(from Porsche Press
Release) 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 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 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 Porsches 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
