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 con
sumption and CO
2 emissions have been
reduced by 16 % compared with the pre
vious model. Even more impressively, 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, there
fore, 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
sport
ier aerodynamics and the ride height low
ered 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 con
junction with the optional PDK, increase
traction and driving stability. Porsche
Dynamic Chassis Control (PDCC), the ac
tive roll stabilisation system, is available
as an option and improves agilit y, com
fort and safet y. 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 short
er braking distance. Bi Xenon headlights
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 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.
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 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.

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.

Transmission
The long and winding road is where you’d like to be.
Sometimes, it pays to take the direct route.
Transmission.
The 7-speed manual gearbox.
Pure, direct, precise. Short shif t move
ments and an optimum transition from
one gear to the next. That ’s exactly what
you would expect of a Porsche manual
gearbox.
What you might not have expected is a
7 speed manual gearbox that combines
a high level of sport y performance with
an equally high level of efficiency and
offers extra comfort for longer journeys. It’s an exceptional innovation, and not
only in the sports car segment.
The design of this manual gearbox is
based in principle on that of Porsche
Doppelkupplung (PDK). Gears 1 to 6 have
a sports ratio and top speed is reached
in 6th gear. The additional 7th gear, how
ever, has a long ratio, which reduces
torque and helps to reduce fuel consump
tion. Lower engine revs at fast driving
speeds also ensure a high level of com
fort
on long stretches of road. In addition
, a gear indicator in the rev counter reminds
you which gear has been selected. The
upshift indicator in the instrument cluster
helps you actively conserve fuel.
Thanks to the elevated centre console,
the gear lever is within easy reach –
ideal for sport y gear changes.
Whether you select a sporty or comfortable
gear, the way you reach your destination
is in your own hands.
