2014 PORSCHE 911 four wheel drive

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?

Switchbacks, hairpins, zigzags, S-bends...
There are countless reasons for having intelligent all-wheel drive.

The 911 Carrera 4S.
Steadfastness. Another apparent Porsche
contradiction. But whilst it ’s true that
sports cars are all about movement,
about surging forwards, it ’s even more
important to stay calm at all times,

to act with composure and never rashly.
So it ’s reassuring that you can rely

on the handling characteristics of the
911 Carrera 4S.
The Porsche Traction Management

(PTM) active all-wheel- drive system is
particularly dependable, especially

when driving the car at the limits of
performance. To achieve this, our
engineers have travelled right to the
physical boundaries – and extended

them. PTM now ensures that the car is poised and balanced, and really comes
into its own when adopting a sport y
driving st yle or travelling in extreme
weather conditions.
At the rear, the car is the personification
of roadholding, with its 44 mm wider
body and broader track by comparison
with the rear-wheel- drive 911 Carrera
models, and with road-hugging 305 mm
wide rear wheels. The seamless
horizontal taillight strip continues the
same st yling language. The all-wheel-
drive model is also recognisable from

the front, thanks to its dynamically
accentuated cooling air intakes in the
front end.
Though the car is practically at one with
the ground, it cannot keep still. This is
unsurprising when it is powered by a

3.8-litre engine developing 294 kW
(400 hp) at 7,400 rpm. When combined
with optional Porsche Doppelkupplung
(PDK), this power unit can accelerate the
car to 100 km/ h in a mere 4.3 seconds.
And continue up to a maximum speed of
297 km/ h.
Nevertheless, the 911 Carrera 4S
demonstrates that this level of
performance needn’t come at the
expense of fuel consumption and CO2
emissions. Fuel-efficient technologies,
such as electrical system recuperation,

2 emissions and efficiency class, please refer to pages 141/143.

auto start/stop – both integrated as
standard – and the ‘coasting’ function of
PDK, prove that Porsche is continually
resolving conflicting aims by means of
Intelligent Performance.
Where safety is concerned, the mono -
bloc fixed brake calipers at the front of
the S models have six pistons instead
of four, whilst the brake pads are 10 %
larger. The result is even shorter braking
distances. Proof that, at Porsche, safet y
is an integral part of performance, not its
polar opposite.
Steadfast through and through.
Corner after corner.

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.

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.

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.

a display above the airbag module
to inform you whether the SPORT,
SPORT PLUS and Launch Control
functions have been activated.
In conjunction with PDK, the steering
wheel features t wo gearshift paddles.
These are made from a strong alloy and
are ergonomically located behind the
left- and right -hand steering wheel
spokes. Pull the right
-hand paddle and
PDK shifts up. Pull the left-hand paddle and PDK shifts down. When PDK has
been combined with the optional Sport
Chrono Package, the left-

Sports seats.
The Sports seats in partial leather are
comfortable and provide support even
during performance driving. They are
equipped as standard with electric seat
height and backrest adjustment and
mechanical fore/aft adjustment.
Fully electric Sports seats.
If you don’t want to sacrifice sportiness
for comfort, the optional fully electric
Sports seats offer electric adjustment
of seat height, backrest angle, squab
angle, squab depth, fore/aft position,
four-way lumbar support and even the
steering column.
The integrated memory package
supports the exterior mirrors and all seat
positions on the driver’s side as well as,
for example, the set tings for the steering
wheel, lights, wipers, air conditioning,
door locks, optional PCM, and instrument
c l u s t e r.
Sports seats Plus.
Available as an option are Sports seats
Plus in leather with electric seat height
and backrest adjustment as well as
mechanical fore/aft adjustment. The side
bolsters on the squab and backrest
have firmer, sportier padding and offer
even better lateral support.

Seating.Sports bucket seats.1)
Sports bucket seats featuring a folding
backrest, integral thorax airbag and
manual fore/aft adjustment are available
as optional equipment. The seat shells
are made from glass and carbon-fibre
reinforced plastic (CFRP) with a carbon
surface finish.
Seat heating and ventilation.
Seat heating is available as an option for
all seats. Seats are heated in the squab,
the backrest and, for the front seats, the
side bolsters.
In conjunction with seat heating, we
can equip the seats (except for the
Sports bucket seats) with seat ventilation
on request. A slipstream effect is
pro duced by active ventilation of the
perfo
rated seat centre and backrest

and by passive aeration at the side
bolsters. This evaporates perspiration moisture and therefore makes for a dry
and pleas
ant seating environment, even
in hot weather.
Rear seats.
The rear seats are remarkably
comfortable for a sports car and the
shelf behind offers additional storage
space. With the backrests folded down,
the luggage compartment volume in
the 911 Carrera Coupé models increases
to 260 litres and, with a capacit y of
160 litres, the 911 Carrera Cabriolet
models offer plent y of space for luggage,
too.
Child seats.1)
ISOFIX child seat preparation including
top tether is available on the rear seats
as standard. On request, we can equip
the front passenger seat with ISOFIX child
seat preparation and integrate an airbag
deactivation feature.
