Engine
For fuel consumption and CO2 emissions please refer to page 127.
The engine will restart as soon as you
operate the clutch or, in cars with PDK,
release the brake. This fuel-saving inno -
vation is designed primarily for use in
towns or congested motorway traffic.
The auto start /stop function can be
deactivated and reactivated using a sepa -
rate but ton on the centre console. The
function may be deactivated automatically
under particular circumstances, e.g. in
extreme outside temperatures, when the
SPORT but ton is selected or when there
is low bat tery charge.

Cruise control.
This optional automatic speed controller
for the 19 to 149 mph (30 to 240 km/ h)
speed range is operated using a switch
on a separate control stalk on the steering
column. The advantages are claer, not
only can cruise control be used as a
means of staying within the speed limit,
it also helps you to save fuel by maintain -
ing a constant speed.
Electrical system recuperation.
For enhanced efficiency the new Boxster
models are equipped with intelligent elec-
trical system recuperation. The vehicle
bat tery is recharged by the generator
predominantly under braking. Thanks to this selective recharging, when you
request full driving power the maximum
possible output can be directed straight
to the road.
Servicing.
In the Boxster models, the generator and
air conditioning system are driven by a
single self-adjusting belt. The drive chains
on the camshafts do not normally require
servicing. With the sole exception of the
spark plugs, the ignition system is also
maintenance-free in normal servicing. In
short, longer service intervals mean longer-
lasting driving pleasure.

Six-speed manual gearbox.
The new Boxster models are equipped
as standard with a light weight six-speed
manual gearbox. Gearshifts are smooth
and optimally adapted to the respective
engine map. Shift throws are short and
sport y and the gear lever is easy to oper -
ate, enabling a rapid gearshift action and
providing a truly engaging driving experi -
ence. The upshift indicator located in the
central circular instrument helps you to
maximise fuel efficiency.
The elevated centre console gives you an
authentic sports car feel. It positions the
gear lever close to the steering wheel, which enables you to change gear as fast
and as ergonomically as possible.
Porsche Doppelkupplung (PDK).
Available as an option for the new Boxster
models is a completely retuned 7-speed
Porsche Doppelkupplung (PDK), featuring
both manual and automatic modes. PDK
offers extremely fast gear changes with no
interruption in the flow of power, improved
acceleration over the manual gearbox, very
short response times, reduced fuel con
-
sumption and a distinct increase in comfort.
In total, PDK has seven forward gears at its
disposal. Gears 1 to 6 have a sports ratio

Transmission.
and top speed is reached in 6th gear. The
7th gear ratio is longer and keeps engine
speed low to improve ride comfort and
reduce fuel consumption at higher speeds.
The design of PDK is similar to t wo
conventional gearboxes in one. The odd
numbered gears are housed on one
assembly and the even numbered gears
on another, each having its own clutch.
While one gear is engaged, PDK pre-
selects the next gear based on driver
input. When the next gear is requested,
drive is switched from one clutch to
the other in milliseconds, delivering gear
changes with no loss of drive.

Coasting.
The coasting function available with
Porsche Doppelkupplung (PDK) enables
you to save even more fuel where the
situation allows. The engine is decoupled
from the transmission to prevent
deceleration caused by engine braking.
In this way, optimum use is made of
the vehicle’s momentum, allowing it to
coast for longer distances.
For example, you may want to slow down
from 60 mph to 40 mph in anticipation
of the change of speed limit ahead. As
you ease off the accelerator pedal, PDK
deselects the current gear automatically
and you begin to coast in neutral until
you have reached your desired speed. As
soon as you operate the accelerator or brake pedal, PDK re-engages the appro
-
priate gear within fractions of a second.
The process is smooth and seamless
thanks to the extremely fast clutch.
Another way to reduce fuel consumption
is to utilise the coasting function on
downhill gradients that are gentle enough
for you to maintain a constant speed.
Efficient on long journeys, such as on the
motorway, PDK remains ready to respond
as swiftly and precisely as you would
expect.
In short, driving in coasting mode makes
a real impact on fuel consumption with -
out any need for compromise on comfort
or sporty performance.
With the SPORT but ton selected, the full
advantages of the new version of PDK
are brought into play: a more immediate
response to throt tle inputs, even shorter
shift times and swift, throttle-blip down -
shifts on overrun and when braking –
always accompanied by an emotive engine
sound.
With the optional Sport Chrono Package,
PDK is enhanced by the ‘Launch Control’
and ‘motorsport- derived gearshif t strategy’
functions (p. 63) for even faster gear
changes and the best possible per formance
thanks to a boost in torque during upshift
phases. Overrun downshifts provide
extremely sport y braking and acceleration
for added excitement.

