2010 PORSCHE CAYENNE ECU

Since the company was founded
in 1948, we have always gone

our own way. This is the hallmark
of our independent spirit. Only
thus can we continue to meet

our high performance standards.
And yours. For the new Cayenne S
Hybrid we chose a highly sophisti ­
cated technical concept, as we
felt that this would perfectly
embody the key principle of an
alternative drive: ef ficiency.
The new parallel full hybrid drive
(p. 28) on the new Cayenne S
Hybrid features a 3.0 ­litre V6

supercharged engine and an elec ­
tric machine (motor/generator)
that provides add itional power on
demand. It offers levels of accel ­
eration that are comparable with
a V8 unit, but with a reduction of
up to 22 % in both fuel consump ­
tion and CO
2 emissions.1), 2) The
engine delivers 245 kW (333 hp),
while the electric machine gener ­
ates 34 kW (47 hp). Working
in tandem, they produce a total
output of 279 kW (380 hp).
With a top speed of 242 km/ h
(150 mph), acceler ation from
0 to 100 km/ h (62 mph) takes
6.5 seconds. Maximum torque
is 580 Nm.
On the parallel full hybrid system,
the electric machine and a

decoupler are integrated directly
into the drivetrain bet ween the
combustion engine and the eight ­
speed Tiptronic S. The decoupler
ensures positive engagement with
the combustion engine, thereby
offering several benefits –
both for the driver and the
environment.
Under moderate acceleration, the
electric machine can power the
vehicle independently. In order to
drive quietly through residential
areas, for example. The generator
can also be used to recuperate
energy during braking, i.e. for
charging the bat tery.
In addition, the electric machine
can be used to boost perform ­
ance – for faster acceleration,
particularly when pulling away.
Other energy ­saving features
include the car’s abilit y to glide
along, even when the engine is
turned of f. The hybrid system
therefore also brings significant
advantages when not driving in
urban traffic, as the vehicle can
simply ‘coast’ along many stretches of road without any power at all.
Together with the auto start /stop
function, the parallel full hybrid
system offers exceptional levels
of performance and efficiency.
The ‘hybrid’ designation on each
front wing is a discreet reference
to the innovative drive concept
within.
Inside the car, the TFT colour
display in the instrument cluster
provides information on the
current energy flow. Further

driving data is displayed via the
optional Porsche Communication
Management (PCM).
But the greatest benefit of all:
the new Cayenne S Hybrid
is a Porsche. And it drives like
one too.
We continually swim against the tide.
So you can ‘coast’ home.

Cycle). The respective figures were not recorded on individual vehicles and do not constitute part of the of fer. This data is provided solely

high­mounted upper arms are now
in aluminium. This axle design
ensures accurate wheel location,
greater agilit y and minimal inter ­
ference 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 stabilit y. 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
suspension. 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 suspension 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 stabilit y and compensates
for sudden load transfer. In short:
it enables a more relaxed way
of driving. Examples of intelligent
light weight construction on the
rear axle include hollow drive
shafts.
Steering.
The steering system has been
completed revised and adapted
for a sportier driving st yle.
Around the straight ­ahead pos­
ition, in particular, the ratio is
now more direct. With the variable
steering ratio and special valve
set tings on the power ­steering
system, optimum manoeuvrabilit y
is ensured. The turning circle of
the new Cayenne models is just
11.9 metres.
The steering column itself
consists of multiple collapsing
sections linked by t wo 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.
Servotronic.
Servotronic 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 new Cayenne S
Hybrid. Optional for the new
Cayenne, new Cayenne Diesel,
new Cayenne S and new
Cayenne Turbo.

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.

Child seats.
With their unique design, Porsche
child seats comply with the
latest safet y standards. Available
from Porsche Tequipment, they
have been specially tested and
approved for use in Porsche
vehicles, offering comfort and safet y for all passengers up to
12 years of age. All fabrics are
breathable, kind to the skin and
easy to clean. The covers can

be removed and are washable.
For added safet y, the Porsche
Baby and Porsche Junior Seat
ISOFIX come with their own five
­point harness with central
adjustment of the seat ­belt length.
All of the new Cayenne models
have standard ISOFIX mounting
points on the front passenger’s
seat and outer rear seats.

screen, interior, ignition and trailer
(if fitted).
The immobiliser system works
by automatically communicating
with the vehicle key. If the key
is approved, the engine can be
started as normal.
Washer fluid is delivered via t wo
heated jets, ensuring uniform
coverage of the entire windscreen
area.
The rear wiper system is designed
for maximum visibilit y in all
conditions.

This preparation enables future
installation of a vehicle tracking
system obtainable from Porsche
Tequipment. The system can
be used to locate a stolen vehicle
in 25 EU countries as well as
Norway, Switzerland and Russia –
irrespective of where you live. The vehicle is not tracked con­
tinually, only when the alarm is
triggered. In the event of vehicle
thef t or manipulation, or if the
loss of the vehicle is reported by
the owner, a silent alarm is auto
