Auto start/stop function.
The auto start/stop function, which is
integrated as standard in the Boxster
models, switches off the engine when
you stop, select neutral and release the

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 long er-
lasting driving pleasure.
initiation of targeted braking. During this

process, any braking by the driver is
boosted to achieve the maximum braking
force that the system is able to provide.
Electrical system recuperation.
For enhanced ef ficiency the 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.
For increased safet y, the system also
readies the brakes whenever it detects
that the distance from the vehicle is

decreasing. However, the driver should
be prepared to intervene manually if
heavier braking is required. As soon as
the road ahead clears, your vehicle will
accelerate back up to the cruising speed
originally set.
Porsche Active Safe (PAS) issues an audi -
ble and a visual warning if the system
detects that your vehicle is approaching
the vehicle in front too quickly. This is
accompanied by a brief application of
brake force and, where necessary, the

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 millisec-
onds, delivering gear changes with no loss
of drive.

Porsche Doppelkupplung (PDK).
Available as an option for the Boxster
models is 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 man-
ual gearbox, very short response times,
reduced fuel consumption and a distinct
increase in comfort.
In total, PDK has seven forward gears at
its disposal. Gears 1 to 6 have a sports
ratio and top speed is reached in 6th gear.
For fuel consumption, CO2 emissions and efficiency class please refer to page 131.
Six-speed manual gearbox.
Both 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 ascending 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. In con-
junction with the optional Sport Chrono

accelerator or brake pedal, PDK re-en -
gages the appropriate gear within frac -
tions 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.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 100 km/ h to 80 km/ h in anticipa -
tion of the change of speed limit ahead.
As you ease off the accelerator pedal,
PDK deselects the current gear automa -
tically and you begin
to coast in neutral

suspension features lightweight spring-strut
axles 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

Even when you want to make a break
from everyday life, you should still keep
your feet on the ground.
The chassis of the Boxster models are an
excellent match for the powerful engines.
Axle components are made predominantly
of aluminium. This lightweight material
helps to keep the weight of the vehicle and
its unsprung masses low, which reduces
fuel consumption, improves comfort and
increases agilit y.

road. The optional Porsche Ceramic
Composite Brake (PCCB) is a fine exam-
ple. This brake system has already had
to cope with the harshest requirements
of motor racing and is fit ted in cars
that compete in demanding events such
as the Porsche Mobil 1 Supercup.
The cross- drilled PCCB ceramic brake

discs for the Boxster have a diameter of
350 mm front and rear for even more
formidable braking performance.
The use of six-piston aluminium mono -
bloc fixed brake calipers on the front axle
and four-piston units at the rear – all
finished in yellow – ensures extremely
high brake forces which, crucially, are
exceptionally consistent.
The dynamics of the Boxster and
Boxster S also demand appropriate brake
discs. All Boxster brake discs are intern -
ally vented and cross-drilled for improved
braking in wet conditions. With a diame -
ter of 330 mm, the front brake discs of
the Boxster S are 15 mm larger than
those of the Boxster. The diameter of
the rear brake discs is 299 mm on both
models. The brake calipers on the
Boxster and Boxster S are black and red,
respectively.

Brakes.
Porsche brakes set standards worldwide
for stopping power and stability. For the
Boxster models, braking per formance is
as essential as driving performance.
Both models are equipped with four-
piston aluminium monobloc fixed calipers
at the front and rear. This design means
that, not only are the brakes extremely
resistant to deformation, they are light -
weight for a particularly fast and sensitive
braking response.
Large brake calipers help to provide
excellent braking and component stability
even during continuous use. These t wo
characteristics have also been optimised
by the brake ventilation system with air
spoiler at the front and rear axles.
