2010 PORSCHE CAYENNE steering

Boasting outstanding perform­
ance and ef ficiency, the new
Cayenne Diesel is ideal for longer
journeys – offering high levels
of torque, while fuel consumption
remains low.
Its 3.0 ­litre V6 turbo ­diesel engine
is powerful and refined. The unit
generates 176 kW (240 hp) and
maximum torque of 550 Nm.
The sprint to 100 km/ h (62 mph)
requires just 7.8 seconds. Top
speed is 218 km/ h (135 mph).
In addition, both fuel consumption
and CO
2 emissions have been
reduced by up to 20 %.
1), 2)
Direct fuel injection comes
courtesy of a common ­rail

injection system. The injection
pressure of up to 1,800 bar en ­sures optimum distribution of the
air/fuel mixture – for enhanced
dynamics. The piezoelectric
injection valves enable multiple
injections for each power stroke
to deliver efficient combustion.
The turbocharger on the new
Cayenne Diesel features Variable
Turbine Geometry (V TG, p. 40),
generating a higher output and
impressive torque, even at low
engine speeds.
Now standard equipment, the
new eight
­speed Tiptronic S
includes gearshift 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 acceleration. 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 enhances
the range to well over 1,000 km
(approx. 620 miles) while keeping
the engine rpm and noise levels
l o w.
The new 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 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.

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

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

the car to the road are the new
19 ­inch Cayenne Turbo wheels. The chassis on the new Cayenne
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

driving st yle.
This enables greater
car control, improving safet y and
comfort.
Comfort is also key in the new
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 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.

A special bat tery management

a result, the life of the bat tery is
optimised and its suitabilit y for
everyday use ensured, while

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

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,

During performance driving or

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 new Cayenne,

At slow and medium speeds, PT V
