Many legends look to the past.
This one looks to the future.

T h e 9 11 .
It ’s time to look forward. Because,
traditionally, the 911 has always had
an eye to the future.
Our own engineering tradition is evident
from the ‘Dr. Ing.’ in our company name.
Also from our racing victories, now total ­
ling more than 30,000. Not just feats
of heroism any longer, but responsibilit y
for the future of the sports car and for
the environment. Then there is the 911’s
reputation as an iconic sports car. How­
ever, this reputation means nothing
unless we continue to breathe new life
into old ideas.
For us, heritage and future are inseparably
linked. Of course, we could simply
have made a capable sports car, but this
wouldn’t have been a Porsche, and
certainly not a 911.
Our identit y is the 911. This is especially
true, even in the 21st century. Instantly
recognisable and originally engineered
for the racetrack, it continues to stir the
emotions today, just as it did in 1963.
Yet, is that enough to move forward?
Above all, is it enough for you? Don’t we
need to break the stranglehold of tradi ­
tion once in a while before it one day
stifles innovation altogether? We believe that the answer is ‘yes’, which is why
almost every component in the latest

generation 911 is new. This is our approach to the preservation of tradition.
It is precisely how we respond to the
passion for the sports car and do justice
to the 911 legend, and always with
tomorrow in mind.
We have achieved this with a future ­
oriented design and a longer wheelbase,
with refined engines that consume less
fuel but deliver more power, with efficiency ­
enhancing technologies such as auto
start/stop, thermal management and
electrical system recuperation, with an
intelligent light weight body and a new hood concept on the Cabriolet models,
with the further enhanced Porsche Traction
Management (PTM) active all ­wheel drive,
and an interior that combines sophisticated
ergonomics and
sporty comfort.
All of that is what defines us. In short, it
is the way in which we combine tradition
and innovation, performance and everyday
practicality, form and function. For us,
these are not contradictions, but our moti ­
vation. We are referring to Intelligent
Performance.
Our identit y can be accurately described
by many words, and by one number.
The 911. Porsche identit y. Identit y is a combination of disposition,
personalit y and heritage. In our at tempt to
understand it, we tend to compare

differences.
This is equally true in the case of the
911 Carrera models. With defining
at tributes such as performance, efficiency,
st yle and comfort, they reveal a character
of their own and fulfil your individual
expectations – not just of any sports car,
but of a 911.

Can you imagine a face without an expression?

Exterior design.
Every child recognises a 911, but can its
identit y be described in words? It can, by
looking more closely at the use of form,
proportions and contours. The roof line
tapers down into the rear. The wings are
higher than the front lid and, at the rear,
they add muscle. They give the 911 its
distinctive expression and leave you in
no doubt as to its temperament.
The overall appearance is low, wide and
sleek. Typically 911.
So, is every thing just the same as it has
been since 1963? Yes, and no. After all, only those who change will remain true

to themselves – and we’ve changed.
Our designers and engineers speak
guardedly about the 911 evolution.
Meanwhile, they continually manage to
take great strides forward with innova ­
tions motivated by the principle that
these should be functional and perfectly
compatible. The result is a harmonious
overall concept that makes the 911 a
sports car fit for the 21st century.
Indeed, the Porsche 911 Carrera has
already won the prestigious ‘red dot
award: product design 2012’ for its
unique functional and emotive design. To show you what we mean, we should
start by looking at the car’s exterior.

The longer wheelbase of the 911 improves
driving stability and cornering dynamics.
Overhangs are short at the front and rear,
making the 911 look even more compact
and agile.
The sporty overall impression is emphasised
by the roof line, which is lower than that of
the previous model, and by the wider track
at the front
– 46 mm on the 911 Carrera
models and 52 mm on the 911 Carrera S
models. On the new Carrera all ­wheel ­drive
models, the body has also been widened
at the rear by 44 mm. Increased traction and agilit y are just some of the benefits
these refinements bring.
The silhouette is therefore typically 911
and t ypical in terms of its development,
which will now be described in more detail.

