2009 PORSCHE 911 display

This double clutch provides
an alternating, non positive
connection bet ween the t wo
half-gear
boxes and the engine
by means of t wo separate
input shafts
(input shaf t 1 is
nested inside the hollowed- out
input shaft 2).
The flow of power from the
engine is only ever transmit ted
through one half-gearbox and
one clutch at a time, while the
next gear is preselected in the
second half-gearbox. During a
gear change, therefore, a conven -
tional shift no longer takes place.
Instead, one clutch simply opens
and the other closes at the same
time. Gear changes can therefore
take place within milliseconds.
Clutch 1 controls the first half-
gearbox, which contains the odd
gears (1, 3, 5, 7) and reverse.
Clutch 2 controls the second,
which contains the even gears
(2, 4, 6).
The Sport Chrono Package Turbo
with dynamic engine mount system (standard on 911 Turbo S
models) provides PDK with t wo
additional functions, ‘Launch

Control’ and ‘motor sport- derived
gearshif t strategy’ (page 60).
PDK – sport y, comfortable and
ef ficient. Characteristics that have
been given some thought else -
where too: in the specification for
the 911 Turbo model range.
Three-spoke sports steering
wheel with gearshift switches.
If combined with the optional
PDK, the three-spoke sports
steering wheel (standard on
911 Turbo and 911 Turbo Cabriolet)
has t wo ergonomic switches.
One press with the thumb and
PDK shif ts up. One pull with the
index finger and PDK shifts down.
Either the right or lef t hand can
be used.
The steering wheel rim and airbag
module are covered in smooth
leather, whilst the spoke covers
are painted in Black.
When combined with the Sport
Chrono Package Turbo with
dynamic engine mount system,
there is an additional display
above the airbag module. It tells
you whether the SPORT, SPORT
PLUS and Launch Control func -
tions are activated.
On request, the three-spoke
sports steering wheel with gear -
shift switches for the 911 Turbo
and 911 Turbo S models is also
available as a multifunction steer -
ing wheel (in leather, Aluminium
Look, carbon or macassar).
Steering wheel heating is avail -
able as an option.
Three-spoke sports steering
wheel with gearshift paddles.
The three-spoke sports steering
wheel with gearshif t paddles
(standard on 911 Turbo S models,
optional for 911 Turbo models)
allows you to make motorsport-
st yle gear changes. The paddles
are made from a strong alloy and
are ergonomically located behind the right and lef t steering wheel
spokes. Pull the right-hand paddle
and PDK shifts up. Pull the

left-hand paddle and the PDK
shifts down.
Visually, the steering wheel is
distinguished by its distinctive
high-qualit y t win-spoke design
and silver-coloured galvanised
spoke cover. The airbag module
is finished in the same colour as
the steering wheel rim.
This steering wheel also has an
additional display when combined
with the Sport Chrono Package
Turbo with dynamic engine mount
system. Located in the lef t and
right-hand steering wheel spokes,
it tells you whether SPORT,
SPORT PLUS and Launch Control
are activated.
Another feature reminiscent of
the world of motorsport is the top
centre marking on the steering
wheel rim.

Steering.
Sensitive and direct, the power-
assisted steering also of fers
accurate feedback from the road.
For a sportscar, driver effort is
minimal. In short: all the precision
of a race- designed system, yet
perfect for everyday road use.
One of the key features of the
steering system is the variable-
ratio gearing. Around the

straight-ahead position, the ratio
is less direct, enabling smoother
manoeuvres on the motorway. It
also reduces the risk of excessive
steering inputs which could
destabilise the car at high speed.
Agilit y and feedback, however,
are maintained.
Turn the wheel harder and the
ratio becomes more direct,
enabling bet ter control through
low-speed corners as well as
easier parking manoeuvres.
The turning circle is a modest
10.9 metres.
19-inch 911 Turbo II wheels.
Fit ted as standard to 911 Turbo
models, the 19 -inch 911 Turbo II
wheels seamlessly combine
function and design.
The car has 8.5 J x 19 wheels
at the front combined with
235/35 ZR 19 t yres. At the rear
are 11 J x 19 wheels with
305/30 ZR 19 t yres. The wheels
are forged, of course, to reduce
weight and unsprung masses.
The material is also very strong,
making it possible to achieve a
fine spoke wheel design which
provides bet ter ventilation of the
brakes.
The five-spoke design is st ylish
and distinctive. The linear
t win spokes have a high -sheen
surface finish, contrasting
with the titanium - coloured base
paint. Part of the wheel rim
also has a high -sheen finish.

