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?

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.

“That can’t be done.”
If ever a sentence gave motivation to sports car designers, this is it.
Chassis and body.
A solid identit y tends to be described
with words like stability, directness or
substance. This might sound a lit tle
serious but, when it comes to the chassis
and body, we think that this is entirely
the right approach.
The best example is the engineered
design. Indeed, dynamic performance
and ride comfort fundamentally depend
on factors such as vehicle weight, body
rigidity, wheelbase, axle construction and
steering. With the 911, we challenged our
engineers to push the boundaries of what
is possible. Chassis control systems make a key
contribution to the 911 driving experience
and thus to the 911 identit y. These
include Porsche Stability Management
(PSM), Porsche Active Suspension
Management (PASM), which comes as
standard in the 911 Carrera S models,
Porsche Torque Vectoring (PT V) and
Porsche Torque Vectoring Plus (PT V Plus)

in conjunction with PDK. Porsche Dynamic
Chassis Control (PDCC) is additionally
available as an option for the 911 Carrera S
models.
Yet, there is still scope for improvement
as far as sport y performance is
concerned. The optional Sport Chrono
Package triggers an adrenaline rush at
the push of a but ton. Dynamic engine
mounts, until recently exclusively
reserved for 911
GT and Turbo models,
may not be capable of breaking the laws
of physics, but they do succeed in
exploiting them to their own advantage –
and yours.

With the optional Porsche Dynamic
Chassis Control (PDCC) for the S models
of the 911 Carrera, these characteristics
can be further accentuated: the vehicle
holds the road even bet ter and delivers
even sportier performance. PDCC is an active anti-
roll system that
suppresses lateral body movement during
cornering manoeuvres. In addition, it
minimises the lateral instability of the
vehicle on uneven ground. This effect is achieved with the aid of
hydraulic stabilising actuators in the form
of cylinders designed to optimise camber.
Lateral roll is counteracted by forces
generated at each individual wheel, based
on steering angle and lateral acceleration.
Rapid cornering in the 911 Carrera without PDCC (illustrative example) Rapid cornering in the 911 Carrera S with PDCC (illustrative example)
The results are improved dynamic
performance and increased ride comfort
at all speeds, as well as optimised turn-in
and stable load transfer characteristics.
In simple terms, the t yres and vehicle
hold the road bet ter and you can steer
through corners faster and in a more
relaxed manner.
PDCC sets standards for handling
performance, ride comfort and driving
pleasure. In the 911, your ‘usual’ way
suddenly becomes the Porsche way.

It ’s easy, and even makes sense, to carry
on in your usual way, but what happens
if a sudden change of direction leaves
you thrown off course? Then, it all comes
down to personal strength.
A Porsche has a clear sense of purpose
and is the embodiment of strength. It
demonstrates this with sport y and precise
handling and excellent roadholding.
You appreciate directness.
But love a few twists and turns.

SPORT button.
Fit ted as standard, the SPORT but ton
enables you to select a suspension setup
where the emphasis is on either comfort
or sport y performance. At the push of a
button, the electronic engine management
system switches the engine mapping to
offer an even sharper response and
engine dynamics that are more direct.
In vehicles with Porsche Doppelkupplung
(PDK), upshifts take place at higher
engine speeds and downshifts happen
sooner. In addition, coasting mode

and the auto start/stop function are
automatically deactivated. If fitted, the
optional sports exhaust system is also
activated automatically.
Sport Chrono Package.
The Sport Chrono Package including
dynamic engine mounts is available
as an option. This integrated system
provides simultaneous enhancement for
the chassis, engine and transmission.
Included in the package are a performance
display, a digital and an analogue stop -
watch and the SPORT PLUS but ton. An
additional display in the steering wheel
and instrument cluster indicates whether
the SPORT but tons and Launch Control
have been activated.
Every day can be sports day.

