From Porsche Press release:

ATLANTA, July 16 /CNW/ - With a stunning 530 turbocharged horsepower and the most revolutionary design in the industry, Porsche will reveal its most
powerful production 911 ever on September 11, 2007 at the Frankfurt Motor
Show. Based on the current 911 Turbo, the 911 GT2 will easily ascend to lead
the impressive Porsche family of vehicles.

New features such as large air intakes at the front and the rear wing,
coupled with the rear-wheel drive and manual six-speed gearbox, express the
elite performance abilities that are exclusive to this outstanding model. This
high-performance athlete accelerates to 60 mph in just 3.6 seconds and reaches
a top track speed of 204 mph.

530-Horsepower Twin-Turbo Engine

The power unit of the new 911 GT2 is based on the six-cylinder boxer
engine of the 911 Turbo, with air supply driven by two exhaust gas
turbochargers featuring variable turbine geometry (VTG). The 3.6-litre boxer
engine achieves a maximum output of 530 (SAE) horsepower, an increase of 50
horsepower from the previous 911 GT2. The power increase is provided by two
turbochargers with a larger compressor wheel and a flow-optimized turbine
housing raising turbocharger pressure to an even higher level.

Decreased Fuel Consumption

The new 911 GT2's expansion intake manifold, which uses oscillating air
in the intake during the cooler expansion phase, keeps the temperature of the
fuel/air mixture even lower than in the 911 Turbo. This results in a
significant increase in all-round efficiency, with fuel consumption down by up
to 15 percent under full load despite the increase in engine output. This is a
genuine innovation for turbocharged power units.

Functional Design Features

A number of elements set the new 911 GT2 apart including the new
achievements in emission management and control. This is the first Porsche
homologated for the road to feature a muffler and tailpipes made of titanium
as standard equipment. This expensive material reduces weight by approximately
50 percent vs. a comparable component made of stainless steel.

The new 911 GT2 comes as standard with PCCB brakes featuring brake discs
made of a composite carbon fiber/ceramic compound ensuring highly consistent
and maximum stopping power. Also standard is the electronically controlled
Porsche Active Suspension Management (PASM) system.

The GT2 comes on 19-inch light-alloy wheels filled with 235/35 ZR 19
front sport tires and 325/30 ZR 19 rear sport tires. It is scheduled to make
its North American debut in early 2008 at a US price of $191,700.
