Fuel and fuel economy.
Increasing performance while enhancing
fuel economy. The Cayenne comes in a
choice of three different drive systems,
each featuring state-of-the-art technol-
ogy for high efficiency and relatively low
fuel consumption. The petrol-engined
models already operate on fuels with
an ethanol content of up to 10 %. This
further improves the carbon dioxide
balance since the plants grown for the
production of biofuels absorb carbon
dioxide from the atmosphere. As you
can see, for the benefit of the environ-
ment, we are continually working on
making our cars more efficient – as well
as compatible with alternative fuels.
While ensuring that they remain one
thing: a thoroughbred Porsche.
Fuel system.
We have also applied the highest stand-
ards to our petrol-engined models in
order to protect the environment from
fuel evaporation. The non-return fuel
supply system provides a considerable
reduction in vapour emissions. The lines
carrying vapour are made from multi-
layer plastics. A large active-carbon
filter and multi-layer plastic fuel tank help
reduce evaporation still further.
