The ultimate 911 boasts High Performance and Low Fuel ConsumptionNew Porsche 911 GT2 with 390 kW
Australia. When the new Porsche 911 GT2 goes on sale in Australia in March next year it will be the most powerful 911 model ever homologated for road use.
It will boast 390 kW of power (530 hp) at 6,500 rpm and 680 Nm of torque (501 lb-ft) between 2,200 and 4,500 rpm.
The power unit of the new 911 GT2 is based on the 3.6-litre six-cylinder boxer engine of the 911 Turbo, with air supply by two exhaust gas turbochargers featuring variable turbine geometry (VTG). With an unladen weight of 1,440 kg the 911 GT2 offers a power-to-weight ratio of just 3.69 kg per kilowatt.
Porsche’s ultimate 911 is characterised by a striking exterior design that includes large air intakes in the front bumper and a twin deck rear wing. Even from a standstill its performance intentions are clear.
The GT2 makes its public debut at the Frankfurt Motor Show in September.
Available exclusively with rear-wheel drive and a manual six-speed gearbox, this high-performance 911 accelerates to 100 km/h in just 3.7 seconds and reaches a top speed of 329 km/h (204 mph) with an average fuel consumption of just 12.5 litres/100 km in the New European Driving Cycle (NEDC). This level of fuel economy was considered quite impossible in this performance class just a few years ago.
The increase in the GT2’s engine power by 37 kW and 60 Nm over the 911 Turbo is attributed to the two turbochargers featuring larger compressor wheels and flow-optimised turbine housings, 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 also sets new standards 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 to 9 kg versus a comparable component made of stainless steel.
The new 911 GT2 is fitted 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 unsprung weight by 20 kg versus comparable grey cast-iron discs.
The electronically controlled Porsche Active Suspension Management system (PASM) is part of the GT2 package, as are 19-inch light-alloy wheels running 235/35 ZR 19 sport tyres on the front and 325/30 ZR 19 at the rear.
The new 911 GT2 will be on sale in Australia in March 2008, priced from $425,700.
