standard on the new Cayenne
Turbo. Optional for all other
Cayenne models.
Porsche Dynamic Chassis
Control (PDCC).
Available as an option in conjunc ­
tion with air suspension, Porsche
Dynamic Chassis Control (PDCC)
is an active anti ­roll system
that further enhances the extra­
ordinary road holding and
precision handling of the new
Cayenne models.
PDCC anticipates and significantly
reduces lateral body movement
when cornering. This is achieved
with the aid of the active anti ­roll
bars featuring hydraulic swivel
motors on the front and rear
axles. The system responds to
the current steering angle and
lateral acceleration by producing
a stabilising force that precisely
negates the swaying force of the
body. The benefits are greater agilit y
at every speed, more responsive
steering, stable load transfer
characteristics and enhanced
occupant comfort. When off
­road
mode is selected via a switch in
the centre console, this allows
the t wo halves of each anti ­roll
bar to rotate further in opposition
to each other. This in turn enables
greater wheel articulation and ensures that each individual
wheel has more contact with
the ground, improving traction
on uneven surfaces.
Optional for the new Cayenne,
new Cayenne S and new
Cayenne Turbo.

The new Cayenne models can be
equipped with an air suspension
system featuring self ­levelling,
ride ­height control and PASM – for
enhanced driving dynamics and
comfort. The self ­levelling facilit y
maintains a constant ground clear ­
ance, which can easily be adjust ­
ed using the ride ­height control
on the centre console:

high­mounted upper arms are now
in aluminium. This axle design
ensures accurate wheel location,
greater agilit y and minimal inter ­
ference on uneven surfaces.
The subframe is secured on large
rubber mountings that reduce
road noise to a minimum. It is
also specially constructed to
increase stabilit y. For enhanced comfort and even greater active
and passive safet y. In the event
of an impact, the subframe
deforms in a predefined manner.

Rear axle.
The rear axle features multi
­link
suspension. Ideal for performance
road and track use, it also copes
well with the extremely high
towing and carrying loads that
are possible with each Cayenne.
The suspension struts are angled
to allow longer suspension travel
and create a deeper and wider
cargo area. As well as providing
additional space, the car is also
easier to load. The rear axle design minimises
dive and squat under acceleration
and braking. It also improves mid
­
corner stabilit y and compensates
for sudden load transfer. In short:
it enables a more relaxed way
of driving. Examples of intelligent
light weight construction on the
rear axle include hollow drive
shafts.
Steering.
The steering system has been
completed revised and adapted
for a sportier driving st yle.
Around the straight ­ahead pos­
ition, in particular, the ratio is
now more direct. With the variable
steering ratio and special valve
set tings on the power ­steering
system, optimum manoeuvrabilit y
is ensured. The turning circle of
the new Cayenne models is just
11.9 metres.
The steering column itself
consists of multiple collapsing
sections linked by t wo universal
joints and a special deformation
element provides additional safet y
in the event of a front impact. Electro
­hydraulic power steering
is used for the first time on the
Cayenne S Hybrid. The demand ­
driven pump only provides
assistance to the steering as
and when required, thereby

contributing to overall efficiency.
Servotronic.
Servotronic is a speed ­sensitive
power steering system.
At higher speeds, the steering
becomes firmer, inputs are more
precise and driver comfort is
enhanced. At lower speeds, it
enables easy manoeuvrability
and parking.
Standard on the new Cayenne S
Hybrid. Optional for the new
Cayenne, new Cayenne Diesel,
new Cayenne S and new
Cayenne Turbo.

Ty r e s .
All t yres have been optimised
with regard to driving perform­
ance, handling, rolling resistance
and weight. They also provide
great potential for reducing fuel
consumption and emissions. The three basic components of
the t yre have been enhanced –
the rubber compound, tread de­
sign and the architecture of the
substructure. This reduces rolling
resistance and fuel consumption.
Tyre Pressure Monitoring
(TPM).
Tyre Pressure Monitoring (TPM)
provides early warning of any
drop in pressure via the on
­board
computer display. In addition, the driver can quickly
and easily check the individual
pressures in all four wheels via
the multi
­purpose display in the
instrument cluster. Standard on the new Cayenne
Turbo. Optional for all other
new Cayenne models.
Wheels.
All of the wheels for the new

Cayenne models have been
specifically designed to reflect
the character of the car – and
convey it to the road.
Standard on the new Cayenne
and new Cayenne Diesel: the
new 18 ­inch Cayenne wheel.

All Cayenne models have internal­
ly vented discs all round, ensuring
consistent performance during
heav y use. The front disc dimen ­
sions (diameter/thickness) are
350 mm/34 mm on the new

Cayenne and new Cayenne Diesel,
360 mm/36 mm on the new
Cayenne S and new Cayenne S
Hybrid, and 390 mm/38 mm on
the new Cayenne Turbo. All models have six
­piston
monobloc aluminium brake
calipers at the front and four ­
piston equivalents at the rear.
The calipers are black on the new
Cayenne and new Cayenne Diesel
and silver on the new Cayenne S
and new Cayenne S Hybrid. On
the new Cayenne Turbo, they
feature a striking red paint finish. Braking is assisted by a tandem
booster and large brake master
cylinder. Further assistance is
provided by PSM (p. 66).
The pads are equipped with
individual wear sensors. When
new pads are required, a
warning light is illuminated in
the instrument cluster.
Electric parking brake.
Manually activated and deactivat ­
ed, the electric parking brake
releases automatically as you drive
off.
Automatic hold function.
With the automatic hold function,
you can pull away on the flat or a
slope without ever rolling back.
The system automatically detects
when the vehicle has come to a
halt on an uphill gradient. PSM then
maintains the brake pressure at all
four wheels for a brief period to
prevent the vehicle from moving in
the opposite direction.
Braking systems.
Porsche brakes are renowned
worldwide as the benchmark in
performance
and durabilit y.
Equipped with new braking
systems, the new Cayenne
models continue this tradition.
The larger brakes of fer excellent
deceleration – even when the
car is fully laden with five adult
occupants, a full complement
of luggage and a braked trailer
load of up to 3,500 kg (Cayenne
with manual gearbox: 2,700 kg).
Outstanding brake performance.

