2008 PORSCHE CAYENNE air suspension

Chassis
Active prevention of body roll when cornering.
For greater comfort and control.
Porsche Dynamic Chassis Control (PDCC).
PDCC is an active anti-roll system
that anticipates and significantly
reduces lateral body movement
when cornering. It also minimises
oscillation on rippled road
surfaces. As a result, the car
remains stable and easy to
control. This is achieved with the
aid of active anti-roll bars on the
front and rear axles. The system
responds to the current steeringangle and lateral acceleration by
producing a stabilising force that
precisely negates the swaying
force of the body.
The benefits are better traction
and occupant comfort both on
and off the road.For the driver, PDCC provides
greater agility at every speed, more
responsive steering and stable load
transfer characteristics. Combined,
these represent a new benchmark
in steering precision. Performance
and comfort are both improved,
and with them, driving pleasure.
When the low-range gearing is
selected, PDCC automatically
switches to off-road mode.
Essentially, this allows the
two halves of each anti-roll bar
to
rotate further in opposition to
each other. This in turn enables
greater wheel articulation, which
improves traction on uneven
surfaces.Since each wheel has more
contact with the ground, more
drive can be transmitted (see
page 86).Vehicles with PDCC have a
silver finish on the centre
console chassis controls. Among the key objectives of
Porsche chassis design are
optimum road holding and precision
handling. Both of these character-
istics can be further enhanced with
Porsche Dynamic Chassis Control
(PDCC). It is available as optional
equipment on all Cayenne models
in conjunction with air suspension/
PASM (standard on Cayenne Turbo,
optional on all other models).

Off road
Every Porsche is designed and
built to the highest possible
standards – in dynamics, agility,
safety, comfort and everyday
practicality. Combined, the result
is pure driving pleasure. With the
Cayenne models: on any terrain.
All four cars were developed for
the road – and much of the land
beyond. Simply shift the transfer
gearbox into ‘low-range’ mode and
the car is ready for any terrain.
Porsche Traction Management
(PTM) and Porsche Stability
Management (PSM) make a range
of modifications, including auto-
matic
selection of low-range
gearing, a high-traction off-road
chassis
programme (with off-road
ABS and
ABD) and High Level I on
vehicles
with air suspension.
The centre differential, part of
the all-wheel drive system, can
be fully locked for the toughest
conditions.At High Level II, the ground
clearance is increased by a further
30 mm. All models can negotiate
gradients of up to 45° (100 %).
Hill-starts are easy with the Hill
Holder function in Tiptronic S and
Porsche Drive-off Assistant on
vehicles with manual gearbox.

Off-road capability.

Off road
Porsche Hill Control (PHC) uses
engine braking to enable steady
descent on otherwise hazardous
gradients at speeds of up
to 20 km / h (12.5 mph). If one
or more wheels begin to lose
traction, PHC compensates by
applying increased engine braking
on those that retain contact withthe ground. With no need to
adjust braking, the driver can
concentrate fully on steering
the car.
With steel-sprung suspension,
the maximum wading depth is
500 mm.* With the optional air
suspension (standard on the
Cayenne Turbo), the car is secure
to a depth of 555 mm.**
On extremely uneven terrain,
you can smooth your path with
the optional Porsche Dynamic
Chassis Control (PDCC). Featuring
active anti-roll bars, the PDCC
off-road mode is automatically
enabled whenever ‘low-range’
mode is selected. With greater
articulation of each wheel, there
is less unwanted body-roll and
occupant comfort is improved.
PDCC in on-road mode: reduced wheel articulation
PDCC in off-road mode: increased wheel articulation
**Cayenne GTS: 476 mm.** Cayenne GTS with air suspension: 535 mm.

The Cayenne models use power
and performance for more than
just driving pleasure. All four cars
have a large and variable rear
luggage compartment with power
closing tailgate as standard.
An automatic tailgate is available
as an option. The luggage
compartment has a total volume
of 540 litres (VDA), i.e., more than
enough space for up to four large
suitcases. The loadspace floor is
completely flat and the tailgate
sill is low. When the rear seats
are folded flat on vehicles with
sports seats (featuring comfort
memory package), the larger side
bolsters create a slope of approx.
15º relative to the loadspace floor.
Even when the car is fully laden
(see page 188), the self-levelling
air suspension (standard on
Cayenne Turbo; optional on other
models) maintains a constant
ground clearance at front and
rear.
The air suspension package
includes ride-height adjustment,
enabling the car to be lowered
by approximately 54 mm* below
the normal ride level for easier
loading of heavy items. When
moving off, the suspension
automatically reverts to the
standard ride-height setting
(Normal Level).
When the rear backrest is folded
forward, the loadspace expands
to as much as 1,770 litres**
(VDA). Items can be stored out
of view and protected from the
sun using a retractable cover in
a detachable storage cassette.
Two additional storage spaces
(one on vehicles with four-zone
air conditioning) are discreetly
concealed behind the side trim
panels in the luggage compart-
ment (volume may vary depending
on optional equipment).
Even when loaded to the
maximum weight, each Cayenne
model remains agile, responsive
and easy to control.