Even when you want to make a break
from everyday life, you should still keep
your feet on the ground.
The chassis of the new Boxster models
are an excellent match for the powerful
engines. Axle components are made
predominantly of aluminium. This light -
weight material helps to keep the weight
of the vehicle and its unsprung masses
low, which reduces fuel consumption,
improves comfort and increases agility.
The wide track is a prominent feature to
provide additional stability and enhanced
comfort, the wheelbase has been extended
by 60 mm compared with that of the
previous model. The new independent
suspension features lightweight spring-strut
a
xles with longitudinal and transverse links
and, at the front, cross members that
have been refined for optimum control.
As a result, each wheel moves precisely
to ensure excellent directional stability
and superior handling in all situations.
What does this mean for the driver? The
sophisticated engineering of the chassis,
combined with the mid-engined layout,
achieves impressive dynamic performance.
Body roll and pitch have been practically
eliminated to offer a level of agilit y that
turns each corner into an incomparable
experience.
A love of freedom is no reason
to lose self-control.
Chassis.
Porsche Active Suspension
Management (PASM).
Optional PASM, the electronic damping
control system, suits the new Boxster
models down to the ground. PASM
actively and continuously regulates the
damping force for each wheel according
to the
road conditions and driving st yle.
In addition, the suspension is lowered
by 10 mm.
The driver can select bet ween t wo
dif ferent modes: ‘Normal’ which is a
blend of performance and comfort,
and ‘Sport ’ where the setup is much
firmer. Depending on the mode selected,
For ward thrust |
Chassis
therefore, PASM can be both sportier
and more comfortable than the standard
chassis. The PASM control unit evaluates
the driving conditions and modifies the
damping force on each of the wheels in
accordance with the selected mode.
Sensors record the body movements that
accompany powerful acceleration, brak -
ing or uneven road surfaces. This enables
intelligent adaptation of damper stif fness
for the selected mode, optimising contact
bet ween each individual t yre and the road
and reducing pitch.

Chassis
In ‘Sport ’ mode, the suspension is set
to a harder damper rating. On uneven
roads, PASM immediately switches
to a softer rating, thereby improving
contact bet ween the t yres and the
road. When the road surface improves, PASM automatically reverts to the

original, harder rating. If ‘Normal’ mode is
selected and the driver’s st yle becomes
more assertive, PASM switches to a

harder rating to increase driving stability
and road safet y. The results are tangible: increased driving
stability, enhanced driving pleasure and
improved performance.
Steering.
One definition of efficiency is a system

that works only when it is needed, and then
does so in a particularly effective way.
This was the guiding principle for our
engineers in the development of the new
electromechanical steering system.
Whereas a conventional hydraulically
assisted steering system draws engine
power continuously, the electric motor
in the electromechanical arrangement
uses energy only when the steering

wheel is actually turned. As a result, fuel
consumption is reduced and the absence of hydraulic fluid eliminates the need for
servicing, both of which also have benefits
for the environment.
The Boxster concept was designed to of fer
outstanding cornering performance. The
new steering system delivers and it even
improves the typical Porsche steering feel. It features a variable steering ratio and
responds precisely and directly as well as
providing customary agility, a high level of
comfort and plent y of direct feedback from
the road. Power steering Plus, the optional
speed -sensitive power-steering system, mini

mises steering ef fort during manoeuvring
and parking.

Wheels.
The standard wheels on the new Boxster
models have been enlarged by one inch
compared with those of the previous
models. Made from a light weight alloy, the
larger wheels reinforce the car’s imposing
presence and further improve sport y
performance. The new Boxster is equipped with 18-inch
wheels. Their minimalist five-spoke design
is sport y and elegant in equal measure.
Tyre sizes are 235/45 ZR 18 and 265/45
ZR 18 at the front and rear respectively.
The Boxster S has 19-inch wheels with
a dynamic dual-spoke design. The t yre
size at the front is 235/40 ZR 19 and
265/40 ZR 19 at the rear.
The larger rolling circumference improves
comfort and performance. At the same time, the rolling resistance of the new gen
-
eration of t yres has been reduced which,
in turn, helps to reduce fuel consumption.
Wheels up to 20 inches are available as an
option.
Tyre Pressure Monitoring (TPM).
Optional Tyre Pressure Monitoring (TPM)
sends warnings to the on-board comput -
er’s display screen in the event of low t yre

