| The 911 Carrera S
Its identity emerged on the racetrack.
Its home is on the road.

The 911 Carrera S.
Nothing defines us more than our heritage.
It says a lot about who we are. This is
particularly true of the 9 11 Carrera S,
which has all the characteristics you would
expect of a sports car whose origin is
in motorsport.
An elementary component of its DNA,
therefore, is power in the form of a 3.8 ­litre
engine with direct fuel injection (DFI) and
VarioCam Plus. It delivers 294 kW (400 hp)
at 7,400 rpm, and the maximum torque
of 440 Nm is achieved at 5,600 rpm. In
conjunction with the manual gearbox, the
sprint from 0 to 62 mph is completed in
just 4.5 seconds. Top speed isn’t reached
until 188 mph.
On figures alone, the 9 11 Carrera S
excels, particularly in terms of efficiency.
Fuel consumption and CO
2 emissions
have been reduced by 15 % compared
with the previous model. This has been
possible thanks to the auto start/stop
function, which is available as standard,
and the coasting function in conjunction
with the optional Porsche Doppelkupp­
lung (PDK).
It ’s not difficult to tell where the
911 Carrera S comes from. You can hear
it in the resonant engine sound and you
can see it in the t win tailpipes in brushed
stainless steel and 20 ­inch Carrera S
wheels. You can also feel it, thanks to Porsche
Active Suspension Management (PASM), which is fit ted as standard, or the optional
PASM sports suspension with even
sportier aerodynamics and the ride height
lowered by 20 mm. Or the optional
Sport Chrono Package and dynamic
engine mounts. Available as standard,
Porsche Torque Vectoring (PTV), or
Porsche Torque Vectoring Plus (PTV Plus)
in conjunction with the optional PDK,
increase traction and driving stability.
Porsche Dynamic Chassis Control (PDCC),
the active roll stabilisation system, is
available as an option and improves
agility, comfort and safety. On the subject of safet y, the brakes at
the front of the 911 Carrera S come
equipped with monobloc fixed calipers
with six instead of four pistons for im
­
proved braking performance and a
shorter braking distance. Bi ­Xenon head ­
lights are standard and the Porsche
Dynamic Light System (PDLS) is available
as an option.
There is no doubt. The 9 11 Carrera S
knows its roots, and embraces them with
efficiency, power and sporty performance.

| The 911 Carrera S Cabriolet
Porsche 356, Porsche 550, Porsche Carrera GT:
openness has always been a Porsche tradition.

The 911 Carrera S Cabriolet.
Open ­top driving is integral to Porsche
history. It began back in 1948 with the
No. 1. The convertible variant of the
first 356 became a legend, as did its
descendent, the Porsche 550 Spyder.
In 1982, the first 911 Carrera model
in cabriolet form was introduced to the
road. Two things that all open ­top
Porsche cars have in common are an
urge for sport y acceleration and unlimited
driving pleasure. The time has come to
carry this tradition on into the future.
The 911 Carrera S Cabriolet does just
that. That explains what motivates us, and

this describes what drives the car: the
3.8 ­litre engine with direct fuel injection
(DFI) and VarioCam Plus, which produces
294 kW (400 hp) at 7,400 rpm. The
911 Carrera S Cabriolet completes
the sprint from 0 to 62 mph in just
4.7 seconds and reaches a top speed
of 187 mph.
These are impressive performance
figures, founded on the principle that, if
you want to keep moving, you shouldn’t
carry unnecessary weight. This is pre ­
cisely why the 911 Carrera S Cabriolet
incorporates extensive use of lightweight
materials.
The hood has a crucial role in this respect.
On the 911, the hood has been funda­
mentally revised. Integrated magnesium
elements make the hood light yet extremely
robust. The hood opens and closes in
only 13 seconds and is operable up to a
speed of 31 mph. With the hood closed,
the car’s profile is optimised for aerody ­
namic performance, which explains the
low drag coefficient of 0.30. Wind noise
is practically eliminated.
The integrated wind deflector manipulates
headwind to create ideal conditions.
Electrically powered and installed directly
behind the passenger cell, it provides
effective protection against air turbulence.
Twin tailpipes in stainless steel also
make a clear statement. The 20 ­inch
Carrera S wheels afford an unobstructed
glimpse of the brake calipers with a
red painted finish. As you would expect,
the 911 Cabriolet offers a high level of
occupant safet y and features an effective
roll ­over protection concept as well as
full ­size airbags for the driver and front
p a s s e n g e r.
Without question, the 911 Carrera S
Cabriolet has remained faithful to the
sporty spirit of its predecessors and is
ensuring that the legacy lives on in the
21s t ce n t u r y.

