Shedding weight.
Adding agility, economy and comfort.

Chassis.
Weight reduction.
The axle concept on the Cayenne models
features consistent lightweight con -
struc
tion. The results: enhanced driving
dynamics, lower fuel consumption and
optimum occupant comfort.
Front axle.
The chassis on the Cayenne models
offers a direct response – for a more
rewarding driving experience. The wish -
bones on the subframe-mounted front
suspension with high-mounted upper
arms are in aluminium. This axle design
ensures accurate wheel location, greater
agility and minimal interference 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
stability. 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 suspen -
sion. 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 suspen -
sion 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 stability and
compensates for sudden load transfer. In short: it enables a more relaxed

way of driving. Examples of intelligent
lightweight construction on the rear
axle include hollow drive shafts.
Steering.
The steering system has been com pletely
revised and adapted for a more immediate
response and greater driving dynamics.
Around the straight-ahead pos ition, in
particular, the ratio is now more direct.
With the variable steering ratio and spe -
cial valve settings on the power-steering
system, optimum manoeuvrability is
ensured. The turning circle of the Cayenne
models is just 11.9 metres.
The steering column itself consists of
multiple collapsing sections linked by two
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.
Power steering Plus.
Power steering Plus 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 Cayenne S Hybrid.
Optional for all other Cayenne models.

Let us show you more.
Air suspension.
The Cayenne models can be equipped
with an air suspension system featuring
self-levelling, ride-height control and
PASM (p. 57)
1) – for enhanced driving
dynamics and comfort. The self-levelling
facility maintains a constant ground
clearance, which can easily be adjusted using the ride-height control on the
centre console.
Air suspension with PASM standard
on the Cayenne Turbo. Optional for all
other Cayenne models.

Steel-spring suspension.
The steel-spring suspension meets
high-level requirements in terms of per
-
formance, driving pleasure and off-road
capability. Consistent lightweight con -
struction – e.g. through the increased
use of aluminium – results in improved
driving dynamics, greater fuel economy
and enhanced comfort. The steel-spring suspension with a 24 mm reduction in
ride height on the Cayenne GTS is
designed to
deliver one thing above
all else: sports performance.
Standard on the Cayenne, Cayenne
Diesel, Cayenne S, Cayenne S Hybrid
and Cayenne GTS.
Porsche Dynamic Chassis Control
(PDCC).
Available as an option in conjunction
with air suspension, Porsche Dynamic
Chassis Control (PDCC) is an active

anti-roll system that further enhances the
extraordinary road holding and precision
handling of the Cayenne models. PDCC
anticipates and significantly reduces
lateral body movement when cornering
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 bene-
fits are greater agilit y at every speed,
more responsive steering, stable load transfer characteris
tics and enhanced
occupant comfort. When off-road mode
is selected via a switch on 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 articu lation and
ensures that each individual wheel has
more contact with the ground, improving
traction on uneven surfaces.
Optional for the Cayenne, Cayenne S,
Cayenne GTS and Cayenne Turbo.

Driving with foresight.
Quite literally.
Active safety.
It’s always a pleasure taking corners
in a Porsche. Especially when they’re
now so visible at night. The striking
lighting arrangement is also instantly
recognisable.
Automatic headlight activation.
The headlights are automatically
switched on when darkness sets in
or when driving through a tunnel in the
daytime. Other features include an auto -
matic switch-off and ‘Welcome Home’
function – when you arrive at a destin -
ation after dark, the headlights remain
illuminated for a user-defined period,
lighting your path from the car.
Standard on all Cayenne models.
Halogen main headlights.
The projector-beam halogen main head -
lights feature automatic static range
control and reflection high-beam lights –
for optimum illumination of the road.
Standard on the Cayenne, Cayenne
Diesel, Cayenne S and Cayenne S
Hybrid.
Bi-Xenon main headlights with
Porsche Dynamic Light System (PDLS).
The Bi-Xenon main headlights – which
also have a black surround on the
Cayenne GTS – feature halogen auxiliary
headlights, integrated headlight cleaning
and automatic dynamic range control.
This provides more uniform illumination
of the road in both dipped and high-beam
mode. The dynamic cornering light function
swivels the main headlights towards the
inside of a bend based on the current
steering angle and road speed. The static
cornering lights activate the auxiliary
headlights in order to illuminate more of
the road in tight bends and turns.
PDLS also features speed-sensitive
headlight control and an adverse
weather function, which is activated

in conjunction with the rear foglight –
for even greater safet y, not just at night
and during cornering.


