The SPORT but ton on the centre console
is fit ted as standard. When selected,
‘Sport ’ mode is activated to provide a
greater response and enhanced driving
pleasure. The engine reacts even more
directly to the accelerator pedal, the
rev-limiter is adjusted to a harder set ting
and engine dynamics are tuned for per -
formance driving. At the same time, the
auto start /stop function is deactivated
automatically.
With optional Porsche Doppelkupplung
(PDK), the shift points are reconfigured
to offer higher and even sportier rpm bands. Shift times are reduced and gear
-
shifts become firmer and more immedi -
ate, while throttle-blip downshifts are
accompanied by an even more emotive
engine sound. Coasting mode (p. 44) is
deactivated automatically. e lectrical system recuperation.
Another efficiency-enhancing feature of
the new Cayman models is intelligent
electrical system recuperation. The vehi-
cle 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 of the engine can be
directed straight to the road because
the electrical systems are supplied main -
ly by the energy that was stored in the
battery during the braking phase.
Servicing.
In the Cayman 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 short, longer service
intervals mean longer-lasting driving
pleasure.

Environment
Fuel economy and recycling.
Intelligent lightweight construction is, and
always has been, a fundamental aspect of
the Porsche philosophy – for both techni -
cal and ecological reasons. This combina -
tion forms the basis for achieving low fuel
consumption values in conjunction with
high performance. On the technical side,
various components are made with a high
proportion of alu minium, magnesium, plas -
tics 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
Cayman models has a light alloy content
of approximately 44 %.
On the ecological side, all materials used
are meticulously selected. We use only state-of-the-art components, with priority
given to products manufactured in a sus
-
tainable manner where possible. All syn -
thetic 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 efficient recycling. Recycled
plastics are used where they meet our
exacting technical requirements.
In short, the new Cayman is around 95 %
recoverable.
In addition, Porsche uses a high proportion
of environmentally friendly water-based
paints. For us, environmental protection
does not begin with the vehicle manufac -
turing process. It starts at the planning
and development stage.
Fuel.
The new Cayman models are designed to
operate on fuels with an ethanol content of
up to 10 %. Ethanol has a positive impact
on the CO2 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 thanks to the
active carbon filter and the multilayered
material from which the fuel tank is made.
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 ser -
vice intervals, please refer to the separate
price list.
