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 produces 257 kW
(350 hp); in the 911 Carrera S, the 3.8-
litre engine develops 294 kW (400 hp).
Both models are equipped with direct
fuel injection (DFI) and VarioCam Plus
for increased power and reduced fuel
consumption. This power is transmit ted
to the wheels by the new and efficient
7-speed manual gearbox or, optionally,
by Porsche Doppelkupplung (PDK), which offers gear changes with no interruption
in the flow of power.
Both engines deliver improved sport y
performance compared with the engine
in the previous model and yet fuel

consumption has been reduced by up
to 16 %. How was this achieved? One
explanation is the reduced capacit y of
3.4 litres in the 911 Carrera. Another is
the total redevelopment of the engine
peripherals with groundbreaking efficiency-
improving technologies.
As standard, these include the auto
start/stop function, electrical system
recuperation and intelligent thermal management as well as the new, energy-
saving electromechanical steering system
and, in the case of PDK, the introduction
of the coasting function (for more infor
-
mation, please refer to page 39 onwards).
The chassis is also packed with forward-
looking technology. Fit ted as standard
in the 911 Carrera S, Porsche Torque
Vectoring (PT V) increases dynamic perfor -
mance. Available as an option for the
S model, Porsche Dynamic Chassis Control
(PDCC) improves dynamic performance
further still. Dynamic engine mounts,
included as part of the optional Sport
Chrono Package, are now available for
the 911 Carrera models for the first time. These provide perceptibly more stable
handling under load change conditions
and in fast corners.
The new 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 a low weight to power
ratio of 4.7 kg / kW (3.5 kg / hp) for the
9 11 C a r r e r a S .
The future of the sportscar begins now.

911 Carrera: 390 Nm at 5,600 rpm, 257 kW (350 hp) at 7,400 rpm
The new 3.4-litre engine.
The 911 Carrera is equipped with a

3.4-litre boxer engine with direct fuel
injection (DFI) and VarioCam Plus. It
develops 257 kW (350 hp) at 7,400 rpm
and the maximum torque is 390 Nm at
5,600 rpm.
For the 911 Carrera with 7-speed
manual gearbox, this means acceleration
from 0 to 100 km/ h (0 to 62 mph)
in 4.8 seconds and a top speed of
289 km/ h (179 mph). With the optional
Porsche Doppelkupplung (PDK), it
means 0 to 100 km/ h (0 to 62 mph)
in just 4.6 seconds and a top speed
of 287 km/ h (178 mph).
The new 3.8-litre engine.
The 911 Carrera S is powered by a
3.8-litre boxer engine with direct fuel
injection (DFI) and VarioCam Plus. It
produces 294 kW (400 hp) at 7,400 rpm
and the maximum torque of 440 Nm
is achieved at 5,600 rpm.
As a result, the new 911 Carrera S with
7-speed manual gearbox completes the
sprint from 0 to 100 km/ h (0 to 62 mph)
in 4.5 seconds and reaches a top speed
of 304 km/ h (188 mph). With the optional
Porsche Doppelkupplung (PDK), the
figures are 0 to 100 km/ h (0 to 62 mph)
in 4.3 seconds and a top speed of
302 km/ h (187 mph).

“That can’t be done.”
If ever a sentence gave motivation to sportscar 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 new 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 (standard in the 911 Carrera S):
Porsche Stability Management (PSM),
Porsche Active Suspension Management
(PASM) and Porsche Torque Vectoring
(PTV) or, in conjunction with PDK,
Porsche Torque Vectoring Plus (PTV Plus).
Porsche Dynamic Chassis Control (PDCC)
is additionally available as an option for
the 911 Carrera S. 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.

It ’s easy, and even makes sense, to carry
on in your usual way, but what happens
if a sudden change of direction leaves
you thrown off course? Then, it all comes
down to personal strength.
A Porsche has a clear sense of purpose
and is the embodiment of strength.
It demonstrates this with sport y and pre -
cise handling and excellent road holding. With the optional Porsche Dynamic

Chassis Control (PDCC) for the S model
of the new 911, these characteristics can
be further accentuated: the 911 Carrera S
holds the road even bet ter and delivers
even sportier performance. PDCC is an active anti-roll system that
anticipates and reduces lateral body
movement during cornering manoeuvres.
In addition, it minimises the lateral insta
-
bilit y of the vehicle on uneven ground.
This effect is achieved with the aid of
hydraulic stabilising actuators in the form
of cylinders designed to optimise camber.
Lateral roll is counteracted by forces
generated at each individual wheel, based
on steering angle and lateral acceleration.
Rapid cornering in the 911 Carrera without PDCC (illustrative example) Rapid cornering in the 911 Carrera S with PDCC (illustrative example)
You appreciate directness.
But love a few twists and turns.