Switchbacks, hairpins, zigzags, S-bends...
There are countless reasons for having intelligent all-wheel drive.
The new 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 impor­
tant to stay calm at all times, to act with
composure and never rashly. So it ’s re ­
assuring that you can rely on the handling
characteristics of the new 911 Carrera 4S.
Particularly dependable is the enhanced
Porsche Traction Management (PTM)
active all­wheel­drive system, especially
when driving the car at the limits of per­
formance. To achieve this, our engineers
have travelled right to the physical
boundaries – and extended them.
PTM now ensures that the car is even
more 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 road holding, with its 44 mm wider
body, wider track and road­hugging
305 mm wide rear wheels. The seamless
horizontal taillight strip continues the
same st yling language. The all­wheel­
drive model is also recognisable from the
front thanks to its dynamically accentuat­
ed 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
3.8­litre engine developing 294 kW
(400 hp) at 7,400 rpm. When combined
with Porsche Doppelkupplung (PDK),
this power unit can accelerate the car to
62 mph in just 4.3 seconds. And contin­
ue up to a maximum speed of 184 mph.
This hasn’t come at the expense of fuel
consumption and CO
2 emissions either.
Figures for the new 911 Carrera 4S are
up to 13 % lower than those of its prede­
cessor. Fuel­efficient technologies, such
as electrical system recuperation, auto
start /stop – both fit ted as standard – and
the ‘coasting’ function of PDK, prove that
Porsche is continually resolving conflict­
ing aims through Intelligent Performance.
Where safety is concerned, the mono­
bloc fixed brake calipers at the front
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.

A widely held belief about motorsport is
that power is the only thing that mat ters.
From experience, we know bet ter. Extra
horsepower alone has never been enough
to win a single race. Much more important
to us are ideas – ideas that inspire more
intelligent vehicle concepts and more
ef ficient drive systems. The same applies
on the road. It ’s about get ting the most
out of what you’ve got.
Auto start/stop function.
The auto start/stop function is standard
in the 911 Carrera models.
In cars with the manual gearbox, the
engine switches off automatically when,
for example, you stop at traffic lights,
select neutral and release the clutch
pedal. In cars with Porsche Doppelkupplung
(PDK), the engine switches off whenever
you stop and leave your foot on the
brake pedal.
All audio and communication systems
remain switched on and the climate con ­
trol continues to maintain your selected
temperature. The only differences you
will notice are the silence at the rear and
the fuel saving. As soon as you operate
the clutch or release the brake, the
engine will restart swiftly and smoothly. The auto start/stop function may remain
inactive under particular circumstances,
for example: extreme outside tempera
­
tures, when the SPORT but ton is selected
or if bat tery charge is low. It is also pos ­
sible to deactivate the function manually
using a separate but ton on the centre
console.
Thermal management.
The thermal management system
regulates the temperature in the engine
and gearbox through the intelligent
manipulation of heat flow.
In this way, the engine and gearbox reach
their optimum operating temperature
sooner. As a result, fuel consumption is
reduced through increased combustion
efficiency and lubrication performance.

Electrical system recuperation.
The 911 Carrera models are also equipped
as standard with fuel ­saving electrical
system recuperation technology. The
vehicle bat tery is recharged by the alter ­
nator, predominantly under braking.
Under acceleration, on the other hand,
the power draw of the alternator is limited
to increase the engine output available
for driving. The electrical systems are
supplied by the electrical energy stored
during the recharging process.

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.

Control, discipline, precision.

At Porsche, we take driving pleasure very seriously.

