Performance. It’s what motivates
our engineers – and exhilarates
our drivers. Winning races,
exploring new terrain, achieving
new objectives.
With the Cayenne model range,
we’ve applied this power to an
ambitious range of applications.
The result is four highly
versatile cars – every
one of them a Porsche.
At Porsche, we believe in playing to our strength:
the pursuit of excellence in every respect.
The Cayenne models.
The Cayenne models
One thing they have in common
is the standards they set: in
performance, safety and economy.
The character of each car is
apparent at first glance: accom-
plished, athletic, brimming with
energy and potential. The front
and rear sections are elegantly
designed with excellent aerodynamic
properties. The flared wheel arches
accommodate a range of wheel
options up to 21 inches in diameter.
Among the most distinctive features
on all four models is the elongated
headlight geometry. In addition,
each car has LED taillights as
standard (see page 93).
The stylish form is brought
thrillingly to life with remarkable
engine performance. The high-
capacity engines offer increased
power and torque with relatively
modest fuel consumption. This is
achieved using a range of technol-
ogies
, including direct fuel injection
(DFI – see page 50) and VarioCam
Plus on the V8 engines (see page
53).
The sports-oriented suspension can
be further refined with the optional
Porsche Dynamic Chassis Control
(PDCC – see page 80), an active
anti-roll stability system. Safety is an equally important consideration,
with Porsche Stability Management
(PSM – see page 98) included
as standard equipment. The race-
proven Porsche Ceramic Composite
Brake (PCCB– see page 96) is
also available as optional equipment.
The Cayenne models.
Ready for every eventuality.

models have a flattened headlight
geometry which gives a broader
look to the car.
The air intake openings are designed
for optimum cooling. On the
Cayenne GTS and Cayenne Turbo,
the central air intake has a larger
cross-sectional area to compensate
for the higher engine outputs. In the
outer intake openings are a pair of
Dynamism and power – both
immediately apparent in every
Cayenne model.
The front-end design on the
naturally aspirated models features
H7 projector-beam headlights.
The Cayenne Turbo has Bi-Xenon
headlights with static and dynamic
cornering lights (also optional on
the other three models). All four
elongated light units containing the
turn-signal indicators and sidelights.
These are positioned vertically on
the Cayenne and Cayenne S, and
horizontally on the Cayenne GTS
and Cayenne Turbo. Another
distinguishing feature on the
Cayenne Turbo is the ‘power-domed’
engine lid.
The rear section also alludes to
the powerful capability of each car.
Integrated within the rear apron
are a pair of single-tube tailpipes
on the Cayenne and Cayenne S,
and dual-tube tailpipes on the
Cayenne GTS and Cayenne Turbo.
The tailpipes on the Cayenne GTS
have a chrome-plated finish. All
four models have a diffuser-style
design on the lower rear apron
plus LED taillights and brake
lights. An extended bi-plane roof
spoiler is available as a no-cost
option on the Cayenne GTS.
The interior space is designed
around the driver in a range of
quality materials. Full leather
upholstery is standard equipment
on the Cayenne GTS and Cayenne
Turbo. Also included as standard
on the Cayenne GTS is a new
sports seat design featuring
greater lateral support and a
comfort memory package (sports
seats optional on all other models).
In short: a powerful first
impression, inside and out, that
is also enduringly Porsche.

Another impressive feature is the
new braking system. The larger-
diameter discs provide extremely
high standards of active safety
in all driving scenarios. As a result,
the Cayenne Turbo achieves bench-
mark performance in decelerationand stability under load. The new
calipers are larger in size with
a distinctive red paint finish. The
Porsche Ceramic Composite
Brake (PCCB) is available as an
option.
Externally, the Cayenne Turbo is
instantly recognisable by the
‘power domes’ on the engine lid.
Other standard features include
Bi-Xenon headlights with static and
dynamic cornering lights. Together
with the elongated lights in the
front air intakes, they lend additional
presence and character to the car.
The interior is a blend of sporting
style and exclusivity: comfort
seats with a comfort memory
package and leather upholstery
as standard. Sports seats are
offered as a no-cost option, also
with a comfort memory package.
The standard BOSE®Surround
Sound System delivers perfect
sound at every seat position.
Other standard features include
Porsche Communication
Management (PCM) with satellite
navigation (see page 132).
The cluster of five round instru-
ments in the Cayenne Turbo has
a 5-inch colour display in the
central dial. This provides infor-
mation from a range of systems,
including the on-board computer.
The far right-hand dial contains
the boost pressure gauge.
All interior trim elements in the
Cayenne Turbo have an elegant
satin aluminium finish.

