Porsche Active Suspension
Management (PASM).
The optional PASM is an elec -
tronic damping control system.
On the Boxster models, the
suspension has been tuned to
match the high power of the
engine. PASM actively and con -
tinuously 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. 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 monitor the movement
of the vehicle body, for example,
under heav y acceleration and
braking or on uneven roads. The
control unit tunes the dampers

to the optimum hardness for the
selected mode to reduce roll and
pitch still further and to increase
contact bet ween each individual
wheel and the road.
In ‘Sport ’ mode, the suspension
is set to a harder damper rating.
On uneven roads, PASM imme-
diately switches to a softer
rating within the ‘Sport ’ setup
range, thereby improving con-
tact bet ween the wheels and the
road. When the road surface
improves, PASM automatically
reverts to the original, harder
rating.
If ‘Normal’ mode is selected and
the driver’s st yle becomes more
assertive, PASM automatically
switches to a harder rating within
the ‘Normal’ setup range.
Damping becomes harder, and
driving stabilit y and road safet y
are increased.
Mechanically locking rear
differential.
Are you a fan of sport y driving?
In your spare time, do you
enjoy the occasional outing on
the racetrack? Then you
shouldn’t do without the optional
mechanically locking rear differ -
ential available in conjunction
with 18-inch or 19-inch wheels.
It further enhances the traction
of the driven rear wheels on
uneven roads and when acceler -
ating out of tight bends. Road
holding at the limits of perform -
ance is even more impressive.
The car holds its course bet ter
and so PSM intervenes less often.
In other words, sheer driving
pleasure and faster lap times.

Sport Chrono Package.
The Boxster combines open -top
driving with performance which
at Porsche has its origins on the
racetrack.
As an option, for both models we
offer the Sport Chrono Package
which enables even sportier tuning
of the chassis and engine and
guarantees even more driving
pleasure.
Selecting the SPORT but ton

on the centre console activates
‘Sport ’ mode, which makes
throt tle the response significantly
more immediate, adjusts the
rev-limiter to a harder set ting,
and tunes the engine dynamics
for performance driving.
The optional Porsche Active

Suspension Management (PASM)
also switches to ‘Sport ’ mode,
which of fers harder damping and
more direct steering and, there-
fore, bet ter road holding.

With the optional PDK in auto -
matic mode, gearshif t points are
delayed until the upper rev range.
The shif t times are shorter, the
gear changes sportier. At low rates
of deceleration, the system
initiates a swif ter, brake-induced
downshift. In manual mode, gear
changes are faster and more
dynamic.
In ‘Sport ’ mode, the PSM (p. 63)
intervenes later for increased
longitudinal and lateral dynamics.
PSM now affords greater
manoeuvrabilit y under braking
and exit acceleration, especially
at low speeds.
For maximum dexterit y, PSM can
be set to standby while the car is
still in ‘Sport ’ mode (p. 63). For
safet y, it is set to intervene auto -
matically only when ABS assist -
ance is required on both the front
wheels.
A key component of the Sport
Chrono Package is the swivel-
mounted in the centre of the
dashboard with analogue and
digital display.
In combination with the optional
Porsche Doppelkupplung (PDK),
the Sport Chrono Package of fers
t wo additional functions that
are activated by the SPORT PLUS
but ton.
First, ‘Launch Control’, which
ensures you achieve the fastest
possible rate of acceleration
from a standing start – on the
race track, for example. ‘Launch
Control’ is operated via the
SPORT PLUS but ton with the ‘D’
or ‘M’ drive position selected.
Whilst the driver depresses the
brake pedal with the left foot,
the right foot depresses the
accelerator pedal to the floor.
With the accelerator in the kick -
down position, the system
detects the driver’s request for
Launch Mode and revs the
engine to an optimum speed of
approximately 6,500 rpm.
Boxster | Chassis
Engine torque increases and the
clutch closes slightly. The mes -
sage ‘Launch Control ’ appears
in the display on the PDK steer -
ing wheel. The driver now quickly
releases the brake – and pre -
pares for maximum acceleration.

