light PORSCHE CAYNNE 2010 1.G Information Manual

At this point, it would be very
tempting for us to wax lyrical
about our new models. How­
ever, we prefer to devote our
time to the essentials – our
customers’ requirements. The
brief was clear: a lighter, more
efficient and more dynamic
vehicle offering greater safet y
and enhanced comfort. In short:
more Porsche than ever before.
The new Cayenne. To the point.

Tiptronic S (p. 42)
, while

As always, we’ve focused on
what ’s really important. To the
point: the new Cayenne models.
Tiptronic
S (p. 42) and VarioCam
Plus (p. 37). The interaction
bet ween all components has
also been optimised.
Another of our principles: high
performance should never come
at the expense of comfort or
safet y, and this is something we
have kept to. Even with a car
offering the phenomenal output
of the new Cayenne Turbo. Its
4.8 ­litre V8 powerplant develops
500 hp, which is guaranteed to
set pulse rates climbing and
send a shiver down the spine –
both natural reactions in a
turbocharged Porsche. Standard
active safet y features include
Bi ­Xenon headlights with the
Porsche Dynamic Light System
Sometimes that means us

venturing of f in unusual directions
– as with the first Cayenne to be
fit ted with a diesel engine, for
example. However, it has become
clear that even with a new drive
system, the Cayenne can continue
to remain true to the trusted
Porsche principle.
The new Cayenne and new

Cayenne S are now more powerful
and ef ficient, while also delivering
exceptional capabilit y of f road.
The result: greater driving pleasure
with reduced fuel consumption
and CO2 emissions. On and off road.
This has also been achieved
through the use of advanced
technologies such as direct fuel
injection (DFI, p. 38), eight ­speed
As usual, the critics were ready to
have their say, as with every new
product we create. Can it still be
considered a Porsche? Why have
they done that? The questions

are always the same. As is our
answer: we do what we feel
is in the best interest of our
customers.
(p. 36). For increased comfort
and safet y, Lane Change Assist
(LCA, p. 105) and adaptive

cruise control (p. 104) are

available as an option. Ensuring
a phenomenal sound experience
in every seat position is the
optional Burmester
® High ­End
Surround Sound System (p. 94).
One thing is for sure: the new
Cayenne models are guaranteed
to surprise.
The most innovative – and there ­
fore in keeping with the rest of
the Porsche family – is the new
Cayenne S Hybrid. Its parallel full
hybrid system (p. 28) harnesses
the power of an electric machine
(motor/generator) and an internal
combustion engine. This provides
several clear benefits for the
driver: outstanding sportscar
performance combined with
excellent fuel economy.
Once again, t ypically Porsche.
Versatilit y combined with
superlative performance and
exceptional handling. These are
character traits shared by the
entire Cayenne model range. We
have simply honed and refined
them. For each individual model.
And we have also extended the
range of drives. The Cayenne
now comes in a wider choice of
variants, each one more dynamic,
practical and comfortable than
ever before. And also more
ef ficient. Fuel consumption has
been reduced by up to 23 %
and CO
2 emissions by up to
26 % (depending on the model).
This was achieved thanks to
the Cayenne models being

considerably lighter, with each
one weighing up to 185 kg less
than the respective previous
model. They also feature a host
of advanced technologies such
as the auto start /stop function
Those who develop talent reap the reward.
Sometimes in more ways than one.
The Cayenne models.
12 · The new Cayenne | Model range

When we launched the first
Cayenne in 2002, it was met with
great scepticism. Can it still be
considered a Porsche at all? Our
reply: never before in the history
of the company, has a model
gone from 0 to 100,000 sold
units so quickly. And even more
importantly, the Cayenne has
conquered the SUV market by
demonstrating that exceptional
sportscar performance is not
just restricted to the road.
The basic concept is therefore
the same. We’ve just continued to
improve it: the new Cayenne is
now lighter – up to 165 kg1) depend­
ing
on the specification – and also
more dynamic, more comfortable,
and closer to the road than ever
before. Without detracting from
the
qualities required for off ­road
driving or towing heav y loads.
Its naturally aspirated 3.6 ­litre
V6 engine features direct fuel
injection (DFI, p. 38), variable
valve timing on both inlet and
exhaust, and a variable resonance
intake manifold – for a generous
output and excellent fuel
economy. In other words: we have enhanced the performance,
while significantly lowering the
weight, fuel consumption and CO
2
emissions. The figures speak for
themselves: maximum torque of
400 Nm, 220 kW (300 hp), a top
speed of 230 km/ h (143 mph)
and the abilit y to accelerate from
0 to 100 km/ h (62 mph) in
7.5 se conds. With both fuel con­
sumption and CO
2 emissions

