It is possible to have a lot of power yet not
be able to use it. Only by using your power
intelligently will you truly progress – and
with consummate ease.
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.

Front and rear axles.
The independent suspension at the front
features a light weight spring-strut axle
with longitudinal and transverse links and
cross members that have been refined
for stiffness. Each front wheel is precisely
located, ensuring excellent directional stability, superior handling and reduced
pitching under braking, and the wide
track optimises turn-
in.
The rear axle is equipped with a
motorsport- derived multi -link suspension
and chassis subframe. Refined axle
kinematics for improved longitudinal
damping reduce acceleration squat and increase comfort. Light weight spring
struts further enhance agilit y.
The high proportion of aluminium used in
the construction of the axles reduces the
weight of the vehicle and of the unsprung masses, helping to improve fuel economy,
comfort and agility.

Engineered design.
The innovative bodyshell of the 911 fulfils
t wo structural design requirements: first,
excellent driving dynamics due to the
body’s extremely high rigidit y; second, a
low vehicle weight primarily as a result of
the intelligent lightweight construction.
To meet the second requirement, we
employed state -of -the- art techniques for
combining various materials in order
to utilise specific material properties
exactly where they are needed.

For the bodyshell, therefore, we used
very thin, but nevertheless extremely
rigid, sheets of steel. Aluminium and magnesium were used extensively in
areas such as the roof, underbody, front
end, doors, rear wings and engine com
-
partment and luggage compartment lids.
Magnesium, which is a particularly light -
weight material, was also selected for
the cockpit and centre console support
beam and, in the Cabriolet models,
the hood shell elements. Such material efficiency is key to
reducing the overall weight and, as a
result, fuel consumption of the vehicle.
For the driver, this intelligent blend of
materials reduces the weight of the
vehicle and offers a high level of comfort
thanks to excellent vibration-damping
characteristics and particularly high
composite rigidit y, a high degree of
dynamic torsional stiffness, and
especially sporty handling.
The long wheelbase improves comfort as
well as straight-line accuracy and driving
stabilit y at high speeds and in fast
corners.

SPORT button.
Fit ted as standard, the 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
automatically 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.
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.
Every day can be sports day.

Additional performance enhancement systems.Electromechanical 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 electromechanical power steering. Statis-

tics 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
bene ficial 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 agilit y, a high level of comfort
and precisely selected feedback from the
road. Our definition of efficient.
Power steering Plus.
Power steering Plus, the comfort-enhancing
power steering system, is available as an
option for the 911 Carrera models. At high
speeds, the steering is as firm as possible,
ensuring maximum precision whilst steer-
ing comfort remains as high. At low speeds,
the steering ratio of Power steering Plus
adjusts for much easier manoeuvring and
parking.

On activation of SPORT PLUS mode,
Porsche Active Suspension Management
(PASM) and, in the 911 Carrera S models,
optional Porsche Dynamic Chassis
Control (PDCC) switch to a harder
damping set ting and offer more direct
steering and, therefore, better
roadholding. In SPORT PLUS mode, the trigger
threshold for PSM is raised. Agilit y is
perceptibly enhanced when braking for
corners with PSM, allowing sportier
braking and exit acceleration. For even
greater 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 gearshift 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
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
recorded so far.
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 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.
The electronically controlled system
minimises the oscillations and vibrations
of the entire drivetrain, especially
the engine, and combines the benefits
of a hard or soft engine mounting
arrangement.
A hard engine mounting delivers optimum
dynamic performance because it offers
the highest degree of handling precision
possible. Soft engine mounts, on the
other hand, minimise oscillations and
vibrations. While comfort is improved on
uneven road surfaces, this comes at
the expense of dynamic performance. Our engineers have solved this problem
by enabling the engine mounts to adapt
their stiffness and damping properties to
changes in driving st yle and road surface
conditions. This has been achieved by
use of a fluid with magnetic properties in
interaction with an electrically generated
field. For the driver, the results are tangi-

ble. Handling is perceptibly more stable
under load change conditions and in
fast corners. Whenever a less assertive
driving st yle is adopted, the dynamic
engine mounts provide a higher level of
comfor t.

