The secret of performance?
Efficiency.

the class, every Porsche
combines high performance
Exhaust emissions.
The Cayenne models are all
equipped with the very latest
emissions technologies. As a
result, they comply with both the
stringent EU4 exhaust emissions
with only moderate emissions.
On the Cayenne models, this is
achieved using an advanced
engine concept featuring direct
fuel injection, VarioCam Plus
(V8 engines) or variable valve
timing (V6 Cayenne) as well asreduced sooner when starting
from cold.
Another important feature is
the use of twin oxygen-sensor
circuits. Each bank of cylinders
has a separate control system

Environment
Fuel system.
We have also applied the highest
engineering standards to protect
the environment from fuel
evaporation. The non-return
fuel supply system provides a
considerable reduction in vapour
emissions. The fuel lines are
partly constructed from steel,
while those carrying vapour are
made from multi-layer plastics.
A large active-carbon filter and
multi-layer plastic fuel tank help
reduce evaporation even more.
A leak detection pump is also
included to monitor the integrity
of the fuel tank system.
Acoustics.
Think of a Porsche and what
do you hear? One of the most
distinctive sounds on the road.
A sound created not just by the
engine, but also by the absence
of unwanted noise. To minimise
Fuel economy.
At Porsche, we’re using innovative
technologies to increase perform-
ance while enhancing fuel economy.
With direct fuel injection (DFI),
we’ve made our engines more
efficient in terms of both output
and consumption. DFI is combined
with VarioCam Plus in the V8 engines
and variable valve timing in the
Cayenne V6. As well as improving
performance and economy, both
of these systems help to minimise
engine emissions. The low-drag
exterior on each Cayenne model
further improves efficiency.
Fuel.
All Porsche models are already
compatible with a fuel ethanol
content of up to 10 %. Ethanol
has a positive impact on the carbon
dioxide balance since the plants
grown for its production absorb
carbon dioxide from the atmosphere.
‘play’ between engine components
under all load conditions, we’ve
used stronger, lighter and more
temperature-resistant materials.
This reduces mechanical noise
and eliminates the need for engine
encapsulation. Large-volume
silencers and air intake manifolds
also help to minimise noise –
throughout the life of the car.
Tyre noise has been drastically
reduced in collaboration with
our official tyre partners. Wind
noise levels have also been
lowered thanks to aerodynamic
refinements.
All that remains is the Porsche
sound – as legendary as ever.

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.

proved, the engine can be started
as normal.
When the key is removed from the
ignition, the steering column is
automatically locked to provide
additional security.
Porsche Entry & Drive.
With this optional system, you can
reduce the inconvenience of a con-
ventional key.
The moment you touch the door

code is accepted, the doors are
unlocked. To start or stop the
engine, simply push the ignition
button.
To lock the car on leaving, all you
have to do is press a button on the
outside of the door handle. Porsche
Entry & Drive then secures the car
doors, arms the immobiliser and
locks the steering column.
Preparation for vehicle

Five discrete audio channels (front
left, front right, centre, surround
left and surround right) plus a low-
frequency effects channel provide
naturalistic sound with precise spatial
location of voices, instruments,
sound effects, etc., at the front
and rear of the car. A 360-degree
soundstage, its realistic 3D audio is comparable with a concert hall
or cinema.
Naturally, you can also play
conventional CDs, either in stereo
mode or as surround sound