Second, the ‘motorsport- derived
gearshif t strategy’. Using this,
PDK is geared up for maximum
shif t speed, the shortest possible
shif t times and optimum shif t
points for maximum acceleration
– ideal for the racetrack.
Sport Chrono Package Plus.
On request, the optional Porsche
Communication Management
(PCM, p. 83) can be combined
with the Sport Chrono Package
Plus. In addition to the functions
of the Sport Chrono Package,
it includes a personal memory
function in the PCM and a per-
formance display for evaluating
lap times.

Boxster | Safet y
Passive safety: engineered
design.
The deformation zone at the
front of the vehicle contains a
system of longitudinal and lateral
members which absorb the
energy in the event of an impact.
The fuel tank and fuel lines are
safely positioned outside the
deformation zone. Together with
the rigid side structures, high-
strength steel elements in the
doors provide exceptional side-
impact protection. The reinforced
windscreen frame and the roll-
over bars positioned behind the
seats provide an ef fective barrier
if the car overturns. Energy-
absorbing materials are used at
key points throughout the passen -
ger compartment.
Both Boxster models are fit ted
as
standard with an airbag system

comprising t wo full-size front air -
bags as well as dedicated head
and thorax airbags (POSIP, p. 67)
on each side. This arrangement
ensures optimum upper-body

protection, even when the hood is
open. For added comfort and
safet y, the three-point belts have
integrated force limiters and
pretensioners.
Roll-over protection.
The front area of the cockpit is
protected by a robust steel
element integrated invisibly into
the windscreen frame. The rear
roll-over bars are made from high-
strength steel and are located
behind the seats. Their flat tened
form ensures high safet y, and
harmoniously follows the lines of
the seat backrests. The upper
seat-belt anchorage points are
at tached to the bars for greater
accessibility and comfort.
Porsche Side Impact
Protection (POSIP).
Both Boxster models are equipped
with Porsche Side Impact
Protection (POSIP) as standard.
This consists of t wo airbags on
each side. The outer bolsters of
the seats contain a thorax air-

bag and each door contains a head
airbag. Each has a volume of
around 8 litres, ensuring high
protection in the event of a side
impact, even when the hood is
open. The passenger cell is also
shielded by side impact protec -
tion beams in the doors.
Child seats.*
For our youngest Boxster pas-
sengers, the Porsche Tequipment
range of accessories includes
child seats and the necessary
preparation. This comprises an
ISOFIX fixing bracket for mount -
ing the Porsche child seats, and
a key switch to deactivate the
passenger airbag.

Water-repellent side windows.
The surfaces of the side windows
are treated with a water-repellent
coating so that not only water but
also dirt runs away more easily,
thereby providing optimum visibil-
it y even in poor weather.
ParkAssist.
As soon as reverse gear is
engaged, the optional Park Assist
is automatically enabled. If you
move too close to an obstacle, a
warning signal begins to sound,
becoming faster until the car stops.
The sensors of the optional
Park Assist are neatly concealed in
the rear bumper.
Anti-theft protection.
The Boxster models are equipped
with an immobiliser with in-
key transponder. In addition, the
Boxster S has an alarm system
with contact-sensitive exterior pro -
tection as standard. On request
,
radar-based interior surveillance
is available which protects
the interior of the vehicle when
the hood is closed. For the
Boxster, the alarm system and
radar interior surveillance are
both available as options.
Boxster | Comfort
Vehicle tracking system.
In conjunction with the alarm
system, this optional preparation
enables future installation of a
vehicle tracking system available
from Porsche Tequipment. It
makes it possible to locate a
stolen vehicle across most of the
countries of Europe. The package
includes a special wiring loom
and a higher-capacit y bat tery.
A tilt sensor is included.
Two luggage compartments.
Two carpet-lined luggage compart -
ments are available. The front
loadspace capacit y is 150 litres,
with 130 litres at the rear –
even when the hood is lowered.
At the front there's enough room
for the large trolley from the
Porsche Travel System, while
the rear can accommodate the
Porsche golf bag. The luggage
compartment covers are made
of light weight aluminium.
A service hatch located in the
rear luggage compartment

enables easy refilling of coolant
and engine oil.