Porsche Dynamic Chassis Control (PDCC).The results are improved dynamic
performance and increased ride comfort
at all speeds, as well as optimised turn-in
and stable load transfer characteristics.
In simple terms, the vehicle holds the
road bet ter and you can steer through
corners faster and in a more relaxed
m a n n e r.
PDCC sets new standards for handling
performance, ride comfort and driving
pleasure. In the new 911, your ‘usual’
way suddenly becomes the Porsche way.

Power steering.
Another possible definition of efficiency
is a system that works only when it is
needed, and then does so in a particularly
effective way.
This was the guiding principle for our
engineers in the development of the new electromechanical power steering.
Statistics show that a car drives in a
straight line 90
% of the time. Unlike
conventional hydraulic pumps, the electric
motor uses energy only when the steering
wheel is actually turned. The absence
of hydraulic fluid also makes the system
more beneficial to the environment.
As far as the other 10 % is concerned, we’re
optimally prepared as the steering system
is t ypically Porsche. It features a variable
steering ratio and responds sensitively
and directly at the same time as providing
customary agility, a high level of comfort
and precisely selected feedback from the
road. Our definition of efficient.Power steering Plus.
Power steering Plus, the speed -sensitive
power-steering system, is available
as an option for the 911 Carrera models.
At high speeds, the steering is as firm
as you would expect and responds with
extreme precision while steering comfort
remains as high. At low speeds, the
steering ratio of Power steering Plus
adjusts for much easier manoeuvring
and parking.
SPORT button.
Fit ted as standard, the new SPORT
but ton enables you to select a suspension
setup where the emphasis is on either
comfort or sport y performance. At the
push of a button, the electronic engine
management system switches the engine
mapping to offer an even sharper
response and engine dynamics that are
more direct.
In vehicles with Porsche Doppelkupplung
(PDK), upshifts take place at higher
engine speeds and downshifts happen sooner. In addition, coasting mode and
the auto start/stop function are automati
-
cally deactivated. If fitted, the optional
sports exhaust system is also activated
automatically.
Sport Chrono Package.
The Sport Chrono Package including
dynamic engine mounts is available
as an option. This integrated system
provides simultaneous enhancement for
the chassis, engine and transmission.
Every day can be sports day.

Additional performance enhancement systems.

Included in the package are a performance
display, a digital and an analogue stop -
watch and the SPORT PLUS but ton. An
additional display in the steering wheel
and instrument cluster indicates whether
the SPORT but tons and Launch Control
have been activated.
On activation of SPORT PLUS mode,
Porsche Active Suspension Management
(PASM) and, in the S model, optional
Porsche Dynamic Chassis Control (PDCC)
switch to a harder damping set ting
and offer more direct steering and,
therefore, better road holding.
In SPORT PLUS mode, the trigger thresh -
old for PSM is raised. Agilit y is perceptibly
enhanced when braking for corners with
PSM, allowing sportier braking and exit
acceleration. For maximum dexterit y,
PSM can be set to standby while the car
is still in SPORT PLUS mode. For safet y,
it is set to intervene automatically only
when ABS assistance is required on both
the front wheels.
In combination with PDK, the Sport
Chrono Package has t wo additional functions for a sport y drive that borders
on a motorsport experience. The first

is ‘Launch Control’, which can be used
on the track to achieve the best possible
standing start – a racing start.
The second function is the ‘motorsport-
derived gearshif t strategy’. Using this,
Porsche Doppelkupplung (PDK) is geared
up for extremely short shift times and optimum shift points for the maximum
acceleration available. This combination
of uncompromising and involving perfor
-
mance is ideal for the racetrack.
A key component of the Sport Chrono
Package is the stopwatch mounted on
the dashboard. In conjunction with the
optional PCM, a special performance
display enables you to view store and evaluate lap times or other driving
times. It shows the total driving time,
lap distance, lap number and lap times
re c o rde d s o f a r.
A feature of the Sport Chrono Package
borrowed from motorsport is the dynamic
engine mounts. These exploit the laws

of physics for your own driving pleasure.
Dynamic engine mounts.
You don’t have to take the new 911 onto
the racetrack. But you can, more so
than ever, because dynamic engine
mounts are now included as part of the
Sport Chrono Package. Based on the
engine mounts of the 911 GT3 and
911 Turbo models, it is the first time that they have been available for the

911 Carrera. Even if track racing is
not for you, dynamic engine mounts
make a decisive contribution to dynamic
performance on the road, too.
The electronically controlled system mini -
mises the oscillations and vibrations of the
entire drive train, especially the engine.
The engine is bolted to the body by t wo
mounts. Like any mass, it obeys the law
of inertia. This means that it will continue
moving in a uniformly straight line unless
some force causes it to change direction.
Put more simply: when you are driving
into a bend, the vehicle will follow your
steering but, at first, the mass of the
engine will not. This means that the rear
of the vehicle will ultimately be pushed
out wards as a result of the engine’s
force of inertia.
Dynamic engine mounts minimise
this effect. Steering angle and both
longitudinal and lateral acceleration
are constantly recorded by sensors. The stiffness and damping performance
of the engine mounts adapt to changes
in driving st yle and road surface condi
-
tions, which is achieved by use of a fluid
magnetised in an electrically generated
field. This results in greater traction
and perceptibly more stable handling
under load change conditions and in
fast corners.

