Porsche 911 Turbo
Power.
Torque. Acceleration. All in plentiful supply. Nothing else can match
that energy - except the car's design. A single glance is all it takes
to realize that fact.
The most impressive view is the one that
others will see most of all: the rear. The fixed rear wing with integral
lip spoiler ensures optimum stability at speed.
As the car
accelerates and you're pressed into your seat, air is forced through the
intake openings on the rear wing uprights and into the engine
turbocharging system. This 'ram air' effect has a key role to play in
the exceptional efficiency of the engine. Since air is already being
forced into the turbos, there is less resistance from the compressors
and therefore less back-pressure in the exhaust, which means greater
engine performance.
The six-cylinder twin-turbo boxer engine is a
compact unit offering excellent cylinder charging and torque-curve
characteristics as well as first-rate balance with minimal vibration.
The flat-six design allows a low center of gravity with resulting
advantages for traction and driving dynamics. The exhaust system on the
911 GT2 produces a warm, deep and bass-rich sound - even when the engine
is idling.
The cylinder heads are made from an extremely
heat-resistant lightweight alloy. Each cylinder bank has two overhead
camshafts driving a set of four valves (two inlet and two exhaust) on
each individual cylinder. The valves are arranged in a V formation and
have a highly efficient dual-spring closing action enabling higher
engine speeds. Performance is enhanced with the aid of both Variable
Turbine Geometry (VTG) and VarioCam Plus (variable valve timing and lift
on the inlet side).
The benefits are not only greater power and torque with this luxury car, but also better fuel economy and lower emissions.
