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

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.

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.

Climate control.
The 911 models feature t wo
­zone auto ­
matic climate control as standard with
an enhanced ventilation effect and sepa ­
rate temperature controls for the driver
and front passenger. The available air
conditioning modes are gentle, normal
and strong.
An active carbon filter traps particles,
pollen and odours and an automatic
air ­recirculation function permanently
monitors air quality, reduces humidity

and switches from fresh to recirculated
air when required. A demister function keeps the windows
clear in cold weather. In warmer weather,
a solar sensor helps the climate control

to detect strong sunlight and automatically
compensate for the comfort of both the
driver and front passenger.
HomeLink® (programmable garage
door opener).
As an option, it is possible to have
a programmable garage door opener
integrated into the overhead console.
At the push of a but ton, it controls up
to three different garage doors, lighting
systems or alarm systems.
Many things have practical qualities.
Even more have a sporty function.
And some are just extremely convenient.

Additional comfort and convenience features.
Cruise control.
This automatic speed control function is
available as an option. For greater driver
comfort on long stretches of road, cruise
control operates in the 18–149 mph
speed range and is activated using a but ­
ton on the steering column control stalk.
Light design package.
The optional light design package is both
practical and aesthetically appealing.
It comprises dimmable LEDs in the over ­
head console and in the areas of the
door pulls, door storage compartments,
front foot wells and rear seats.
‘Welcome Home’ lighting.
For convenience, particularly at night,
the ‘Welcome Home’ lighting function
automatically switches on the LED day
­
time running lights for a defined period
whenever the vehicle is opened or
closed using the key remote.
A customisable delayed switch ­of f timer
keeps the daytime running lights, the

taillights and, where applicable, the
courtesy lights switched on until you
reach your front door.
Adaptive cruise control with Porsche
Active Safe (PAS).
Available as an option, this cruise control
function regulates your speed according
to the distance bet ween your vehicle and
the vehicle in front. A radar sensor moni ­
tors the road ahead up to a distance of
200 m. If you have set a cruising speed but have begun to gain on the vehicle in
front because it is driving more slowly,
this is detected by the radar sensor.
The system now reduces the speed

of your vehicle at a maximum rate of
3.5 m/sec
2 by restricting the throt tle
or by applying the brakes appropriate
to the prevailing situation until the dis ­
tance that you have preset is maintained. Your vehicle will now continue at a
reduced speed. If the other vehicle

decelerates further, adaptive cruise
control will continue to reduce your
cruising speed – even down to a halt. For additional safet y, if the system detects
that the distance from the vehicle in front
is decreasing, it will also prepare your
vehicle for braking by precharging the braking system so that the brake pads
are already in light contact with the
brake discs. However, drivers still have
to perform heavier braking themselves.
As soon as the road ahead clears again,
your vehicle will accelerate back up to
the cruising speed originally set.
If your vehicle approaches the vehicle

in front too quickly, Porsche Active Safe
(PAS) will issue audible and visual warn ­
ings. In addition, the system briefly jerks
the brakes and if necessary initiates
target braking, with any braking pressure
applied by the driver being increased
within certain system limits.