Additional performance enhancement systems.Electromechanical power steering.
Another possible definition of efficiency
is a system that works only when it is
needed, and then does so in a particularly
effective way.
This was the guiding principle for our
engineers in the development of the electromechanical power steering. Statis-

tics show that a car drives in a straight
line 90 % of the time. Unlike conventional
hydraulic pumps, the electric motor uses
energy only when the steering wheel is
actually turned. The absence of hydraulic
fluid also makes the system more
bene ficial to the environment.
As far as the other 10 % is concerned, we’re
optimally prepared as the steering system
is t ypically Porsche. It features a variable
steering ratio and responds sensitively
and directly at the same time as providing
customary agilit y, a high level of comfort
and precisely selected feedback from the
road. Our definition of efficient.
Power steering Plus.
Power steering Plus, the comfort-enhancing
power steering system, is available as an
option for the 911 Carrera models. At high
speeds, the steering is as firm as possible,
ensuring maximum precision whilst steer-
ing comfort remains as high. At low speeds,
the steering ratio of Power steering Plus
adjusts for much easier manoeuvring and
parking.

On activation of SPORT PLUS mode,
Porsche Active Suspension Management
(PASM) and, in the 911 Carrera S models,
optional Porsche Dynamic Chassis
Control (PDCC) switch to a harder
damping set ting and offer more direct
steering and, therefore, better
roadholding. In SPORT PLUS mode, the trigger
threshold for PSM is raised. Agilit y is
perceptibly enhanced when braking for
corners with PSM, allowing sportier
braking and exit acceleration. For even
greater dexterit y, PSM can be set to
standby while the car is still in
SPORT PLUS mode. For safet y, it is
set to intervene automatically only

when ABS assistance is required on both
the front wheels.
In combination with PDK, the Sport
Chrono Package has t wo additional
functions for a sport y drive that borders
on a motorsport experience. The first is ‘Launch Control’, which can be used

on the track to achieve the best
possible standing start – a racing start.
The second function is the ‘motorsport-
derived gearshift strategy’. Using this,
Porsche Doppelkupplung (PDK) is geared
up for extremely short shift times and optimum shift points for the maximum
acceleration available. This combination
of uncompromising and involving perfor-

mance is ideal for the racetrack.
A key component of the Sport Chrono
Package is the stopwatch mounted on
the dashboard. In conjunction with
optional PCM, a special performance
display enables you to view, store and
evaluate lap times or other driving times.
It shows the total driving time, lap
distance, lap number and lap times
recorded so far.
A feature of the Sport Chrono Package
borrowed from motorsport is the dynamic
engine mounts. These exploit the laws
of physics for your own driving pleasure.
Dynamic engine mounts.
You don’t have to take the 911 onto the
racetrack. But you can, more so than
ever, because dynamic engine mounts
are now included as part of the Sport
Chrono Package.
The electronically controlled system
minimises the oscillations and vibrations
of the entire drivetrain, especially
the engine, and combines the benefits
of a hard or soft engine mounting
arrangement.
A hard engine mounting delivers optimum
dynamic performance because it offers
the highest degree of handling precision
possible. Soft engine mounts, on the
other hand, minimise oscillations and
vibrations. While comfort is improved on
uneven road surfaces, this comes at
the expense of dynamic performance. Our engineers have solved this problem
by enabling the engine mounts to adapt
their stiffness and damping properties to
changes in driving st yle and road surface
conditions. This has been achieved by
use of a fluid with magnetic properties in
interaction with an electrically generated
field. For the driver, the results are tangi-

ble. Handling is perceptibly more stable
under load change conditions and in
fast corners. Whenever a less assertive
driving st yle is adopted, the dynamic
engine mounts provide a higher level of
comfor t.

PTV in conjunction with the manual
gearbox, or PT V Plus with Porsche
Doppelkupplung (PDK), are available as
options for the 911 Carrera models and
standard in the S models. Both systems
actively enhance vehicle dynamics and
stability. Operating in conjunction with a
mechanical (PT V) or electronic (PT V Plus)
rear differential lock, they work by
intelligently braking the rear wheels as
the situation demands.
As a function of steering angle and steering
speed, accelerator pedal position, yaw

rate and vehicle speed, PT V and PT V Plus

are able to improve steering response
and steering precision by specific braking
of the right or left rear wheel.
To be more precise, this means that when
the car is driven assertively into a corner,
moderate brake pressure is applied to the
inside rear wheel. Consequently, a greater
amount of drive force is distributed to the
outside rear wheel, inducing an additional
rotational pulse (yaw movement) around
the vehicle’s vertical axis. This results in
a direct and sport y steering action as the
car enters the corner.
At low and medium vehicle speeds, PT V
and PT V Plus significantly increase agilit y
and steering precision. At high speeds
and when accelerating out of corners,
the rear differential lock ensures greater
driving stabilit y. With PT V, the differential
lock is regulated mechanically; with

