2010 PORSCHE CAYENNE light

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.
To the point.

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.

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,

curtain­t ype airbags on each
side of the roof offering opti ­
mum head protection for both
rows of seats and side impact
protection elements in each
door. Side airbags at the rear
are also available as an option.
Two impact sensors are located
at the front of the car to enable
bet ter detection of a head­on
collision. The driver and front
passenger airbags use a gas
generant based on an organic
propellant. As a result, the air ­
bags are lighter, more compact
and easier to recycle. A roll ­over
detection system provides
additional protection in the event
that the car were to overturn.
Using sensor ­acquired data, it
enables early deployment of
the curtain airbags and triggers
the seat ­belt pre ­tensioners.
Seat belt system.
The Cayenne models feature
three ­point seat belts on all
five seats, as well as seat ­belt
pre ­tensioners (front and outer
rear seats) and force limiters
(front seats only).
ISOFIX mounting points.
The front passenger seat and
outer rear seats are equipped
with ISOFIX mounting points for
compatible child seats (p. 84)
as standard. If a child seat is
mounted on the front passenger
seat, the corresponding airbag
can be quickly deactivated using
a key ­operated switch.
Airbags.
All Cayenne models are equipped
with full ­size front airbags for
driver and front passenger as
standard. These are augmented
by Porsche Side Impact Protec ­
tion (POSIP). This comprises
a side airbag in each front seat,
Bodyshell construction.
Our ongoing development of
the light weight steel body is a
decisive factor in the enhanced
passive safet y and unparalleled
rigidit y of the Cayenne body.
In the event of an accident, a
system of side and cross ­

members at the front of the car
helps to channel impact energy
in a safe and predetermined
manner. The interior is protected
by hot ­formed super high ­strength
steel reinforcements, including
side intrusion beams in each of
the doors.
High strength and consistent

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 locat ­
ed in Weissach where it shares
premises with the Automotive Industry Exhaust Emission Centre
(ADA).
Just a coincidence? We call
it symbiosis.
In practice: the new Cayenne is
up to 185 kg lighter, depending
on the model.
1) This was achieved
through new weight ­saving devel ­
opments and materials, new pro ­
duction technologies, advanced
functionalities and concept
modifications. By using lighter materials, for example, we have
halved the weight of the tailgate.
New materials are also a feature
of the axle construction, with
steel being replaced where pos­
sible by light weight alter
natives
such as aluminium and plastic.
The benefits for the driver:
greater agilit y and driving
dynamics – with lower fuel
consumption. Ef ficiency at
its best.
This is achieved using advanced
engine concepts featuring tech ­
nologies such as DFI (p. 38),
VarioCam Plus (p. 37), the auto
start /stop function (p. 36), the
parallel full hybrid drive and con ­
sistent light weight construction.The concept behind every car we
build is based around the pursuit
of performance. 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 bet ween
the t wo.
Great achievements are something to be proud of.
Even more so if they benefit the world around you.
Environment.
1) Compared to previous model.

Thanks to single­spark 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 require ­
ments mean less waste disposal
and fewer demands on natural
resources. They also lower the
cost of ownership while keeping
your car on the road. The new Cayenne S Hybrid
doesn’t require any additional
servicing.
Service intervals for the Cayenne
models are dependent on a range
of factors, including local fuel
qualit y. 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: sustainabilit y.
The light weight exhaust on the
Cayenne models, for example,

is constructed from long ­life
stainless steel.
Every Porsche model is entirely
free of asbestos, CFCs and
components manufactured using
CFCs. All legal requirements in
respect of recycling are fulfilled.
Materials are clearly labelled for subsequent identification and
sorting to facilitate ef ficient
recycling.
While more than 95
% of the car
can be recycled using current
technologies, the chances are
your new 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
t o day.

environmental issues, please

Servicing.
With lengthy service intervals
and long ­life components, vehicle
maintenance is kept to a min­
imum. 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.
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’ bet ween com ­
ponents, 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 of ficial t yre partners. Wind
noise levels have also been
lowered thanks to aerodynamic
refinements.
All that remains is a sound that is
pure Porsche.
