Drive
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.

There is one fuel that will always be free.
Which is why we make the most of it.
Air intake system.
The Cayenne models are all
equipped with a resonance air
intake system. This simple
technology uses the pressure
waves generated by the inlet
valves to ‘force’ air into the engine.
The effect is enhanced in
the Cayenne, Cayenne S and
Cayenne GTS by a two-stage
intake manifold. This combines all
the benefits of a long intake tube
(higher torque at low rpm) with
those of a shorter length (more
power at higher rpm). On theCayenne GTS, performance is
enhanced by optimised airflow
management in the intake manifold.
Although ‘naturally aspirated’,
the Cayenne, Cayenne S and
Cayenne GTS provide high torque
ratings across the entire engine
speed range.
Drive
Pressure is often the key to performance.
Turbocharging system in the Cayenne Turbo.
The Porsche Turbo is synonymous
with performance, exhilarating
acoustics and the finest engineering.
The Cayenne Turbo has twin
turbocharger units arranged in
parallel. The low-volume intake
pipes combine with short exhaust
manifolds to achieve a rapid,
emphatic response.
Incoming air is passed through a
filter and compressed by the turbine
units. Its temperature is then
reduced in the intercooler system,
which improves cylinder charging
and limits thermal loads on the
engine.
Boost pressure reaches 1.8 bar
(absolute pressure) under full
acceleration from just 2,500 rpm.In normal road driving (part-throttle
mode), the pre-throttle boost
pressure is reduced in order
to
maximise fuel economy. When
the car is driven more assertively,
the
turbines are ‘pre-spun’ so
as to increase the pressure
available. When the throttle is
finally opened, the boost can
be applied immediately.
Both turbo units are cooled by
dedicated circuits from the main
engine cooling system.This solutionprevents oil degradation due to
overheating.
For the driver, the result is
seamless delivery of phenomenal
power and torque.

Drive
Maximum freedom requires total control.
Electronic engine management.
The electronic engine management
system provides coordinated
regulation of all engine functions
and associated systems in all
operating conditions.
The basic principle of engine
management is simple. Throughout
each journey, the system monitors
a range of input data and compares
it with corresponding sets of
reference values (‘maps’). Key
engine functions, such as ignition
and fuel injection, can be seamlessly
and automatically adjusted. The
results: optimum fuel economy and
lower emissions as well as greater
power and torque.One of the most important systems
controlled by engine management
is the electronic throttle, a
prerequisitefor Porsche Stability
Management
(PSM). Other major
functions include on-board diagnos-
tics and cylinder-specific knock
control featuring automatic compen-
sation for changes in fuel quality.
On the Cayenne, Cayenne S
and Cayenne GTS, the engine
management system controls
the variable-tract intake manifold.
On the Cayenne Turbo, it regulates
the turbo boost pressure.

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.
Drive
Committed to a purer driving experience.
Exhaust system.Spend less on servicing.
And more time on the road.
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

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.
Also

Environment
Servicing.
Although every journey is a pleasure
in a Porsche, there’s one you won’t
have to make too often. Thanks to
the lengthy service intervals and
long-life components, we may not
be seeing you for some time.
In the case of the oil filter, for
example, all that’s replaced is an
easily recyclable paper element.
The oil filter casing remains on
the car.
All moving parts inside the engine
are fully self-adjusting. The valve
clearances, for example, feature
automatic hydraulic control.
All camshafts have a zero-
maintenance chain-drive system.With single-spark coils on each
of the cylinders, the entire ignition
system, with the exception of the
spark plugs, is maintenance-free.
These modest servicing require-
ments mean less waste disposal
and fewer demands on natural
resources. They also lower the
cost of ownership while keeping
your car on the road.
Service intervals for the Cayenne
models are dependent on a range
of factors, including local fuel
quality. For full details of service
intervals in your country/region,
please consult the relevant price
list or contact your Porsche Centre.
Materials and recycling.
Owning a Porsche should be a
lasting pleasure with minimal
impact on the environment. That’s
why every Porsche is built to
endure both technically and in
terms of design. The lightweight
exhaust on the Cayenne models,
for example, is constructed from
long-life stainless steel.
Weight reduction is a fundamental
part of the Porsche design philoso-
phy. By using a greater proportion
of high-strength materials, e.g.,
special steels, cast aluminium
alloys and synthetic materials, we
have successfully reduced the
weight of each car and therefore
its fuel consumption. Every produc-
tion process we use at Porsche
is designed with the environment
in mind. Also, every Porsche model
is
entirely free of asbestos, CFCs
and
components manufacturedusing
CFCs. All legal requirements
in respect of recycling are fulfilled.
Materials are labelled in accordance
with VDA 260, enabling better
recycling of end-of-life vehicles and
individual parts and assemblies.
While more than 85 % of the car
can be recycled using current
technologies, the chances are
your new Cayenne may never need
recycling at all. After all, two thirds
of all the cars we have ever made
are still on the road today.
