Thermal management.
The intelligent thermal management
system in the Cayman models regulates
the temperature in the engine and gear -
box
to reduce friction losses that occur
during the warm-up phase.
Thanks to the purposeful control of heat
flow and on-demand, gradual activation
of the various cooling circuits, the engine
and gearbox warm up to normal operat -
ing temperature more rapidly. The result -
ing reduction in friction also reduces fuel
consumption and CO
2 emissions. During
sporty driving, thermal management also
acts to reduce temperatures so as to
maintain a high degree of performance. Our cross-flow cooling system, as used
in motorsport, supplies each engine cylin -
der uniformly with coolant, which protects
all valves against thermal overload and,
therefore, premature wear. This improves
combustion and keeps emissions, fuel con -
sumption and noise comparatively low.
exhaust system.
In the new Cayman models, each cylinder
bank has its own stainless-steel exhaust
tract. Downstream of their respective rear
silencer, the tracts converge into a con -
necting tube and a single (Cayman) or t win
(Cayman S) tailpipe. The stereo Lambda
control circuitr y
controls and monitors each cylinder bank
separately. For each
exhaust tract, four
corresponding oxygen sensors regulate
the composition of the exhaust gas and
monitor the performance of the catalytic
converters. The separate
tracts enable
the exhaust gas to flow more
f re e l y. T h e
resulting reduction in pressure loss has
a positive impact on power output, torque
and the unmistakable engine sound.
Available as an option for the new Cayman
models is the sports exhaust system*
including sports tailpipe. It produces an
even more resonant Porsche sound.

Storage compartments.
You could make an escape from every
-
day life or you could fully embrace it.
The choice is yours. It ’s also a lit tle
example of the personal freedom that
the new Cayman models afford you –
not only with performance, but also with
everyday practicalit y. In addition to the
luggage compartment at the front, the luggage space under the wide-opening
rear hatch is impressively roomy.
The lockable glove compartment and
the compartment with a power socket
under the armrest in the centre console
provide plent y of space. As does the
open compartment to the front of it. In
conjunction with the smoking package,
the open compartment makes way for
an ashtray with a lid. Other storage
features include two compartments in
each door, a net in the passenger foot -
well,
clothes hooks on the seat backrests
and two practical cupholders above the
glove compartment.
Front luggage compartment.
Increased storage space is another facet
of your personal freedom. The front
luggage compartment has a capa cit y of
150 litres and is lined with black carpet.
r ear luggage space.
The rear luggage space is both conveni -
ent and functional. Comprising the shelf
above the engine cover and the luggage
compartment behind, it comfortably
holds even long items of luggage such
as sports equipment. A total capacit y

of around 275 litres is available. As part
of the interior, it is lined with carpet in
the interior colour. The luggage protec -
tion bar and inlay are made of brushed
aluminium. Concealed by the inlay are
the service openings for the coolant and
engine oil tanks. Storage compartments in
the upper luggage compartment provide
additional space for your belongings. The separate Driver’s Selection by
Porsche Design catalogue contains
a selection of matching luggage
accessories.
Its most important feature:
freedom of choice.