Porsche and sound – inseparable
– not only in terms of the engine,
but also in the interior acoustics.
The audio system is specially
adapted to the Boxster models.
The result is a rich and more
enjoyable sound – both inside
and outside the car.
CDR-30 audio system.
Both Boxster models are equipped
as standard with the CDR-30
audio system with 5-inch display
(monochrome) and MP3-com -
patible CD drive. An integrated
six-disc CD autochanger is avail -
able as an option.

Calling the tune,
even when it comes to communication.
The FM dual tuner with RDS
diversit y, a total of 30 memory
presets, dynamic autostore

and speed-sensitive volume con -
trol are, as usual, all part of the
standard package. Just like the
high-qualit y sound, which is deliv -
ered by t wo high-range speakers
in the dashboard, t wo low-range
speakers in the door trims and
t wo 25-wat t output stages. For
an even more impressive sound
experience, you could opt for
the Sound Package Plus or BOSE®
Surround Sound System.
Controlling the CDR-30 audio
system could not be more simple:
the function keys ensure that all
the main functions are directly at
your finger-tips, and it is also pos -
sible to conveniently control all
of the most important functions
using the but tons on the optional
multifunction steering wheels.
Porsche Communication
Management (PCM) including
navigation module.
PCM is available on request for
both Boxster models. As the
central information and communi -
cations system, it can be used
for many dif ferent applications
and its ergonomic design makes
it easy and comfortable to
operate.

Boxster | Comfort
The main feature is the 6.5-inch
colour touchscreen with a
durable, easy-to - clean coating.
Functional, innovative and easy
to use, you will find the display
very clearly presented and a
maximum of five list entries per
page enable you to operate the
unit quickly and safely. Alterna -
tively, you can also operate the
PCM using conventional but ton
controls.

BOSE® Surround Sound System
for PCM and CDR-30.
The optional BOSE® Surround
Sound System is compatible with
both the CDR-30 audio system,
which comes as standard, and
the optionally available PCM.
Developed specifically for Porsche,
it has been optimised for the
Boxster models. A total of 11 loud -
speakers, including an active sub-
woofer and central speaker, and
a seven-channel digital amplifier
with a total output of 385 wat ts,
combine to produce a truly memo -
rable sound experience.
During audio playback from audio
or video DVDs (only with the
optional PCM), the system is able
to make full use of the impressive
sound spectrum of 5.1 digital
recordings. With music in the 5.1
format, the sound has already
been recorded in a multichannel
format and is faithfully repro-
duced exactly as the original.

Five dedicated audio channels
(front left, front right, centre,
surround lef t, surround right)
deliver a sound that is as authen -
tic as it is natural. The digital 5.1 surround sound is balanced,
lifelike and crystal clear. It ’s a
sound that ’s as true to a live

performance or cinematic expe -
rience as you can get.
Of course, you can still play
traditional music sources such
as CDs (only format supported
by CDR-30), either in stereo or
in one of the surround modes
generated by patented BOSE®
Centerpoint
® technology. The
algorithm of Centerpoint
® II
extracts a precise and realistic
sound from the stereo signal.
The SurroundStage® signal
processing circuitry developed
by BOSE
® assigns each indi -
vidual audio channel, whether
sourced from a DVD or generated
by Centerpoint®, to a selected
combination of loudspeakers
and is therefore able to deliver
an optimally balanced surround
sound experience to both seat
positions.
To complement these features,
the BOSE
® Surround Sound
System offers a comprehensive
selection of equaliser presets for
customised sound. The dynamic loudness function increases

bass levels as you decrease the
volume, thereby compensating
for the decreasing sensitivit y of
the human ear at these frequen -
cies. Moreover, the AudioPilot
®
Noise Compensation Technology
uses a microphone to continu -
ously measure the ambient noise
inside the vehicle and adapts
music playback automatically so
that a consistent sound is main -
tained in all driving conditions.
The BOSE
® Surround Sound
System. A genuine – perhaps the
only – alternative to the charac -
teristic engine sound.

