2010 PORSCHE 911 GT2 steering

7 |
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.

Chassis.
Closer to the ground – yes. On its
knees – no. The requirements for
the new 911 GT2 RS chassis were
high: driving characteristics that
are typical of a race car, on both
the road and the racetrack.
This car is around 25 mm lower
than the 911 Carrera and its sys-
tematic lightweight construction
keeps the total weight and the
weight of unsprung masses low.
For extraordinary agility, excellent
driving safety and stability, espe-
cially when cornering.
Wider wings on the front axle enable
a 12 mm wider toe angle com-
pared to the 911 GT2 and the use
of wider tyres. For even more
grip, improved steering and higher
cornering speeds.
The front suspension with
enhanced hub carriers combines
McPherson-type struts with longi-
tudinal and transverse links. Each
front wheel is precisely located,
ensuring excellent directional
stability and superior handling in
every driving situation.
The rear axle has multi-link suspen-
sion featuring LSA construction –
light, stable and agile. The reduced
weight design of the rear axle’s
aluminium transverse arm and
diagonal struts ensures excellent
driving dynamics.
Ride height, camber, toe angle and
also the stabilisers on the chassis
can be adjusted on the front and
rear axles and therefore adapted
to the required driving behaviour. The rigid connection bet ween the
chassis and the body, e.g. metal
support bearings with ball joints
at the front and the rigid cross-
members at the rear, makes trans-
mission less elastic and ensures
more precise steering to enable
better handling.
Cooling air is delivered efficiently
to the front brakes thanks to
the brake air spoiler. In the new
911 GT2 RS there is additional
brake ventilation on the rear axle.
In short, the chassis exploits the
road to the full. Inspiring awe.
Wheels.
The link between the enormous
power of the new 911 GT2 RS and
the road: the white gold metallic
painted 19-inch GT2 RS wheels.
Their central locking device is
anodised and bears the ‘RS’ logo –
also in a white gold metallic finish.
The central locking device is
derived from motorsport. Its

advantages include bet ter driving
dynamics and performance thanks
to lower rotating masses. And,
of course, faster wheel changes.
An enormous advantage – espe-
cially on the racetrack.
The dimensions: on the front
axle 9 J x 19 with sports tyres
1)
245/35 ZR 19 and on the rear
axle 12 J x 19 with sports tyres
1)
325/30 ZR 19. Tyre Pressure
Monitoring (TPM) comes as stand-
ard and provides early warning
of any tyre pressure loss via a
display on the on-board computer.
You can still take off
without losing contact with the ground.

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.

Bodyshell structure.
The reinforced bodyshell of the
new 911 GT2 RS contains a highly
resilient passenger cell which
offers exceptional crash protection,
whilst still ensuring the vehicle
remains lightweight. A system of
longitudinal and transverse mem-
bers, patented by Porsche, is
used at the front. In the event of a
collision, this distributes the forces
and minimises deformation of the
passenger cell. An extremely rigid
bulkhead cross-member made from
super high-strength steel absorbs
impact forces from the front
longitudinal members to protect both front footwells. Reinforced
doors contribute to the overall
rigidity of the car. In the event
of a front impact, an additional
load path is used to channel ener-
gy through the upper part of the
bodyshell and thus further protect
the passenger cell. Easily replace-
able collision elements protect
the bodyshell in minor accidents.
The high proportion of aluminium
alloys and high-strength steel
used contributes towards the
good power-to-weight ratio of
the 911 GT2 RS.
Driver and passenger airbags.
In the 911 GT2 RS, the airbag
technology has been adapted for
the car. The full-size front airbags
are activated in t wo stages
depending on the seriousness and
type of accident (e.g. frontal or
diagonal from the front). In low-
speed collisions, the airbag is
only partially inflated, thereby mini-
mising discomfort to occupants.
Porsche Side Impact Protection
System (POSIP).
The standard POSIP system con-
sists of side impact protection
in the doors and side airbags for
the head. The large volume of the
airbags provides protection over
the whole seat-adjustment range.
Padded elements on the door
panels also protect the occupants.
The optional sports bucket seats
and adaptive sports seats have
a thorax airbag instead of the pad-
ded elements.
Other safet y features in the new
911 GT2 RS are the headrests
integrated in the seat backs, a
safety steering column, three-point
seat belts in red with belt height
adjustment, belt tensioner and belt
force limiter, energy absorbing
structures in the dashboard and
fire resistant materials throughout
the interior.

Instruments.
The instruments in the new
911 GT2 RS are designed for
pure sports performance. They
provide quickly accessible infor-
mation and are ergonomic and
clearly visible – just like the rev
counter with a titanium blue dial
located in the centre of the five
round instruments. The instru-
ment needles and dial markings
are coloured yellow. For optimum
acceleration, the gearshift indica-
tor is located in the rev counter.
The integrated on-board compu-
ter provides you with information
on boost pressure, average fuel
consumption, speed and distance
lef t to travel.
Interior materials.
The materials used in the interior
meet the demands placed
on a thoroughbred racing car.
Alcantara, for example, which
offers exceptional grip and
easy-care properties.
So red Alcantara has been used
wherever there is hand contact.
On the steering wheel, gear lever,
handbrake lever and the door
handles. Also on the arm rests
in the door panels, the storage
compartment lid in the central
console, the roof lining and the
centre of the seats.
It provides a sport y contrast with
the otherwise predominant colour
in the interior: pure black.This sporting trend continues
with a material that is typical of
motorsport: carbon. The standard
lightweight bucket seats are made
from carbon and are covered in
leather/Alcantara. The badges on
the dashboard and the door sills
have a carbon finish and bear the
‘RS’ logo.
At no extra cost a black leather
trim with either red or black
Alcantara is available.
Steering wheel.
The three-spoke GT2 RS steering
wheel has manual reach and
height adjustment. It is upholstered
in Alcantara to ensure a good grip.
A striking feature is the yellow top
centre marking on the steering
wheel.
Lightweight bucket seats.
Fit ted as standard in the new
911 GT2 RS are lightweight carbon
bucket seats (page 32). They are
designed to provide exceptionally
good side support and feature
manual fore/aft adjustment. In
place of a thorax airbag, the door
panels have no storage pocket and
are padded. The lightweight bucket
seats together weigh only about
20 kg – for a noticeable weight
reduction. The seats are covered
with black leather with the seat
centres in red Alcantara.
Sports bucket seats.
Available as an option are sports
bucket seats (page 32) with a
folding backrest, integrated thorax
airbag and manual fore/aft adjust-
ment. The backrest shell is made
from glass and carbon-fibre
reinforced plastic with a carbon
surface. Depending on the
trim, the seats are covered in
leather/Alcantara in black/red
or black/black.
Adaptive sports seats.
Available as a no-cost option in
the new 911 GT2 RS are adaptive
sports seats with thorax airbag
(page 32). They feature electric
fore/aft, height and seat squab
angle adjustment and the side
bolsters on the seat and backrest
can be adjusted individually.
For the perfect fit to provide
side support when cornering
and greater comfort on straight
stretches. Depending on the

trim, the seats are covered with
leather/Alcantara in black/red
or black/black.
Completely free space.
