The optional Porsche Doppel-
kupplung (PDK), with both man -
ual gearshift and an automatic
mode, enables smooth gear
changes with no interruption in
the flow of power. This results

in significantly faster acceleration
and lower fuel consumption, without having to sacrifice the
ease of automatic transmission.
In total, PDK has seven gears at
its disposal. Gears 1 to 6 have a
sports ratio and top speed is
reached in 6th gear. The 7th gear
has a long ratio and helps to

reduce fuel consumption even
f u rt h e r.
PDK is essentially t wo half gear-
boxes in one and thus requires
t wo clutches – designed as a
double wet clutch transmission.
This double clutch provides an
alternating, non-positive connec -
tion bet ween the t wo half gear -
boxes and the engine by means
of t wo separate input shafts
(input shaft 1 is nested inside the
hollowed-out input shaft 2).
The flow of power from the
engine is only ever transmit ted
through one half gearbox and
one clutch at a time, while the
next gear is preselected in the second half gearbox. During a
gear change, therefore, a con
-
ventional shif t no longer takes
place. Instead, one clutch simply
opens and the other closes at
the same time. Gear changes
can therefore take place within
milliseconds.
Clutch 1 controls the first half
gearbox, which contains the odd
gears (1, 3, 5, 7) and reverse.
Clutch 2 controls the second,

which contains the even gears
(2, 4, 6).

The crankshaf t transmits engine
torque to the dual-mass fly wheel
which is then channelled through
the clutch housing and onto the
multi-plate clutches, or to be more
precise, the outer disc carrier.

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.

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 | Safet y
Passive safety: engineered
design.
The deformation zone at the
front of the vehicle contains a
system of longitudinal and lateral
members which absorb the
energy in the event of an impact.
The fuel tank and fuel lines are
safely positioned outside the
deformation zone. Together with
the rigid side structures, high-
strength steel elements in the
doors provide exceptional side-
impact protection. The reinforced
windscreen frame and the roll-
over bars positioned behind the
seats provide an ef fective barrier
if the car overturns. Energy-
absorbing materials are used at
key points throughout the passen -
ger compartment.
Both Boxster models are fit ted
as
standard with an airbag system

comprising t wo full-size front air -
bags as well as dedicated head
and thorax airbags (POSIP, p. 67)
on each side. This arrangement
ensures optimum upper-body

protection, even when the hood is
open. For added comfort and
safet y, the three-point belts have
integrated force limiters and
pretensioners.
Roll-over protection.
The front area of the cockpit is
protected by a robust steel
element integrated invisibly into
the windscreen frame. The rear
roll-over bars are made from high-
strength steel and are located
behind the seats. Their flat tened
form ensures high safet y, and
harmoniously follows the lines of
the seat backrests. The upper
seat-belt anchorage points are
at tached to the bars for greater
accessibility and comfort.
Porsche Side Impact
Protection (POSIP).
Both Boxster models are equipped
with Porsche Side Impact
Protection (POSIP) as standard.
This consists of t wo airbags on
each side. The outer bolsters of
the seats contain a thorax air-

bag and each door contains a head
airbag. Each has a volume of
around 8 litres, ensuring high
protection in the event of a side
impact, even when the hood is
open. The passenger cell is also
shielded by side impact protec -
tion beams in the doors.
Child seats.*
For our youngest Boxster pas-
sengers, the Porsche Tequipment
range of accessories includes
child seats and the necessary
preparation. This comprises an
ISOFIX fixing bracket for mount -
ing the Porsche child seats, and
a key switch to deactivate the
passenger airbag.

Instruments.
Each black circular dial in the
instrument cluster – aluminium-
coloured in the Boxster S –
provides important information
at a glance. In the centre is the
analogue rev counter with digital
speedometer and a customis - able display of key data from the
standard on -board computer.
Additional data, such as average
fuel consumption, fuel range or
the data of the optional TPM can
be shown as desired.
The right-hand dial displays the
outside temperature and shif t
pat tern of the optional Porsche
Doppelkupplung (PDK), as well

as the selected gear. The dial on
the lef t contains the analogue
speedometer with digital trip
meter and total distance display.
The design and legibilit y of the
dials are also enhanced by the
white backlight illumination.
Steering wheels.
The Boxster models are equipped
as standard with a three -spoke
sports steering wheel with full- size
airbag. As an option, you can
specify a three-spoke multifunction
steering wheel with integrated
but tons for the most essential
audio and, where applicable, navi -
gation and telephone functions. The multifunction steering wheel

is available in a choice of smooth
leather, Aluminium Look, carbon
or macassar finish.

· 92 ·· 93 ·
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.
