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.

Boxster
Boxster
You can tell a good concept from
t he fact t hat i t isn’t just short- term.
We appear to have got something
right.
Because the basic concept
of the Boxster has lost none of its
appeal in over 60 years. Even though the gap bet ween the
Porsche 356 No.1, the 550 Spyder
and the Boxster seems huge, it ’s
still an out-and-out roadster. High

performance, lightweight con
-
struction, sporting agility, pure
driving pleasure – these values
are reflected in every detail.
Many fairytales begin with ‘Once upon a time’.
But only a few true stories do.
The Boxster.
The 2.9-litre six-cylinder Boxer
engine delivers a power output
of 188 kW (255 hp) at 6,400 rpm
and a maximum torque of 290 Nm
at bet ween 4,400 and 6,000 rpm.
The six-speed manual gearbox
has been optimally matched to
the engine characteristics
and high power output. From a
standing start, the Boxster accel-
erates to 100 km/ h (62 mph) in
5.9 seconds. Or just 5.8 seconds
with the optional Porsche Doppel -
kupplung (PDK, p. 42). And com -
plementing this perfectly is the
sporty, lightweight chassis.
Integrated centrally below the
rear panel is a stainless steel tail -
pipe which produces the distinc -
tive Boxster sound.
The 17-inch Boxster III wheels
with an open five-spoke design
allow a clear view of the brake
system with its black anodised
four-piston aluminium monobloc
fixed calipers. The large front
and rear brake discs ensure excel -
lent braking performance.

Adding further to the st ylish
design of the Boxster are the
front air intake grilles finished
in the exterior colour.
The Boxster. A roadster that
stirs emotions. Because it
doesn’t just reflect the passion
of our engineers, but over half
a century of Porsche history.

The flagship model in the Boxster
range has also evolved: the
Boxster S. It presents an even
more athletic interpretation
of the roadster concept. More
powerful and more ef ficient. Its
engine is fit ted with direct fuel
injection (DFI, p. 28) as standard. For increased torque and power
– with a simultaneous reduction
in fuel consumption. The result is
228 kW (310 hp) at 6,400 rpm
and a maximum torque of 360 Nm
at 4,400 –5,500 rpm. It acceler -
ates from 0 to 100 km/ h (62 mph)
in just 5.3 seconds. With the
optional Porsche Doppelkupplung
Like a shot of adrenalin.
Intravenously.
The Boxster S.
(PDK, p. 42) and ‘Launch Control’
from the optional Sport Chrono
Package, just 5 seconds. Com-
pared with the previous model,
fuel consumption has been
reduced by up to 15 % depending
on the t ype of gearbox fit ted,
and CO2 emissions by up to 16 %.

As well as the 18-inch Boxster S II
wheels in a dynamic design, the
Boxster S is fit ted with a power -
ful braking system which is
distinguished by its red-painted
calipers. The rear brake discs
are thicker than those on the
Boxster for increased stabilit y
under braking. The front air intake grilles are
painted black for a striking con
-
trast. Together with the centrally
mounted t win tailpipe, they give
the car a powerful presence.

In the interior, as well as leather
on the steering wheel, PDK selec -
tor/gear lever, handbrake lever
and door handle, the Boxster S
has leather trim on the storage
compartment covers in the door
and the rear centre console. The
instrument dials are aluminium -
coloured.

These are just the facts. To expe
-
rience the performance of the
Boxster S, we can only of fer one
piece of advice: you really need
to drive it.

Three-spoke sports steering
wheel with gearshift switches.
In conjunction with the optional
Porsche Doppelkupplung (PDK),
the standard three-spoke sports
steering wheel features t wo
ergonomic switches. One press
with the thumb and the PDK
shif ts up. One pull with the index
finger and the PDK shif ts down.
Either the right or left hand can
be used.
When combined with the optional
Sport Chrono Packages (p. 56),
an additional display is located
above the airbag module telling you whether the SPORT, SPORT
PLUS and Launch Control func
-
tions are activated.
Three-spoke sports steering
wheel with gearshift paddles.
If you wish, you can now change
gear motorsport-st yle. The
paddles are made from a strong
alloy and are ergonomically
located behind the steering wheel
spokes. Pull the right-hand paddle
and the PDK shif ts up. Pull the
left-hand paddle and the PDK
shifts down.
Visually, the steering wheel is
distinguished by its distinctive,
high - qualit y t win -spoke design
and silver-coloured galvanised
spoke cover. The airbag module
is finished in the same colour
as the steering wheel rim.
Displays in the left and right-
hand steering wheel spokes tell
you whether the SPORT, SPORT
PLUS and Launch Control func -
tions are activated. Another

feature reminiscent of the world
of motorsport is the top centre
marking on the steering wheel
rim.

Gear selector for PDK.
The gear selector for PDK im-
presses not only with its unique
design, but above all with its
superior functionality enabling
you to change gear manually.

