2010 PORSCHE 911 GT2 ECO mode

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.

Porsche Ceramic Composite
Brake (PCCB).
Being in awe also means knowing
when
to brake – when necessary.
The new 911 GT2 RS is equipped
as
standard with the Porsche
Ceramic
Composite Brake (PCCB).
This braking technology has already
demonstrated its performance
credentials on the racetrack,
for example, in the vehicles of
the Porsche Mobil 1 Supercup.
Its
ceramic brake discs have a
diameter of 380 mm at the front
and 350 mm at the back – for
excellent braking power. The ceramic discs are made from
a specially treated carbon-fibre
compound that is silicated in a
high-vacuum process at approxi-
mately 1,700 °C. The resulting
brake discs are much harder and
therefore more resistant to exces-
sive temperatures than cast iron
discs. Typical of PCCB, the low
thermal expansion prevents defor-
mation under heavy braking. Fur-
thermore, the ceramic brake discs
are totally resistant to corrosion
and offer bet ter noise-damping
properties.The use of six-piston aluminium
monobloc fixed calipers on the front
axle and four-piston aluminium
monobloc fixed calipers on the
rear axle ensures a very high and,
above all, constant braking pres-
sure. The brake response is much
faster and more precise and
requires only moderate input.
All the necessary ingredients are
there for short braking distances,
especially in tough conditions.
And safety is also increased when
braking from high speeds, thanks
to the excellent fade resistance
of PCCB.
The key advantage of the ceramic
brake system is in the extremely
low weight of the brake discs: they
are approximately 50% lighter than
cast iron discs of similar design and size. In the new 911 GT2 RS
the calipers on the front and rear
axles are made from light weight
aluminium giving an additional
weight saving of approx. 4.8 kg
compared with stainless steel
calipers. This doesn’t just have
a positive effect on driving per-
formance and fuel consumption.
Above all, it means that the
unsprung and rotating masses
are reduced.
The result is improved road-

holding and comfort, especially on
uneven roads. As well as greater
agilit y and even bet ter handling.
Please note that circuit racing,
trackday use and other forms
of performance driving can sig-
nificantly reduce the service life
of even the most durable pads
and discs. As with conventional
high-performance braking sys-
tems, we recommend that all
brake components be profession-
ally inspected and replaced where
necessary after every track event.
Safety means being able to rely on the
systems working in the background.

CDR-30 audio system.
The new 911 GT2 RS is fitted as
standard with the CDR-30 audio
system with 5-inch (monochrome)
display and MP3 compatible CD
player.
The FM twin tuner with RDS diver-
sity has a total of 30 memory
presets, dynamic autostore and
speed - dependent volume control.
And, of course, great sound. This
is provided by the four loudspeak-
ers and an integrated 2 x 25 Watt
amplifier.
Or you can opt to delete the
CDR-30 for a further weight saving.
Sound Package Plus.
For discerning ears: the optional
Sound Package Plus. Nine high-
quality loudspeakers and an exter-
nal amplifier with a total output
of 235 Watts provide a sound
experience that is in perfect
harmony with the interior space.
The sound set tings are adjusted
via the CDR-30 audio system
or the optional Porsche
Communication Management
(PCM).
PCM including navigation
module.
If required, in conjunction with
the Sound Package Plus, you

can also have Porsche Communi-
cation Management (PCM) for the
911 GT2 RS. This efficient central
information and communication
system is impressively versatile
and surprisingly easy to use. The main feature is the 6.5-inch
colour touchscreen with a durable,
easy-to-clean coating. It is func-
tional, innovative and easy to use.
Its very clear layout – a maximum
of five list entries per page –
means it is reliable and quick
to
use. You can also operate
PCM using the buttons on the
right- hand side.
For radio listeners, there are up
to 42 presets, an FM t win tuner
frequency diversit y with RDS which
constantly scans for the best
signal for the selected station.
The integrated single CD/ DVD
player supports the MP3 format.
The GPS navigation module
in corporated in PCM has a hard
drive with map data for most
European countries. For rapid
route calculation, always with a
choice of three alternative routes.
When viewing a map, you can choose between a 3D perspective
and a 2D display which now also
shows height profiles. In split-
screen mode, in addition to the
current map view, you can also
display a list of icons that repre-
sent dynamic route guidance.
Available as an option for PCM
is the quad-band GSM telephone
module with a Bluetooth
® inter-
face, which is very easy to use and
has improved speech quality.
For both PCM and the CDR-30
audio system there is an optional
mobile phone preparation kit
for the Bluetooth
® connection of
mobile phones which only support
the Handsfree Profile (HFP).
1)
Universal audio interface.
Also available for PCM and
CDR-30 is a universal audio inter-
face. You can use this to connect
your iPod®, a USB stick/ MP3
player or any other audio source.
The iPod
® or USB stick is easily
operated via PCM.
Chrono Package for CDR-30.
The optional Chrono Package
includes a swivelling, dashboard-
mounted analogue and digital stop-
watch. The analogue display shows
the elapsed hours, minutes and
seconds. Seconds, tenths of sec-
onds and hundredths of seconds
appear on one display – while at
the same time there is a digital
display on the instrument cluster.
