Six-speed manual gearbox.
The six-speed manual gearbox on the
Cayenne has been specifically adapted
for the demands of high-performance
use. The gear lever throw is short and
precise, and each of the six ratios has
been selected for optimum progression
through the gears. As the centre console
rises to meet the dashboard, the gear
lever is close to hand – for an even more
engaging drive.
The standard upshift display in the
instrument cluster helps to reduce fuel
consumption further still. Eight-speed Tiptronic S is also available
as an option on the Cayenne in conjunc
-
tion with the auto start/stop function.
Standard on the Cayenne.
Eight-speed Tiptronic S.
The outstanding feature of the eight-
speed Tiptronic S is a particularly wide
ratio spread. 1st gear is designed for
optimum acceleration when pulling away
and greater performance when tackling
ascents and towing loads in off-road
terrain. Top speed is reached in 6th gear
(in 7th gear on the Cayenne Diesel). The
remaining upper gears are used to lower
the revs at high speed, thereby enhanc -
ing fuel economy and occupant comfort. On the motorway in particular, driving

at low revs will significantly reduce the
noise level inside the vehicle.
In automatic mode, the driver can influ -
ence gearshifts on the Tiptronic S using
the throt tle and brakes alone. Tiptronic S
automatically adapts the gearshift points
for performance driving – equally, if a
more defensive driving st yle is detected,
the system selects a gearshift point that
offers maximum fuel economy. Under
heav y braking, Tiptronic S shifts down to
maximise engine braking.
An electric pump is used to maintain the
required pressure of the transmission fluid,
e.g. to transmit high levels of torque
at
lower engine speeds. The standard sports steering wheel in
conjunction with Tiptronic S has two
ergonomic switches for manual gear
changes. One press forward with the
thumb and Tiptronic S shifts up. One

pull backwards with the index finger and
Tiptronic S shifts down. Either the right
or left-hand switch can be used. The
result: an even more dynamic response
when changing gear.
Standard on the Cayenne Diesel,
Cayenne S, Cayenne S Hybrid,

Cayenne GTS and Cayenne Turbo.
Optional for the Cayenne.

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.

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.

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.

The concept behind every car we build
is based around the pursuit of perform -
ance. This has been the case since
1948. Another of our traditional core
values is efficiency. At Porsche, we are
continually striving to find a successful
balance between the two.
This is achieved using advanced engine
concepts featuring technologies such
as DFI (p. 40), VarioCam Plus (p. 39),
the auto start /stop function (p. 38),
the parallel full hybrid drive (p. 28) and
consistent lightweight construction. Weight reduction is a key aspect of our
design philosophy derived from our rich
racing heritage. Part of our R&D Centre,
the Motorsport Department is located in
Weissach where it shares premises with
the Automotive Industry Exhaust Emission
Centre (ADA). Just a
coincidence? We call
it symbiosis.
In practice: the Cayenne is up to 185 kg
lighter, depending on the model.
1) We
have achieved this through the use of
new, innovative weight-saving materials,
the development of new production technologies and functionalities, and a
series of concept modifications. This

has enabled us to halve the weight of
the tailgate, for example. Innovative
materials are also a feature of the axle
construction, with steel being replaced
where possible by lightweight alterna -
tives such as aluminium and plastic.
The benefits for the driver: greater agilit y
and driving dynamics – with lower fuel
consumption. Efficiency at its best.
Great achievements are something to be proud of.
Even more so if they benefit the world around you.

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.
