Drive
Maximum freedom requires total control.
Electronic engine management.
The electronic engine management
system provides coordinated
regulation of all engine functions
and associated systems in all
operating conditions.
The basic principle of engine
management is simple. Throughout
each journey, the system monitors
a range of input data and compares
it with corresponding sets of
reference values (‘maps’). Key
engine functions, such as ignition
and fuel injection, can be seamlessly
and automatically adjusted. The
results: optimum fuel economy and
lower emissions as well as greater
power and torque.One of the most important systems
controlled by engine management
is the electronic throttle, a
prerequisitefor Porsche Stability
Management
(PSM). Other major
functions include on-board diagnos-
tics and cylinder-specific knock
control featuring automatic compen-
sation for changes in fuel quality.
On the Cayenne, Cayenne S
and Cayenne GTS, the engine
management system controls
the variable-tract intake manifold.
On the Cayenne Turbo, it regulates
the turbo boost pressure.

Chassis
Exceptional power requires accurate direction.
Steering.Tough for off road, light for the track, stylish for any terrain.
Wheels.
The electrically adjustable steer-
ing column has a driver-selectable
‘Easy Entry’ function, which raises
the steering wheel towards the
dashboard whenever you enter
or leave the car. The comfort and
sports seat options (standard on
Cayenne GTS and Cayenne Turbo)
have a comfort memory package
that stores your preferred
wheel position as well as seat
and exterior mirror settings.
The steering column consists of
multiple collapsing sections linked
by three universal joints. A special
deformation element offering
70 mm of travel provides a high
level of safety in the event of front
impact.
Servotronic.
Servotronic is a speed-sensitive
power steering system available
as an option on all Cayenne
models.
At higher speeds, the steering
becomes firmer, inputs are more
precise and driver comfort is
greatly enhanced.
At lower speeds, it enables easy
manoeuvrability and parking. For optimum manoeuvrability, on
and off road, all Cayenne models
have variable-ratio steering
and special valve settings on
the power-steering system. Lock-
to-lock travel is a modest
2.65 turns, while the turning
circle is just 11.7 metres.
The steering wheel can be adjusted
by 50 mm for reach and 40 mm
for height. Both adjustment options
are electrically assisted on
the Cayenne GTS and Cayenne
Turbo. Electric adjustment is also
available as an option on the
Cayenne and Cayenne S as part
of the optional comfort or sports
seat package (each with comfort
memory package). The optional
padded steering wheel (standard
on Cayenne GTS) brings added
sporting style to each model.
the multi-purpose display in the
instrument cluster. Standard wheel fitments are as
follows: 17-inch Cayenne alloys on
the Cayenne, 18-inch Cayenne S II
on the Cayenne S, 21-inch
Cayenne Sport on the Cayenne
GTS and 19-inch Cayenne Design
on the Cayenne Turbo.
For a more personal touch, you
can choose from a range of
wheel options (see page 160).
Tyre Pressure Monitoring
(TPM).
The optional TPM warns of any
drop in pressure via the on-board
computer display. In addition,
the driver can check the individual
pressures in all four wheels via

maximum ground clearance:
271 mm. Selectable at speeds
of up to 30 km / h (19 mph) for
extreme off-road use. Maximum
approach angle on gradients: 31.8°.

maximum ground clearance:
191 mm. Suspension is firmer
and drag is reduced. Automatically
selected above 125 km / h
(78 mph).

6. Loading Level.
54 mm below Normal Level,
maximum ground clearance:
161 mm. Lowest available setting,
enabling easier loading of vehicle.
Only selectable when vehicle
is stationary. When setting off,
suspension automatically reverts
to Normal Level.
Cayenne GTS.**
The Cayenne GTS is 20 mm lower
than the other Cayenne models
at Normal Level, High Level I and
High Level II, and 5 mm lower at
Low Level I. All other ride-height
settings (Low Level II and Loading
Level) are the same.
The Cayenne Turbo has an air
suspension system featuring
self-levelling, ride-height control
and PASM as standard. The
system is optional on the Cayenne,
Cayenne S and Cayenne GTS*.
On the Cayenne GTS, there’s a
20-mm reduction in ride height
at Normal Level, High Level I and
High Level II.
The self-levelling facility maintains
a constant ground clearance,
regardless of vehicle load. With
the ride-height control on the
centre console, you can easily
vary the ground clearance. The
current ride-height setting is
indicated in the instrument cluster
and on a separate LED display
on the centre console.
** PASM standard on Cayenne GTS.
** With air suspension.

Braking system.
All Cayenne models have internally
vented discs all round. This simple
yet highly effective design ensures
consistent brake performance.
The front disc dimensions
(diameter/thickness) are 330 mm /
32 mm on the Cayenne, 350 mm /
34 mm on the Cayenne S and
Cayenne GTS, and 380 mm /
38 mm on the Cayenne Turbo.
All models have six-piston monobloc
aluminium brake calipers at the
front and four-piston equivalents
at the rear. The Cayenne Turbo
has a new and more powerful
braking system to offset its higher
performance. The fixed calipers on
the Cayenne Turbo are noticeably
larger and have a striking red
paint finish. The calipers on the
Cayenne GTS are also red, while
the Cayenne S has silver and the
Cayenne black. Braking is assisted

All brake pads are fitted with
individual wear sensors. When new
pads are required, a warning light
is illuminated in the instrumentcluster. The brake lines serving
each of the rear calipers feature
special off-road protection
against rocks and other debris.