Interior design
Sporty ergonomics for ordinary driving.
Extraordinary comfort for sporty driving.

Interior design.
At Porsche, we don’t build everyday
sports cars, we build sports cars for
everyday use. How? By understanding
that great agilit y and maximum comfort
are not mutually exclusive but are, in
fact, aspects of a harmonious overall
concept.
This is especially true of the interior of
the 911. Sportiness, functionality and
high ­quality materials combine to form a
cohesive whole that is conducive to
dynamic driving, even during everyday
use. This becomes clearer the moment you
get in. The longer wheelbase
now of fers
25 mm more leg room in the front than
in previous 911 Carrera models, for
example.
Sportiness in harmony with comfort is
the theme which is reflected in the clever
ergonomics that characterise the entire
interior design. The materials used, the
layout of the controls and their operating
logic belong to a new generation of
sports car. Another new design for the
911 is the ascending centre console.
Its intelligent operating concept follows
a clear principle of direct simplicity. A classic 911 feature is the arrangement
of the five circular instruments with the
rev counter in the middle. The contempo
­
rary instrument cluster featuring a high ­
resolution 4.6 ­inch full VGA TFT colour
display enables the driver to view infor ­
mation from, for example, the new
adaptive cruise control function or the
all ­wheel ­drive display, or to see navi­
gation instructions.
Acoustics are an integral part of the
concept, particularly the engine sound.
Available as an option is the Burmester
®
High ­End Surround Sound System. Optimised for the 911 Carrera model
range, it features 12 loudspeakers and

a total output of 821 wat ts for a perfect
spatial sound.
The 911 proves that apparent opposites,
such as st yle and engineering or comfort
and performance, can go hand in hand.
For us, there is no contradiction and
certainly no need for compromise. After
all, a strong personalit y does not deny
the existence of opposites, it unites them.

Engineering
Let’s forget the future for a moment.
As we discover it in the present.

Engineering.
What use is the engineering of tomorrow
when it can be found on the road today?
None. So let ’s turn to the here and now.
The engines, as you would expect, are
characterised by six horizontally opposed
cylinders. The 3.4 ­litre engine in the
911 Carrera models produces 257 kW
(350 hp); in the 911 Carrera S models,
the 3.8 ­litre engine develops 294 kW
(400 hp). All variants are equipped with
direct fuel injection (DFI) and VarioCam
Plus for increased power and compara ­
tively low fuel consumption. Power is transmit ted to the wheels by the
7
­speed manual gearbox with the highest
gear designed specifically with fuel econ ­
omy in mind or, optionally, by efficiency ­
enhanced Porsche Doppel kupplung (PDK),
which offers gear changes with no inter ­
ruption in the flow of power.
On the 911 Carrera all ­wheel ­drive
models, the enhanced Porsche Traction
Management (PTM) distributes the power
to the wheels according to weather and
road conditions. Handling is even more
poised, particularly when the car is being
driven to its limits. As a result, you are
safer not just in the wet and snow, but
also when adopting a sport y driving st yle.
The chassis is also packed with forward ­
looking technology. Fitted as standard
in the 911 Carrera S and 911 Carrera S
Cabriolet, Porsche Torque Vectoring
(PTV) increases dynamic performance.
Available as an option for the S models,
Porsche Dynamic Chassis Control (PDCC)
improves dynamic performance further
still. Dynamic engine mounts, available
as an option for all models, provide per ­
ceptibly more precise handling – and
not just when cornering.
The 911 has a light weight composite
construction in aluminium and steel.
Used extensively and in just the right
places, lightweight aluminium improves fuel economy and dynamic performance
and helps to achieve an excellent weight
to power ratio of 4.7 kg / kW (3.5 kg / hp)

for the 911 Carrera S, for example.
The future of the sports car begins now.

Meetings, conferences, business lunches.
How about some leisure in between?

