When you know your strengths,
it’s easy to acquire new ones.

The 911 Carrera 4.
One thing is for certain. When it comes to
finding your own strengths, it always
helps to know who you are and where you
come from. Where the 911 is concerned,
we call this Porsche Identit y.
The immense power that is embodied
in this strong identit y is immediately
apparent in the all-wheel-drive
911 Carrera 4. Its Porsche Traction
Management (PTM) converts power
directly into motion. Not in a heav y-
handed way, but intelligently. Among
other variables, sensors monitor the
rotational speeds of all four wheels,
the vehicle’s lateral and longitudinal acceleration and the steering angle. In
this way, the active all-wheel drive can
continually respond to different driving
situations and precisely distribute drive
forces bet ween the front and rear axles.
Tuned to provide poised and balanced
handling during performance driving,
PTM quickly and clearly demonstrates,
especially in the wet and snow, what

we at Porsche understand by traction.
Expressed in simple terms, the
911 Carrera 4 is self-assured. An
assuredness that has been assisted by
engineering and aesthetic details
such as the wider body – the rear wings are 44 mm wider than those of the

911 Carrera – the 295 mm wide rear
tyres, the special air intakes, the
illuminated rear light strip with taillights
and parking light function, and distinctive
side skirts.
One of its inherent strengths is, of course,
its engine: the 3.4-litre, six-cylinder
horizontally opposed power unit delivers
257 kW (350 hp) at 7,400 rpm and
accelerates the 911 Carrera 4 from

0 to 100 km/ h in just 4.9 seconds. Top
speed is 285 km/ h.

Let ’s now bring the power of identit y
to bear on the road. With the aid of the
7-speed manual transmission or the
optional PDK.
Both feature sports ratios
for gears 1 to 6 and a long-ratio 7th
gear for fuel efficiency.
The 911 has many strengths. The
911 Carrera 4, with its superlative
traction, dynamic performance and
safet y, has acquired even more.

Why not take your seat behind the wheel
and make these strengths your own?

DFI delivers fuel directly into the combustion
chamber with millisecond precision. The
spray and cone angles of the multi -hole
injectors have been optimised for torque,
power output, fuel consumption, emissions
and efficient combustion.
With direct injection, the engine manage -
ment system regulates injection timing
individually for each cylinder as well as
the injection rate for each cylinder bank.
This improves the combustion process
and fuel economy.
This results in instant acceleration,
extremely smooth running and an
extraordinary level of tractive power,
but with a comparatively low level of
fuel consumption.

For faster heating of the cataly tic converters
after a cold start and optimum torque in
the upper load range, up to three injection
pulses take place per combustion cycle.
DFI improves the internal cooling of
the combustion chamber by having the
mixture prepared directly in the cylinder.
This allows for a higher compression
ratio, which helps to deliver more output
at the same time as enhanced engine
efficiency. Injection is regulated by the
electronic engine management system
and emissions are monitored by the
Lambda sensors.

VarioCam Plus.
VarioCam Plus is a two- in
-one engine
concept for adjusting the intake
camshafts and switching the lift of the
intake valves.
The system first differentiates bet ween
driver inputs that typify normal,
everyday driving and those inputs
that demand maximum performance.
The electronic engine management
system then seamlessly adapts valve
operation to the prevailing conditions.