Another key advantage of PCCB is the
extremely low weight of the ceramic
brake discs, which are approximately
50 % lighter than standard discs of similar
design and size. As well as enhancing
performance and fuel economy, this represents a major reduction in unsprung
and rotating masses. 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 significantly reduce the
service life of even the most durable
pads and discs. As with conventional
high-performance braking systems, we recommend that all brake compo
-
nents be professionally inspected and
replaced where necessary after every
track event.
Electric parking brake.
The electric parking brake, which can
be activated and deactivated manually,
is released automatically as you pull
away with your seat belt fastened. A hill
hold function is integrated as standard for the manual gearbox and for PDK.
It assists you in making a comfortable,
smooth and roll-free start on an incline.
Whenever you come to halt on an incline,
this is detected automatically and the
braking effect of the electric parking brake is supplemented by application

of the wheel brakes. As long as a gear
remains engaged, the brake pressure
is maintained at all four wheels. To pull
away, simply apply throttle (manual gearbox: apply throt tle and release the
clutch pedal). The wheel brakes are
released as soon as sufficient starting
torque is available and the parking brake
is released as the vehicle moves off.

If we are to continue to enjoy driving
pleasure, we need to look after our
environment. In other words, we need to
take responsibilit y. In an era of intensify -
ing debate about global climate change
and CO
2 emissions, every automotive
manufacturer is asking itself what it
has to offer in terms of environmental
protection. Our answer has long been
the same: Intelligent Performance –
a combination of high power output and
high efficiency.
In recent years Porsche has managed to
reduce fuel consumption across all model
ranges by a double - digit percentage compared with the respective previous
model, even though performance has
been increased in every generation.

This is made possible by an efficient drive
concept (e.g. direct fuel injection (DFI) and
VarioCam Plus), lightweight construction,
optimised aerodynamics and low rolling
resistance.
The environmental management team
at the Porsche Development Centre in
Weissach aims to demonstrate a high
level of environmental responsibility. Here,
technological developments are carried
out with environmental protection in mind.
The goal is to enhance performance –
You can live for the moment
and still care about tomorrow.
Environment.
but, where possible, not at the expense
of the environment. We achieve this
goal with Intelligent Per formance, as
epitomised by the Boxster.
Exhaust emission control.
Vehicles manufactured by Porsche
demonstrate that even high-performance
sports cars can achieve moderate fuel
consumption and exhaust emission values
in their respective category.
This is achieved, on the one hand, through
the use of fuel - ef ficient technologies such
as auto start /stop, thermal management,
electrical system recuperation, direct fuel

2 emissions please refer to page 127. injection, VarioCam Plus and, in conjunc
-
tion with optional PDK, coasting mode.
On the other hand, newly developed
cataly tic converters provide ef ficient
emission control. While the stereo
Lambda control circuitr y controls and
monitors each cylinder bank separately.
For each exhaust tract, oxygen sensors,
together with the engine electronics
and injectors, regulate the composition
of the exhaust gas, while another
Lambda sensor on each cylinder bank
monitors pollutant conversion in the
respective cataly tic converter.

Fuel economy and recycling.
Intelligent lightweight construction has
been fundamental to the Porsche identit y
since 1948 for both technical and ecolog -
ical reasons. This forms the basis for
achieving low fuel consumption values in
conjunction with outstanding perfor -
mance. On the technical side, various compo
-
nents are made with a high proportion of
aluminium, magnesium, plastics and
super- high -strength sheet steel. The
materials used have been selected for
their abilit y to withstand load, yet they
are considerably lighter than conventional
steel. As a result, the bodyshell of the
new Boxster models has a light alloy con -
tent of approximately 46 %. On the ecological side, all materials used
are meticulously selected. We use only
innovative and environmentally friendly
components. All synthetic components
are easily recyclable and each material

is labelled to facilitate its separation for
recycling. The reduction in the number
of plastic variants helps to ensure more
ef ficient recycling. Recycled plastics are
used where they meet our exacting technical requirements. In short, the new
Boxster is around 95
% recyclable.
In addition, Porsche uses a high propor -
tion of environmentally friendly water-
based paints. For us, 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 designed to
operate on fuels with an ethanol content
of up to 10 %. Ethanol has a positive
impact on the CO
2 balance since the
plants grown for the production of this
biofuel also absorb CO
2 from the atmos -
phere. The release of hydrocarbons from the fuel system has been minimised
thanks to the active carbon filter and the
multilayered material from which the fuel
tank is made. All fuel lines are made from
multilayered plastic, steel or aluminium.
Servicing.
Long service intervals offer clear advan
-
tages. For you, they reduce costs and
save time. For the environment, they
assist in the sparing use of consumables
and replacement parts. For full details
of service intervals, please refer to the
separate price list.
