It has been a week of brochure leaks, starting with the Porsche GT2 followed by the Chevy HHR SS and then BMW M3 Coupe over the weekend. Whether it is second phase of their media push or simply damage control, Porsche has released their teaser press materials announcing the GT2 public debut in Frankfurt this September.

The European market launch starts in November of this year at a base price €159,100 (Excl. 19% VAT) and then making its North American debut early 2008 with a MSRP of $191,700.

Using the same engine as the Turbo model, power is pumped up 50hp to 530hp using bigger turbos and a “flow-optimized turbine housingâ€Â' which increases boost pressure. Also, a new “expansion-typeâ€Â' intake manifold which cools the air/fuel mixture more than the “standard Turboâ€Â' creates more efficient combustion resulting in fuel consumption down by 15% despite the power increase.

Another new feature for the first time is a titanium muffler and tailpipes as standard equipment. Also standard are the carbon/ceramic PCCB brakes discs as well as the electronically controlled Porsche Active Suspension Management (PASM).

See press release below for further details.

PRESS RELEASE

High-Performance Sports Car with Low Fuel Consumption

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 with 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 with 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, 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 â€Â'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 Germany is Euro 159,100.-, the market price including 19 per cent value-added tax Euro 189,496.-.
