carbon air outlet in front of the
front lid guides the air flowing
through the central radiator up
over the vehicle, thus increasing
the downforce on the front axle.
Immediately noticeable are the
front wings which are 26 mm
wider, enabling a wider toe angle
and the use of wider tyres. The
19-inch GT2 RS wheels have a
white gold metallic finish.
A further striking feature is the
black ‘GT2 RS’ logo on the side.
The rear with a carbon middle
section makes an impression.
And the carbon lip on the fixed
rear wing sits 10 mm higher.
For extreme driving stability.
For greater efficiency and more
engine power, as the speed in-
creases, additional air is pressed
into the intake channel through
the air inlet channels in the wing
supports. This ram air system
builds up the air in front of the
Lightweight construction.
Anyone who wants to go beyond
the horizon has to work on their
performance – and concentrate
on strength. The way to achieve
this is to make sacrifices. But only
with regard to weight. The new
911 GT2 RS is 70 kg lighter than
the 911 GT2. Its weight-to-power
ratio: just 2.21 kg/ hp. For excel-
lent performance. And with rela-
tively moderate fuel consumption.
This is achieved thanks to a whole
series of modifications. In parti-
cular, the use of materials that
are more typically found in motor-
sport. The front lid, the side air
intakes on the charge air cooler,
the slats in front of the front lid,
the rear middle section, the rear
spoiler lip and the rear wing are
all constructed from carbon. As
are the lightweight bucket seats
and door sills with the ‘RS’ logo.
The front mud flaps are also
available in carbon as an option. Instead of the usual steel, the
diagonal struts on the rear axle
are made from aluminium. As are
the fixed calipers of the PCCB on
the front and rear axle. The engine
cover, rear window and rear side
windows are made from a synthetic
material. In addition to this, the
new 911 GT2 RS has light weight
door panels with side pads and
door pulls. Throughout the body,
much of the soundproofing has
been removed and the interior
soundproofing has also been
reduced.
The lightweight single mass
fly wheel makes the engine even
more responsive. Weight has
even been reduced in the body
structure: there are no fittings for
a roof transport system and there
are no reinforcements for fasten-
ing the seat belts in the floor.
The battery in the new 911 GT2 RS
is also lighter. A lithium ion battery
which provides an additional weight
saving of over 10 kg compared to the conventional standard battery
is available as an option. The
lithium ion battery is inserted in
the vehicle and can easily be

replaced by the standard battery
for use on the racetrack.
In addition, you can opt to do
without the CDR-30 audio system,
the air conditioning and the

Clubsport package. To achieve an
even lower power-to-weight ratio.
Design.
Even the appearance of the new
911 GT2 RS leaves no room for
doubt: it is more powerful than
before.
Power is demanding. So, with
regard to aerodynamics, the design
has been aimed at achieving the
best possible cooling and the
greatest possible downforce. The
large air inlets ensure that the air
is directed straight to the central
radiator and the front brakes. The turbochargers. This relieves the
turbochargers, thus lowering
exhaust gas back pressure and
increasing engine power.
To sum up: a drag coefficient
value of only
0.34. Along with
increased downforce on the front
and rear axles. For better road
holding, greater stabilit y and
excellent handling. In short, a
design that fulfils its purpose:
to create awe.

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 cm3, i t
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. 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

Takeoff.
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.
