What use is expertise if it isn’t put into
practice and applied to the road?
In the Boxster, the 2.7-litre horizontally
opposed six cylinder engine delivers
195 kW (265 hp); in the Boxster S, the
3.4 - litre equivalent generates 232 kW
(315 hp). Both mid-mounted engines
feature direct fuel injection (DFI) and Vario -
Cam Plus for a significant increase in both
power output and efficiency. The SPORT
but ton on the centre console is fit ted
as standard and opens up even more agile
responses. Power is transmit ted to the
wheels by a light weight six-speed manual
gearbox or the optional 7-speed Porsche
Doppelkupplung (PDK).
A series of innovative technologies is key
to achieving exemplary efficiency. As
standard, these include the auto start/stop
function, electrical system recuperation,
energy-saving electromechanical power
steering, intelligent thermal management
and, in conjunction with PDK, the coast -
ing function. The result, The result is a
significant reduction in fuel consumption
and, therefore, a reduction in CO
2 emis -
sions of up to 16 % compared with the
previous model (depending on the equip -
ment variant).

Engineering.
enhanced Porsche Active Suspension
Management (PASM) of fers continuous
adjustment of damping forces based on
the selected mode. Dynamic per formance
can be further improved with optional
Porsche Torque Vectoring (PTV). The
optional Sport Chrono Package includes
dynamic gearbox mounts for the first
time. They contain a fluid with magnetic
properties, which enables them to adapt
instantly to driving conditions and counter -
act the effects of inertia. The results are
perceptibly more stable handling during
performance driving, as well as a higher
level of ride comfort. The brakes at the front axle have a
greater
surface area for improved braking perfor -
mance. The Porsche Ceramic Composite
Brake (PCCB) is available as
an option.
The hood on the new Boxster models
makes it easy to clear your head. Fully
electric, it opens and closes in around nine
seconds and is operable up to a speed of
approx. 30 mph (50 km/ h).
The intelligent lightweight construction,
which uses aluminium for substantial
parts of the bodyshell, doors and luggage
compartment lids, helps to achieve an
excellent power-to-weight ratio.

Brakes.
Porsche brakes set standards worldwide
for stopping power and stability. For
the new Boxster models, braking per for -
mance is as essential as driving perfor -
mance.
Both models are equipped with four-
piston aluminium monobloc fixed calipers
at the front and rear. This design means
that, not only are the brakes extremely
resistant to deformation, they are light -
weight for a particularly fast and sensitive
braking response.
The new generation of brake caliper at
the front axle, combined with enlarged
brake pads and the newly developed
brake booster, has managed to improve braking and component stability even
during continuous use. These two charac
-
teristics have also been optimised by the
newly developed brake ventilation system
with a modified air spoiler at the front
and rear axles.
The enhanced dynamics of the Boxster
and Boxster S also demand appropriate
brake discs. All Boxster brake discs are
internally vented and cross-drilled for
improved braking in wet conditions. On
the Boxster S, the diameter of the front
brake discs has been enlarged by 15 mm
to 330 mm. At the rear, the diameter is
the same as on the Boxster – 299 mm
The brake calipers on the Boxster and
Boxster S are black and red respectively.
Porsche Ceramic Composite Brake
(PCCB).
From the start, Porsche has been synon -
ymous with motorsport. Ever since
1948, when we found our identit y on the
racetrack, we have taken the experience
we have gained and applied it to the
road. The optional Porsche Ceramic
Composite Brake (PCCB) is a fine exam -
ple. This brake system has already had
to cope with the harshest requirements
of motor racing and is fit ted in cars
that compete in demanding events such
as the Porsche Mobil 1 Supercup.
The cross-drilled PCCB ceramic brake
discs for the new Boxster have a diame -
ter of 350 mm front and rear for even
more formidable braking performance. The use of six-piston aluminium mono
-
bloc fixed brake calipers on the front
axle and four-piston units at the rear –
all finished in yellow – ensures extremely
high brake forces which, crucially, are
exceptionally consistent.
PCCB enables shorter braking distances
in even the toughest road and race
conditions. Excellent fade resistance
ensures greater balance when slowing
from racetrack speeds.

Chassis
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.
