The 911 | Chassis
To steer a true course, you sometimes have to be able
to take the rough with the smooth.
The axles.
Standard suspension.
The front axle is equipped with
McPherson strut suspension and
the wheels are located using a
high-precision arrangement of
longitudinal and transverse links
and reinforced wheel bearings.
The benefits on the road are
precision wheel guidance, excel-
lent straight-line stability and
superior handling characteristics.
The rear axle has a race-derived
multi-link suspension, following
the LSA concept (Lightweight,
Stable, Agile) for exceptional
driving dynamics. The axle
kinematics significantly reduce
the compression of the vehicle’s
suspension under acceleration.
Lightweight spring struts with
aluminium dampers on the rear
axle help to maximise handling
agility.
This lightweight construction
keeps the vehicle gross weight
and the weight of the unsprung
masses low. The chassis allows
for safe manoeuvring, even at
high speeds. The pitching of
the body when pulling away and
braking is minimal, as is body
roll in corners. Rolling noises
and vibrations are also kept to a
minimum.
Steering.
The power steering is sensitive
and precise, providing excellent
contact with the road and minimal
steering effort by sportscar
standards. It offers steering
precision comparable with a
racecar – even on those relaxing
drives.
A special feature is the variable
steering ratio. Around the straight
ahead position, such as during
motorway driving, the ratio is less
direct. The risk of losing control
of the wheel at high speed is
reduced, with no loss of agility
or feedback.
When the steering wheel is turned
harder, the ratio becomes more
direct, allowing for easier corner-
ing and parking. The car has
a turning circle of just 10.9 m.
