New
911 GT2 with 530 Horsepower 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.-.