S a f e t y.
Brakes.
Another crucial piece of the Porsche
identit y is the brakes. We value them as
highly as we do our engines and chassis.
They set standards for deceleration and
stabilit y, and give the driver the reassur ­
ance needed to push the car to the limits
of its performance.
The 911 Carrera base models are fit ted
front and rear with anodised black four ­
piston aluminium monobloc fixed calipers.
All brake discs have a diameter of 330 mm.
On the S models, we have fit ted larger
brakes and more brake pistons to cope
with the higher engine power of these
models. Consequently, they feature red
six­piston monobloc aluminium fixed
brake calipers at the front and four ­piston
aluminium monobloc fixed calipers at
the rear. The brake disc diameter is
340 mm at the front and 330 mm at the
rear. The results are enhanced braking
performance and stability.
On all models, the brake calipers have
an enclosed monobloc construction.
This makes them tougher but lighter and enables a more rapid response and
release of the brake even under extreme
loads. The pedal travel is short and

the biting point precise. The brake discs
are cross ­drilled for better performance
in the wet.
Other benefits of the standard braking
system include the anti ­lock braking
system (ABS), designed to keep deceler ­
ation constant. Pedal effort is reduced
and braking response improved by an
8 ­/9 ­inch tandem vacuum brake booster.
In the S models, brake disc cooling is
further enhanced by modified air spoilers.

From the start, Porsche has been
synonymous with motorsport. Ever since
1948, when we found our identit y on
the racetrack, we have taken the experi ­
ence we have gained and applied it to
the road. The optional Porsche Ceramic
Composite Brake (PCCB) is a fine example.
This brake system has already had to
cope with the harshest requirements of
Composure | Safet y
motor racing and is fit ted in cars that
compete in demanding events such as
the Porsche Mobil 1 Supercup.
The cross ­drilled PCCB ceramic brake
discs for the 911 Carrera have a diame ­
ter of 350 mm front and rear for even
more formidable braking performance. What we’ve discovered from over 30,000 racing victories:
Brake later, finish sooner.

Porsche Ceramic Composite Brake (PCCB).The use of six ­piston aluminium monobloc
brake calipers on the front axle and four ­
piston units at the rear – all finished in
yellow – ensures extremely high brake
forces which, crucially, are exceptionally
consistent.
PCCB enables shorter braking distances
in even the toughest road and race
conditions. Excellent fade resistance
ensures greater balance when slowing
from racetrack speeds.
The key advantage of PCCB is the
extremely low weight of the ceramic
brake discs, which are approximately
50 % lighter than standard discs of similar
design and size. As well as enhancing performance and fuel economy, this

represents a major reduction in unsprung
and rotating masses. The consequence
of this is bet ter road holding and
increased comfort, particularly on uneven
roads, as well as greater agilit y and
improved handling.
Please note that circuit racing, track
day use and other forms of performance
driving can significantly reduce the
service life of even the most durable
brake pads and discs.
As with conventional high ­performance
braking systems, we recommend that
all brake components be professionally
inspected and replaced where necessary
after every track event.

2 emissions, please refer to pages 139/141.

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 far sooner and
with considerably 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.
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.

The 911 Carrera models are equipped

as standard with Bi ­Xenon headlights
including a headlight cleaning system
and dynamic range control. With dipped
or main beam, the road ahead is
illuminated more uniformly.
The LED front light units incorporate
direction indicators, daytime running
lights and position lights.
Automatic headlight activation is also
included as standard. The moment it gets
dark, the daytime running lights switch
off and the dipped beam headlights
switch on automatically.
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 adaptive LED brake lights
begin to pulsate. If the vehicle is braked
to a halt, the hazard warning lights will switch on automatically, alerting following
traffic more quickly to a critical situation.
The lighting system features an automa­
tic
switch
­off and the ‘Welcome Home’
function. It ’s good to know what ’s around
the next corner or on the way to your
front door.
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.

automatically in t wo stages. Stage 1 is
the basic position for driving in cit y traffic,
for example. Stage 2 is designed for
driving at faster speeds, such as on the
motorway. Above 80 mph, the range
is adapted again.
Another feature of PDLS is the adverse

rear fog light is switched on. It reduces
the effect of reflection phenomena in
poor visibilit y conditions to avoid the risk
of the driver being dazzled.

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.
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.
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.
Adaptive cruise control with Porsche
Active Safe (PAS).
1)
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 gently applying the brakes, until
the distance 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.