Standard on the Cayenne GTS and
Cayenne Turbo. Optional for all other
Cayenne models.

Porsche Dynamic Light System Plus
(PDLS Plus).
PDLS Plus offers t wo additional func -
tions: high Beam Assistant recognises
oncoming vehicles and automatically
switches the headlights from high beam
to dipped beam.
As you approach a crossing, Intersection
Assistant activates the left and right
indicators, making the beam of light
broader and shorter. This improves illu -
mination of the area directly surrounding
the vehicle, making the driver more
aware of what ’s going on around him.
Optional for all Cayenne models.
Daytime running lights.
Fit ted as standard on all Cayenne
models: LED day time running lights. On the Cayenne, Cayenne Diesel,
Cayenne S and Cayenne S Hybrid, these
are arranged horizontally in the front light
units, whereas on the Cayenne GTS and
the Cayenne Turbo each main
headlight
unit has four LED spotlights. Day time
running lights improve safet y in the
day time as they make you more visible
to other road users.
Taillights.
LED technology is used for all functions
on the rear light modules. For an ultra-
fast response and greater luminance.
In
short: for greater safet y. In an emer -
gency stop, the adaptive LED brake
lights on the Cayenne models pulsate
to alert the traffic behind more quickly
to a critical situation. The high-level third
brake light is integrated into the roof
s p o i l e r.

Recuperation.
The electronic engine management sys -
tem on the 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 in gen-
erator mode and stored in the 288-volt
nickel metal hydride (NiMH) bat tery. This
is referred to as recuperation. To do this,
the engine management system adjusts
the generator 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 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 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 dimensional stability. 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 approximately 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 better
handling and agility.
Optional for all Cayenne models.

Exhaust emissions.
The Cayenne models are all equipped
with the latest emissions technology. As
a result, they comply with the European
exhaust emissions standard, EU 5.
Whatever the class, every Porsche
combines high performance with com -
paratively moderate emissions. On the
Cayenne models, this is achieved using
advanced drive concepts – from petrol
and diesel engines to our parallel full
hybrid drive. This is further aided by the
rapid warm-up cycle of the catalytic
converters. The optimum operating tem -
perature is reached earlier so emissions
are reduced sooner when starting from
cold. On the petrol- engined and hybrid models,
another important feature is the use of
t win oxygen-sensor circuits. Each bank of
cylinders has a separate control system
which the engine management system
uses to establish the optimum amount of
fuel – for effective emissions control.
The exhaust-gas recirculation on the
Cayenne Diesel routes part of the exhaust
gas back into the combustion process,
resulting in lower peak com bustion tem-
perature and therefore lower nitrogen
oxide emissions. An oxidation catalyst
also forms an integral part of the process
along with a diesel particulate filter.
Porsche engines.
Performing for today – and the future.
Fuel and fuel economy.
Increasing performance while enhancing
fuel economy. The Cayenne comes in a
choice of three different drive systems,
each featuring state-of-the-art technol -
ogy for high efficiency and relatively low
fuel consumption. The petrol-engined
models already operate on fuels with

an ethanol content of up to 10 %. This
further improves the carbon dioxide
balance since the plants grown for the
production of biofuels absorb carbon
dioxide from the atmosphere. As you
can see, for the benefit of the environ
-
ment, we are continually working on
making our cars more efficient – as

well as compatible with alternative
fuels. While ensuring that they remain
one thing: a thoroughbred Porsche.
Fuel system.
We have also applied the highest stand -
ards to our petrol- engined models in
order to protect the environment from
fuel evaporation. The non-return fuel
supply system provides a considerable
reduction in vapour emissions. The lines
carrying vapour are made from multi-
layer plastics. A large active-carbon
filter and multi-layer plastic fuel tank help
reduce evaporation still further.