It is possible to have a lot of power yet not
be able to use it. Only by using your power
intelligently will you truly progress – and
with consummate ease.
Porsche Traction
Management (PTM) is
standard on all 911 Carrera all-wheel-drive
models. It is an active all-wheel- drive
system with an electronically variable
map-controlled multi-plate clutch,
automatic brake differential (ABD) and
anti-slip regulation (ASR). Drive power is distributed bet ween the
permanently driven rear axle and the
front axle by means of the electronically
variable multi
-plate clutch.
The status of the vehicle is continuously
monitored so that it is possible to respond
to different driving situations. Sensors
are used to collect a range of data, includ -
ing the rotational speed of all four wheels,
the lateral and longitudinal acceleration
of the car and the current steering angle. If, for example, the rear wheels begin
to lose traction under acceleration, a
greater proportion of the drive power
is automatically transmit ted to the front
axle by a more positive engagement of
the multi-
plate clutch. In addition, ASR
prevents wheel spin by adapting the
engine’s power output. During cornering,
the optimal level of drive power is
dis
tributed to the front wheels to ensure
excellent lateral stability. In conjunction with Porsche Stability
Management (PSM), PTM helps to ensure
the perfect distribution of drive power for
optimum traction in most road scenarios,
whether on long straights, through tight
corners, or on surfaces with different
friction coefficients.
Far better than a power struggle
is power interplay.

PASM, the electronic damping control
system, is standard in the 911 Carrera S
models and available as an option for
the 911 Carrera models. It actively and
continuously regulates damping forces
according to driving st yle and road
conditions. In addition, the suspension
is lowered by 10 mm.
PASM has t wo modes, which can be
selected using a separate but ton on
the centre console: ‘Normal’, which is a
blend of performance and comfort, and
‘Sport ’ where the setup is much firmer. To ensure efficient control interventions,
a multitude of sensors in the 911 record
the body movements that accompany
powerful acceleration, braking or uneven
road surfaces. The PASM control unit
evaluates the driving conditions and
modifies the damping force on each of
the wheels in accordance with the
selected mode.
In ‘Sport ’ mode, the suspension is set to
a harder damper rating. On uneven roads,
PASM immediately switches to a softer
rating, thereby improving contact bet ween the wheels and the road.

When the road surface improves, PASM
automatically reverts to the original,
harder rating. If ‘Normal’ mode is selected
and the driver’s st yle becomes more
assertive, PASM automatically switches
to a harder rating. Damping firms up,
and driving stabilit y and road safet y are
increased.
The results are tangible: increased
driving stability, improved comfort and
enhanced performance.
No need to let the laws of physics
spoil your fun.

Porsche Active Suspension Management (PASM).PASM sports suspension.
The PASM sports suspension is available
as an option for the 911 Carrera Coupé
models in conjunction with 20-inch
wheels and Porsche Torque Vectoring
(PT V) or Porsche Torque Vectoring Plus
(PTV Plus). The ride height is 20 mm lower than

with the standard suspension or 10 mm
compared with the PASM suspension.
The springs are harder and shorter, and
the anti-roll bars on the front and rear
axles are stiffer. The front spoiler lip has
a more sport y geometry, the rear spoiler
extends even further. These not only further reduce lift at the front axle, but
also provide downforce at the rear axle
for improved aerodynamics and even

better performance.

Wheels.
The 911 Carrera models are equipped
with 19-inch Carrera wheels as standard.
These are light weight alloys featuring a
classic sport y design. Tyre sizes are
235/40 ZR 19 and 285/35 ZR 19 at the
front and rear, respectively. All-wheel-
drive models are fit ted with even wider
295/35 ZR 19 t yres at the rear.The S models are equipped with light-
alloy 20 -inch Carrera
S wheels as
standard. The visual effect is sport y and
dynamic. The t yres are slightly wider to
cope with the increased power output of
these models: 245/35 ZR 20 at the
front, 295/30 ZR 20 at the rear. All-
wheel-drive models have 305/30 ZR 20
t yres at the rear.
The large t yre size improves both ride
comfort and track performance. Rolling
resistance, dry braking distances and t yre
weight are all comparatively low, thereby
helping to reduce fuel consumption.
A selection of 20 -inch wheels is available
in our range of options.
Tyre Pressure Monitoring (TPM).
Integrated as standard, Tyre Pressure
Monitoring (TPM) sends warnings to the
on-board computer’s display screen in
the event of low t yre pressure or a
gradual or sudden loss of pressure. The
individual pressures in all four t yres can
be displayed in the instrument cluster.
Porsche Stability Management (PSM).
As standard, the 911 Carrera models are
equipped with enhanced Porsche Stability
Management (PSM), which maintains sta -
bilit y even at the limits of dynamic driving
performance. Sensors continuously moni -
tor the direction, speed, yaw velocit y and
lateral acceleration of the car. Using this
information, PSM is able to calculate the actual direction of travel at any given
moment. If the car begins to oversteer or
understeer, PSM applies selective braking
on individual wheels to restore stabilit y.
Under acceleration on wet or low-grip
road surfaces, PSM improves traction
using the automatic brake diffe
rential
(ABD) and anti -slip regulation (ASR).
When the SPORT PLUS mode of the
optional Sport Chrono Package is selected,
the PSM threshold is raised to allow a
sportier driving style.
For an even more dynamic experience,
you always have the option to deactivate
PSM. It is automatically reactivated,
for your safet y, only if you brake harder
and either of the front wheels (in SPORT
PLUS mode, both of the front wheels) requires ABS assistance. ABS and ABD,
however, remain active at all times.
PSM therefore offers a high level of

