In models with the V8 engine,
exhaust gas cleaning is supported
by an air injection system. A com-
pressor pumps extra air into the
exhaust tract during the catalytic
converter warm-up phase for
faster heating and, therefore,
lower emissions.
Other measures for improving fuel
economy are the Auto Start/Stop
function (p. 50) and electrical
system recuperation, whereby the
vehicle battery is charged pre-
dominantly under braking. Under
acceleration, on the other hand,
the charging current of the regu-
lated alternator is reduced so that
the engine does not need to work
as hard to charge the battery.
Lightweight construction and
recycling.
A fundamental objective in the
development of any Porsche is
intelligent lightweight construction.
For both economical and ecologi-
cal reasons. This forms the basis
for low fuel consumption values in
conjunction with outstanding
performance. It is economical
thanks to the high proportion of
aluminium cast alloys, plastics
and super-high-strength sheet
steel used. This is substantially
more stable and lighter than
conventional steel. The Panamera
models have a bodyshell with a
lightweight-metal content of 23 %.
For example, the bonnet, doors,
front wings and rear lid are made
of aluminium, which saves on
weight and has a positive effect
on the environmental balance:
according to eco balance sheets,
the extra energy used and the
higher emissions incurred in the
manufacturing of aluminium
are more than compensated by
the savings on fuel after only a
relatively short distance.
It is also responsible because all
materials used are meticulously
selected. We use only innovative
and environmentally friendly com-
ponents. All lightweight materials
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
efficient recycling. Recycled plas-
tics are used where they meet our
exacting technical requirements
In all, the Panamera is approxi-
mately 95 % recyclable.
In addition, Porsche uses only
environmentally friendly water-
based paints, thus reducing
the need for solvents both in pro-
duction and in the workshop.
The Panamera is also absolutely
free of asbestos, CFCs and
components manufactured using
CFCs because, here at Porsche,
environmental protection does
not begin at the end of a vehicle’s
life. It starts at the planning and
development stage.
