2011 PORSCHE CAYENNE power steering

Boasting outstanding perform-
ance and ef ficiency, the Cayenne
Diesel is ideal for longer journeys
– of fering high levels of torque,
while fuel consumption remains
l o w.
Its new 3.0 -litre V6 turbo - diesel
engine is now more powerful and
refined, and approximately 20 kg
l i g h t e r.
1) The unit generates
180 kW (245 hp) and maximum
torque of 550 Nm. The sprint
to 100 km/ h (62 mph) requires
just 7.6 seconds. Top speed
is 220 km/ h (137 mph). Fuel
con sumption now comes in at
just 7.2 l/100 km (39.2 mpg) in
the EU cycle.
2)
Direct fuel injection comes cour-
tesy of a common-rail injection
system. The piezoelectric
injectors now enable multiple
injections at a pressure of up to 2,000 bar, ensuring optimum
distribution of the air/fuel mixture
– for improved dynamics.
The new turbocharger on the
Cayenne Diesel features Variable
Turbine Geometry (V TG, p. 40).
Combined with optimised channel-
ling of the intake air, it enhances
the charging ef fect, thereby
generating a higher output and
impressive torque, even at low
engine speeds.
The standard eight-speed
Tiptronic S includes gearshif t
controls on the steering wheel.
Transmit ting the high torque
of the Cayenne Diesel smoothly
and ef fectively, the eight gears
are designed to facilitate both
economical driving
with low fuel
consumption and
performance
driving with em phatic accele ration.
Porsche Traction Management
(PTM) permanent all-wheel
drive with self-locking centre
dif ferential transmits the car’s
power to all four wheels with
optimum precision and control.
Available as a no - cost option,
the 100 -litre fuel tank increases
the range to well over 1,000 km
(approx. 620 miles) while keeping
the engine rpm and noise levels
l o w.
The Cayenne Diesel: proof that
a 100 -metre sprinter can also run
a marathon. The only thing running low on long journeys:
fuel consumption.

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.

Understatement coupled with
clear statements: lower fuel
consumption, faster acceleration.
Supreme engineering that speaks
for itself. In short, every thing
you’d expect from a Turbo.
Another clear statement is the
distinctive sound from the t win
dual-tube tailpipes. Produced by
the 4.8-litre t win -turbo V8 engine
that delivers 368 kW (500 hp)
and features direct fuel injection
(DFI, p. 38). The car has a top
speed of 278 km/ h (173 mph)
and the benchmark sprint from
0 to 100 km/ h (62 mph) is com-
pleted in 4.7 seconds. Maximum
torque is 700 Nm. Here too, fuel
consumption has been reduced
by
23 % and CO2 emissions by
2 5 % .

Optimum traction and safet y are
provided by Porsche Traction
Management (PTM, p. 44) active
all-wheel drive. Also connecting
the car to the road are the 19 -inch Cayenne Turbo wheels.
The chassis on the Cayenne Turbo
is equipped as standard with air
suspension featuring self-levelling
and ride-height control, as well
as Porsche Active Suspension
Management
(PASM, p. 51). This
electronic damping control sys-
tem offers continuous adjustment
of the damping forces
on each
wheel – depending on
current
road conditions and driving st yle.
This enables greater car control,
improving safet y and comfort.
Comfort is also key in the
Cayenne Turbo interior. Standard
equipment comprises an interior
package in smooth-finish leather,
a rooflining in Alcantara and an
electrically adjustable steering
column.
Also fit ted as standard: the
BOSE® Surround Sound System,
Porsche Communication
Management (PCM) with navi-
gation module, adaptive sports
seats with comfort memor y package (18-way), Tyre Pressure
Monitoring (TPM, p. 57), auto -
matic headlight activation and
automatically dimming exterior
and interior mirrors.
Exterior features exclusive to
the Cayenne Turbo include
Bi-Xenon main 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.
Following our long established
principles,
the Cayenne Turbo
blends phenomenal performance
with outstanding comfort and
efficiency. 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.

part-throt tle mode and through
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.

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.
Standard on the Cayenne S
Hybrid. Optional for all other
Cayenne models.
Front axle.
The chassis on the Cayenne
models offers a direct response –
for a more rewarding driving
experience.
The wishbones on the subf rame-
mounted front suspension with
Weight reduction.
The axle concept on the Cayenne
models features con sistent light-
weight construction. The results:
enhanced driving dynamics, lower
fuel consumption and optimum
occupant comfort.
Shedding weight.
Adding agility, economy and comfort.