6869
Wheels.
The 911 Carrera models are equipped
with 19-inch Carrera wheels as standard.
These are light weight alloys featuring a
classic sport y design. Tyre sizes are
235/40 ZR 19 and 285/35 ZR 19 at the
front and rear, respectively. All-wheel-
drive models are fit ted with even wider
295/35 ZR 19 t yres at the rear.The S models are equipped with light-
alloy 20 -inch Carrera
S wheels as
standard. The visual effect is sport y and
dynamic. The t yres are slightly wider to
cope with the increased power output of
these models: 245/35 ZR 20 at the
front, 295/30 ZR 20 at the rear. All-
wheel-drive models have 305/30 ZR 20
t yres at the rear.
The large t yre size improves both ride
comfort and track performance. Rolling
resistance, dry braking distances and t yre
weight are all comparatively low, thereby
helping to reduce fuel consumption.
A selection of 20 -inch wheels is available
in our range of options.
Tyre Pressure Monitoring (TPM).
Integrated as standard, Tyre Pressure
Monitoring (TPM) sends warnings to the
on-board computer’s display screen in
the event of low t yre pressure or a
gradual or sudden loss of pressure. The
individual pressures in all four t yres can
be displayed in the instrument cluster.
Porsche Stability Management (PSM).
As standard, the 911 Carrera models are
equipped with enhanced Porsche Stability
Management (PSM), which maintains sta -
bilit y even at the limits of dynamic driving
performance. Sensors continuously moni -
tor the direction, speed, yaw velocit y and
lateral acceleration of the car. Using this
information, PSM is able to calculate the actual direction of travel at any given
moment. If the car begins to oversteer or
understeer, PSM applies selective braking
on individual wheels to restore stabilit y.
Under acceleration on wet or low-grip
road surfaces, PSM improves traction
using the automatic brake diffe
rential
(ABD) and anti -slip regulation (ASR).
When the SPORT PLUS mode of the
optional Sport Chrono Package is selected,
the PSM threshold is raised to allow a
sportier driving style.
For an even more dynamic experience,
you always have the option to deactivate
PSM. It is automatically reactivated,
for your safet y, only if you brake harder
and either of the front wheels (in SPORT
PLUS mode, both of the front wheels) requires ABS assistance. ABS and ABD,
however, remain active at all times.
PSM therefore offers a high level of

driving stability and safety combined
with extraordinary agilit y. It ’s an
apparent contradiction in terms, but an
intrinsic part of the Porsche identit y.

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.

Control, discipline, precision.

At Porsche, we take driving pleasure very seriously.

S a f e t y.
Brakes.
Another crucial piece of the Porsche
identit y is the brakes. We value them as
highly as we do our engines and chassis.
They set standards for deceleration and
stabilit y, and give the driver the reassur
-
ance needed to push the car to the limits
of its performance.
The 911 Carrera base models are fit ted
front and rear with anodised black four-
piston aluminium monobloc fixed
calipers. All brake discs have a diameter
of 330 mm. On the S models, we have fit ted larger
brakes and more brake pistons to cope
with the higher engine power of these
models. Consequently, they feature red
six-piston monobloc aluminium fixed
brake calipers at the front and four-piston
aluminium monobloc fixed calipers at
the rear. The brake disc diameter is
340 mm at the front and 330 mm at the
rear. The results are enhanced braking
performance and stability.
On all models, the brake calipers have
an enclosed monobloc construction.
This makes them tougher but lighter
and enables a more rapid response and release of the brake even under extreme
loads. The pedal travel is short and

the biting point precise. The brake discs
are cross-drilled for better performance
in the wet.
Other benefits of the standard braking
system include the anti-lock braking
system (ABS), designed to keep
deceleration constant. Pedal effort is
reduced and braking response improved
by an 8-/9-inch tandem vacuum brake
booster. In the S models, brake disc
cooling is further enhanced by the
inclusion of air spoilers.

