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.

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?

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.

engine developing 257 kW (350 hp) at
7,400 rpm, which displays superlative per­
formance. The 0 to 62 mph sprint is
completed in 5.1 seconds, for example.
And it boasts a top speed of 175 mph.
Equally superlative are the fuel consump ­
tion and CO
2 emissions figures which
are up to 16 % lower than those of the
previous model.
When it comes to traction, however,
composure and reason prevail in the
form of the further enhanced Porsche
Traction Management (PTM) active all ­
wheel ­drive system. Working together
with Porsche Stability Management
It may come as a surprise to you, but

our engineers are very emotional people.
And clear thinkers. There is no conflict
bet ween these t wo traits. On the contrary,
they are ideal qualifications for those

tasked with the development of a cabrio ­
let that is more than just a fair ­weather
car: the new 911 Carrera 4 Cabriolet.
Entirely without contradiction, it com­
bines the thrills of open ­top driving with
outstanding road holding.
May we now appeal to your emotions?
Here goes. The new 9 11 Carrera 4

stabilit y and safet y. So you can give free
rein to your emotions. Even in the wet
and snow.
The new hood of the
9 11 Carrera 4
Cabriolet is able to adapt to the weather
and your mood in precisely 13 seconds.
That ’s all the time it needs to open or
close at road speeds of up to 31 mph.
Magnesium support elements make the
hood light weight, yet extremely rigid and
robust. An integral wind deflector is fit ted
as standard. Electrically powered, it
extends in just t wo seconds. There’s a feeling of pride that the fabric
hood creates the same elegant silhouet te
as that of the
9 11 Coupé models. The
powerful proportions – the body that is
44 mm wider at the rear, the wider rear
track and 295 mm wide rear t yres – are
characteristic of all ­wheel ­drive design.
All this combines to create that unique
Porsche cornering feel.
We think that it ’s bet ter to play out your
emotions than to conceal them. Because
only a weak character shows no feelings
at all. The new

Which vital ingredients do you need to
experience moments of true happiness?
It ’s our conviction, at least, that you need
impressive road holding. Plus safety,
reliabilit y and faith in technology that won’t
let you down when you need it most.
Because only when we have peace of

mind are we truly free.
All these ingredients have been brought
together in the 911 Carrera 4S Cabriolet.
The car, powered by a 3.8 ­litre direct fuel
injection (DFI) engine with a maximum out ­
put of 294 kW (400 hp) at 7,400 rpm,
sprints from 0 to 62 mph in 4.7 seconds
and boasts a top speed of 183 mph.

The strength of identity can be measured after all.
In moments of happiness.

The new 911 Carrera 4S Cabriolet.
Bringing additional peace of mind are the
fuel consumption and CO
2 emissions
figures of the new 911 Carrera 4S
Cabriolet, which are up to 14 % lower
than those of the previous model.
The car’s ‘happiness hub’, however, can
be found in the Porsche Traction
Ma na
gement (PTM) active all ­wheel ­drive
control system which has undergone fur ­
ther refinement. As a result, handling is
even more poised and balanced, particu ­
larly when the car is being driven at its
limits.
This makes controlling the car even
easier
and driving much more pleasura ­
ble.
The hood of the new 911 Carrera 4S
Cabriolet lets you open up to the open
road. The fabric hood featuring magne­
sium elements is light weight, yet robust
and extremely rigid. It opens in just
13 seconds at road speeds of up to
31 mph. When closed, it shows off an
aerodynamically optimised silhouette
that has a drag coefficient of just 0.31.
Which is also why you can hear hardly
any wind noise.
You can certainly hear the engine though.
The sound is – and remains – unmistakably
Porsche. Likewise the dimensions:
the car
is 44 mm wider at the rear, has a wide track and is equipped with wide rear
wheels on 20
­inch Carrera S t yres. All
evidence of that strong identit y.
It’s possible, of course, to describe mo ­
ments of happiness. But it ’s far bet ter to
experience them first hand. The new
911 Carrera 4S Cabriolet.

| 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.

“That can’t be done.”
If ever a sentence gave motivation to sports car designers, this is it.

Chassis and body.
A solid identit y tends to be described
with words like stability, directness or
substance. This might sound a lit tle
serious but, when it comes to the chassis
and body, we think that this is entirely
the right approach.
The best example is the engineered
design. Indeed, dynamic per formance
and ride comfort fundamentally depend
on factors such as vehicle weight, body
rigidity, wheelbase, axle construction
and steering. With the 911, we challenged
our engineers to push the boundaries
of what is possible. Chassis control systems make a key

contribution to the 911 driving experience
and thus to the 9 11 i d e n t i t y. T h e s e
include Porsche Stability Management
(PSM), Porsche Active Suspension

Management (PASM), which comes as
standard in the 911 Carrera S models,
Porsche Torque Vectoring Plus (PTV Plus).
Porsche Dynamic Chassis Control (PDCC)
is additionally available as an option for
the
9 11 Carrera S models.
Yet, there is still scope for improvement
as far as sport y performance is

concerned. The optional Sport Chrono Package triggers an adrenaline rush

at the push of a but ton. Dynamic engine
mounts, until now exclusively reserved

for 911 GT and Turbo models, may not be
capable of breaking the laws of physics
but they do succeed in exploiting them

to their own advantage – and yours.

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.
