the unsprung masses versus comparable grey cast-iron discs by approximately 20 kg or 44 lb.
Yet another feature fitted as standard is the electronically controlled PASM Porsche Active Suspension Management. (PASM). The GT2 comes on 19-inch light-alloy wheels running at the front on 235/35 ZR 19, at the rear on 325/30 ZR 19 sports tyres.
The new 911 GT2 will be at the dealership in November 2007. The base price of the car in
