2014 PORSCHE 911 differential

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.

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.