driving stability and safety combined
with extraordinary agilit y. It ’s an
apparent contradiction in terms, but an
intrinsic part of the Porsche identit y.

Electric parking brake.
The electric parking brake, which you
can activate and deactivate manually,
releases automatically as you pull away.

With the hill-
hold function, you can
pull away without ever rolling back.
The system automatically detects when
the vehicle has come to a halt on an
uphill gradient requiring intervention.
PSM then maintains the brake pressure
at all four wheels to prevent the vehicle
from moving in the opposite direction.
Airbags.
The 911 Carrera models offer advanced
airbag technology in the form of full-size
driver and front passenger airbags, which
are inflated in t wo stages depending
on the severit y and t ype of accident (e.g.
frontal or offset frontal). In less serious
accidents, the airbags are only partially
inflated, thereby minimising discomfort
to the occupants. In addition to the central airbag control
unit on the transmission tunnel, a pair of
impact sensors are located near the
headlights. This allows a crash to be
detected and evaluated not just sooner,
but with even greater accuracy.
Porsche Side Impact Protection
System (POSIP).
Coupé or Cabriolet, the 911 models

are equipped as standard with the
Porsche Side Impact Protection System
(POSIP). It comprises side impact
protection elements in the doors and t wo airbags on each side. An integral
thorax airbag is located in each seat side
bolster, while the door panels each
contain an upwards-inflating head airbag.
Each thorax airbag has a volume of
10 litres and each head airbag 15 litres,
ensuring excellent protection in the event
of a side impact.
Cabriolet roll-over protection concept.
Despite their low weight, the 911 Carrera

Cabriolet models have exemplary
torsional rigidit y and flexural strength.
Body flexing is minimal even on irregular
road surfaces.
Increased protection is provided by
an automatically deploying roll-over
protection system if the car were to
overturn. Two spring-loaded roll-over
bars are neatly incorporated behind
the rear seats. The roll- over sensor
continuously monitors the car’s pitch
and roll, contact with the road, as
well as lateral and longitudinal forces.
If the car were to overturn, the roll- over
bars would be deployed instantly.

Climate control.
The 911 models feature t wo -zone
automatic climate control as standard
with an enhanced ventilation effect and
separate temperature controls for the
driver and front passenger. The available
air conditioning modes are gentle,
normal and strong.
An active carbon filter traps particles,
pollen and odours and an automatic
air-recirculation function permanently
monitors air quality, reduces humidity
and switches from fresh to recirculated
air when required. A demister function
keeps the windows clear in cold weather. In warmer weather, a solar sensor helps
the climate control
to detect strong
sunlight and automatically
compensate
for the comfort of both the driver and
front passenger.
HomeLink® (programmable garage
door opener).
As an option, it is possible to have
a programmable garage door opener
integrated into the overhead console.
At the push of a but ton, it controls up
to three different garage doors, lighting
systems or alarm systems.
Many things have practical qualities.
Even more have a sporty function.
And some are just extremely convenient.

