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.

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

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.
