Chassis
Porsche Active Suspension
Management (PASM).
PASM is an electronic damping
control system. Available on
both Cayman models, it offers
continuous adjustment of
individual damping forces based
on current road conditions and
driving style. Agility and driving
pleasure are significantly
enhanced while retaining the
car’s natural ride quality. Equipped
with PASM, the car rides 10 mm
lower than with the standard
steel-sprung suspension.
The driver can choose one of
two setup modes, ‘Normal’ or
‘Sport’. While the first is a blend
of performance and comfort, the
‘Sport’ setup ratings are generally
much firmer, enabling greater
agility on the racetrack. In either
mode, the system responds to
changing loads by automatically
applying the optimum damping
rate on each individual wheel.
The rates are selected from a
range of map options which are
specially adapted to the unique
dynamics of the Cayman and
Cayman S.
The movement of the body is
continuously monitored under
acceleration, braking and cornering
manoeuvres, as well as on poor
road surfaces. Other sensors
provide additional information on
lateral acceleration, steering
angle, brake pressure and engine
torque. A dedicated control unitprovides real-time analysis and
damper adjustment as defined
for the respective setup mode
(‘Normal’ or ‘Sport’). The result:
greater stability and more
consistent occupant comfort.
If, when ‘Sport’ mode is selected,
the quality of road surface drops
below a certain threshold, the
system immediately switches
to
a softer rating and restores
the car’s traction and grip.
When the road surface improves,
PASM returns to the original,
harder ratings. The system
remains active in ‘Normal’ mode,
too, automatically switching to a
harder setup if the car is driven
more assertively. As the dampers
become stiffer, the car becomes
more stable and driver control is
improved.
