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. Sensors record the body movements

that accompany powerful acceleration,
braking or uneven road surfaces. In the
911, the number of sensors has been
increased for improved data acquisition
and even more ef ficient control interven­
tions. 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 between
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 stability
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 (PTV) 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.

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 precise
handling and excellent road holding.
With the optional Porsche Dynamic
Chassis Control (PDCC) for the S models
of the 911 Carrera, these characteristics
can be further accentuated: the vehicle
holds the road even bet ter and delivers
even sportier performance. PDCC is an active anti
­roll system that
suppresses lateral body movement during
cornering manoeuvres. In addition, it
minimises the lateral instability 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.

You appreciate directness.
But love a few twists and turns.

Porsche Dynamic Chassis Control (PDCC).The results are improved dynamic perfor ­
mance and increased ride comfort at all
speeds, as well as optimised turn ­in and
stable load transfer characteristics.
In simple terms, the t yres and vehicle
hold the road bet ter and you can steer
through corners faster and in a more
re l a x e d m a n n e r.
PDCC sets standards for handling perfor ­
mance, ride comfort and driving
pleas­
ure. In the 911, your ‘usual’ way suddenly
becomes the Porsche way.

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 agility, 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.
SPORT button.
Fit ted as standard, the SPORT button
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.
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.

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 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
standard 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 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 mini­
mises 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
comfort.

Wheels.
The 911 Carrera models are equipped
with 19­inch 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 20­inch 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).
Tyre Pressure Monitoring (TPM) is avail­
able on request. This safet y system 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 differential
(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 st yle.
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 gear­
box, or PT V Plus with Porsche Doppel ­
kupplung (PDK), are available as options
for the 911 Carrera models and standard
in the 9 11 Carrera 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
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 stability. With PTV, the differential
lock is regulated mechanically; with

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.

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 ele ­
ments 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 pro ­
tection 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 the most poorly sur ­
faced roads.
Increased protection is provided by an
automatically deploying roll ­over protec ­
tion system if the car were to overturn.
t wo spring­loaded 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.

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 direction indi ­
cators, day time running lights and posi ­
tion 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 adaptive 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 features an automa­
tic
switch ­off and the ‘Welcome Home’
function.
Porsche Dynamic Light System (PDLS).
The Porsche Dynamic Light System
(PDLS) is available as an option. Its dy ­
namic 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.

which are available as optional
equipment. Integrated into each head ­
light 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.

Lights.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 dy ­
namic main beam function then adapts
the headlight range accordingly. This
continuous, stepless control means that
you are able to see the course of the road, pedestrians and potential hazards
earlier without hindering other road
users.
