Porsche Traction Management
(PTM) on the Cayenne Diesel and
Cayenne S Hybrid.
The Cayenne Diesel and Cayenne S
Hybrid feature a permanent all-wheel
drive system with self-locking centre
differential. This provides a standard
torque split of 60 % to the rear and
40 % to the front. If one of the wheels
is about to lose grip, the self-locking
centre differential transmits the torque
to the axle offering the highest level of
traction.
The ASR and ABD systems
work in the same way as in the PTM on
the Cayenne, Cayenne S, Cayenne GTS

and Cayenne Turbo.
On the Cayenne Diesel and Cayenne S
Hybrid, PTM also enables variable distribution of engine torque to the rear
wheels, thereby enhancing steering pre
-
cision and driving dynamics. Specifically,
this means that when entering a corner
at high speed, moderate brake pressure
is applied to the inside rear wheel.
This supports the steering motion of
the car, thereby improving its cornering
dynamics.
Standard on the Cayenne Diesel and
Cayenne S Hybrid.
Downhill assistance.
A standard feature on all Cayenne models,
Porsche Hill Control (PHC) provides
downhill assistance by maintaining a
constant rate of speed on extreme downhill gradients. It is activated via a
switch on the centre console. The speed
can be set to bet ween 3 and 30 km/ h.

From urban jungle to the windy wilds.
The Cayenne is perfectly at home on any terrain.
Off-road capability.
Steep ascents leading to snow- covered
mountain lodges, boggy ground or
muddy, loose surfaces – all situations
that the Cayenne handles superbly with
intelligent all-wheel drive. The drive
systems featured on the Cayenne models
deliver exceptional torque. For plent y of
power on tap. On any terrain.
Operating concept.
With the help of Porsche Traction
Management (PTM), the Cayenne can
cope with even the most demanding
off-road scenarios. Simply move the
main off-road control on the centre

console forward or backward to select
one of up to three off-road modes
(depending on the model). Available
on the Cayenne, Cayenne Diesel,
Cayenne S, Cayenne GTS and Cayenne
Turbo, this
function readies the car for
off-road use or reverts the set ting to
normal road driving.
In Off-road Mode 1, for example, the
maps for all relevant systems, e.g. ABS,
are adapted to provide optimum traction.
In addition, High Level I is selected
on vehicles featuring air suspension
with PASM. If that ’s not enough, the air
suspension can be raised further to
High Level II to increase the approach/
departure angle and wading depth.
1)
Push the off-road control forward again
on the Cayenne, Cayenne S, Cayenne GTS
and Cayenne Turbo to activate Off-road
Mode 2 – for even greater traction on difficult terrain, the multi-plate clutch can
be fully locked.
The electronically variable rear diffe
r-
ential on the optional Porsche Torque
Vectoring Plus (PT V Plus, p. 56) is inte -
grated within the all-wheel drive system.
This automatically ensures the optimum
distribution of drive torque on particular -
ly uneven surfaces. If one of the rear
wheels begins to slip, the rear differential
varies the amount of torque transmit ted
through each drive shaft, thereby restor -
ing traction. In Off-road Mode 3, the rear
differential can be manually locked using
the main off-road control. Then both
rear wheels receive the same amount of
torque, regardless of surface conditions.
The optional PDCC (p. 55) enables greater wheel articulation in all three
modes, improving traction still further.
For effective prevention of damage to the
underside of the car, all Cayenne models
can be equipped with optional off-road
underbody protection comprising rock
rails with integrated skid plates, a
reinforced engine-bay guard, additional
protection for fuel tank and rear axle,
and a second towing lug.
1) The Cayenne GTS has a steel -spring spor ts suspension with a 24 mm reduction in ride height (20 mm reduction with optional air suspension). This will lead to restricted capabilit y when driving of f road.

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.

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.

Making headway without getting in a spin.
An approach we thoroughly support.
Porsche Torque Vectoring Plus
(PTV Plus).
A system for enhancing driving dynamics
and stability, PTV Plus offers variable
distribution of engine torque to the rear
wheels and electronically controlled rear
differential. Depending on the steering
angle, steering speed, throttle pedal
position, yaw velocit y and vehicle speed,
PT V Plus optimises steering response
and precision by applying brake pres -
sure to the left or right rear wheel, as
r equired. Specifically, this means that when enter
-
ing a corner at high speed, moderate
brake pressure is applied to the inside
rear wheel. This transfers drive torque to
the outside rear wheel which supports
the steering motion of the car, thereby
improving its cornering dynamics.
At slow and medium speeds, PT V Plus
considerably enhances agility and steer -
ing precision. At high speeds, during
fast cornering and under wheel spin, the
electronically controlled rear differential
ensures additional stabilit y. Also on
variable-grip surfaces, in the wet and on snow, PT V Plus – combined with Porsche
Traction Management (PTM, p. 47) and Porsche Stabilit y Management (PSM, p. 68)
– provides a major contribution to active
safety.
In off-road terrain, PT V Plus reduces
wheel spin on the rear wheels – even when towing heav y trailer loads. The
electronically controlled rear differential
can be fully locked using the off-road
control on the centre console.
Optional for the Cayenne, Cayenne S,
Cayenne GTS and Cayenne Turbo.
Porsche Active Suspension

Management (PASM).
PASM is an electronic damping control
system. It offers continuous adjustment
of individual damping forces based on
current road conditions and driving st yle.
During performance driving or heav y off-
road use, there is an increased tendency
for the body to sway. PASM prevents
this from happening, thereby improving
stability and occupant comfort. PASM
has three setup modes: ‘Comfort ’,
‘Normal’ and ‘Sport’.
Porsche Torque Vectoring Plus (PTV Plus)
Whichever one you select, the system
uses a series of sensors to monitor the
movement of the body. It also gathers
data on lateral acceleration, steering
angle, brake pressure and engine torque
and modifies the damping force on each
individual wheel in accordance with the
selected mode.
PASM remains active at all times. It
automatically adapts to the prevailing
driving conditions, enabling greater
car control and improving comfort and
safety.The Cayenne GTS is the only model in the
range to feature a steel-spring suspension

with a 24 mm reduction in ride height
including PASM. For a lower centre of
gravit y and even closer contact with the
road.
Optional for the Cayenne, Cayenne
Diesel, Cayenne S, Cayenne S Hybrid.
Standard on the Cayenne GTS.

Standard on the Cayenne Turbo:
air suspension with PASM.

A range of other wheel options in various
sizes (up to 21 inches in diameter) is
available for all models.
Ty r e s .
All t yres have been optimised with regard
to driving performance, handling, rolling
resistance and weight. They also provide
great potential for reducing fuel consump-
tion and emissions. The three basic com -
ponents of the t yre have been enhanced –
the rubber compound, tread design and
the architecture of the substructure. This
reduces rolling resistance and fuel con -
sumption.
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 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
