Pitching of the body when pull
ing away and braking is minimal,
as is body roll in corners. Tyre
noise and vibrations are simi
larly reduced. Driving stabilit y,
on the other hand, is extremely
high.
This purposeful lightweight
construction keeps the vehicle
gross weight and the weight of
the unsprung masses low, while
the suspension itself allows
even high
speed manoeuvres
to be executed smoothly and
s a fe l y.
Wheels.
As standard, the new
911 Carrera GTS models are
fit ted with 19 inch RS Spyder
wheels with centre spokes
with a black painted finish.
The main feature of these forged
aluminium alloy wheels is the
central locking device – a clear
reference to the world of
motorsport. Compared with the
conventional five bolt wheel
connection, it offers enhanced
driving dynamics and perform
ance thanks to the reduction in
rotating masses.
Tyre Pressure Monitoring,
available as an option, sends
warnings to the on board com
puter’s display screen in the
event of a gradual or sudden
loss of pressure.
Porsche Active Suspension
Management (PASM).
Included as standard equip
ment, Porsche Active Suspen
sion Management (PASM) is
an electronic active damping
system. It of fers continuous
adjustment of the damping
force on each wheel, based on
the current driving situation
and your driving st yle.
At the press of a button, the
driver can select bet ween t wo
different modes: ‘Normal’, which
is a blend of performance and
comfort, and ‘Sport ’, where
the setup is much firmer. The
balance bet ween comfortable
and uncompromisingly sporty is struck more ef fectively than
with a conventional chassis. The
PASM control unit evaluates the
driving conditions and modifies
the damping force on each of
the wheels optimally in accord
ance with the selected mode.
Sensors monitor the movement
of the vehicle body, for exam
ple, under heav y acceleration
and braking or on uneven roads.
The control unit tunes the damp
ers to the optimum hardness
for the selected mode to reduce
roll and pitch and to increase
contact bet ween each individual
wheel and the road.
PSM computes the actual
direction of motion. If this direc
tion deviates from the desired
course, PSM can, for example,
initiate braking interventions
targeted at individual wheels in
order to stabilise the vehicle.
Porsche Stability
Management (PSM).
PSM, which comes as standard,
is an automatic control system
that stabilises the vehicle at the
limits of dynamic driving per
formance. Sensors continuously
monitor driving direction, speed,
yaw velocit y and lateral acceler
ation. Using this information, Under acceleration on wet or
low
grip road surfaces, PSM
improves traction using the ABD
(automatic brake dif ferential)
and ASR (anti slip regulation)
functions. For a pure, active
driving experience, PSM can
be deactivated but it will auto
19inch RS Spyder wheel with central locking device
matically reactivate if necessar y
for safet y.
PSM comes with t wo additional
functions: precharging of the
brake system, enabling the
maximum braking power of the
911 Carrera GTS to be achieved much sooner; and brake assist,
for maximum deceleration in a
critical situation.
Those who speak in clear
language want clear distinctions.
