2011 PORSCHE 911 CARRERA differential

Wheels.
On the new 911, the wheels have been
enlarged by one inch over the previous
model. Not only do the larger wheels
improve dynamic performance, they
also look more imposing.
The new 911 Carrera models are
equipped with 19-inch Carrera wheels as
standard. These are lightweight
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.
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.
The larger t yre size improves both ride
comfort and track performance. The

rolling resistance of the t yres
has been
reduced by up to 7 % to improve
fuel
economy, while t yre weight and dry brak -
ing distances have also been reduced. A selection of 20-inch wheels is available in
our range of options.
Tyre Pressure Monitoring (TPM).
Tyre Pressure Monitoring (TPM) is available
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 new 911 models

are equipped with enhanced Porsche
Stabilit y Management (PSM), which
maintains stability even at the limits of
dynamic driving performance. Sensors
continuously monitor the direction,
speed, yaw velocity 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 911 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.
Attack the corners.

Maintain good posture.

Porsche Torque Vectoring (PTV) and
Porsche Torque Vectoring Plus (PTV Plus).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 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.