Electric parking brake.
The electric parking brake, which you
can activate and deactivate manually,
releases automatically as you pull away.

With the hill-
hold function, you can
pull away without ever rolling back.
The system automatically detects when
the vehicle has come to a halt on an
uphill gradient requiring intervention.
PSM then maintains the brake pressure
at all four wheels to prevent the vehicle
from moving in the opposite direction.
Airbags.
The 911 Carrera models offer advanced
airbag technology in the form of full-size
driver and front passenger airbags, which
are inflated in t wo stages depending
on the severit y and t ype of accident (e.g.
frontal or offset frontal). In less serious
accidents, the airbags are only partially
inflated, thereby minimising discomfort
to the occupants. In addition to the central airbag control
unit on the transmission tunnel, a pair of
impact sensors are located near the
headlights. This allows a crash to be
detected and evaluated not just sooner,
but with even greater accuracy.
Porsche Side Impact Protection
System (POSIP).
Coupé or Cabriolet, the 911 models

are equipped as standard with the
Porsche Side Impact Protection System
(POSIP). It comprises side impact
protection elements in the doors and t wo airbags on each side. An integral
thorax airbag is located in each seat side
bolster, while the door panels each
contain an upwards-inflating head airbag.
Each thorax airbag has a volume of
10 litres and each head airbag 15 litres,
ensuring excellent protection in the event
of a side impact.
Cabriolet roll-over protection concept.
Despite their low weight, the 911 Carrera

Cabriolet models have exemplary
torsional rigidit y and flexural strength.
Body flexing is minimal even on irregular
road surfaces.
Increased protection is provided by
an automatically deploying roll-over
protection system if the car were to
overturn. Two spring-loaded roll-over
bars are neatly incorporated behind
the rear seats. The roll- over sensor
continuously monitors the car’s pitch
and roll, contact with the road, as
well as lateral and longitudinal forces.
If the car were to overturn, the roll- over
bars would be deployed instantly.

Lights.
Composure | Safet y
The 911 Carrera models are equipped as
standard with Bi-Xenon headlights
including a headlight cleaning system
and dynamic range control. The LED
front light units incorporate indicators,
day time running lights and position
lights. Automatic headlight activation is
also included as standard.
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, the rear fog
light and – on all-wheel- drive models –
the rear light strip. LEDs provide bet ter
illumination and respond more quickly
to driver input.
In the event of sudden braking, the adap -
tive LED brake lights begin to pulsate.
If the vehicle is braked to a halt, the
hazard warning lights will switch on
automatically. The lighting system
fea tures an automatic switch-
off and

the ‘Welcome Home’ function.
Porsche Dynamic Light System (PDLS).
The Porsche Dynamic Light System
(PDLS) is available as an option. 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. Speed -sensitive head-
light range control is also part of the
PDLS as is the adverse weather function.
LED main headlights with Porsche
Dynamic Light System Plus (PDLS +
).

Superior safet y meets sport y design in
the form of the LED main headlights with
PDLS+ which are available as optional
equipment. Integrated into each headlight
housing are four LED spots for the
day time running lights, and one LED light
ring. In addition to being efficient and
long-lasting, LED technology also creates
a light very similar to daylight and thus
helps to reduce driver fatigue. One special feature of PDLS+ is the
dynamic main beam function. A camera
detects the lights of vehicles ahead
as well as those of oncoming traffic.
Based on the data from the camera, the
dynam
ic main beam function then adapts
the headlight range accordingly. This continu
ous, stepless control means that
you are able to see the course of the
road, pedestrians and potential hazards
earlier without hindering other road
users.
