Boxster S
Boxster in Porsche Racing Green Metallic
An extraordinarily powerful mid-
mounted engine. An extremely
low centre of gravit y. Very high
agilit y and dynamic handling.

The driving experience offered
by a Boxster goes far beyond
superficial driving pleasure. That ’s
because it ’s based on a concept
which made the 550 Spyder one
of the most successful racing
cars of its time. We see it as the
very embodiment of Porsche
Intelligent Performance.
Both models are powered by
sophis ticated engines. The

Boxster’s six- cylinder Boxer engine,
fit ted with VarioCam Plus (p. 36),
has a 2.9 -litre capacit y, 188 kW
(255 hp) and maximum torque of
290 Nm at 4,400 to 6,000 rpm.
Taking it to 100 km/ h (62 mph)
in just 5.9 seconds, with a top
speed of 263 km/ h (163 mph). Despite this increase in power,
the CO
2 emissions have been
reduced by up to 12
% compared
with the previous model. In com -
bination with the optional Porsche
Doppel kupplung (PDK), the
result is a very low emissions
value of 214 g / km and fuel
consumption of 9.1 l/100 km
(31 m pg ).
The Boxster S has an additional
power boost, with direct fuel injec -
tion (DFI, p. 28) fit ted as standard.
This provides optimum fuel mix-
ture formation for improved fuel
ef ficiency and a distinct increase
in power and torque. In combi-
nation with the optional PDK, this
gives a reduction in fuel con-
sumption of 15 % and lowers CO2
emissions by 16 % compared with
the previous model.
The pleasure of a roadster.
The excitement of a Porsche.
The Boxster models.
The 3.4-litre six- cylinder Boxer
engine in the Boxster S develops
an impressive 228 kW (310 hp).
Maximum torque of 360 Nm is
reached bet ween 4,400 and
5,500 rpm and acceleration to
100 km/ h (62 mph) takes just
5.3 seconds.

In summary, an engine which
is responsive enough to provide
power from the outset – and
reaches its limit at 274 km/ h
(170 mph).

In both models, a precision six-
speed manual gearbox makes
optimum use of the power and
torque of the engine. Available
as an option is Porsche Doppel-
kupplung (PDK, p. 42) featuring
both manual and automatic
modes.
The principle is as impressive
as it is simple: it has seven
gears, t wo half gearboxes and
t wo clutches. As one gear is
engaged, the next is already
preselected in the other half
gearbox.
Gear changes take place in milli
-
seconds without any interruption
in the flow of power. The advan -
tage over a fully manual trans
mis -
sion is the considerably faster

rate of acceleration for the same
level of fuel consumption. The
advantage over a fully automatic
transmission is a perceptible
increase in driving dynamics –
with a similar level of comfort
and a distinct reduction in fuel
consumption. In short, Porsche
Doppelkupplung (PDK) not only increases the agilit y of the

Boxster but also enhances
driving pleasure.
As you would expect, the chas-
sis setup ensures a supremely
sport y ride. A wider track and
generously dimensioned wheels
in a dynamic design provide an
even sportier driving experience.
The optional mechanically locking
rear dif ferential (p. 54) delivers
high traction and increased per -
formance.
When fit ted in combination with
PDK, the optional Sport Chrono
Package (p. 56) gives you access

to t wo further functions: ‘Launch
Control’ for maximum accelera -
tion from a standing start, and
a ‘motorsport-derived gearshift
strategy’, bringing gearshift
characteristics straight from the
racetrack.

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.
VarioCam Plus (see p. 36) in
conjunction with the resonance
intake manifold ensures high
torque even at low speeds, and
excellent power development
in the upper rev range. Maximum
torque is available over a wide
rev range, reaching 290 Nm
bet ween 4,400 and 6,000 rpm.
The engine in the Boxster S fea -
tures direct fuel injection (DFI)
and delivers a power output of
228 kW (310 hp). The 3.4 - litre
power plant develops a maxi-
mum torque of 360 Nm bet ween
4,400 and 5,500 rpm.

For incredible driving perform -
ance and higher torque, espe-
cially in the lower rev range, with

VarioCam Plus.
VarioCam Plus combines variable
valve timing with t wo -stage lift
on the inlet side. This results in
smoother running, bet ter fuel
economy and lower exhaust emis-
sions. As well as greater top - end
power and low-end torque.
This two-in-one engine concept
seamlessly adapts in response to
driver input. The result: instant
acceleration and extremely smooth
running.

The variation in intake timing is
steplessly controlled by means of
an electro -hydraulic rotary vane adjuster at the head of the corre
-
sponding camshaft.To improve throt tle response
during the warm-up phase, Vario -
Cam Plus selects high valve lifts
with retarded valve timing. In the
middle and low load ranges, low
valve lifts with advanced timing
Boxster | Drive
reduce fuel consumption and
exhaust emissions. High valve
lifts generate high torques and
maximum output.
VarioCam Plus Boxster S and Boxster
Ignition system.
The ignition system in the Boxster
models is designed for high-
voltage static distribution. The
individual ignition coils, located
on the spark plugs for optimum
ignition reliabilit y, are controlled
directly by the engine electronics.

· 38 ·· 39 ·
Exhaust system.
The exhaust system – with t win
tailpipes on the Boxster S – is
made of stainless steel. Until it
converges in the connecting tube,
the exhaust gas is channelled
through t wo separate tracts and,
thanks to separate exhaust gas cleaning systems, the exhaust
gas can flow more freely – for
increased power and torque.
The stereo lambda control

circuitry controls and monitors
each cylinder bank separately.
For each exhaust tract, four
corresponding oxygen sensors regulate the composition of the
exhaust gas and monitor the con
-
version of pollutants in the cata -
ly tic converters.
A sports exhaust system – for a
more resonant sound – is avail -
able as an option for each of the
Boxster models.
Boxster | Drive
Servicing.
Every Porsche is designed with
durabilit y in mind. On the Boxster
models, this is reflected in the
lengthy service intervals. The alternator, power steering
pump and the air- conditioning
compressor are all driven by a
single self-adjusting belt. The
drive chains on the camshafts
and intermediate shaf ts do not
normally require servicing. With the sole exception of the
spark plugs, the ignition system
is also maintenance-free.
So your Boxster remains where
it belongs for as long as possible:
on the road.

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.
