Noise.
As paradoxical as it may seem, the
distinctive Porsche sound is also created
by what you don’t hear – the absence of
unwanted noise. Naturally, its main origin
is deep within the engine. But that’s
not all. Our holistic approach to vehicle
design also extends to the acoustics.
Which is why we’ve optimised them for
the entire car.
To minimise ‘play’ between components,
we’ve used stronger, lighter and more
temperature-resistant materials. This
reduces mechanical noise. Large-volume
silencers and air intake manifolds also
help to eliminate 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 a sound that is pure
Porsche.
Servicing.
With lengthy service intervals and long-
life components, vehicle maintenance is
kept to a minimum. 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 instance, feature automatic hydraulic
control.
Thanks to single-spark coils on each of
the cylinders, the entire ignition system
on the petrol-engined models, with
the exception of the spark plugs, is
maintenance-free.
These modest service requirements
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, 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. This Porsche principle
can be summed up in one word: sustain-
ability. The lightweight exhaust on the
Cayenne models, for example, is con-
structed from long-life stainless steel.
Every Porsche model is entirely free of
CFCs and components manufactured
using CFCs. All legal requirements in
respect of recoverability are fulfilled.
Materials are clearly labelled for
subsequent identification and sorting
to facilitate efficient recycling.
While more than 95 % of the car can be
recycled using current technologies, the
chances are your 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.