19-inch RS Spyder wheels with
central locking device.
Reminiscent of the classic
RS Spyder design, these forged
aluminium wheels with a
motorsport-derived central locking
device are available on request
for the 911 Turbo models and are
fit ted as standard to the new
911 Turbo S models. By reducing
rotating masses, they deliver
an even more agile driving expe -
rience. Benefiting from innovative
ongoing developments to the
engineering conventionally used
only in a racing environment, the
striking central locking devices
of fer ef fective protection against
corrosion and are easy to clean.
Alternatively, the 19 -inch
911 Turbo II wheels are available
for the 911 Turbo S models at no
extra cost.
Tyre Pressure Monitoring
(TPM).
Tyre Pressure Monitoring,
included as standard equipment,
warns against t yre pressure
loss. The driver is informed via
the on -board computer display.
The driver can check the pres -
sures of all four t yres from the
instrument cluster. Each time
the t yres are re-inflated, or when -
ever a wheel has been changed,
the updated t yre pressures are
displayed quickly – for increased
comfort and safet y.

Sport Chrono Package Turbo
with dynamic engine mount
system.
The Sport Chrono Package Turbo
with dynamic engine mount
system is standard on 911 Turbo S
models and available as an
option for 911 Turbo models.

This integrated system provides
simultaneous enhancement for
engine, chassis and transmission.
Key features include a digital
and analogue stopwatch on the
dashboard, a performance dis -
play, a personal memor y function
in the Porsche Communication
Management (PCM), the SPORT
but ton and – in combination with
PDK – the SPORT PLUS but ton,
and an additional display on the
steering wheel which informs the
driver if the SPORT but tons and Launch Control have been acti
-
vated. The 911 Turbo models
additionally of fer the ‘overboost ’
function. This is how it works:
When ‘Sport ’ mode is selected,
the engine management system
creates a much more aggressive
response to pedal inputs. To do
this, it implements an alternative
throt tle map which relates the
pedal position in the foot well to
a wider angle of opening in the
throt tle body. In higher gears, it
uses a hard rev- limiter to protect
the engine under power.
In the 911 Turbo models, under
full acceleration, the maximum
boost pressure in the lower and
medium speed ranges is now
temporarily increased by approx -
imately 0.2 bar. As a result,
engine torque is boosted by 50 Nm to a maximum of 700 Nm for a
limited period. (The 911 Turbo S
models are configured to operate
with a higher boost pressure level,

which means that their maximum
torque is always 700 Nm.)
In addition to the engine, ‘Sport ’
mode is enabled in the standard
Porsche Active Suspension
Management (PASM) suspension.
The dampers become firmer,
enabling faster turn - in as well as
bet ter contact with the road.
In automatic mode of PDK,
the basic gearshif t pat tern is
switched to high-performance
mode. The gear change action is
virtually instantaneous, while the
shift points are timed for maxi -
mum acceleration. Lif t of f the
throt tle – even at high revs – and
the system automatically shif ts
down to apply engine braking. In
manual shif t mode, gear chang -
ing is faster and more dynamic.
Porsche Stabilit y Management
(PSM) is also adapted, with the
intervention threshold raised. As
a result, the car has a more natu -
ral response to lateral and longi -
tudinal forces. Cornering agilit y
is greatly enhanced, when both braking to turn in and applying
power on exit – particularly