Additional comfort and convenience features.
Cruise control.
This automatic speed control function is
available as an option. For greater driver
comfort on long stretches of road, cruise
control operates in the 30 –240 km/ h
speed range and is activated using a but -
ton on the steering column control stalk.

Light design package.
The optional light design package is both
practical and aesthetically appealing.
It comprises dimmable LEDs in the over -
head console and in the areas of the
door pulls, door storage compartments,
front foot wells and rear seats.
‘Welcome Home’ lighting.
For convenience, particularly at night,
the ‘Welcome Home’ lighting function
automatically switches on the LED day -
time running lights for a defined period
whenever the vehicle is opened or
closed using the key remote.
A customisable delayed switch- off timer
keeps the day time running lights, the
taillights and, where applicable, the
courtesy lights switched on until you
reach your front door.
Adaptive cruise control with Porsche
Active Safe (PAS).
Available as an option, this cruise control
function regulates your speed according
to the distance bet ween your vehicle and
the vehicle in front. A radar sensor moni -
tors the road ahead up to a distance of
200 m. If you have set a cruising speed
but have begun to gain on the vehicle in front because it is driving more slowly,
this is detected by the radar sensor.
The system now reduces the speed

of your vehicle at a maximum rate of
3.5 m/sec
2 by restricting the throt tle
or by applying the brakes appropriate
to the prevailing situation until the dis -
tance that you have preset is maintained.
Your vehicle will now continue at a reduced speed. If the other vehicle

decelerates further, adaptive cruise
control will continue to reduce your
cruising speed – even down to a halt. For additional safet y, if the system detects
that the distance from the vehicle in front
is decreasing, it will also prepare your
vehicle for braking by precharging the
braking system so that the brake pads are already in light contact with the
brake discs. However, drivers still have
to perform heavier braking themselves.
As soon as the road ahead clears again,
your vehicle will accelerate back up to
the cruising speed originally set.
If your vehicle approaches the vehicle
in front too quickly, Porsche Active Safe
(PAS) will issue audible and visual warn
-
ings. In addition, the system briefly jerks
the brakes and if necessary initiates
target braking, with any braking pressure
applied by the driver being increased
within certain system limits.

ParkAssist (front and rear).
An enhanced version of Park Assist, with
four sensors in the front end, is available
as an option. The audible alert is
supplemented by a visual warning in the
central display screen, which shows a
graphical representation of the vehicle
from overhead.
ParkAssist.
Park Assist is fit ted as standard in
t h e 911 Carrera Cabriolet models and
is available as an option for the
9 11 Carrera Coupé models. Featuring
four inconspicuous sensors in the rear
end, the system audibly alerts the driver
to the presence of obstacles detected
behind the vehicle. An intermit tent
warning tone increases in rapidity as the
obstacle is approached.
Reversing camera.
The optional reversing camera (only in
conjunction with ParkAssist (front and
rear), and with CDR Plus audio system or
PCM) facilitates precise reverse parking
and manoeuvring. Help is provided in the
form of the camera image and the
dynamic, superimposed guidelines on the
central display screen, which illustrate
the predicted course of the vehicle given
the current position of the steering
wheel.
Exterior mirrors and rear-view mirror.
Electrically adjustable exterior mirrors
are fitted as standard. Electrically folding
exterior mirrors with courtesy lighting
on both sides of the vehicle are available
as an option. By illuminating the area
in front of the doors, they make it easier
to find your way in the dark. An auto -
dimming function for the rear-view mirror
and exterior mirrors, with an integrated
rain sensor for the windscreen wipers,
is available as an option.
Slide/tilt sunroof.
The electrically adjustable slide/tilt
sunroof is available as an option for all
911 Carrera Coupé models. It opens
out wards so that it does not interfere
with headroom. Another advantage of
this special design is the large aperture
for increased driving pleasure under the
open sky. The t wo -position net-t ype wind
deflector protects against draught and
further reduces wind noise.
Glass slide/tilt sunroof.
The electrically adjustable slide/tilt sun -
roof is also available in tinted single -
glazed safet y glass. An integral electric
sunblind provides shade from unwanted
bright light. It is available in five different
colours. The design, headroom and aper -
ture of the glass roof are identical to
those of the regular slide/tilt sunroof. The
only difference is that, even when closed,
the glass sunroof still gives you that
open- to- the- sky feeling.

