Are you a fan of sport y driving? In
your spare time, do you enjoy the
occasional outing on the racetrack?
Then you shouldn’t do without the
optional mechanically locking rear
differential available in conjunction
with 18-inch or 19-inch wheels.
It further enhances the traction of
the driven rear wheels on uneven
roads and when accelerating out of
tight bends, and the damping of
load-change reactions during
fast cornering is reduced. Road
holding at the limits of perform -
ance is even more impressive. The
car holds its course bet ter and so
PSM intervenes less often.
In other words, sheer driving

Porsche Active Suspension
Management (PASM).
The optional PASM is an electronic
damping control system.
PASM actively and continuously
regulates the damping force
for each wheel according to the
road conditions and driving
st yle. In addition, the suspension
is lowered by 10 mm.
The driver can select bet ween
t wo dif ferent modes: ‘Normal’
which is a blend of performance
and comfort, and ‘Sport ’
where the setup is much firmer.
Depending on the mode selected,
therefore, PASM is sportier
or more comfortable than the
standard chassis. The PASM
control unit evaluates the driving
conditions and modifies the
damping force on each of
the wheels in accordance with
the selected mode. Sensors monitor the movement

of the vehicle body, for example,
under heav y acceleration and
braking or on uneven roads. The
control unit tunes the dampers
to the optimum hardness for the
selected mode to reduce roll and
pitch still further and to increase
contact bet ween each individual
wheel and the road.
In ‘Sport ’ mode, the suspension
is set to a harder damper rating.
On uneven roads, PASM immedi -
ately switches to a softer rating
within the ‘Sport ’ setup range,
thereby improving contact
bet ween 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
within the ‘Normal’ setup range.
Damping becomes harder, and
driving stabilit y and road safet y
are increased.

it is automatically reactivated for

wheels (in ‘Sport ’ mode, both
of the front wheels) requires ABS
assistance. ABD remains perma -
nently active. Two additional
functions of PSM increase safet y
even further: precharging of the
brake system, and brake assist.
If you suddenly release the accel -
erator pedal, PSM automatically
readies the braking system. With
the braking system having been
precharged, the brake pads are
already in light contact with the
brake discs. Maximum braking
power is therefore achieved much rigidit y of the car. The forces

(PSM).
PSM, which comes as standard, is
an automatic control system that
stabilises the vehicle at the limits
of dynamic driving performance.
Sensors continuously monitor
driving direction, speed, yaw veloc-
it y and lateral acceleration. Using
this information, PSM computes the
actual direction of motion. If this
direction deviates from the desired
course, PSM initiates braking
interventions targeted at individual
wheels in order to stabilise the
vehicle.
sooner. When sudden braking is
detected, the brake assist function
applies maximum brake pressure
to all four wheels.

The system of longitudinal and
transverse members at the front
of the vehicle (1) distributes the
Under acceleration on wet or
low-grip road surfaces, PSM
improves traction using the ABD
(automatic brake differential)
and ASR (anti-slip regulation)
functions, giving an agile
response. When ‘Sport ’ mode is
selected on the optional Sport
Chrono Packages (p. 62), the PSM
intervention threshold is raised to
enable greater driver involvement
– particularly at speeds of up to
approximately 70 km/ h (45 mph).
The integrated ABS can further
reduce the braking distance.
For an even sportier drive, PSM
