Engine
For fuel consumption and CO2 emissions please refer to page 127.
The engine will restart as soon as you
operate the clutch or, in cars with PDK,
release the brake. This fuel-saving inno -
vation is designed primarily for use in
towns or congested motorway traffic.
The auto start /stop function can be
deactivated and reactivated using a sepa -
rate but ton on the centre console. The
function may be deactivated automatically
under particular circumstances, e.g. in
extreme outside temperatures, when the
SPORT but ton is selected or when there
is low bat tery charge.
Cruise control.
This optional automatic speed controller
for the 19 to 149 mph (30 to 240 km/ h)
speed range is operated using a switch
on a separate control stalk on the steering
column. The advantages are claer, not
only can cruise control be used as a
means of staying within the speed limit,
it also helps you to save fuel by maintain -
ing a constant speed.
Electrical system recuperation.
For enhanced efficiency the new 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.
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 longer-
lasting driving pleasure.

Environment
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. 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
new Boxster models has a light alloy con -
tent of approximately 46 %. 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 technical requirements. In short, the new
Boxster is around 95
% recyclable.
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.
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 the fuel system has been minimised
thanks to the active carbon filter and the
multilayered material from which the fuel
tank is made. All fuel lines are made from
multilayered plastic, steel or aluminium.
Servicing.
Long service intervals offer clear advan
-
tages. For you, they reduce costs and
save time. For the environment, they
assist in the sparing use of consumables
and replacement parts. For full details
of service intervals, please refer to the
separate price list.
