Thermal management.
The Boxster models feature a new version
of thermal management to reduce friction
losses that arise during the warm-up
phase.
Thanks to the selective control strategy
and on-demand, gradual activation of the
various cooling circuits, the engine and
gearbox warm up to normal operating
temperature more rapidly. The conse -
quent reduction in friction also reduces
fuel consumption and CO
2 em issio ns.
During sporty driving, thermal manage -
ment also acts to reduce temperatures
so that a high level of performance is
maintained. Our cross-flow cooling system, as used

in motorsport, supplies each engine
cylinder uniformly with coolant, which
protects the valves against thermal
overload and, therefore, premature wear.
This improves combustion and keeps
emissions, fuel consumption and noise
comparatively low.
Exhaust system.
In the new Boxster models, each cylinder
bank has its own stainless-steel exhaust
tract. Downstream of their respective
rear silencer, the tracts converge into
a connecting tube and a single (Boxster)
or t win (Boxster S) tailpipe. The stereo
Lambda control circuitr y controls and monitors each cylinder bank separately.
For each exhaust tract, four correspond
-
ing oxygen sensors regulate the composi -
tion of the exhaust gas and monitor the
performance of the catalytic converters.
Having separate tracts means that the
exhaust gas can flow more freely. The
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 Boxster
models is the sports exhaust system
1)
including sports tailpipe. It produces an
even more resonant Porsche sound.

Wheels.
The standard wheels on the new Boxster
models have been enlarged by one inch
compared with those of the previous
models. Made from a light weight alloy, the
larger wheels reinforce the car’s imposing
presence and further improve sport y
performance. The new Boxster is equipped with 18-inch
wheels. Their minimalist five-spoke design
is sport y and elegant in equal measure.
Tyre sizes are 235/45 ZR 18 and 265/45
ZR 18 at the front and rear respectively.
The Boxster S has 19-inch wheels with
a dynamic dual-spoke design. The t yre
size at the front is 235/40 ZR 19 and
265/40 ZR 19 at the rear.
The larger rolling circumference improves
comfort and performance. At the same time, the rolling resistance of the new gen
-
eration of t yres has been reduced which,
in turn, helps to reduce fuel consumption.
Wheels up to 20 inches are available as an
option.
Tyre Pressure Monitoring (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 4.6-inch TFT screen in the
instrument cluster enables the driver to
check the pressure in all four t yres. The system updates quickly and accurately
after an engine start, t yre pressure cor
-
rection or wheel change – for increased
comfort and safet y.

Another key advantage of PCCB is the
extremely low weight of the ceramic
brake discs, which are approximately
50 % lighter than standard discs of similar
design and size. As well as enhancing
performance and fuel economy, this represents a major reduction in unsprung
and rotating masses. The consequence

of this is bet ter road holding and increased
comfort, particularly on uneven roads,
as well as greater agilit y and improved
handling. Please note that circuit racing, trackday
use and other forms of performance

driving can significantly reduce the
service life of even the most durable
pads and discs. As with conventional
high-performance braking systems, we recommend that all brake compo
-
nents be professionally inspected and
replaced where necessary after every
track event.
Electric 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 engaged, the brake pressure
is maintained at all four wheels. To pull
away, simply apply throttle (manual gearbox: apply throt tle and release the
clutch pedal). The wheel brakes are
released as soon as sufficient starting
torque is available and the parking brake
is released as the vehicle moves off.