in low-speed bends. For even
greater driving pleasure.
For maximum manoeuvrabilit y,
PSM can be partially disabled
while the car is still in ‘Sport ’
mode. PSM simply monitors the
forces acting on the car and
will only intervene in the most
critical scenarios, e.g. when ABS
assistance is required on both
front wheels.
In conjunction with PDK (standard
on 911 Turbo S models), the
Sport Chrono Package Turbo with
dynamic engine mount system
has t wo additional functions that can be activated via the SPORT
PLUS but ton, for a sport y drive
that borders on a motorsport
experience.
The first function is ‘Launch
Control’, which, for example
when per forming laps, helps you
achieve optimum acceleration
from a standing start, a racing
start in other words.
The function works like this:
press the SPORT PLUS but ton
when the transmission is in ‘D’
or ‘M’. Then, with your lef t foot,
press the brake pedal and accel -
erate fully with the right foot.
The car recognises ‘Launch’ mode
from the accelerator kickdown action and adjusts the engine
speed to the optimum level,
which is around 5,000 rpm. At
the same time, boost pressure
is increased to approximately

0.5 bar, engine torque is
increased and the clutch is
applied lightly. ‘Launch Control’
now appears in the steering
wheel display. Now release the
brake as quickly as you can –
and feel the acceleration power
unleashed to the road.

The second function is the
‘motorsport-derived gearshift
strategy’. Using this, Porsche
Doppel
kupplung (PDK) is geared
up for the shortest possible
shif t times and optimum shif t
points for maximum acceleration
– ideal for the racetrack.
A key component of the Sport
Chrono Package Turbo with
dynamic engine mount system is
the stopwatch mounted on the
dashboard. Porsche Communica -
tion Management (PCM, page 86)
has a special performance display
to view, store and evaluate lap
times or other driving times. It
shows the total driving time, lap
distance, lap number and the
lap times recorded so far. You can
view the current fastest lap and
the remaining range until empt y.
Travelled distances can be
recorded and benchmark times
defined. The personal memory function of
the Sport Chrono Package Turbo
can also be used to store person
-
alised set tings for a range of
systems, including the orientation
lighting or air conditioning.
Operation of the dynamic
engine mount system.
Stiffness and softness as required.
That ’s the principle behind the
dynamic engine mount system
now being of fered for the first
time as part of the Sport Chrono
Package Turbo. Essentially, it ’s an
electronically controlled system
for controlling the stif fness of the
engine mounts.
The engine is bolted to the body
using t wo mounts and follows
New ton’s law of inertia, namely
that a body will continue to move
in a uniform straight line unless it is made to change its direction
by a force acting upon it.
Put more simply: when you are
driving into a bend, the vehicle will
follow your steering but, at first,
the mass of the engine won’t. This
means that the rear of the vehicle
is pushed out wards because of
the inert forces from the engine’s
mass acting on it.
The dynamic engine mount

system minimises this effect.
The steering angle longitudinal
and lateral acceleration values
are constantly recorded by
sensors and the stif fness of the
t wo engine mounts is changed
automatically according to the
driving st yle. This is achieved
using a magnetisable (magneto -
rheological) fluid and an electri -
cally generated magnetic field.
The magnetisable particles align
with each other and the fluid’s viscosit y changes. This alters the
stif fness and absorption of the
engine mounts: sof ter for greater
comfort and less vibration when
driving normally, harder for a
more direct driving feel when

driving more sportily.
The dynamic engine mount

system also reduces the vertical
oscillations of the engine when
accelerating under full load. The
result: greater and more uniform
force on the rear axle, increased
traction and bet ter acceleration.
All this means t wo things: percep -
tibly more stable handling under
load change conditions and in fast
corners and a step closer to the
ultimate sport y drive – combined
with enhanced levels of comfort.

Interior.
Efficient ergonomics is the guid-
ing theme for the interior. The
steering wheel of fers 40 mm of
adjustment for both height and
reach. A multifunction steering
wheel – with or without steering
wheel heating – is available on
request. The distinctively designed gear lever (for the six-
speed manual gearbox) and PDK
gear selector are easy to operate.
Porsche Communication Manage
-
ment (PCM) with a touchscreen is
fit ted as standard, as is the inte -
gral GPS navigation module with
hard drive navigation (page 86).
The new 911 Turbo S models come equipped with an integrated
six- disc CD/ DVD autochanger

and cruise control as standard.
The air- conditioning system with
an active carbon filter is fully
automatic. The leather finish on the seats,
dashboard, doors and rear
side panels is pleasing to the
touch. Available exclusively for
911 Turbo S models as standard
is the choice of t wo -tone leather
interior in either Black and Cream
or Black and Titanium Blue.
The centre console and door
storage compartments provide
storage space for personal items.
Below the passenger airbag are
t wo cup holders and below these
is the glove compartment with
CD storage.
Two 12-volt sockets (including the
cigaret te lighter) provide power
for a range of electrical devices.
Instruments.

