High-Performance Sports Car with Low Fuel Consumption

Stuttgart. Presenting the new 911 GT2 at the Frankfurt Motor Show, Dr. Ing. h.c. F. Porsche AG, Stuttgart, is proudly launching the most powerful 911 so far homologated for road use. Through its striking design wîth large air intakes at the front and the rear wing so characteristic of this very special model, the new 911 GT2 expresses the power and performance potential of the fastest-ever 911 right from the start even at a standstill. Available exclusively wîth rear-wheel drive and a manual six-speed gearbox, this high-performance athlete accelerates to 100 km/h in just 3.7 seconds and reaches a top speed of 329 km/h (204 mph) on average fuel consumption of just 12.5 litres/100 km (equal to 22.6 mpg imp) in the New European Driving Cycle (NEDC), thus offering a level of fuel economy regarded as quite impossible in this performance class just a few years ago.

The power unit of the new 911 GT2 is based on the six-cylinder boxer engine of the 911 Turbo, wîth 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, wîth 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 wîth 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 wîth 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, wîth 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.

Vital Stats
Engine : 3.6 L., 6-cylinder
Power: 530 hp
Torque: 505 ft-lbs

The new 911 GT2 comes as standard wîth PCCB brakes featuring brake discs made of a composite carbon fibre/ceramic compound ensuring maximum stopping power maintained wîth 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 Germany is Euro 159,100.-, the market price including 19 per cent value-added tax Euro 189,496

'Car and Driver' magazine reports 'Of all the variations of the current 911 - Carrera, Carrera S, Carrera 4, Carrera 4S, Cabriolet, Targa, GT3, and Turbo - nothing quickens the pulse and spins tires so readily as the GT2....To create the GT2, Porsche starts with a 911 Turbo, adds power, reduces weight, and removes the all-wheel drive, creating a much more demanding vehicle....'

The engine in the 911 GTS is based on the 6-cylinder boxer engine of the 911 Turbo with air supply driven by two exhaust gas turbochargers featuring variable turbine geometry (VTG). The 3.6-liter boxer engine achieves a maximum output of 530 horsepower. Acceleration is 0 to 60 mph in 3.6 seconds with a track speed of 204 mph.