Power is the product of efficiency.
Lightweight alloy engine construction.
‘Less is more’ – less weight, more
performance – is a key principle of
Porsche design.
The V8 Cayenne engines have
a ‘closed-deck’ aluminium
crankcase and lightweight
aluminium bedplate. The cylinder
block and its associated coolant
channels are therefore a fully
enclosed system. This not only
reduces the weight of the engine,
it also improves its dimensional
stability. Since the engine is
stronger, it also has a longer
service life.
Other major lightweight compon-
ents include cast aluminium
pistons and aluminium cylinder
heads. On the Cayenne Turbo, the
pistons are forged to compensate
for the higher loads.
The Cayenne V6 has a cast-iron
crankcase and one-piece cylinderheads in die-cast aluminium. This
combination produces high power
output while reducing the weight
of the engine.
Drive
Lightweight construction used on the V8 engines
Consistent performance and a longer service life.
Engine cooling system.
Each engine remains within its
optimum temperature range at
all times. Clearances throughout
the engine are extremely small,
thereby reducing wear. The entire
cooling system is designed for
prolonged
heavy-duty use, e.g.,
off-road driving or heavy towing
and carrying applications.
Emissions, noise and fuel
consumption remain low, while
power and torque are improved.
Lubrication.
The V8 engines use dry-sump
lubrication to ensure a consistent
supply of oil in all load conditions.
The oil reservoir is located inside
the engine. As well as saving
space and reducing weight, the oil
is always there where it’s needed.
Oil is circulated around the
V8 engines using a demand-driven
pump and two-stage scavenging
system, providing optimum
delivery in even the toughest
scenarios.
The V6 engine has a wet-sump
lubrication system that is
also designed for challenging
conditions, e.g., performance
road driving or extreme off-road
gradients.
A high-performance engine can
only maintain its optimum capability
over a long service life if all com-
ponents are operating consistently
within a specific temperature
range.
The V8 engines have an optimised
coolant management system offering
effective temperature control
throughout the engine. While 20 %
of coolant flows longitudinally
through the crankcase, 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 in the main lubrica-
tion system.

The smallest things can make the biggest difference.
Even a single spark.
Ignition system.
The Cayenne models have a
static high-voltage ignition
system with separate ignition
coils on each individual plug.
As well as providing a more consistent spark, this is a
more reliable alternative to
a conventional distributor and
leads. The role of distributor
is performed by the engine
management system. As well
as improving performance
and economy, emissions are
prevented at source.

the Cayenne S (in conjunction
with Tiptronic S), it has a
performance sound setting
which is automatically enabled in
‘Sport’ mode. The package also
includes twin dual-tube tailpipes
with chrome-plated finish. (Note:
vehicles equipped with the sports
exhaust system have a reduced
off-road capability.)
All exhaust systems – standard
and sports – comply with all
relevant emissions legislation.
Longer service intervals are
not only more convenient and
financially attractive, they are
also better for the environment.
Each Cayenne model offers
three clear benefits: lower
servicing costs, more time on
the road and a more eco-friendly
use of resources.For more information on service
intervals, please refer to the
separate price list for the Cayenne
model range.

The lightweight exhaust systems
in the Cayenne models are made
f
rom special, long-life stainless
steel.
Short exhaust manifolds enable
rapid heating of the primary
catalysts, a basic prerequisite
for early and more effective
emissions control.
The engine management system
is also involved in preventing
emissions at source. Inside each
of the two primary catalytic
converters are two oxygen
sensors. These supply a real-time
analysis of exhaust gas compos-
ition. Based on this information,
the engine management system
can adjust the air/fuel mix as
required. This control system
ensures low emissions in all oper-
ating scenarios. The primary and
main catalysts offer high efficiency,
faster warm-up, a long service
life and consistently low emissions
(see page 104).
The Cayenne GTS has a sports
exhaust system as standard.

location is more accurate and
agility is enhanced, with minimal
disturbance on uneven surfaces.
The subframe is secured on
rubber mountings that minimise
road noise and thus enhance
the engine acoustics.
Made from lightweight high-
strength steel, the front
suspension subframe is specially
constructed to increase the
rigidity of the car.
The resulting benefits include
greater stability, greater comfort
and even greater active and
passive safety. In the event
of an accident, the subframe
deforms in a predefined manner
to provide additional protection
for the passenger compartment.
Front axle.

requires an equally responsive
chassis.

Rear axle.
A balanced chassis is essential
on any car and one of the major
challenges in vehicle design.
On all four Cayenne models, we
solved this problem using multi-
link rear 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 lower suspension links and
track rods have a special sheet
steel construction offering greater
strength. The upper links are
located high in the wheel arches
and can therefore be made from
lightweight forged aluminium.
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 easier
to load. A key advantage of the
rear axle design is its ability to
minimise dive and squat under
acceleration and braking. It also
uses active toe-angle control to
improve mid-corner stability and
compensate for sudden load
transfer, e.g., lift-off oversteer.
In short: a chassis you would
expect from Porsche. Specially
developed in Weissach.

that stores your preferred
wheel position as well as seat
and exterior mirror settings.
The steering column consists of
multiple collapsing sections linked
by three universal joints. A special
deformation element offering
70 mm of travel provides a high
level of safety in the event of front
impact.
Servotronic.
Servotronic is a speed-sensitive
power steering system available
as an option on all Cayenne
models.
At higher speeds, the steering
becomes firmer, inputs are more
precise and driver comfort is
greatly enhanced.
At lower speeds, it enables easy
manoeuvrability and parking. For optimum manoeuvrability, on
and off road, all Cayenne models
have variable-ratio steering
and special valve settings on
the power-steering system. Lock-
to-lock travel is a modest
2.65 turns, while the turning
circle is just 11.7 metres.
The steering wheel can be adjusted
by 50 mm for reach and 40 mm
for height. Both adjustment options
are electrically assisted on