Porsche Ceramic Composite Brake (PCCB)
To do this, the engine manage­
ment system adjusts the gener­
ator current depending on the
brake pedal position, recovers
part of the kinetic energy and
stores it in the bat tery. When

the pressure on the brake pedal
exceeds a certain threshold, the
brakes are applied.
Porsche Ceramic Composite
Brake (PCCB).
Available as an option on all new
Cayenne models, the Porsche
Ceramic Composite Brake (PCCB)
has already proven its abilit y to
cope with the harshest require ­
ments of the racetrack. It is
available in conjunction with
20 ­inch wheels or larger for the
Cayenne Turbo and with 19 ­inch
wheels or larger for all other
Cayenne models.
The cross ­drilled discs are
generously proportioned: on
the Cayenne Turbo they have
a diameter of 410 mm at the

front and 370 mm at the rear,
while on all other models they
measure 390 mm and 370 mm,
respectively.
The discs are made from a
specially treated carbon ­fibre
compound that is silicated
in a high ­vacuum process at
approximately 1,700 °C. The
resulting material is not only

much harder than cast iron, it
is also more resistant to heat. Even at high temperatures, the
thermal resistance of the PCCB
disc ensures outstanding dimen
­
sional stabilit y. The ceramic
material is totally resistant to
corrosion and offers excellent
acoustic damping properties.
PCCB enables shorter braking
distances – no mat ter how tough
the driving conditions. The pedal
response is fast and precise with
only moderate input required. Excellent fade resistance ensures
greater balance when slowing
from high speed.
The key advantage of PCCB is

a total weight saving of approxi ­
mately 50% compared with
equivalent cast ­iron discs. As well
as enhancing performance and
fuel economy, the unsprung and
rotating masses are lightened.
The results: greater comfort
and road ­holding on uneven road surfaces plus bet ter handling
and agility.
Optional for all new Cayenne
models.
Recuperation.
The electronic engine manage ­
ment system on the new Cayenne S
Hybrid controls the braking
process so that, when the brake
pedal is actuated, as much
expended energy as possible
can be harnessed by the electric
machine’s generator and stored
in the 288 ­Volt nickel metal
hydride (NiMH) bat tery. This is
referred to as recuperation.

PSM has three additional func­
tions that help reduce braking
distances. If the throt tle pedal
is released suddenly, PSM

automatically readies the braking
system. The pressure in the
brake lines is marginally increased,
bringing each of the pads into
light contact with the correspond ­
ing disc. If the driver goes on
to apply the brakes, the calipers
respond more quickly and the
braking distance is reduced. In an emergency stop – i.e. when
the pressure on the brake pedal
exceeds a certain threshold –
the brake assist function uses the
PSM hydraulics to apply maximum
braking force at all four wheels.
For added safet y, the system
also readies the brakes whenever
a decreasing distance to the
vehicle in front is detected. The
optional adaptive cruise control
and PSM interact to prefill the
brakes.
Even if adaptive cruise control is
inactive, the system registers the
speed of the vehicle in front and
automatically readies the braking
system. In addition, the system
alerts the driver to the decreasing distance by briefly tugging on
the brakes.
PSM also features a trailer
stabilisation function – for a
significant contribution to car
and trailer safet y.
Within the laws of physics, it
compensates for load transfer
caused by throt tle and brake

inputs up to the maximum degree
of lateral acceleration. It also en ­
hances the car’s driving dynamics
and directional stabilit y when
accelerating on inconsistent road
surfaces.
Other features include a special
control strategy in the ABS
for braking on loose surfaces.
By briefly locking the wheels, a wedge is formed ahead of each
t yre which provides additional
purchase to help slow the car,
e.g. on gravel or snow.
For a more involving driving

experience, PSM can also be
disabled, but remains active in
the background.
Standard on all new Cayenne
models.
accele

ration of the car. Using
this information, it is possible to
calculate the actual direction of
travel at any given moment. If
the car begins to oversteer or
understeer, PSM applies selective
braking on individual wheels to
restore stabilit y. If necessar y,
PSM can also intervene in the
engine management system to
temporarily modif y the amount of
drive transmit ted to the wheels.
Porsche Stability Management
(PSM).
Porsche Stabilit y Management
(PSM) is an electronic control
system that uses a range of
functions – including anti ­lock
braking (ABS) – to help stabilise
the vehicle (and trailer, if fit ted)
in hazardous road scenarios.
Throughout each journey, sensors
monitor the direction, speed,

Pressure Monitoring (TPM), which
is also available as an option. On the new Cayenne S Hybrid, the
display also provides information
about the energy management.
Oil pressure, oil and coolant
