compression ratio PORSCHE 911 2009 5.G Information Manual

The independent front suspension
combines McPherson-type struts
with longitudinal and transverse
links. Each front wheel is pre-
cisely located, ensuring excellent
handling and directional stabilit y. Proven in motorsport, the rear
axle assembly features multi-link
LSA (Light weight, Stable, Agile)
subframe-based suspension. Its
light weight construction of fers
excellent dynamic properties. The
axle kinematics improves stabilit y
under acceleration by reducing excessive compression. The light
-
weight strut has an aluminium
damper instead of conventional
steel to help improve handling
and agility.
The resulting suspension enables
smooth high -speed manoeuvres
in all road and track scenarios.
Pitch and roll are reduced to a
minimum, as are t yre noise and
vibration. The car offers excep -
tionally high levels of stabilit y.

Porsche Active Suspension
Management (PASM).
Included as standard equipment,
Porsche Active Suspension
Management (PASM) is an elec -
tronic active damping system.
It of fers continuous adjustment of
the damping force on each wheel,
based on current road conditions
and driving st yle.
At the press of a but ton, the
driver can choose bet ween t wo modes. While ‘Normal’ mode

provides a blend of performance
and comfort, the ‘Sport ’ setup
mode has a much firmer range of
set tings. The system responds
to changing road conditions and/
or driving st yle by continuously
varying the individual damping
forces within the parameters
defined for the selected setup
mode (‘Normal’ or ‘Sport ’).

Pitch and roll are reduced, whilst
contact of each wheel with the
road is optimised.
What’s the advantage of being well-balanced?
Not letting the smallest thing bother you.
Chassis.
Perhaps the most efficient
way of overcoming everyday
obstacles is to rely on one’s
own experience. No one
knows that better than our
own chassis engineers.
