2011 PORSCHE CAYENNE brake

At Porsche, we are continually
changing. Looking for a new and
dif ferent approach. Without ever
losing sight of where we’ve come
from. That ’s how we remain true
to ourselves.
The basic Cayenne concept is
therefore the same. We’ve just
continued to improve it: the
Cayenne is
now lighter – up to
165 kg
1) depending on the speci-
fication
– 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 econ-
omy. In other words: we have
enhanced the performance, while
significantly lowering the weight,
fuel consumption and CO
2 emis-
sions. 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
consumption 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
enables 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.
In addition to the standard
18-inch Cayenne wheels and
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.
So, a unique blend of the great
sports performance and unre-
stricted everyday practicalit y that
is t ypical of 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 standard eight-speed
Tiptronic S, which includes gear-
shif 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 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 d-
ent on the output provided by
the combustion engine, such as
climate control, power steering
and brake assist , run solely
on electricit y on the Cayenne S
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
along with the engine turned of f.
In summary: despite its six-
cylinder powerplant, the
Cayenne S Hybrid offers per-
formance levels that are com-
parable with an eight-cylinder
unit – but with significantly lower
fuel consumption.
Also when it comes to hybrid
drives, we’ve taken a completely
new path. Hardly surprising really,
with a technology this convincing.
The compact bat tery is located
under the loadspace floor in the
luggage compartment. Weighing
80 kg, its dimensions are
426 mm x 925 mm x 286 mm.
The bat tery is designed to last
without the need for any main-
tenance. As the electric machine
also functions as a generator,
it can charge the bat tery under
certain conditions when
the combustion engine is in
The hybrid system features a
high -voltage nickel metal hydride
(NiMH) bat tery consisting of
240 cells. It provides the electric
machine with the energy required
for the vehicle to drive short
distances solely on electric
power.

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.
Overall, the system provides
greater performance with rela-
tively modest fuel consumption.
Standard on the Cayenne S
and 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 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.

The 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 maintain drive. As well as en-
hancing traction and active safety,
