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.

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.

Safety
On the road to independence, there is no
room for the slightest element of doubt.
The active and passive safet y concept
of the new Boxster models is designed
to ensure driving pleasure through peace
of mind.
Safet y is founded on a precisely engi -
neered chassis and high-performance
braking system. It also involves intelligent
control systems, such as Porsche Stability
Management (PSM), and depends on
an innovative body construction designed
to keep your roadster stable without
diminishing its agilit y. It is enhanced by an ingenious lighting concept featuring
powerful headlights, by assistance

systems that give you the information
you need and by an interior that provides
reliable protection in the event of an
accident.
Engineered body design.
The bodyshell of the new Boxster models
is based on an intelligent light weight
principle involving the composite con -
struction of aluminium and steel. The
use of dissimilar but precisely combined
components makes it possible to utilise
specific material properties exactly
It’s the same in the office as it is on the road:
performance needs a stable concept.
Safety.
where they are needed. Not only does
this provide a high level of safet y for
the driver, it offers a considerable weight
saving compared with the bodyshell of
the previous model. This is why the doors
of both luggage compartment lids are
made from lightweight aluminium.
The crumple zones in the front and
rear aprons feature integral light-alloy
bumpers, while impact absorbers offer
additional safet y. For the protection of
occupants, energy-absorbing padding is
used selectively in important areas within
the passenger cell.

If we are to continue to enjoy driving
pleasure, we need to look after our
environment. In other words, we need to
take responsibilit y. In an era of intensify -
ing debate about global climate change
and CO
2 emissions, every automotive
manufacturer is asking itself what it
has to offer in terms of environmental
protection. Our answer has long been
the same: Intelligent Performance –
a combination of high power output and
high efficiency.
In recent years Porsche has managed to
reduce fuel consumption across all model
ranges by a double - digit percentage compared with the respective previous
model, even though performance has
been increased in every generation.

This is made possible by an efficient drive
concept (e.g. direct fuel injection (DFI) and
VarioCam Plus), lightweight construction,
optimised aerodynamics and low rolling
resistance.
The environmental management team
at the Porsche Development Centre in
Weissach aims to demonstrate a high
level of environmental responsibility. Here,
technological developments are carried
out with environmental protection in mind.
The goal is to enhance performance –

and still care about tomorrow.

but, where possible, not at the expense
of the environment. We achieve this
goal with Intelligent Per formance, as
epitomised by the Boxster.
Exhaust emission control.
Vehicles manufactured by Porsche
demonstrate that even high-performance
sports cars can achieve moderate fuel
consumption and exhaust emission values
in their respective category.
This is achieved, on the one hand, through
the use of fuel - ef ficient technologies such
as auto start /stop, thermal management,
electrical system recuperation, direct fuel

2 emissions please refer to page 127. injection, VarioCam Plus and, in conjunc
-
tion with optional PDK, coasting mode.
On the other hand, newly developed
cataly tic converters provide ef ficient
emission control. While the stereo
Lambda control circuitr y controls and
monitors each cylinder bank separately.
For each exhaust tract, oxygen sensors,
together with the engine electronics
and injectors, regulate the composition
of the exhaust gas, while another
Lambda sensor on each cylinder bank
monitors pollutant conversion in the
respective cataly tic converter.

Fuel economy and recycling.
Intelligent lightweight construction has
been fundamental to the Porsche identit y
since 1948 for both technical and ecolog -
ical reasons. This forms the basis for
achieving low fuel consumption values in
conjunction with outstanding perfor -
mance. On the technical side, various compo
-
nents are made with a high proportion of
aluminium, magnesium, plastics 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 Boxster models has a light alloy con -
tent of approximately 46 %. On the ecological side, all materials used
are meticulously selected. We use only
innovative and environmentally friendly
components. All synthetic 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
ef ficient recycling. Recycled plastics are
used where they meet our exacting technical requirements. In short, the new
Boxster is around 95
% recyclable.
In addition, Porsche uses a high propor -
tion of environmentally friendly water-
based paints. For us, environmental
protection does not begin at the end of
a vehicle’s life. It starts at the planning
and development stage.
Fuel.
Both Boxster models are designed to
operate on fuels with an ethanol content
of up to 10 %. Ethanol has a positive
impact on the CO
2 balance since the
plants grown for the production of this
biofuel also absorb CO
2 from the atmos -
phere. 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. All fuel lines are made from
multilayered plastic, steel or aluminium.
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 service intervals, please refer to the
separate price list.