the torque distribution is infinitely varia ble.
Whichever system is fit ted, it interacts

with Porsche Stabilit y Management (PSM)
to improve driving stabilit y on a range
of surface conditions, including the wet
and snow.
For the driver, this means remarkable
stability, easier handling and outstanding
traction as well as greater agilit y at every
speed with precise steering and stable
load transfer characteristics. What else?
Unrivalled driving pleasure at every t wist

To see something coming, experience helps.
So does forward-looking technology.

Lights.
Composure | Safet y
The 911 Carrera models are equipped as
standard with Bi-Xenon headlights
including a headlight cleaning system
and dynamic range control. The LED
front light units incorporate indicators,
day time running lights and position
lights. Automatic headlight activation is
also included as standard.
Cut ting edge LED technology is also
used for the taillights, the high-level third
brake light, the licence plate illumination,
the rear direction indicators, the rear fog
light and – on all-wheel- drive models –
the rear light strip. LEDs provide bet ter
illumination and respond more quickly
to driver input.
In the event of sudden braking, the adap -
tive LED brake lights begin to pulsate.
If the vehicle is braked to a halt, the
hazard warning lights will switch on
automatically. The lighting system
fea tures an automatic switch-
off and

the ‘Welcome Home’ function.
Porsche Dynamic Light System (PDLS).
The Porsche Dynamic Light System
(PDLS) is available as an option. Its
dynamic cornering light function swivels
the headlights towards the inside of a
bend, based on steering angle and road
speed, in order to illuminate more of the
road at tight bends and turns. Put simply,
the road ahead is illuminated the moment
you enter a bend. Speed -sensitive head-
light range control is also part of the
PDLS as is the adverse weather function.
LED main headlights with Porsche
Dynamic Light System Plus (PDLS +
).

Superior safet y meets sport y design in
the form of the LED main headlights with
PDLS+ which are available as optional
equipment. Integrated into each headlight
housing are four LED spots for the
day time running lights, and one LED light
ring. In addition to being efficient and
long-lasting, LED technology also creates
a light very similar to daylight and thus
helps to reduce driver fatigue. One special feature of PDLS+ is the
dynamic main beam function. A camera
detects the lights of vehicles ahead
as well as those of oncoming traffic.
Based on the data from the camera, the
dynam
ic main beam function then adapts
the headlight range accordingly. This continu
ous, stepless control means that
you are able to see the course of the
road, pedestrians and potential hazards
earlier without hindering other road
users.

Our identity is found under the bonnet,
in the design and behind the steering wheel.

Comfort.
Driving a 911 is first and foremost
about the feel of the road in the original,
unadulterated and direct sense. Is it
possible, then, to mention the 911 and
comfort in the same breath? To speak
of systems that make driving ‘more
agreeable’, or of materials that feel
‘pleasant ’ to the touch? Good question.
In reality, however, should anyone really
be forced to choose one over the other?
Let ’s introduce ourselves to the concept
of sport y comfort – dynamic performance
that maintains composure even when
pushed to the extreme.
Interior.
Engineering and st yle – and Porsche
identit y on the inside, as demonstrated
by the ascending centre console. In
t ypical Porsche fashion, the use of form
follows a basic principle: focus on the
driver. This is why the distance bet ween
the gear lever or selector and steering
wheel is extremely short and the operat -
ing logic, such as that of the t wo -zone
air conditioning system or the suspension
settings, is clear and uncomplicated.
You shouldn’t have to browse one sub -
menu after another. You should instead
be able to concentrate on what ’s
important: the road. Our materials are high- qualit y with a
sporty character. The steering wheel rim,
door pulls and armrests are in leather,
for instance. Alcantara has proven its
worth in motorsport and is used as
standard for the roof lining of the Coupé
models.
In addition to the choice of Black,
Platinum Grey, Luxor Beige and Yachting
Blue for the interior, there is a wide

range of other personalisation options
available, including two-
tone colour
combinations or special colours and
materials such as carbon, aluminium
or high - qualit y wood.