reduced by 20 %.
1), 2) Delivering
this power to the road efficiently,
Porsche Traction Management
(PTM, p. 44) combines active all ­
wheel drive
with an electron ically
variable

multi ­plate clutch, auto ­
matic brake dif ferential (ABD) and
anti ­slip regulation (ASR). PTM
ensures the perfect distribution of
drive torque to all four wheels,
whether on long straights, through
tight corners or on surfaces with
dif ferent friction coef ficients: for
dynamic handling
and increased
traction. Drive is transmit ted
through a high ­performance

six ­speed manual gearbox (p. 42),
which ensures optimum progres ­
sion through the gears. The gear
lever throw is short and precise,
with only minimal driver ef fort
required. In addition to the standard
18
­inch Cayenne wheels and
new larger brakes, the Cayenne
can be fit ted with the optional
Porsche Ceramic Composite
Brake (PCCB, p. 64) – for out ­
standing brake performance.
Another key advantage: a total
weight saving of approximately
50 % compared with equivalent
cast ­iron discs.
The generous standard equipment
includes partial ­leather seats,
climate control, the CDR ­31 audio
system with touchscreen, cruise
control and automatic headlight
activation. For added comfort,
there’s also a ‘Welcome Home’
lighting function. When you arrive
at a destination af ter dark, the
headlights remain illuminated for
a user ­defined period, lighting
your path from the car.
In terms of enhancing the
agility
and practicalit y of the
new
Cayenne, the goal we set

ourselves was very clear: even
more Porsche. Let ’s be honest,
would you have expected any ­
thing else?
Everything has changed. Apart from the concept.

Turbo is equipped as standard
with air suspension
featuring self­
levelling and ride ­height control,
as well as Porsche Active Suspen ­
sion Management
(PASM, p. 51).
This electronic damping control
system offers continuous adjust ­
ment of the damping forces
on each wheel – depending on
current road conditions and

the new Cayenne Turbo include
Bi
­Xenon headlights with Porsche
Dynamic Light System (PDLS,
p. 61), larger air intakes and a
distinctive ‘power dome’ on the
engine lid – a clear reference to
the enormous potential within.
Based on the same solid
foun
dations as its predecessor,
the new Cayenne Turbo blends
phenomenal performance with
comfort and ef ficiency. It does
so in st yle but without ever
compromising on any one in
particular. Because we believe
that less can also mean more.
Reduced weight, lower fuel consumption, fewer emissions.
At Porsche, we believe less is more.

Standard on the new Cayenne
Diesel, new Cayenne S, new
Cayenne S Hybrid and new

Cayenne Turbo. Available as an
option for the new Cayenne
in conjunction with the optional
Tiptronic S.
VarioCam Plus.
VarioCam Plus creates t wo en ­
gines out of one by steplessly
adjusting the inlet valve timing
and lift.
The system dif ferentiates
bet ween normal road usage and
performance driving, adapting
seamlessly as driver inputs
change. All functions are auto ­
matically controlled by the

engine management system.
All you experience is responsive
acceleration and ultra ­smooth
running characteristics. Inlet valve
timing is steplessly adjusted. To
improve response when starting
from cold, for example, VarioCam
Plus selects the higher lif t set ting
and retards valve timing.
At medium revs and minimal
load, the valve lif t is lowered and
timing advanced to minimise fuel
consumption and emissions. At
low engine speeds in particular,
VarioCam Plus significantly im ­
proves fuel economy. To achieve maximum power and torque, the
valve lif t is raised and the timing
advanced.
Overall, the system provides
greater performance with rela­
tively modest fuel consumption.
Standard on the new Cayenne S
and new Cayenne Turbo.
Variable valve timing.
The V6 engine in the Cayenne
features variable valve timing
on both inlet and exhaust. The camshaft phase angles