Digital radio.
The optional digital radio enables you to
receive digitally broadcast radio stations
and features a DAB t win tuner. It auto -
matically switches bet ween digital and
analogue to ensure optimum reception
of the selected station.
Telephone module.
The optional quadband GSM telephone
module offers convenience and excellent
reception. With a SIM inserted directly
into the integral SIM card reader of
CDR Plus or PCM, calls can be made
using the hands-free facilit y. For even
more convenience, the Bluetooth
®
capabilit y of a mobile phone can be used
to make calls via the SIM Access Profile
(SAP). Once the connection has been
established automatically, the mobile
phone’s aerial is switched off to conserve
battery 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 CDR Plus, PCM, the
optional multifunction steering wheel or
the optional voice control system, without
it ever leaving your pocket.
The telephone module also enables you to
establish a Bluetooth
® link with those
mobile phones that support only the
Handsfree Profile (HFP). In this case, the
GSM connection is always established
through the aerial of the mobile phone.
CDR Plus or PCM acts as a hands-free
system and you can leave the mobile
phone tucked away.
On request, a Bluetooth
® handset for the
telephone module is also available.
Stored in the centre console, it features
a display and keypad. However, the
handset cannot be used for Bluetooth
®
links established using the Handsfree
Profile (HFP).
Mobile phone preparation.
Mobile phone preparation is available
as an option so that a Bluetooth®
connection can be established with those
mobile phones that support only the
Handsfree Profile (HFP). This function
also enables you to leave your mobile
phone tucked away. The CDR audio
system, CDR Plus and PCM are able to
control only the basic functions of the
mobile phone. The GSM connection
is established through the aerial of the
mobile phone.
Voice control system.
If you require route guidance, need to
make a phone call or want to listen to the
radio, then why not just say so? Almost
all of the functions of PCM can be con -
trolled using the optional voice control
system with word -by
-word input. In the
majorit y of cases, you can simply say
the name of the menu item as seen on
1) TMC Pro is currently available in Germany, Austria and Switzerland.2) In MPEG -2 format.
The DVD-audio drive plays CDs and audio
DVDs and is MP3- compatible. Audio play -
back of video DVDs is also supported.
A six- disc CD/ DVD autochanger integrat -
ed into PCM is available as an option.
The universal audio interface (USB) in
the glove compartment enables you to
connect your iPod
® or any audio source.
Recharging is also supported. Once
connected, your iPod
® or USB stick is
then conveniently and safely operated
via the PCM, the optional multifunction
steering wheel or the optional voice
control system.
You can download the performance
display data from the Sport Chrono
Package and data from the electronic
logbook via the USB port. You can also
transfer up to 5,000 tracks (40 GB) in
MP3 format to the internal hard drive (or Jukebox) of PCM and play them from
there. Podcasts and audiobooks are
recognised and played and cover art is
displayed.
The navigation module in PCM features

a high-speed hard drive and allows you
to choose bet ween a 2D display and
a 3D perspective. In some regions, it is
possible to display the terrain (with an
overlaid satellite map) and buildings in
3D. Split screen mode enables you to
view t wo functions at once, such as the
current navigation map and a list of
symbols that represent the next driving
manoeuvre.
