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.

| 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.

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?

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.

The new 911 Carrera 4S Cabriolet.
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.

2 emissions, please refer to pages 139/141.

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.