are continuously varied by

the engine management system
via rotary ­vane adjusters.
On the new Cayenne S Hybrid, the
inlet valve timing is continuously
adjusted.
The key benefits include bet ter
fuel economy and lower emis ­
sions. It also helps to generate
greater power and torque –
even at low engine speeds.
Standard on the new Cayenne
and new Cayenne S Hybrid.
The starter motor has been re
­
vised to cope with the additional
demands of the system, and
the bat tery charge and life are
continuously monitored. The
bat tery and starter motor are
replacement parts that are
subject to greater wear and
tear with frequent use of the
auto start /stop function.

systems remain switched on and
the standard climate control

continues to maintain the selected
temperature. The only changes
you’ll perceive: peace and quiet
and – thanks to greater fuel
economy – also peace of mind.
The system is deactivated in
certain situations, e.g. if the
outside temperature is very

high or the bat tery charge is low.
Auto start/stop function.
The new Cayenne models that
are equipped with the new eight ­
speed Tiptronic S also feature an
auto start /stop function. If, for
example, you stop at traf fic lights
with your foot on the brake pedal,
the auto start /stop function will
automatically cut the engine.

response, even at low revs and
road speeds. This is particularly
useful when driving in urban
traf fic. The supercharger has a
low­temperature water cooling
system for cooling the charge air.
Variable Turbine Geometry in
the new Cayenne Diesel.
The turbocharger in the new
Cayenne Diesel features Variable
Turbine Geometry (V TG). The
gas ­flow from the engine is
channelled onto the turbines via
electronically adjustable guide
vanes. By changing the vane
angle, the system can replicate
the geometry in all t ypes of
turbo, large or small, and thus
achieve the optimum gas ­flow characteristics. As a result, even
at low engine rpm, the turbine
speed is maximised. For a sig
­
nificant increase in boost pres ­
sure, excellent cylinder charging
plus greater power and torque.
Electronic engine management.
Cultured performance in all
driving scenarios requires com ­
prehensive engine control. The
electronic engine management
system does this by continually
monitoring the relevant input data
from a variet y of sophisticated
sensors. This data is then com ­
pared with a corresponding set of
reference values. Based on this
information, a range of key engine
functions, e.g. ignition and in­
jection timings as well as injection
quantities, are seamlessly and
automatically adjusted. Other
major functions include automatic
compensation for changes in fuel
qualit y and control of the variable ­
tract intake manifold. On the
new Cayenne Turbo, the engine management system also regu ­
lates the turbo boost pressure.
The results:
optimum fuel eco
n ­
omy and lower CO
2 emissions as
well as greater power and torque
at all times.
Exhaust system.
The light weight exhaust systems
in the new Cayenne models are
made from special, long ­life stain ­
less steel. The key features of
the catalysts are high ef ficiency,
faster warm ­up and a long service
life. The sports exhaust system
1)
available as an option on the
new Cayenne and new Cayenne S
provides an even more distinctive
sound. The package also includes
a specially designed set of t win
dual ­tube tailpipes. All exhaust
systems, standard and sports,
comply with the strict EU5 emis ­
sions legislation.
2)
Turbocharging system in the
new Cayenne Turbo.
In the new Cayenne Turbo, the
engine is assisted by t win turbo ­
charger units arranged in parallel
– one for each bank of cylinders.
Incoming air is passed through
a filter and compressed by the
turbine units. Its temperature is
then reduced in the t win inter­
cooler system, which improves
cylinder charging and limits
thermal loads on the engine.
Supercharging system in the
new Cayenne S Hybrid.
The engine in the new Cayenne S
Hybrid is equipped with a
supercharger. For a more direct
Air intake system.
The Cayenne models are all
equipped with a resonance air
intake system. This technology
uses the pressure waves
generated by the inlet valves
to ‘force’ air into the engine.
The ef fect is enhanced in the new
Cayenne and new Cayenne S by
a t wo ­stage intake manifold. This
variable geometry combines all
the benefits of a long intake tube
(higher torque at low rpm) with
those of a shorter length (more
power at higher rpm).
The result: highly impressive
torque ratings across the entire
engine speed range.

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.

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.
