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.

Boxster and Boxster S
Lightweight construction.
Both Boxster models are equipped
with alloy engines. Ingenious
design down to the finest detail
has enabled weight – and conse-
quently fuel consumption – to be
reduced. Integrating the camshaf t
bearings fully into the cylinder
heads is just one example of the
ef fective light weight construction
measures that have been imple -
mented.
Integrated dry-sump lubrication.
Integrated dry-sump lubrication
guarantees a reliable oil supply
while reducing engine tempera -
tures, even in sportily driven cars.

The oil reservoir is located inside
the engine. Four oil pumps trans -
port the oil from the cylinder heads

directly into the oil sump. A fif th
pump in the oil sump directly sup -plies the lubricating points in the
engine. To reduce power losses
and increase efficiency, an elec
-
tronically controlled oil pump
supplies the engine lubrication
points as and when required.

This means that the oil pump does
not work so hard when there is
less demand for lubrication. The
benefits of an on-demand oil
supply system are optimum effi -
ciency combined with a reduction in both fuel consumption and

CO
2 em issio ns.

For the engine, these detailed
solutions mean a consistent

oil supply, regardless of gravita -
tional loads, even in the most
demanding track conditions.
Engine cooling system.
Our cross-flow cooling system,
as used in motorsport, supplies
each cylinder uniformly with cool -
ant. Valves are thus protected
against overload and premature
wear, which minimises the
engine’s tendency to knock and
reduces emissions, fuel con -
sumption and engine noise.

Under oil pressure, clutch 1
closes and forms a frictional
connection with input shaf t 1.
The torque is now transmit ted
through the first half gearbox
– and then the dif ferential – to
the rear axle. At this stage,
PDK has already preselected
the next gear in the second
half gearbox. Engine torque
is already acting on the other
outer disc carrier and, in
response to a gear change
signal, the overlap shift is initi -
ated, i.e. as clutch 1 opens,

clutch 2 closes. The non-positive
connection with input shaft 2
is
established, and power is
trans
mit ted to the wheels.
The gear which is engaged is
displayed on the instrument
cluster.
Depending on the gearshift
programme, the gear change
is optimised for comfort or for
sport y handling and takes place
in a mat ter of milliseconds.

The advantage over a fully manual
transmission is the considerably
faster rate of acceleration for the
same rate of fuel consumption.
Boxster | Drive
The advantage over a fully auto -
matic transmission
is the per -
ceptible increase in driving
dynamics – with a similar level of
comfort, and a distinct reduction
in fuel consumption.
The com -
pact dimensions of the gearbox
reduce rotational
masses which
means a more direct engine
response, and the system is
more lightweight.
PDK function diagram
This, along with the long-ratio
7th gear, helps to achieve
reduced fuel consumption and
emission figures comparable with
those of a manual gearbox.
With the optional Sport Chrono
Package, PDK is enhanced by
the
‘Launch Control’ and ‘motor-
sport- derived gearshif t strategy’
functions (p. 57). In essence, PDK combines sport
i
-
ness with efficiency and comfort.

Suspension.
The suspension of the Boxster
models has been tuned to match
the high performance of the
engines.
Light weight coil- over McPherson
struts are combined with lateral
control arms to ensure excellent
driving dynamics and safet y on
all road surfaces. The axle kine-matics are designed for high
performance, as is the generous
wheel track. Light weight con
-
struction throughout keeps the
overall weight and unsprung
masses low, with almost all mov -
ing parts made from aluminium.
The mid-engine design, in com -
bination with the complex chassis
technology, results in minimum
roll and pitch movements on
cornering, braking and accel -
eration.
The chassis of the Boxster
models ensures high safet y
reserves irrespective of load,
and easily controllable load
transfer when cornering. Corner -
ing stabilit y is exemplary, even
in high-speed bends. The same
applies to straight-line stabilit y.
Steering.
What use is a perfect suspension
setup without perfectly tuned
steering? For Porsche, this would
be inconceivable. The solution
is a steering system which is as
precise and immediate as the
chassis itself and, thanks to the
power assistance, steering ef fort
is reduced to a comfortable
level. Around the straight-ahead
position, such as during motor -
way driving, the ratio is less
direct but with no loss of agilit y
or feedback.
Boxster | Chassis
The greater the steering angle,
the more direct the steering
ratio. This is particularly notice-
able when turning tight corners
or parking. The car has a turning
circle of just 11.1 m.

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.
