this is detected by the radar sensor. The
system now reduces the speed of your
vehicle by restricting throt tle or by gently
applying the brakes until your chosen
distance from the vehicle in front is main -
tained. If the vehicle ahead slows further,
regulates the speed of your vehicle in line
with the speed of the vehicle in front. A

radar sensor scans the road ahead up to
a distance of 200 m.

The auto start /stop function can be
deactivated and reactivated using a sepa-

function may be deactivated automatical-

example in extreme outside tempera

tures, when the SPORT but ton is selected
or when there is low bat tery charge.
All audio and commu nication systems
remain switched on. The engine will
restart as soon as you operate the clutch
or, in cars with PDK, release the brake.
This fuel-saving innovation is designed
primarily for use in towns or congested
motorway traffic.
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
clutch pedal.
In cars with Porsche
Doppelkupplung (PDK), it is simply a
case of applying and holding the brake.

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.

advantages of PDK are brought into play:

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.

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

your desired
speed. As soon as you

With the optional Sport Chrono Package,
PDK is enhanced by the ‘Launch Control’
and ‘motorsport- derived gearshif t strat-
egy’ functions (p. 65) for even faster and

firmer gear changes and the best possible
performance thanks to a boost in torque

Please note that circuit racing, trackday

driving can significantly reduce the
service life of even the most durable
pads and discs. As with conventional
high-performance braking systems,
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,

Another key advantage of PCCB is the
