| 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, there­
fore, 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
sport­
ier aerodynamics and the ride height low ­
ered 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 con ­
junction with the optional PDK, increase
traction and driving stability. Porsche
Dynamic Chassis Control (PDCC), the ac ­
tive roll stabilisation system, is available
as an option and improves agilit y, com ­
fort and safet y. 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 short ­
er braking distance. Bi ­Xenon headlights
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 injec ­
tion (DFI) and VarioCam Plus, which pro ­
duces 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 s e c o n d s 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 9 11 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 all ­wheel ­drive system, especially
when driving the car at the limits of per ­
formance. To achieve this, our engineers
have travelled right to the physical bound ­
aries – 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 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 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

3.8 ­litre 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. Fuel ­efficient 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.

Porsche Doppelkupplung (PDK).
Available as an option for all 911 Carrera
models is 7­speed PDK, featuring manu ­
al and automatic modes. It facili
tates
extremely fast gear changes
with no
interruption in the flow of power, whilst at
the same time improving acceleration
and fuel efficiency. In total, PDK has seven gears at its dis
­
posal. Gears 1 to 6 have a sports ratio
and top speed is reached in 6th gear.
7th
gear has a long ratio and helps to

reduce fuel consumption by keeping
engine revs low.
PDK is essentially t wo gearboxes in one
and thus requires t wo clutches. This
double ­clutch arrangement provides an
Porsche Doppelkupplung (PDK)
alternating, non ­positive connection
bet ween the t wo half gearboxes and the
engine by means of t wo separate input
shafts.
The flow of power from the engine is
transmit ted through one half gearbox and
one clutch at a time, while the next gear
is preselected in the second half gearbox. During a gear change, therefore, one
clutch simply opens and the other closes
at the same time, enabling gear changes
to take place within milliseconds.The effect is instant. Driving feels even
sportier and more dynamic, and agility

is increased. Depending on the gearshift
programme (SPORT button activated
Temperament | Transmission
or deactivated), the gear change is opti ­
mised for comfort or for sport y driving.
With the optional Sport Chrono Package,
PDK is enhanced by the ‘Launch Control’
and ‘motorsport ­derived gearshif t strategy’
functions (p. 67).
Coasting.
The ‘coasting’ function available with
Porsche Doppelkupplung (PDK) enables
you to save even more fuel where the
situation allows. The engine is decoupled
from the transmission to prevent deceler ­
ation caused by engine braking. In this
way, optimum use is made of the vehi ­
cle’s momentum, allowing it to coast for
longer distances.
For example, you may want to slow down
from 62 mph to 49 mph in anticipation
of the change of speed limit ahead. As
soon as you release the accelerator
pedal, PDK deselects the current gear auto
matically and you begin to coast
in neutral until you have reached your
desired speed. The moment you engage
the accelerator or brake pedal, PDK
selects the appropriate gear smoothly
and seamlessly within a fraction of a
second. In short, driving in coasting mode makes
a real impact on fuel consumption without
any need for compromise on comfort or
sporty performance.
Another way to reduce fuel consumption is
to utilise the coasting function on downhill
gradients that are gentle enough for you

to maintain a constant speed. Efficient on
long journeys, such as on the motorway,
PDK remains ready to respond as swiftly
and precisely as you would expect.

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.

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.

PTV in conjunction with the manual gear­
box, or PT V Plus with Porsche Doppel ­
kupplung (PDK), are available as options
for the 911 Carrera models and standard
in the 9 11 Carrera 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
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 stability. With PTV, the differential
lock is regulated mechanically; with

Porsche Torque Vectoring (PTV) and
Porsche Torque Vectoring Plus (PTV Plus).
PT V Plus, it is regulated electronically and
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
and turn.
