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 k W
(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 high power and
comparatively 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, Porsche Traction Management
(PTM) distributes the power to the
wheels according to weather and road
conditions. Handling remains 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
(PT V) – or Porsche Torque Vectoring Plus
(PTV Plus) in conjunction with PDK –
increases dynamic perfor mance. 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 tangible,
more precise handling – not only in the
bends.
The 911 has a lightweight 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 4.8 kg / kW (3.5 kg / hp)
for the 911 Carrera S, for example.
The future of the sports car starts 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 new 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 3.4-litre, six-cylinder
horizontally opposed engine. The figures
speak for themselves. The maximum
power of 257 kW (350 hp) is available at
7,400 rpm and the maximum torque of
390 Nm is generated at 5,600 rpm. Even
more impressively, the car accelerates
from 0 to 100 km/ h in 4.8 seconds and
reaches a top speed of 289 km/ h.
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 that is t ypically Porsche.
The 19-inch Carrera wheels are fit ted as
standard and offer excellent driving
stability and performance.
Sports car technology as standard, in
the form of black four-piston aluminium
monobloc fixed calipers, Porsche
Stabilit y Management (PSM) and Bi-Xenon
headlights, shows that sportiness and
safet y 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 911 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 maxi-
mum torque of 440 Nm is achieved
at 5,600 rpm. In conjunction with
the manual gearbox, the sprint from
0 to 100 km/ h is completed in a
mere 4.5 seconds. Top speed isn’t
reached until 304 km/ h.
On figures alone, the new 911 Carrera S
excels, particularly in terms of efficiency,
fuel consumption and CO
2 emissions.
This is made possible by the auto start /
stop function, which is available as
standard, and the coasting function

in conjunction with optional Porsche
Doppelkupplung (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
improved braking performance and a
shorter braking distance. Bi-Xenon
headlights are standard, while the
Porsche Dynamic Light System (PDLS)
and LED main headlights including
Porsche Dynamic Light System Plus
(PDLS
+
) are available as options.
There is no doubt. The 911 Carrera S
knows its roots, and embraces them
with efficiency, power and sport y
performance.

“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 performance
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 911 identit y. These
include Porsche Stability Management
(PSM), Porsche Active Suspension
Management (PASM), which comes as
standard in the 911 Carrera S models,
Porsche Torque Vectoring (PT V) and
Porsche Torque Vectoring Plus (PT V Plus)

in conjunction with PDK. Porsche Dynamic
Chassis Control (PDCC) is additionally
available as an option for the 911 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 recently 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.

PASM, the electronic damping control
system, is standard in the 911 Carrera S
models and available as an option for
the 911 Carrera models. It actively and
continuously regulates damping forces
according to driving st yle and road
conditions. In addition, the suspension
is lowered by 10 mm.
PASM has t wo modes, which can be
selected using a separate but ton on
the centre console: ‘Normal’, which is a
blend of performance and comfort, and
‘Sport ’ where the setup is much firmer. To ensure efficient control interventions,
a multitude of sensors in the 911 record
the body movements that accompany
powerful acceleration, braking or uneven
road surfaces. The PASM control unit
evaluates the driving conditions and
modifies the damping force on each of
the wheels in accordance with the
selected mode.
In ‘Sport ’ mode, the suspension is set to
a harder damper rating. On uneven roads,
PASM immediately switches to a softer
rating, thereby improving contact bet ween the wheels and the road.

When the road surface improves, PASM
automatically reverts to the original,
harder rating. If ‘Normal’ mode is selected
and the driver’s st yle becomes more
assertive, PASM automatically switches
to a harder rating. Damping firms up,
and driving stabilit y and road safet y are
increased.
The results are tangible: increased
driving stability, improved comfort and
enhanced performance.
No need to let the laws of physics
spoil your fun.

Porsche Active Suspension Management (PASM).PASM sports suspension.
The PASM sports suspension is available
as an option for the 911 Carrera Coupé
models in conjunction with 20-inch
wheels and Porsche Torque Vectoring
(PT V) or Porsche Torque Vectoring Plus
(PTV Plus). The ride height is 20 mm lower than

with the standard suspension or 10 mm
compared with the PASM suspension.
The springs are harder and shorter, and
the anti-roll bars on the front and rear
axles are stiffer. The front spoiler lip has
a more sport y geometry, the rear spoiler
extends even further. These not only further reduce lift at the front axle, but
also provide downforce at the rear axle
for improved aerodynamics and even

better performance.

PTV in conjunction with the manual
gearbox, or PT V Plus with Porsche
Doppelkupplung (PDK), are available as
options for the 911 Carrera models and
standard in the S models. Both systems
actively enhance vehicle dynamics and
stability. Operating in conjunction with a
mechanical (PT V) or electronic (PT V Plus)
rear differential lock, they work by
intelligently braking the rear wheels as
the situation demands.
As a function of steering angle and steering
speed, accelerator pedal position, yaw

rate and vehicle speed, PT V and PT V Plus

are able to improve steering response
and steering precision by specific braking
of the right or left rear wheel.
To be more precise, this means that when
the car is driven assertively into a corner,
moderate brake pressure is applied to the
inside rear wheel. Consequently, a greater
amount of drive force is distributed to the
outside rear wheel, inducing an additional
rotational pulse (yaw movement) around
the vehicle’s vertical axis. This results in
a direct and sport y steering action as the
car enters the corner.
At low and medium vehicle speeds, PT V
and PT V Plus significantly increase agilit y
and steering precision. At high speeds
and when accelerating out of corners,
the rear differential lock ensures greater
driving stabilit y. With PT V, the differential
lock is regulated mechanically; with
Attack the corners.
Maintain good posture.

Porsche Torque Vectoring (PTV) and
Porsche Torque Vectoring Plus (PTV Plus).

PT V Plus, it is regulated electronically and
the torque distribution is infinitely varia ble.
Whichever system is fit ted, it interacts

with Porsche Stabilit y Management (PSM)
to improve driving stabilit y on a range
of surface conditions, including the wet
and snow.
For the driver, this means remarkable
stability, easier handling and outstanding
traction as well as greater agilit y at every
speed with precise steering and stable
load transfer characteristics. What else?
Unrivalled driving pleasure at every t wist
and turn.