Press forwards to shift up, pull
backwards to shift down. Even if
the gear selector is set to auto -
matic mode, you can still change
gear manually using the switches
on the steering wheel.
Six-speed manual gearbox.
Fit ted as standard is a six-speed
manual gearbox which is per -
fectly matched to the character -
istics of the engine. The shif t
throw is short and precise, the
tuning is sport y – as befits the
character of the Boxster models.
The dual-mass fly wheel mini -
mises engine noise and the con -
trol cable mechanism prevents
vibrations from being transmit ted
to the gear lever.

Hill-start assist.
Standard for manual and Porsche
Doppelkupplung (PDK) transmis-
sions it assists the driver in
making a comfortable, smooth
and roll-free start on an incline.
The system detects you have
braked to a halt on an incline.

Provided a gear is engaged, the
brake pressure is maintained
approximately t wo seconds once
the footbrake is released. The
vehicle is therefore temporarily
prevented from rolling backwards.
Brake pressure is reduced if
sufficient revs have been gener -
ated depressing the accelerator
pedal (for manual transmission,
the accelerator pedal is de-
pressed and the clutch engaged).

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.

Active safety.
Uncompromising sports per-
formance. Comprehensive safet y.
At Porsche, these qualities have

always been inextricably linked.
Just as in the Boxster models
where the body, chassis and
brakes constitute a single inte -
grated system with generous
safety reserves.
The chassis setup allows for an
extremely sport y driving st yle
with exceptional cornering control.
The variable ratio steering is
direct and precise with excellent
feedback from the road.

The braking system ensures
maximum deceleration and

stabilit y. A high power-to -weight
ratio and responsive throt tle
enable easier overtaking and
evasive manoeuvres. Porsche
Stabilit y Management (PSM,

p. 63) fit ted as standard helps
to stabilise the vehicle in critical
driving scenarios, even in
unfavourable weather conditions.
Also contributing to active
safet y is the ef fective headlight
concept which guarantees
excellent vision at night (p. 64).
Boxster | Safet y
Braking system.
The Boxster and Boxster S have
a braking system with four-
piston aluminium monobloc brake
calipers fit ted front and rear.
Offering excellent rigidit y, they
are compact and save on weight.
Their superior responsiveness,
for fast and sensitive braking, sets
them apart.
A brake booster reduces pedal
ef fort whilst maintaining powerful
braking. A special ventilation
system, whereby the entire wheel
brake is cooled through openings
in the front end and special
channelling systems, increases
the stabilit y of the brakes during
heav y use.

Both the Boxster and Boxster S
have internally vented brake
discs at the front with a diameter
of 318 mm, whilst the rear discs
measure 299 mm. The result is
impressive braking performance.
The brake discs on the Boxster S
are 4 mm thicker than those
on the Boxster, which increases
stabilit y even further. To distinguish them visually,

the brake calipers on the Boxster
have a black anodised finish
while those on the Boxster S are
painted red.
For reduced weight, bet ter cool -
ing and optimum braking in the
wet, the brake discs are cross-
drilled.

Porsche Ceramic Composite
Brake (PCCB).
On request, we can equip your
Boxster S with a brake system
that has already had to cope
with the harshest requirements
of motorsport: the Porsche
Ceramic Composite Brake (PCCB).

The ceramic brake discs have
a diameter of 350 mm front and
rear – for extremely powerful
braking. The brake discs are
formed from a specially treated
carbon -fibre compound that is
silicated in a high-vacuum process
at approximately 1,700 ˚C. Not
only are the resulting discs much
harder than standard discs, they are more resistant to heat.
The low thermal expansion of

the brake discs prevents defor -
mation under heav y braking.
Furthermore, the ceramic brake
discs are totally resistant to
corrosion and offer more favour -
able noise-damping properties.

Six-piston aluminium monobloc
fixed calipers on the front axle
and four-piston units at the rear
provide a high and constant
brake pressure. The pedal
response is fast and precise with
only moderate input required.
All the necessary ingredients
are there for a short braking
distance, even in the toughest
conditions. Moreover, safet y
under braking at high speeds is
increased thanks to the excel-
lent fade resistance of PCCB.
The key advantage of PCCB
is that the brake discs are
approximately 50 % lighter than
standard discs of similar design
and size. A factor that helps
to reduce unsprung and rotating
masses on the vehicle. 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 signifi -
cantly reduce the service life of
even the most durable brake
pads and discs. We recommend
that all brake components be
professionally inspected and
replaced where necessary after
every track event.
Porsche Stability Management
(PSM).
PSM, which comes as standard,
is an automatic control system
that stabilises the vehicle at the
limits of dynamic driving per-
formance. Sensors continuously
monitor driving direction, speed,
yaw velocit y and lateral accel -
eration. Using this information,
PSM computes the actual direc -
tion of motion. If this direction
deviates from the desired course,
PSM initiates braking inter-
ventions targeted at individual
wheels in order to stabilise the
vehicle.

Under acceleration on wet or
low-grip road surfaces, PSM
improves traction using the ABD
(automatic brake differential)
and ASR (anti-slip regulation)
functions, giving an agile
response. When ‘Sport ’ mode is
selected on the optional Sport
Chrono Packages (p. 56), the
PSM intervention threshold is
raised to enable greater driver
involvement – particularly at
speeds of up to approximately

70 km/ h (45 mph). The integral
ABS can further reduce the
braking distance.
