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.

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.

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,
yaw velocit y and lateral acceleration of
the car. Using this information, it is pos-
sible 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 necessary,
PSM can also intervene in the engine
management system to temporarily
modify the amount of drive transmitted
to the wheels. PSM has three additional functions that
help reduce braking distances. If the
throt tle pedal is released suddenly, PSM
automatically readies the braking sys
-
tem. The pressure in the brake lines
is marginally increased, bringing each
of the pads into light contact with the
corresponding 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.
Preparing for the road ahead.
With a little help from PSM.
For added safet y, the system also read -
ies the brakes whenever a decreasing
distance to the vehicle in front is detect -
ed. 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 sys -
tem 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 enhances the
car’s driving dynamics and directional
stability when accelerating on inconsis
-
tent 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 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.

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.

no longer apply, which is recorded using
a camera.
Information is shown on the colour TFT
display in the instrument cluster and
via PCM. If the driver misses a traffic
sign – e.g. due to heav y rainfall or
darkness – the speed limit stored in
the navigation module is automatically
displayed.
This leaves the driver free to focus on
the road ahead.
Optional for all Cayenne models.
Speed limit indicator
Adaptive cruise control with
Porsche Active Safe (PAS).
Optional on all Cayenne models, adaptive
cruise control regulates the speed of your
vehicle in line with that of the ve hicle in
front. To do that, the system uses a radar
sensor in the central air intake to monitor
the road up to 200 m ahead.
If you approach another vehicle that is
travelling slower than your selected
cruising speed, the system slows the
engine or gently applies the brakes.

This continues until the distance that
you have preset is maintained. If heavier
braking is required, the driver has to

actively intervene. Your vehicle will
now follow the one in front at a reduced
speed.
If the other vehicle decelerates further,
adaptive cruise control will continue to
reduce your speed – even down to a halt.
When the road ahead is free once more,
the car automatically returns to your
selected cruising speed between 30 and
210 km/ h. To pull away after an auto -
matic stop, simply use the control lever
or depress the accelerator pedal.
If selected by the driver, the integrated
Stop & Go function automatically applies
the brakes and then drives off again in
congested traf fic.
For added safet y, the system also
features integrated Porsche Active Safe
(PAS). The system visually and audibly
alerts the driver in the event of a sudden
decrease in distance and briefly tugs
on the brakes. It can also intervene in
the braking process and apply increased
braking pressure through to all- out emer -
gency braking, if required.
Optional for all Cayenne models.