The classic Porsche grouping of
five round instruments offers a
clear overview of all key informa -
tion.
The digital display in the centre-
left dial (speedometer) provides
main and trip odometer readings.
The central rev counter, featuring
the ‘turbo’ ‘or turbo S’ logo,
includes the standard on-board
computer display. This multi -
pur
pose field contains a perma -
nent digital speedometer as well
as the upshif t display on manual
models. The following optional information can also be displayed:
boost pressure, average speed,
average fuel consumption, t yre
pressure, current radio station,
navigation instructions and
remaining range till empt y. When
‘Sport ’ mode is selected on

the Sport Chrono Package Turbo
in a 911 Turbo model equipped
with dynamic engine mount
system, the temporary increase
in maximum torque is clearly
indicated by an arrow symbol in
the boost pressure display.
The third display, in the centre-
right dial, shows the time and
outside temperature.

Porsche Communication
Management (PCM).
Fit ted as standard, PCM is the
central information and commu -
nications system. It is both
multifunctional and very easy to
operate.
The main feature is the 6.5-inch
touchscreen for intuitive control.
For radio listeners, there is an
FM t win tuner with RDS, which
constantly scans for the best signal for the selected station,
and up to four radio aerials for
optimum reception.
The integrated single CD/ DVD
drive of the 911 Turbo models
can, in combination with the
standard BOSE
® Surround Sound
System, replay music from audio
and video DVDs in 5.1 Discrete
Surround Format. As an option,
a six-disc CD/ DVD autochanger
can also be integrated in PCM
(standard on 911 Turbo S
models). The standard GPS navigation
module has a hard drive with

map data for most European
countries. When viewing a map,
it is possible to select either a
3D perspective or a 2D display.
Electronic logbook.
The optional electronic logbook
enables automatic recording
of mileage, route distance, date
and time, starting point and
destination for each journey.
TV tuner.
A T V tuner, available as an option,
receives unencoded analogue
and digital television broadcasts
(DVB-T) to provide entertainment
bet ween journeys. For your
safet y, the T V picture cannot be
displayed while the vehicle is in
motion.
Voice control system.
Almost all of the functions of PCM
can be controlled via the optional
voice control system. The main
menu item is read aloud exactly
as it is displayed on the screen
and the voice control system
recognises commands or number
sequences, irrespective of the
speaker. It gives audible feedback
and guides you through the
functions. There is no need to
‘train’
the system. Phone book
entries can be retrieved, a radio
station selected or the navigation
destination entered directly by
speaking whole words.
Telephone module for PCM.*
The standard GSM telephone
module offers convenience and
excellent reception. By inserting
a SIM card directly into PCM’s
integral SIM card reader, calls
can be made using the hands-free
facilit y. For even more conven -
ience, the Bluetooth
® capabilit y
of a mobile phone can be used
to make calls via the SIM Access
Profile (SAP). Once automatic
pairing is complete, the mobile
phone’s aerial is switched of f to
conserve bat tery charge and the
phone operates via the car aerial.
Depending on the mobile phone
model, this gives access not only
to the numbers on the SIM card,
but also to the phone’s internal
memory. Depending on the phone,
it can also be controlled using
PCM, the optional multifunction
steering wheel or the optional
voice control system, without it
ever leaving your pocket.
In addition, the telephone module
enables you to establish a
Bluetooth
® link with those mobile
phones that only support the
Handsfree Profile (HFP). In this
case, the GSM connection is
always established through the
aerial of the mobile phone.
PCM acts as a hands-free system
and you can leave the mobile
phone tucked away. On request,
a cordless handset for the tele -
phone module is also available.
However, the handset cannot be
used for Bluetooth
® links estab -
lished using the Handsfree Profile
(HFP).
