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.

The vehicle architecture, with a wider
track at the front axle and the lower roof
line, gives the front of the 911 a dynamic
appearance that is sport y and elegant.
It has also helped us to achieve a low drag
coefficient of 0.29 for the 911 Carrera. Fit ted as standard, the Bi
­Xenon head ­
lights still have the familiar oval ­shaped
surrounds for classic appeal and reveal
their technically impressive inner work ­
ings. The Porsche Dynamic Light System
(PDLS) with dynamic cornering lights
and speed ­sensitive headlight control
logic is available as an option. The direction indicators, daytime running
lights and position lights are all LEDs and
are integrated into the separate front light
units. Their slimline design contrasts with

that of the rounded headlights. Together
with the two integral air intakes, they
make the front of the 911 unmistakable. At the rear, every thing is clean and
sharp: the styling, the appearance and
the effect. This is due not least to the
distinct lines and narrow LED taillights
which accentuate the horizontal contour
­
ing of the rear. The illuminated rear
light strip on the all ­wheel ­drive models
further enhances the effect. One unmistakable Porsche feature is

the stainless steel tailpipes. On the
911 Carrera S models, t win tailpipes
are fit ted on both sides. The wide rear
spoiler is extendable which reduces lift
in all driving situations and increases
driving stability. The 911 Carrera models and the

911 Carrera S models are equipped
as standard with 19 ­inch and 20 ­inch
wheels, respectively. Their large dimen ­
sions enhance the sport y presence of
the 911. The t yres have a large rolling
circumference for improved comfort
and performance. Even the logo on the rear has an impor
­
tant function to perform. It is, after all,
the hallmark of the Porsche identity.
In summary, form always follows function.
As a design principle, it couldn’t be more
simple, but it ’s what makes the 9 11 a 9 11.

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.

2 emissions, please refer to pages 143/145.

Engineered design.
The innovative bodyshell of the 911 fulfils
t wo structural design requirements: first,
excellent driving dynamics due to the
body’s extremely high rigidit y; second,
a vehicle weight saving of up to 65 kg
primarily as a result of the intelligent
lightweight construction. To meet the second requirement, we
employed state
­of­ the ­art techniques for
combining various materials in order
to utilise specific material properties
exactly where they are needed.
For the bodyshell, therefore, we used
very thin, but nevertheless extremely
rigid, sheets of steel. Aluminium and magnesium were used extensively in
areas such as the roof, underbody, front
end, doors, rear wings and engine com
­
partment and luggage compartment lids.
Magnesium, which is a particularly light ­
weight material, was also selected for
the cockpit and centre console support
beam and, in the Cabriolet models, the
hood shell elements. Such material effi ­ciency is key to reducing the overall
weight and, as a result, fuel consumption
of the vehicle.
For the driver, this intelligent blend

of materials reduces the weight of the
vehicle and offers a high level of comfort
thanks to excellent vibration ­damping
characteristics and particularly high com ­
posite rigidit y, an increase in dynamic
torsional stiffness of up to 25 % compared
with that of the previous model, and
even
sportier handling despite a further
improvement in the weight to power ratio.
The longer wheelbase improves comfort
as well as straight ­line accuracy and
driving stabilit y at high speeds and in
fast corners.

Front and rear axles.
The independent suspension at the front
features a light weight spring ­strut axle
with longitudinal and transverse links and
cross members that have been refined
for stiffness. Each front wheel is precisely
located, ensuring excellent directional stability, superior handling and reduced
pitching under braking, and the wide
track optimises turn
­in.
The rear axle is equipped with a
motorsport ­derived multi ­link suspension
and chassis subframe. Refined axle
kinematics for improved longitudinal
damping reduce acceleration squat and increase comfort. Light weight spring
struts further enhance agilit y.
The high proportion of aluminium used in
the construction of the axles reduces the
weight of the vehicle and of the unsprung masses, helping to improve fuel economy,
comfort and agility.

Hood.
Our engineers have completely redeveloped
the hood for the 911 Carrera Cabriolet
models. The result is a flexible roof
comprising a glass rear screen and three
individual and integral hood elements,
which are manufactured from magnesium
and covered in fabric. This makes the
hood highly robust and, yet, particularly
lightweight.
Another benefit is that the hood is
smooth and firm. The fabric remains taut
keeping the familiar 911 lines elegant. A trivialit y? Only if you choose to ignore
the impressively low drag coefficient

of just 0.30 for the 911 Carrera Cabriolet
models. A further feat of Porsche
engineering.
The rear screen is made from glass and
is electrically heated and scratch ­
resistant to provide excellent rearward
visibilit y. A rain channel on the hood
carries away water to avoid dripping
when the doors are opened.
Electrically powered, the hood is operat ­
ed using a but ton on the centre console
or via the key remote. It opens or closes in just 13 seconds and remains operable
up to a speed of 31 mph. The concertina
action ensures optimum protection for
the interior lining.
The interior hood lining is made from

a heat ­insulating and sound ­absorbing
material. Consistent interior temperatures
and an effective suppression of wind
noise are the perceptible results. Thank ­
fully, however, even the hood’s sound ­
proofing properties are no match for
the resonant Porsche sound.
Open, flexible, independent.
The optimum prerequisites for a long-term relationship.

Our identity is found under the bonnet,
in the design and behind the steering wheel.

Comfort.
Driving a 911 is first and foremost about
the feel of the road in the original,
unadulterated and direct sense. Is it
possible, then, to mention the 911 and
comfort in the same breath? To speak
of systems that make driving ‘more
agreeable’, or of materials that feel
‘pleasant ’ to the touch? Good question.
In reality, however, should anyone really
be forced to choose one over the other?
Let ’s introduce ourselves to the concept
of sport y comfort – dynamic performance
that maintains composure even when
pushed to the extreme.
Interior.
Engineering and st yle – and Porsche
identit y on the inside, as demonstrated
by the ascending centre console. In
t ypical Porsche fashion, the use of form
follows a basic principle: focus on the
driver. This is why the distance bet ween
the gear lever or selector and steering
wheel is extremely short and the operat ­
ing logic, such as that of the t wo ­zone
air conditioning system or the suspension
settings, is clear and uncomplicated.
You shouldn’t have to browse one sub­
menu after another. You should instead
be able to concentrate on what ’s
important: the road.
Our materials are high qualit y with a
sporty character. The steering wheel rim,
door pulls and armrests are in leather, for
instance. Alcantara has proven its worth
in motorsport and is used as standard
for the rooflining of the Coupé models.
In addition to the choice of Black,
Platinum Grey, Luxor Beige and Yachting
Blue for the interior, there is a wide
range of other personalisation options
available, including two ­tone colour
combinations or special colours and
materials such as carbon, aluminium
or high ­qualit y wood.

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.

Anti-theft protection.
All 911 Carrera models are equipped as
standard with an immobiliser with in
­key
transponder and an alarm system with
radar ­based interior surveillance. The
system secures the doors, luggage com ­
partment, passenger compartment and
ignition lock.
Preparation for Porsche Vehicle
Tracking System (PVTS).
Available as an option, this preparation
enables future installation of the Porsche
Vehicle Tracking System (PV TS) available
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,
the system automatically checks the
encrypted access code on the key. Once
the key is validated, the door or the luggage compartment lid unlocks. The
engine can then be started and switched
off using the electronic ignition switch.
To lock the vehicle, you simply press the
but ton on the outside of the door handle.
Porsche Entry & Drive then locks the
vehicle and activates the engine immobi
­
liser and steering column lock.