PTV in conjunction with the manual gear -
box, or PT V Plus with Porsche Doppel-
kupplung (PDK), are available as options
for the 911 Carrera and standard in the
911 Carrera S. Both systems actively
enhance vehicle dynamics and stabilit y.
Operating in conjunction with a mechanical
(PT V) or electronic (PT V Plus) rear
differential lock, they work by 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.
Attack the corners.

Maintain good posture.

Porsche Torque Vectoring (PTV) and
Porsche Torque Vectoring Plus (PTV Plus).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 stability. With PTV, the differential
lock is regulated mechanically; with 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.

The 911 Carrera and 911 Carrera S are
both equipped as standard with Bi-Xenon
headlights including a headlight cleaning
system and dynamic range control.

With dipped or main beam, the road
ahead is illuminated more uniformly.
The rest yled LED front light units
incorporate direction indicators, daytime -
running lights and position lights.
Both 911 models come with automatic
headlight activation. The moment it gets
dark, the daytime running lights switch
off and the dipped beam headlights
switch on automatically. Cut ting edge LED technology is also used
for the taillights, the high-level third brake
light, the licence plate illumination, the
rear direction indicators and the rear fog
light. LEDs provide bet ter illumination and
respond more quickly to driver input.
In the event of sudden braking, the adaptive
LED brake lights begin to pulsate. If the
vehicle is braked to a halt, the hazard
warning lights will switch on automatically,
alerting following traf fic more quickly to

a critical situation.
The lighting system features an automatic
switch-off and the ‘Welcome Home’
function. It ’s good to know what ’s around
the next corner or on the way to your
front door.
Porsche Dynamic Light System (PDLS).
The Porsche Dynamic Light System
(PDLS) is available as an option for both
models.
Its dynamic cornering light function
swivels the headlights towards the inside
of a bend, based on steering angle and road speed, in order to illuminate more
of the road at tight bends and turns.

Put simply, the road ahead is illuminated
the moment you enter a bend.

the vehicle. PDLS takes care of this
automatically in t wo stages. Stage 1 is
the basic position for driving in cit y traffic,
for example. Stage 2 is designed for
driving at faster speeds, such as on the
motorway. Above 130 km/ h (80 mph),
the range is adapted again.
Another feature of PDLS is the adverse
weather function, activated whenever the
rear fog light is switched on. It reduces
the effect of reflection phenomena in
poor visibilit y conditions to avoid the risk
of the driver being dazzled.

Our identity is found under the bonnet,
in the design and behind the steering wheel.

Comfort.
Driving a 911 is first and foremost about
the feel of the road in the original, unadul -
terated and direct sense. Is it possible,
then, to mention the 911 and comfort in
the same breath? To speak of systems
that make driving ‘more agreeable’, or of
materials that feel ‘pleasant ’ to the touch?
Good question.
In reality, however, should anyone really
be forced to choose one over the other?
Let ’s introduce ourselves to the concept
of sport y comfort – dynamic performance
that maintains composure even when
pushed to the extreme.
Interior.
Engineering and st yle – and Porsche
identit y on the inside, as demonstrated by
the new elevated centre console. In t ypical
Porsche fashion, the use of form follows
a basic principle: focus on the driver. This
is why the distance bet ween the gear lever
or selector and steering wheel is extremely
short and the operating logic, such as that
of the two-zone air conditioning system
or the suspension set tings, is clear and
uncomplicated. You shouldn’t have to
browse one submenu after another. You
should instead be able to concentrate
on what ’s important: the road.
All our materials are high qualit y. Sport y
and elegant leather is used, for example,
on the steering wheel rim, on the door
handles and armrests and on the partial
leather seats, which are fit ted as standard.
Alcantara has proven its worth in motor -
sport and is used as standard for the
rooflining.
In addition to the choice of Black, Plati -
num Grey, Luxor Beige and Yachting Blue
for the interior, there is a wide range of
other personalisation options available,
including two-tone colour combinations
or special colours and materials such as
carbon, aluminium or high-quality wood.
