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.

Performance needs sustained stability.
Fit ted as standard on the new Cayman,
18-inch alloy wheels are responsible for
maintaining the strong connection be -
t ween the vehicle and the road. A mini -
malist dual -arm spoke design accentuates
their sport y character – and yours. Tyre
sizes are 235/45 ZR 18 at the front and
265/45 ZR 18 at the rear.
The Cayman S is equipped as standard
with 19-inch wheels with a classic five-
spoke design. The t yre size at the front is 235/40 ZR 19 and 265/40 ZR 19 at
the rear.
Wheels up to 20 inches are available
from our list of options. The large rolling circumference helps to
improve comfort. At the same time, the
rolling resistance of the new generation

of t yres has been reduced, which, in turn,
helps to reduce fuel consumption.

Tyre Pressure m onitoring (TPm).
Optional Tyre Pressure Monitoring (TPM)
sends warnings to the on-board comput -
er’s display screen in the event of low
t yre pressure. The TFT screen in the

instrument cluster enables the driver to
check the pressure in all four t yres. The system updates quickly and

accurately af ter an engine start, t yre
pressure correction or wheel change –
for increased comfort and your safet y.

Another key advantage of PCCB is the
extremely low weight of the ceramic brake
discs, which are approximately 50 % light-
er than standard discs of a similar design
and size. As well as enhancing perfor -
mance and fuel economy, this represents a major reduction in unsprung and rotat
-
ing masses. The consequence of this is
bet ter road holding and increased com -
fort, particularly on uneven roads, as well
as greater agility and improved handling. Please note that circuit racing, track day
use and other forms of performance driv
-
ing can significantly reduce the service
life of even the most durable pads and
discs. As with conventional high-perfor -
mance braking systems, we recommend that all brake components be profession
-
ally inspected and replaced where neces -
sary after each track event.
e lectric parking brake.
The electric parking brake, which can be
activated and deactivated manually, is
released automatically as you pull away
with your seat belt fastened. A hill hold
function is integrated as standard for the
manual gearbox and for PDK. It assists
you in making a comfortable, smooth
and roll-free start on an incline. Whenever
you come to halt on an incline, this is
detected automatically and the braking
effect of the electric parking brake is

supplemented by application of the wheel
brakes. As long as a gear remains en -
gaged, the brake pressure is maintained
at all four wheels. To pull away, simply
apply throt tle. As soon as sufficient
starting torque is available, the brake
is
released and the vehicle moves off.
