wheel torque PORSCHE 911 GT2 2010 5.G Information Manual

The standard could hardly
have been set any higher: the
911 GT2. The aim: to surpass it.
The method: Porsche Intelligent
Performance. The result: the
new 911 GT2 RS.
Not a muscle too few. Not a gram
too much. No more than 500
available. Never was there a more
powerful series produced by
Porsche.
Were there any reservations?

Negative thoughts? Doubt? Not in
the slightest. Fear? No chance.
Our engineers experienced just
one feeling: awe. Before they
started. And definitely af ter they
had finished.
A feeling that goes with you.
Every metre, every second.
Te c h n o l o g y.
Some figures cause astonishment,
others create awe. The increased
power of the 3.6-litre Boxer
engine means that it now delivers
456 kW (620 hp) and maximum
torque is 700 Nm, which is 90 hp
and 20 Nm more than the 911 GT2.
The 911 GT2 RS sprints from
0 to 100 km/ h (62 mph) in 3.5
seconds. From 0 to 200 km/ h
(124 mph) in 9.8 seconds. And
from 0 to 300 km/ h (186 mph)
in 28.9 seconds. Right up to
330 km/h
(205 mph).
The main factor responsible for
this extra power is Porsche Intelli-
gent Performance. An efficiency-
based concept incorporated inside
every Porsche, resulting in the
ef fective light weight design for
example. And the reason why
the 911 GT2 RS is 70 kg lighter
than the 911 GT2.
The body is 26 mm wider at the
front, allowing a 12 mm wider toe
angle and wider tyres. The 19-inch
GT2 RS wheels with central locking
device also provide exceptional
driving dynamics.
The ride height, camber, toe angle,
and the stabilisers on the front and
rear axles can be adjusted individu-
ally for the racetrack. The fact that
the chassis is connected more
rigidly to the body allows for even
more precise steering. For exact
driving and control.High performance demands a
high level of safety. So the new
911 GT2 RS has Porsche Active
Suspension Management (PASM),
Porsche Stability Management
(PSM) and Porsche Ceramic
Composite Brakes (PCCB) fitted as
standard. Additional brake ducts
on the rear axle ensure that the
brakes are effectively ventilated.
Another standard feature is the
Clubsport package including a roll
cage, a six-point safety harness
and a fire extinguisher.
The end result: no series-produced
Porsche has ever reached this
level of performance. None has
achieved faster track times.
None has deserved more awe.
Always there if you go to the extreme:
Awe.

VarioCam Plus.
VarioCam Plus is a two-in-one
engine concept which adapts to
the particular demand for power.
The system switches seamlessly
thanks to the engine management
system. The result is spontaneous
acceleration and smoother run-
ning.
At medium revs and low engine
loads, the system reduces fuel
consumption and emissions by
lowering the valve lift settings
and advancing the timing. Fuel
economy is especially noticeable
at lower revs. High torque values
and maximum power are achieved
with the high valve lift setting,
which results in exceptional engine
power with comparatively low fuel
consumption.
Expansion intake manifold.
Essentially, in all intake systems,
as well as flowing through, the
air also vibrates. These vibrations
consist of both a compression
phase in which the air is com-
pressed and also an expansion
phase in which the air expands.
Until now, more air has meant
more power. The compression
phase of the air vibrations in the
intake system is used to press
more air into the combustion
chamber. The disadvantage is
that, when it is compressed, the
air is also heated. It is therefore
impossible to achieve optimum

ignition of the fuel and air mixture
to maximise power.The expansion intake manifold
adjusts the air vibrations in a com-
pletely different way. It uses the
expansion phase because, when
it expands, the air cools. The mix-
ture in the combustion chamber
therefore becomes cooler – and
optimum ignition can be achieved.
In using the expansion phase,
less air gets into the cylinders.
However, a slight increase
in the charge pressure by the
turbocharger compensates for
this effect. The heating of the
air caused by the higher charge
pressure is in turn compensated
by the charged air cooler. The
result is much higher efficiency
for even greater engine power
and improved fuel consumption

at high loads and engine speeds.
In principle it is quite easy to be in
awe: just breath deeply.
Power transmission.
The light weight six-speed gearbox
in the 911 GT2 RS is designed
specifically for the large amount
of engine power. The gear lever
throw is short and precise – for
rapid and precise gear changes.
Instead of a dual-mass flywheel as
in the 911 GT2, the 911 GT2 RS
uses a single mass flywheel. This
is lighter and the engine can rev
more freely in the upper speed
ranges. Also, the gear ratios have
been readjusted specifically for
use on the racetrack.

Porsche Active Suspension
Management (PASM).
The electronic adjustment of the
shock absorber systems actively
and continuously controls the
damping force – depending on
the driving style and situation –
for each individual wheel.
By pressing a button, the driver
can choose between two setup
modes, ‘Normal’ and ‘Sport ’.
Normal mode is designed for

general road driving and on the
racetrack in the wet. Sport mode
is specially designed for maximum
lateral acceleration and the best
possible traction on the racetrack.
Porsche Stability Management
(PSM).
The limits of driving dynamics.
Those who venture here should
have the necessary equipment –
in addition to driving ability. So,
PSM has been adapted to the
power of the new 911 GT2 RS.
The principle is that in addition
to the ABS there are
two auto-
matic control systems: stability
control (SC) and traction control
(TC). Stability control (SC) controls
lateral dynamics using a range
of sensors to constantly monitor
the direction, speed, yaw velocity
and lateral acceleration of the
car. This information is used to
calculate the actual direction
of travel. If the car starts to go
off course, stability control (SC)
initiates selective braking on
individual wheels to stabilise the
vehicle in critical driving scenarios.
Traction control (TC) with its
integrated ABD (automatic brake
differential), ASR (ant-slip regula-
tion) and EDC (engine drag-torque
control) functions controls the
l ongitudinal dynamics of the car.
This highly sports-oriented traction
control improves traction on vary-
ing road surfaces. Traction control
(TC) also limits excessive force
that can cause the rear to slide out
uncontrollably under full power.
The special feature of PSM in
the 911 GT2 RS is that these
two systems can be switched
of f completely, in t wo stages –
for deliberate sports handling.
In the first stage, the ‘SC OFF’
button in the centre console disa-
bles the stability control (SC). In
‘SC OFF’ mode, the system does
not intervene if the car goes off
course in the lateral direction.
In addition to deliberate steering actions, the car can now also be
driven very dynamically into bends
by acting on the throttle. Traction
control (TC) is still active in this
mode.
In the second stage, the separate
‘SC + TC OFF’ button also disables
the traction control (TC). In this
mode, both the lateral dynamics
control and traction control are
deactivated. Driving is now influ-
enced only by the driver. Another
special feature is that in both the
first stage (SC OFF) and second
stage (SC + TC OFF), the cross-
dynamic control will not reactivate
itself even when the brakes are
applied strongly, including in the
ABS control range. This function
and switching strategy enables
race-oriented driving dynamics –
to meet individual demands for
extraordinary performance on the
racetrack.
