Servicing.
In the Boxster models, the generator and
air conditioning system are driven by a
single self-adjusting belt. The drive chains
on the camshafts do not normally require
servicing. With the sole exception of the
spark plugs, the ignition system is also
maintenance-free in normal servicing. In
short, longer service intervals mean long er-
lasting driving pleasure.
initiation of targeted braking. During this
process, any braking by the driver is
boosted to achieve the maximum braking
force that the system is able to provide.
Electrical system recuperation.
For enhanced ef ficiency the Boxster
models are equipped with intelligent elec -
trical system recuperation. The vehicle
bat tery is recharged by the generator
predominantly under braking. Thanks to
this selective recharging, when you
request full driving power the maximum
possible output can be directed straight to
the road.
For increased safet y, the system also
readies the brakes whenever it detects
that the distance from the vehicle is
decreasing. However, the driver should
be prepared to intervene manually if
heavier braking is required. As soon as
the road ahead clears, your vehicle will
accelerate back up to the cruising speed
originally set.
Porsche Active Safe (PAS) issues an audi -
ble and a visual warning if the system
detects that your vehicle is approaching
the vehicle in front too quickly. This is
accompanied by a brief application of
brake force and, where necessary, the

save time. For the environment, they
assist in the sparing use of consumables

Fuel.
Both
Boxster models are 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 atmos -
phere. The release of hydrocarbons from
technical requirements. In short, the
Boxster is around 95 % recoverable.
In addition, Porsche uses a high propor -
tion of environmentally friendly water-
based paints. For us, environmental
protection does not begin at the end of
a vehicle’s life. It starts at the planning
and development stage.
On the ecological side, all materials used
are meticulously selected. We use only
innovative and environmentally friendly
components. All synthetic components
are easily recyclable and each material
is labelled to facilitate its separation for
recycling. The reduction in the number
of plastic variants helps to ensure more
ef ficient recycling. Recycled plastics are
used where they meet our exacting
On the technical side, various compo
-
nents are made with a high proportion of
aluminium, magnesium, plastics and
super high-strength sheet steel. The
materials used have been selected for
their abilit y to withstand load, yet they
are considerably lighter than conventional
steel. As a result, the bodyshell of the
Boxster models has a light alloy content
of approximately 46 %.
Fuel economy and recycling.
Intelligent lightweight construction has
been fundamental to the Porsche identit y
since 1948 for both technical and ecolog -
ical reasons. This forms the basis for
achieving low fuel consumption values in
conjunction with outstanding perfor -
mance.
