Two different modes.
One driving feel: 911.
Porsche Active Suspension Management (PASM).
The electronic adjustme nt of
the suspension sy stem actively
and continuo usly regulates t he
damping fo rce for each wheel
according to the road conditions
and dr iving style. In addition,
the suspension is 0.39 of an inch
(10 mm) lower. PASM is fitted
as standard in the
S models
a nd is optional for
models
with the 3.6-liter engine.
At the push of a button, the driver
can select between two different
modes: “Normal,” which is a blend
of perfor mance and comfort,
and “Sport,” where the setup
is much firmer. The two setup
modes overlap slightly and so
the ba lance between comfortable
and uncompromisingly sporty
is struck more effectively than
with a conventional chassis.
Depen ding on the mode selected,
therefore, PASM is sportier
or more comfortable than the
standard chassis of models with
the 3 .6-liter engine. The PASM
control unit evaluates the driving
conditions and modifies the
damping fo rce on each
of the wheels in accordance
with the selected m ode.
Sensors monitor the movement
of the vehicle body, for example,
under heavy accelerat ion and
braking or on uneven roads. The
control unit tunes the dampers
to the optimal h ardness for the
selected mode to reduce roll
and pitch, and i ncrease contact
between eac h individual wheel
and the road.
In Sport mode, the suspension is
set t o a harder damper rating. On
uneven roads, PASM immediately
swit ches to a softer rating within
the Sport setup range, thereby
improving contact between
the wheels and the ro ad. When
the road surface improves,
PASM automatically rev erts to
the original, harder rating.
If Normal mode is selected and
the dri ver’s style becomes more
ass erti ve, PASM automatical ly
s witc hes to a harder rating
withi n the Normal set up range.
Damping becomes harder,
and dr iving stability and road
safety are in creased.
