2010 PORSCHE CAYENNE four wheel drive

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.

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 %.

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

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,

Ty r e s .
All t yres have been optimised
with regard to driving perform­
ance, handling, rolling resistance
and weight. They also provide
great potential for reducing fuel
consumption and emissions. The three basic components of
the t yre have been enhanced –
the rubber compound, tread de­
sign and the architecture of the
substructure. This reduces rolling
resistance and fuel consumption.
Tyre Pressure Monitoring
(TPM).
Tyre Pressure Monitoring (TPM)
provides early warning of any
drop in pressure via the on
­board
computer display. In addition, the driver can quickly
and easily check the individual
pressures in all four wheels via
the multi
­purpose display in the
instrument cluster. Standard on the new Cayenne
Turbo. Optional for all other
new Cayenne models.

All Cayenne models have internal­
ly vented discs all round, ensuring
consistent performance during
heav y use. The front disc dimen ­
sions (diameter/thickness) are
350 mm/34 mm on the new

Cayenne and new Cayenne Diesel,
360 mm/36 mm on the new
Cayenne S and new Cayenne S
Hybrid, and 390 mm/38 mm on
the new Cayenne Turbo. All models have six
­piston
monobloc aluminium brake
calipers at the front and four ­
piston equivalents at the rear.
The calipers are black on the new
Cayenne and new Cayenne Diesel
and silver on the new Cayenne S
and new Cayenne S Hybrid. On
the new Cayenne Turbo, they
feature a striking red paint finish. Braking is assisted by a tandem
booster and large brake master
cylinder. Further assistance is
provided by PSM (p. 66).
The pads are equipped with
individual wear sensors. When
new pads are required, a
warning light is illuminated in
the instrument cluster.
Electric parking brake.
Manually activated and deactivat ­
ed, the electric parking brake
releases automatically as you drive
off.
Automatic hold function.
With the automatic hold function,
you can pull away on the flat or a
slope without ever rolling back.
The system automatically detects
when the vehicle has come to a
halt on an uphill gradient. PSM then
maintains the brake pressure at all
four wheels for a brief period to
prevent the vehicle from moving in
the opposite direction.
Braking systems.
Porsche brakes are renowned
worldwide as the benchmark in
performance
and durabilit y.
Equipped with new braking
systems, the new Cayenne
models continue this tradition.
The larger brakes of fer excellent
deceleration – even when the
car is fully laden with five adult
occupants, a full complement
of luggage and a braked trailer
load of up to 3,500 kg (Cayenne
with manual gearbox: 2,700 kg).
Outstanding brake performance.

PSM has three additional func­
tions that help reduce braking
distances. If the throt tle pedal
is released suddenly, PSM

automatically readies the braking
system. The pressure in the
brake lines is marginally increased,
bringing each of the pads into
light contact with the correspond ­
ing disc. If the driver goes on
to apply the brakes, the calipers
respond more quickly and the
braking distance is reduced. In an emergency stop – i.e. when
the pressure on the brake pedal
exceeds a certain threshold –
the brake assist function uses the
PSM hydraulics to apply maximum
braking force at all four wheels.
For added safet y, the system
also readies the brakes whenever
a decreasing distance to the
vehicle in front is detected. The
optional adaptive cruise control
and PSM interact to prefill the
brakes.
Even if adaptive cruise control is
inactive, the system registers the
speed of the vehicle in front and
automatically readies the braking
system. In addition, the system
alerts the driver to the decreasing distance by briefly tugging on
the brakes.
PSM also features a trailer
stabilisation function – for a
significant contribution to car
and trailer safet y.
Within the laws of physics, it
compensates for load transfer
caused by throt tle and brake

inputs up to the maximum degree
of lateral acceleration. It also en ­
hances the car’s driving dynamics
and directional stabilit y when
accelerating on inconsistent road
surfaces.
Other features include a special
control strategy in the ABS
for braking on loose surfaces.
By briefly locking the wheels, a wedge is formed ahead of each
t yre which provides additional
purchase to help slow the car,
e.g. on gravel or snow.
For a more involving driving

experience, PSM can also be
disabled, but remains active in
the background.
Standard on all new Cayenne
models.

ration of the car. Using
this information, it is possible to
calculate the actual direction of
travel at any given moment. If
the car begins to oversteer or
understeer, PSM applies selective
braking on individual wheels to
restore stabilit y. If necessar y,
PSM can also intervene in the
engine management system to
temporarily modif y the amount of
drive transmit ted to the wheels.