2 emissions and efficiency class data, please refer to pages

Noise.
As paradoxical as it may seem, the
distinctive Porsche sound is also created
by what you don’t hear – the absence of
unwanted noise. Naturally, its main origin
is deep within the engine. But that ’s
not all. Our holistic approach to vehicle
design also extends to the acoustics.
Which is why we’ve optimised them for
the entire car.
To minimise ‘play’ between components,
we’ve used stronger, lighter and more
temperature-resistant materials. This
reduces mechanical noise. Large-volume
silencers and air intake manifolds also
help to eliminate noise – throughout the
life of the car.
Tyre noise has been drastically reduced
in collaboration with our official t yre
partners. Wind noise levels have also
been lowered thanks to aerodynamic
refinements. All that remains is a sound that is pure
Porsche.
Servicing.
With lengthy service intervals and long-
life components, vehicle maintenance is
kept to a minimum. In the case of the oil
filter, for example, all that ’s replaced is
an easily recyclable paper element. The
oil filter casing remains on the car.
All moving parts inside the engine are
fully self-adjusting. The valve clearances,
for instance, feature automatic hydraulic
control.
Thanks to single-spark coils on each of
the cylinders, the entire ignition system
on the petrol-engined models, with

the exception of the spark plugs, is
maintenance-free.
These modest service requirements
mean less waste disposal and fewer demands on natural resources. They

also lower the cost of ownership while
keeping your car on the road.
Service intervals for the Cayenne models
are dependent on a range of factors,
including local fuel quality. For full details
of service intervals in your country, please
consult the relevant price list or contact
your Porsche Centre.
Materials and recycling.
Owning a Porsche should be a lasting
pleasure with minimal impact on the
environment. This Porsche principle
can be summed up in one word: sustain -
abilit y. The light weight exhaust on the
Cayenne models, for example, is con -
structed from long-life stainless steel.
Every Porsche model is entirely free of
CFCs and components manufactured
using CFCs. All legal requirements in
respect of recoverability are fulfilled.
Materials are clearly labelled for
subsequent identification and sorting

to facilitate efficient recycling.
While more than 95 % of the car can be
recycled using current technologies, the
chances are your Cayenne may never
need
recycling at all. After all, t wo thirds
of all the cars we have ever made are
still on the road today.

ed, the GSM antenna on the mobile
phone is disabled to prolong battery
life and the external vehicle antenna
is utilised instead. Depending on the
phone model, you can access contact
details on the mobile phone SIM card
and internal memory and perform all
operations via PCM, voice control or
the multifunction steering wheel, which
means your phone can remain in your
pocket. In addition, the telephone module
enables you to establish a Bluetooth
®
connection to a mobile phone that only
supports the Hands-Free Profile (HFP).
In this case, the GSM connection to
the mobile phone network is via the
handset antenna. PCM acts as a hands-
free system.
A cordless handset with keypad and
display is also available as an option.
This is stowed in the centre console.
However, the handset cannot be used
to establish a Bluetooth
® connection
using the Hands-Free Profile (HFP).

Optional for all Cayenne models.

Do you wish to get to the point – or your
required destination – more quickly? All
you have to do is say so. The optional
voice control system with whole-word
recognition is at your command – without
the tedious task of voice learning. This
means that the voice control system can
recognise the input of an entire address
for a navigational destination, telephone
book entries or radio station names.
Audio prompts make voice inputs even
simpler. You can also browse through
lists by voice command.

Optional for all Cayenne models.
Mobile phone preparation.
With this optional preparation, you can
establish a Bluetooth
® connection with
a mobile phone that only supports the
Hands-Free Profile (HFP) and use the
