2011 PORSCHE CAYENNE towing

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.

consistently within a specific
temperature range. The engines
in the Cayenne models are
therefore designed for ef ficient
cooling.
In order to reduce the frictional
losses that occur during warm -up,
all Cayenne models feature com-
prehensive thermal management.
Using intelligent control, it
activates the dif ferent cooling
circuits individually and on de-
mand, thereby ensuring that the
optimum operating temperature
for the engine and transmission
is reached more quickly. This
minimises friction – and keeps
fuel consumption and CO
2 emis-
sions low.
The V8 engines have an enhanced
coolant management system
offering effective temperature
control throughout the engine.
While 20 % of coolant flows longi-
tudinally through the crankcase,
the remaining 80 % serves the
cylinder heads using the proven
cross-flow principle (from hot to
cold).
On all Cayenne models, the piston
heads are cooled using oil-spray
jets integrated within the main
lubrication system.
The entire cooling system is
designed for prolonged heav y-
dut y use, e.g. of f-road driving
or heav y towing and carrying
applications.Lubrication.
The V8 engines use dry-sump
lubrication to ensure a consistent
supply of oil in all load conditions,
especially in of f-road terrain.
The oil reservoir is located inside
the engine. This saves on space
and reduces weight.
Oil is circulated around the V8
engines using a demand- driven
pump. This has been designed
for the toughest driving scenarios
on and off road, including per-
formance driving and extreme
gradients. The V6 engines have a wet-sump
lubrication system.
Ensuring a
reliable supply of oil, no mat ter
how challenging the driving
conditions.
Direct fuel injection on the
diesel engine (common-rail
injection system).
On the Cayenne Diesel, direct
fuel injection comes courtesy of
a common -rail injection system.
The injection pressure is now up
to 2,000 bar, ensuring optimum
distribution of the air/fuel mixture
– for greater performance. The
piezoelectric injectors provide
flexible injection rate
adjustment,
using exactly metered quantities
of fuel, with multiple injections
for each power stroke to deliver
smooth combustion.
Cooling systems.
A high -performance engine can
only maintain its maximum
capabilit y over a long service life
if all components are operating
Direct fuel injection (DFI).
DFI injects fuel directly into the
combustion chamber at up to
120 bar with millisecond precision
using electromagnetic injectors.
The injector position and spray
geometry have been carefully
designed to improve output,
torque, fuel economy and emis-
sions. The swirling of the fuel as
it enters each chamber increases
the mixing of air and fuel, thereby
enhancing combustion. By form-
ing the air/fuel mixture directly
in the combustion chamber, DFI
contributes to engine cooling.
As a result, it was possible to in-
crease the compression ratio and
therefore power and efficiency.

Compression with precision.
Essential for getting right to the point.

Available on the Cayenne,
Cayenne Diesel, Cayenne S
and Cayenne Turbo, this function
readies the car for of f-road use
or reverts the set ting to normal
road driving.
In Of f-road Mode 1, for example,
the maps for all relevant
systems, e.g. ABS, are adapted
to provide optimum traction. In addition, High Level I is
selected on vehicles featuring air
suspension with PASM. If that ’s
not enough, the air suspension
can be raised further to High
Level II to increase the approach/
departure angle and wading depth.
Push the of f-road control forward
again on the Cayenne, Cayenne S
and Cayenne Turbo to activate
Off-road Mode 2 – for even great-
er traction on dif ficult terrain,
the multi-plate clutch can be fully
locked.
The electronically variable rear
differential on the optional
Porsche Torque Vectoring Plus
(PT V Plus) is integrated within
the all-wheel drive system. This
automatically ensures the opti-
mum distribution of drive torque on particularly uneven surfaces.
If one of the rear wheels begins
to slip, the rear dif ferential varies
the amount of torque transmit ted
through each drive shaf t, thereby
restoring traction. In Of f-road
Mode 3, the rear dif ferential can
be manually locked using the main
of f-road control. Then both rear
wheels receive the same amount
of torque, regardless of surface
conditions. The optional PDCC
(p. 53) enables greater wheel
articulation in all three modes,
improving traction still further.
For effective prevention of dam-
age to the underside of the car,
all Cayenne models can be
equipped with optional of f-road
underbody protection comprising
rock rails with integrated skid
plates, a reinforced engine-bay
guard, additional protection
for fuel tank and rear axle, and
a second towing lug.
Operating concept.
With the help of Porsche Traction
Management (PTM), the Cayenne
can cope with even the most
demanding of f-road scenarios.
Simply move the main of f-road
control on the centre console
forward or backward to select
one of up to three off-road
modes (depending on the model).
Steep ascents leading to snow-
covered mountain lodges, boggy

Porsche Active Suspension
Management (PASM).
PASM is an electronic damping
control system. It of fers con-
tinuous adjustment of individual
damping forces based on current
road conditions and driving st yle.
During performance driving or
heav y of f-road use, there is an
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
prevailing driving conditions,
enabling greater car control and
improving comfort and safet y.
Optional for the Cayenne,

high -mounted upper arms are
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
completely revised and adapted
for a more immediate response
and greater driving dynamics.
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 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.
