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

The new 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 con­
cerned, we call this Porsche identit y.
The immense power that is embodied in
this strong identit y is immediately apparent
in the new all ­wheel ­drive 911 Carrera 4.
Its enhanced Porsche Traction Management
(PTM) converts power directly into motion.
Not in a heav y ­handed way, but intelligently.
Sensors control 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 even more poised
and balanced handling during performance
driving, PTM quickly and clearly
demon ­
strates, especially in the wet and snow,
what we at Porsche understand by traction.
Expressed in simple terms, the new
911 Carrera 4 is self ­assured. An assured ­
ness that has been assisted by engineer ­
ing 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 t yres, the special air intakes, the illuminated rear light strip
with taillights and parking light function,
and distinctive sideskirts.
One of its inherent strengths is, of course,
its engine: the 3.4 ­litre flat ­six power unit
delivers 257 kW (350 hp) at 7,400 rpm
and accelerates the new 911 Carrera 4
from 0 to 62 mph in just 4.9 seconds.
Top speed is 177 mph. One strength may
possibly come as a surprise: by
downsiz­
ing the engine, it has been possible to
reduce the fuel consumption and CO
2
emissions by up to 15 % compared with
the previous model.
For fuel consumption and CO
2 emissions, please refer to pages 143/145.
Strength | The new 911 Carrera 4
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 new
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 multi­hole
injectors have been optimised for torque,
power output, fuel consumption, emissions
and ef ficient 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. vailing conditions. 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 catalytic 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 mix
­
ture 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 emis ­
sions are monitored by the Lambda
sensors.

| Transmission
It is possible to have a lot of power and
yet not be able to move any thing. Only
by using your power intelligently will you
truly progress – and with consummate
ease.
Enhanced 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.

| Chassis and body
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. Sensors record the body movements

that accompany powerful acceleration,
braking or uneven road surfaces. In the
911, the number of sensors has been
increased for improved data acquisition
and even more ef ficient control interven­
tions. 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 between
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 stability
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 (PTV) 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 19­inch 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 20­inch 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).
Tyre Pressure Monitoring (TPM) is avail­
able on request. This safet y system 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 differential
(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 st yle.
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 ele ­
ments 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 pro ­
tection 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 the most poorly sur ­
faced roads.
Increased protection is provided by an
automatically deploying roll ­over protec ­
tion system if the car were to overturn.
t wo spring­loaded 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 auto ­
matic climate control as standard with
an enhanced ventilation effect and sepa ­
rate 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 18–149 mph
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 ­of f timer
keeps the daytime 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.
Park Assist is fit ted as standard in the
911 Carrera Cabriolet models and is
available as an option for the 911 Carrera
Coupé models. Featuring four inconspicu­
ous sensors in the rear end, the system
audibly alerts the driver to the presence
of obstacles detected behind the vehicle.
An intermittent warning tone increases in
rapidit y as the obstacle is approached.
The two
­position net ­type 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.
An enhanced version of Park Assist, with
four sensors in the front end, is available
as an option. The audible alert is supple
­
mented by a visual warning in the central
display screen, which shows a graphical
representation of the vehicle from over ­
head.
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 wind
­
screen wipers, is available as an option.
Slide/tilt sunroof.
The electrically adjustable slide/tilt sun ­
roof is available as optional equipment
for all 911 Carrera models. It opens out ­
wards so that it does not interfere with
headroom. Another advantage of the
novel design is the large aperture for
increased driving pleasure under the
open sky.

from Porsche Tequipment. The system
makes it possible to locate a stolen
vehicle across most of the countries
of Europe. The preparation package
includes a special wiring loom and a

tilt sensor for the alarm system.
Luggage compartment.
The luggage compartment volume in the
911 models is 145 litres – 125 litres on
the 911 Carrera all ­wheel ­drive models.
The luggage compartment is fully trimmed
in scratch ­resistant materials.
Roof transport system.
Available as an option for the Coupé
models, the roof transport system in
aluminium is aerodynamically efficient,
very light weight and easy to fit. A range
of at tachments is available, such as a
roof box, a bike carrier or a ski/snowboard
carrier. Maximum roof load is 75 kg.
Porsche Entry & Drive.
With the optional Porsche Entry & Drive,
you can leave your car key in your pocket.
As soon as you grab the door handle
or approach the luggage compartment,
