Fuel.
The new 911 is already designed
to operate on fuels with an
ethanol content of up to 10%.
Ethanol has a positive impact on
the CO
2
balance since the plants
grown for the production of this
biofuel also absorb CO
2
from the
atmosphere.
The release of hydrocarbons
from the fuel system has been
minimised. This is achieved
through an active carbon filter
and a special coating on the fuel
tank. The high-pressure section
of the fuel system is made of
stainless steel, while vapour-
carrying lines are made from
multi-layered plastic.
Noise.
The new 911 complies with all
applicable noise regulations
without any form of engine encap-
sulation.To achieve this, noises
are eliminated at source. Engine
parts are stiff, moving parts are
lightweight and tolerances are
kept to a minimum. Large-volume
silencers and resonators in the
air intake system minimise noise
further. For the entire service life
of the vehicle.
Servicing.
Long service intervals offer
clear advantages. For you: lower
costs and saved time. For the
environment: the use of fewer
consumables and replacement
parts. For full details of service
intervals, please refer to the
separate price list.