In an era of intensif ying debate
about CO
2 emissions, every auto -
motive manufacturer is asking
itself what it has to of fer in terms
of environmental protection. Our
answer has long been the same:
maximum efficiency.
Over the last 15 years, Porsche
has been reducing the CO
2 emis -
sions of its vehicles annually by
an average of 1.7 %. In relation to
power output (g / km per hp), Porsche is already among those
manufacturers achieving the

lowest CO
2 emissions. This has
been achieved through the new
efficient drive concept (DFI), light-
weight construction, optimum
aerodynamics and low rolling
resistance.
This high level of environmental
responsibilit y is clearly demon -
st rated by our approach to env iron -
mental management at the
Our contribution to a cleaner environment:
pure engineering.
Porsche development centre in
Weissach. Here, all technological
developments are carried out
with environmental protection in
mind. The goal? Pure perform -
ance – but not at the expense of
the environment. A goal achieved
by the Boxster models.
Exhaust emission control.
Both engines comply with strin -
gent emission standards, including
Euro 5 in Europe and LEV II / ULEV
in the USA. Vehicles manufactured

by Porsche demonstrate that
even high-performance sportscars
can achieve very low emission
values in their respective category.
In short, the Boxster is not only
extremely sport y, it is also very
clean.
This is achieved by means of a
t wo -stage cascade-t ype cataly tic
converter which comprises t wo
monolith substrates on each of the
t win exhaust tracts. These spe -
cially coated substrates contain
ultra-fine honeycomb channels
in which pollutants are converted
as exhaust gas passes through.
The stereo lambda control cir -
cuitry controls and monitors each
cylinder bank separately, while
another lambda sensor on each
cylinder bank monitors pollutant
conversion in the respective cata -
ly tic converter (p. 38).*

Fuel economy and recycling.
At Porsche, a fundamental aspect
of design is intelligent light weight
construction. For both economical

and ecological reasons. This
forms the basis for low fuel con -
sumption values in conjunction
with out-standing performance.
It is economical thanks to the
high proportion of aluminium cast
alloys, plastics and super high-
strength sheet steel used. This is
substantially lighter and more
stable than conventional steel.

Boxster | Environment
Boxster S
In the Boxster models approxi -
mately 20 % of components are
made from light weight alloys.
We use only innovative and envi -
ronmentally friendly components,
and each material is labelled
to facilitate its separation for
recycling. Recycled plastics are
used where they meet exacting
technical requirements. In all,
the Boxster models are approxi -
mately 95 % recyclable.

In addition, Porsche uses only
environmentally friendly water-
based paints. The Boxster models
are absolutely free of asbestos,
CFCs and components manufac -
t
ured using CFCs. This is because,
here at Porsche, 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 already
designed to operate on fuels
with an ethanol content of up to
10 %. Ethanol has a positive
impact on the CO2 balance since
the plants cultivated for the
production of this biofuel also
absorb CO2 from the atmosphere.

The release of hydrocarbons
from the fuel system has been
minimised thanks to the active
carbon filter and a special coating
on the fuel tank. All fuel lines
are made of aluminium and multi-
layered plastic.
.
Noise.
The Boxster models comply
with all applicable noise regula -
tions without any form of engine
encapsulation. To achieve this,
noises are eliminated at source.
Engine parts are stif f, moving
parts are light weight and toler-
ances are kept to a minimum.
Large-volume silencers and reso -
nators in the air intake system
minimise noise further. For the
entire service life of the vehicle.
Maintenance.
Long service intervals offer
clear advantages. For you: lower
costs and saved time. For the
environment: the use of fewer
consuables and replacement
parts. For full details of service
intervals, please refer to the
separate price list.
