brake PORSCHE CAYNNE 2010 1.G Information Manual

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.

The Porsche ‘S’ has long been
a mark of heightened sports per­
formance and abundant reserves
of power. On the Cayenne S, it
also stands for strength, agilit y
and efficiency.
At the heart of the car is a natur­
ally aspirated 4.8 ­litre V8 engine
featuring direct fuel injection
(DFI, p. 38), VarioCam Plus (p. 37)
and a t wo ­stage intake manifold.
This helps to keep fuel consump ­
tion and emissions low, while
ensuring maximum output. In
short: 294 kW (400 hp), maximum
torque of 500 Nm and a top
speed of 258 km/ h (160 mph).
The Cayenne S accelerates from
0 to 100 km/ h (62 mph) in as
lit tle as 5.9 seconds. Fuel con ­
sumption has been reduced by
up to 23 % and CO
2 emissions by
as much as 26 %.
1), 2) The weight
of the car has also been lowered
by 180 kg
1). Drive is transmit ted to the road
with smoothness and precision
by the eight
­speed Tiptronic S,
which is now standard equipment
and includes gearshif t controls
on the steering wheel. The result:
optimum use of the available
power reserves.
Of course, to apply exceptional
power like this ef fectively, it
needs to be harnessed and con ­
trolled. For example, by Porsche
Traction Management (PTM,
p. 44). On the new Cayenne S,
this active all ­wheel drive system
features an electronically variable,
map ­controlled multi ­plate clutch,
an automatic brake differential
(ABD, p. 44) and anti ­slip regu­
lation (ASR, p. 44). Working
in conjunction with advanced
Porsche Stabilit y Management
(PSM, p. 66), PTM ensures the
required torque split in every
driving scenario. On or of f road. During performance driving,

as well as on leisurely journeys
or when towing heav y loads.
The black slats on the air intakes
make them appear larger, and
the car wider. Other distinctive
features include the 18 ­inch
Cayenne S III wheels.

energy recovery during braking.
A special bat tery management
and cooling system maintains
a constant temperature and
pro
tects the bat ter y from over­
heating. It also monitors the
charge/discharge processes. As
a result, the life of the bat tery is
optimised and its suitabilit y for
everyday use ensured, while
offering a high capacit y: 1.7 kWh. Systems that are usually depen­
dent on the output provided by

the combustion engine, such as
climate control, power steering

Hybrid. As they do not rely on
output from the engine, these
functions remain active when the
car is running in electric mode or
when it is ‘coasting’ or gliding

In summary: despite its six ­
cylinder powerplant, the new
Cayenne S Hybrid offers per­

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.

sensors are used to measure a
range of values, including the
rotational speed of all four wheels,
the lateral and longitudinal
acceleration of the car, and
the current steering angle.
If, for example, the rear wheels
threaten to lose traction under
acceleration, a greater proportion
of drive torque is automatically
transmit ted to the front axle by a more positive engagement of
the multi
­plate clutch. In addition,
ASR minimises wheel spin. During
cornering, the required level of
engine torque is distributed to the
front wheels to ensure excellent
lateral stabilit y.
In conjunction with advanced
Porsche Stabilit y Management
(PSM, p. 66), PTM ensures the
perfect distribution of drive
torque for optimum traction in all road scenarios, whether on
long straights, through tight cor
­
ners or on surfaces with dif ferent
friction coef ficients. If one of the
wheels is about to lose traction,
PTM uses the ABD function to
apply the corresponding brake.
As a result, more drive is auto ­
matically transferred to the op­
posite wheel. If both wheels on
one axle are in danger of slipping,
ASR immediately intervenes and
modifies engine output to main ­tain drive. As well as enhancing
traction and active safet y,

increased tendency for the body
to sway. PASM prevents this from
happening, thereby improving
stabilit y and occupant comfort. PASM has three setup modes:
‘Comfort ’, ‘Normal’ and ‘Sport ’.
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

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.
