| 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.
For fuel consumption and CO
2 emissions, please refer to pages 139/141.
Strength | The new 911 Carrera 4
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 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.

engine developing 257 kW (350 hp) at
7,400 rpm, which displays superlative
performance.
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
wheel­drive system. Working together
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 fair­weather
car: the new 911 Carrera 4 Cabriolet.
Entirely without contradiction, it com­
bines the thrills of open­top driving with
outstanding road holding.

with Porsche Stabilit y Management (PSM),
PTM ensures excellent levels of stability
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 all­wheel­drive 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
output 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.
Strength | The new 911 Carrera 4S Cabriolet
The strength of identity can be measured after all.
In moments of happiness.

Bringing additional peace of mind are the
fuel consumption and CO
2 emissions fig ­
ures 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
Management (PTM) active all ­wheel ­drive
control system which has undergone
further refinement. As a result, handling
is even more poised and balanced,
particularly when the car is being driven
at its limits.
This makes controlling the
car even easier
and driving much more
pleasurable.
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 – unmistaka ­
bly 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
moments of happiness. But it ’s far bet ter
to experience them first hand. The new
911 Carrera 4S Cabriolet.

Engines
To give more and take less.
That’s Porsche engineering.

Engines.
You could ask whether the sports car is
still relevant. It would be a good question,
but you might as well ask the same of
dreams.
The answer to both questions lies in the
future or, to be more precise, in the future
of the sports car. In the 911, the future
is already here. The highly efficient, state ­
of­the ­art engines make a considerable
contribution to the comparatively low fuel
consumption, but their sound is still
unmistakably Porsche. The 911 engines are also unmistakably
sport y thanks to the SPORT but ton fit ted
as standard. At the push of a but ton, the
engine becomes tuned for a sharper
response and engine dynamics that are
even more direct.
The 3.4
­litre engine of the 911 Carrera
models demonstrates, therefore, that
performance and efficiency need not be
mutually exclusive. Rather, the downsized
engine capacity and increased maximum
torque are the intelli
gent basis by which
power output can be increased in an
environmentally acceptable and sustain­
able way. Fuel consumption and CO
2
emissions have been reduced by up to
16 % compared with the previous model. In their search for improved efficiency,
our engineers analysed an extensive series
of engine components. Answers were
found, including rapid heating of the
engine and gearbox to normal operating
temperature after an engine start by the
thermal management system, improved
air induction and extremely effective
direct fuel injection (DFI).
The same principle applies to the 3.8 ­litre
engine in the 911 Carrera S models.
There has been no change in displace ­
ment since the previous model, but
power output has been increased while
fuel consumption has been reduced by
up to 15 %. Weight is critical to efficiency. This is

why the engines have a light­alloy
construction, making them lightweight
and yet structurally rigid. The result
is comparatively low fuel consumption
and a long service life.
The engine is the intelligent core of our
identit y. What else could the ‘Dr. Ing.’ in
our company name possibly stand for?

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.
