2011 PORSCHE BOXSTER S light

Even when you want to make a break
from everyday life, you should still keep
your feet on the ground.
The chassis of the new Boxster models
are an excellent match for the powerful
engines. Axle components are made
predominantly of aluminium. This light -
weight material helps to keep the weight
of the vehicle and its unsprung masses
low, which reduces fuel consumption,
improves comfort and increases agility.
The wide track is a prominent feature to
provide additional stability and enhanced
comfort, the wheelbase has been extended
by 60 mm compared with that of the
previous model. The new independent
suspension features lightweight spring-strut
a
xles with longitudinal and transverse links
and, at the front, cross members that
have been refined for optimum control.
As a result, each wheel moves precisely
to ensure excellent directional stability
and superior handling in all situations.
What does this mean for the driver? The
sophisticated engineering of the chassis,
combined with the mid-engined layout,
achieves impressive dynamic performance.
Body roll and pitch have been practically
eliminated to offer a level of agilit y that
turns each corner into an incomparable
experience.
A love of freedom is no reason
to lose self-control.

actively and continuously regulates the
damping force for each wheel according
to the
road conditions and driving st yle.
In addition, the suspension is lowered
by 10 mm.
The driver can select bet ween t wo
dif ferent modes: ‘Normal’ which is a
blend of performance and comfort,
and ‘Sport ’ where the setup is much
firmer. Depending on the mode selected,

therefore, PASM can be both sportier
and more comfortable than the standard
chassis. The PASM control unit evaluates
the driving conditions and modifies the
damping force on each of the wheels in
accordance with the selected mode.
Sensors record the body movements that
accompany powerful acceleration, brak -
ing or uneven road surfaces. This enables
intelligent adaptation of damper stif fness
for the selected mode, optimising contact
bet ween each individual t yre and the road
and reducing pitch.

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

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.

Porsche Stability Management (PSM).
Enhanced Porsche Stability Management
(PSM) is fit ted as standard. This system
automatically maintains stability even
at the limits of dynamic driving perfor -
mance. Sensors continuously monitor
the speed, yaw velocit y and lateral
acceleration of the car. Using this
information, PSM is able to calculate the
actual direction of travel at any given
moment. If the car begins to oversteer or
understeer, PSM applies selective braking
on individual wheels in order to restore
stability. Under acceleration on wet or low-grip
road surfaces, PSM improves traction –
as well as agilit y and safet y – using the
automatic brake differential (ABD) and
anti-slip regulation (ASR). Integrated ABS
is designed to minimise braking distances.
If you prefer an ever sportier drive, PSM
can be switched off. For your safet y,

however, PSM remains set to intervene if
the vehicle is braked and ABS assistance
is required. ABS and ABD remain switched on at all times. Also included with PSM
are engine drag torque control (EDC),
precharging of the brake system and
brake assist. If you suddenly release the
accelerator pedal, PSM automatically
prepares for your next action: the braking
system is precharged so that the brake
pads are already in light contact with the
brake discs. Maximum braking power is therefore achieved much sooner. Brake
assist detects a panic braking situation
and generates the brake pressure
required for maximum deceleration.

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

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.

Roll-over protection.
Dual roll - over protection creates survival
space in the event of a roll-over or side
impact. The front roll-over protection
element is made from super and ultra
high -strength steels. The rear roll - over
bars located behind the seats are a composite construction of aluminium and
steel. They are fully trimmed to blend in
and provide an excellent level of safet y.
The upper seat belt guides are mounted
on the roll-over bars for easier fastening.
Airbags.
To protect the driver and passenger, the
new Boxster models are equipped with
full-size airbags, which are inflated in

t wo stages depending on the severit y
and t ype of accident (e.g. frontal or offset
frontal). In less serious accidents, the airbags are only partially inflated, thereby
minimising discomfort to the occupants.
In addition to the central airbag control
unit on the transmission tunnel, a pair of
impact sensors is located near the head
-
lights. This allows a crash to be detected and evaluated far sooner and with

considerably greater accuracy.Porsche Side Impact Protection
System (POSIP).
Both new Boxster models are equipped
as standard with the Porsche Side Impact Protection System (POSIP). It comprises
t wo side airbags on each side. An integral
thorax airbag is located in the outer side
bolster of each seat, while the door panels
each contain an upwards-inflating head
airbag. Each thorax airbag has a volume of
10 litres and each head airbag 15 litres, ensuring excellent protection in the event
of a side impact even with the hood open.
POSIP additionally includes steel side
impact protection elements in the doors.

Lights.
Lights will always be an essential safet y
feature, but we go one step further by
using them as part of an extraordinary
styling concept.
Clear glass halogen headlights are fit ted
as standard on the Boxster. The Boxster S
is equipped as standard with Bi-Xenon
headlights. On both models, LED day time running lights and position lights are
housed in a separate auxiliary light unit
above the outer air intakes. LEDs provide
powerful illumination, respond extremely
rapidly to driver input, offer a longer

service life and have an unmistakable
appearance.
LED technology opens up entirely new
possibilities for designers. Not only are LEDs capable of fulfilling all the functions
of the imposing taillights and third brake
light, they are integral to safet y and

create a look that is unmistakable, day
and night.
Bi-Xenon headlights including
Porsche Dynamic Light System (PDLS).
The optional Porsche Dynamic Light
System (PDLS), which comprises Bi -Xenon headlights with halogen main-beam head
-
lights, a headlight cleaning system and
automatic dynamic range control, provides
uniform illumination of the road whether
dipped or main beam is selected.
The dynamic cornering light function
swivels the main headlights towards the
inside of a bend based on steering angle
and road speed. Put simply, a greater part of the road ahead is illuminated the
moment you enter a bend. The system also includes a speed-sensitive
headlight range control function. With
adaptive light systems, it is possible for
the maximum range of the dipped beams
and their lighting power to be adjusted as
a function of the speed of the vehicle.
PDLS takes care of this automatically in t wo stages. Stage 1 is the basic position,
optimised for driving at lower speeds
such as in cit y traffic. Stage 2 is designed
for driving at faster speeds, such as
when on the motorway. Another function
of PDLS is the adverse weather function.
Activated when you switch on the rear
fog light, it reduces the effect of reflection
phenomena in poor visibility conditions.
Automatic headlight activation.
In the new Boxster models, automatic
headlight activation is available as
standard. The system automatically
switches bet ween day time running lights
and dipped beam based on ambient
lighting conditions.
