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.

Boxster and Boxster S
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.

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.

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.

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.

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.
