The standard Porsche Stabilit y
Management (PSM, p. 63) further
enhances active safet y with its
brake assist feature and a pre-
charging function which increases
braking system readiness.

The design of the Boxster models
is governed by one philosophy
above all: that the st yling of a

Porsche reflects its inner values.
Here, the primary value is extreme
performance.
In the interior, the elegant sports
st yling is coupled with a high
degree of practicalit y. All the
important functions are intuitive
to control, including the optional
Porsche Communication Manage -
ment (PCM, p. 83) with 6.5-inch
touchscreen and CD/ DVD drive
with navigation module.
In conjunction with the PCM, the
optional BOSE
® Surround Sound
System supports 5.1 surround
sound.

A rhetorical question: What would
you do if we were to give you
the key now?
A real roadster is like true love:
you recognise it at first glance.
Design.
This concept also follows a
traditional Porsche theme: the
seamless blend of function
and design. Visually exciting
with performance to match.
The emphasis on high perform -
ance is immediately evident
from the front, where large air
intakes in a powerful geometric
design lend both Boxster models
a dynamic look – and increase
cooling power. On the Boxster,
the air intake grilles are finished
in the exterior colour, whereas
on the Boxster S they are con-
trasted in sporting black. The
athletic
appearance is comple -
mented by
striking spoiler lips.
The t wo models have a drag
coefficient
value of 0.29 and
0.30, respectively.
At the front, the headlight design
makes the Boxster models unmis
-
takable – especially at night.
The Boxster models are fit ted as
standard with halogen headlights
and LED day time running lights
integrated separately into the clus-
ters above the outer air intakes.
Bi-Xenon headlights with dynamic
cornering lights, including LED
day time running lights, are avail -
able on request. The dynamic
headlight design emphasises the
striking contour of the wing.

The rear features LED taillight
modules that blend harmoniously
with the overall design. The
centrally located stainless steel
tailpipe – t win tailpipes on the
Boxster S – and the rear diffusers
finished in sporting black com -
plete the powerful look. The
dynamic presence of the Boxster
models is further emphasised
by the clean, neat design of the
wheels. The Boxster is fit ted with
17-inch wheels as standard, the
Boxster S with 18-inch wheels.
A 19-inch option is available for
both models.
In short, although we rarely stick
to the rules, we have observed
one: form follows function. Design
and functionalit y are combined
perfectly in the Boxster models.

Engine management system
with electronic throttle.
The electronic engine manage -
ment system ensures optimum
engine performance under all
operating conditions. It regulates
all engine-related functions and
assemblies (see diagram). The
results: optimum performance
and torque with reduced fuel con -
sumption and emissions.
Another important function of the
system is cylinder-specific knock
control. Since the six cylinders
never all work under precisely
the same conditions, they are
monitored individually by the
knock control. If necessary, the
ignition point is shifted individu -
ally to protect the cylinders and
pistons at high engine speeds
and loads. The on-board diagnos -
tics, which are compliant with
European standards, ensure
timely detection of any faults and
defects that may occur in the
exhaust and fuel system in good
time and notify the driver
immediately. This also prevents
increased pollutant emissions
and
unnecessary fuel consumption.
Two-stage resonance intake
manifold.
The intake manifold with dual-flow
distributor pipe has an adjustment
valve which closes and opens at
set engine speeds. A t wo -stage
tuning effect creates oscillation
of the air mass in the intake

system, which in turn generates
a turbocharging effect and opti -
mises induction.
These t wo effects combine to
produce higher torque at low
engine speeds, a flat ter torque
curve, and increased power
output at high engine speeds.
The acoustic properties of the
system are second to none,
producing the characteristic
Boxster sound.

For an even sportier drive, PSM
can be deactivated. However,
it is automatically reactivated for
your safet y if either of the front
wheels (in ‘Sport ’ mode, both of
the front wheels) requires ABS
assistance. ABD remains perma -
nently active.
PSM includes t wo additional func -
tions: precharging of the brake
system, and brake assist. If you
suddenly release the accelerator
pedal, PSM automatically readies
the braking system. With the
braking system having been
precharged, the brake pads are
already in light contact with the
brake discs. Maximum braking
power is therefore achieved
much sooner. When sudden brak -
ing is detected, the brake assist
function applies maximum brake
pressure to all four wheels.
Lights.
The Boxster models are all fit ted
with halogen headlights with
LED position lights integrated
separately into the front light unit
with integral fog lights above the
outer air intakes.
LED technology is also used in
the taillight unit to provide bet ter
illumination and respond more
quickly to driver input. Further
benefits are that LED bulbs are
energy saving and have a longer
life than conventional bulbs.

The design is unmistakable, both
day and night.
Bi-Xenon headlights with
dynamic cornering lights and
LED daytime running lights.
Available as an option for both
Boxster models are Bi-Xenon
headlights which include dynamic
cornering lights and LED day time
running lights.
Bi-Xenon headlights are brighter
than halogen headlights so that
they of fer improved visibilit y and
they illuminate the road more evenly. In fact, they are so effec
-
tive that separate fog lights are
no longer necessary. A headlight
cleaning system is built-in.
Dynamic cornering lights of fer
particularly effective illumination
of the road ahead, especially
through bends. Sensors continu -
ously monitor the speed, lateral
acceleration and steering lock
and, from these variables, calcu -
late the course of the bend.
This determines the angle
of the dynamic cornering lights,
with the lights able to swivel
into the corners up to a limit of
15 degrees, even with main
beam switched on.
