Takeoff.
Engine.
The engineers knew exactly what
their objective was: to make the
new 911 GT2 RS the most powerful
Porsche for the road.
Objective achieved. The water-
cooled six-cylinder bi-turbo Boxer
engine with four-valve technology,
variable turbine geometry (VTG)
and VarioCam Plus delivers its
power through the rear axle. From
a displacement of 3,600 cm
3
, it
generates an enormous 456 kW
(620 hp) at an engine speed of
6,500 rpm. The maximum torque
of 700 Nm is available from
2,250 rpm. From 0 to 100 km/h
(62 mph) takes just 3.5 seconds.
To 200 km/h (124 mph) only
9.8 seconds, and to 300 km/h
(186 mph) just 28.9 seconds.
Maximum boost pressure is not
reached until a speed of 330 km/h
(205 mph). The weight-to-power
ratio that is essential for this kind
of performance is just 2.21 kg/hp.
A consistent supply of oil to the
engine – even at high cornering
speeds – is achieved using a
dry sump lubrication system with a
separate engine oil reservoir. The
oil is cooled by an oil-water heat
exchanger.
Variable turbine geometry (VTG).
Unlike a conventional turbo, the
incoming exhaust gas is directed
onto the turbine by electronically
controlled guide vanes. The angle
of these vanes can be adjusted so
that the flow speed of the exhaust
gas and, therefore, the momentum
on the turbine can be changed.

911 GT2 RS: 700 Nm at 2,250 rpm, 456 kW (620 hp) at 6,500 rpm
This means that a large amount of
power can be generated from the
turbo even at low engine speeds
with small amounts of exhaust gas
– for much higher boost pressure,
excellent cylinder filling and more
torque.
The torque curve therefore rises
sooner – and then stays uniformly
high for a long time. The increase
in power and torque is helped not

only by the fact that the maximum
boost pressure has been in-
creased to 1.6 bar, but also by
the new charged air cooler in the
911 GT2 RS. The end result is
an extraordinary response and
acceleration that will leave you
speechless.