The 911 Carrera.
In the 21st century, we find ourselves
caught bet ween all kinds of opposites on
a daily basis: bet ween the demands of
our work life and our private life, between
the real world and virtual realit y. How can
they all be reconciled? With a strong iden ­
tit y and a sports car that has incorporated
many contradictory notions since 1963.
Sportiness and everyday practicality
are a prime example. The 911 Carrera is
equipped as standard with direct fuel
injection (DFI) and VarioCam Plus for high
power, high torque, efficient combustion
and, as a result, comparatively low fuel
consumption. Tradition and innovation blend seamlessly
together in the rear
­mounted 3.4 ­litre
flat ­six engine thanks to its downsized
capacity. Despite the reduced displace ­
ment, the engine is capable of delivering
even more power to the road than its
3.6 ­litre predecessor.
The figures speak for themselves.
The maximum power of 257 kW (350 hp)
is available at 7,400 rpm and the maxi ­
mum torque of 390 Nm is generated
at 5,600 rpm. Yet, in conjunction with
Porsche Doppelkupplung (PDK), fuel
consumption and CO2 emissions have been
reduced by 16 % compared with the
previous model. Even more impres
sively,
the car accelerates from 0 to 62 mph
in 4.8 seconds and reaches a top speed
of 179 mph.
The 911 Carrera generates powerful
forces, which are transmit ted precisely
and directly to the wheels by the 7 ­speed
manual gearbox. As with the optional PDK,
gears 1 to 6 have a sports ratio, while
7th gear has a long ratio for reduced fuel
consumption. The SPORT but ton, which
is fit ted as standard, makes it possible to
select an even more responsive engine
and transmission setup.
In terms of form and function, the single
tailpipes are especially imposing and emit a sound which is t ypically Porsche. The
19
­inch Carrera wheels are fit ted as
standard and improve driving stability
and performance.
Sports car technology as standard, in
the form of black four ­piston monobloc
aluminium fixed calipers, Porsche Stability
Management (PSM) and Bi ­Xenon head ­
lights, shows that sportiness and safety
are not mutually exclusive.
Sport, moderation, everyday practicality
and st yle. Four key themes, one unifying
concept: the 911 Carrera.

| 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 Cabriolet
The future of the sports car
is wide open again.

The 911 Carrera Cabriolet.
Sometimes, the best option is to free
your mind, to look at things from a fresh
perspective and to explore your own
direction, not least when you’ve set
yourself ambitious goals for the future.
These goals can be achieved by opening
yourself up to new ideas.
This is the direction explored by the
911 Carrera Cabriolet. With forward ­
looking hood engineering, lightweight
materials and an integrated wind deflector,
it conceives a new kind of freedom and
broadens the appeal of the sports car.
Smooth and firm, light and robust, the
design of the hood is impressive in terms
of both appearance and construction.
It
is made from three ultra ­light weight
magnesium elements and is covered in

fabric. This saves weight and, not only
does it improve aesthetics, it also reduces
unwanted noise. What you can still hear,
however, is the unadulterated sound of
y o u r 9 11 .
The wind deflector is fit ted as standard
and offers practically draught ­free driving
and minimal wind noise. Operation could
not be easier. Integrated directly behind
the rear seats, it folds out electrically in
just t wo seconds and remains operable
up to a speed of 74 mph. The performance figures of the

911 Carrera Cabriolet reflect the ambi ­
tious goals achieved by our engineers.
The downsized and rear ­mounted 3.4 ­litre
flat ­six engine delivers 257 kW (350 hp)
at 7,400 rpm and enables a top speed of
177 mph. Compared with the previous
model, fuel consumption and CO
2 emis ­
sions have been reduced by 15 %.
In summary, this articulate concept forms
the basis for a self ­assured personalit y.
Typified by its courage to adapt and
change, it derives pleasure from exploring
new directions. After all, the future is
wide open.

| 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.

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
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 Carrera 911 – 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

downsizing the engine, it has been possible
to reduce the fuel consumption and CO
2
emissions by up to 15 % compared with
the previous model.

2 emissions, please refer to pages 139/141.

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

gear for fuel efficiency.
The 911 has many strengths. The new

dynamic performance and safet y, has
acquired even more. Why not take your
seat behind the wheel and make these
strengths your own?
