Engine management.
The electronic engine management
system ensures optimum engine perfor -
mance at all times. It regulates all
engine-related functions and assemblies.
The results are optimum power output
and torque with comparatively low fuel
consumption and emissions. Another function is the cylinder-specific
knock control. Since engine cylinders
never all work under exactly the same
conditions, the knock control function
monitors each one separately. The igni
-
tion point is shifted individually, as and
when necessary, to protect the cylinders
and pistons at high engine speeds and loads. For compliance with EU Stand
-
ards, the on-board diagnostics detect
any faults and defects that may occur in
the exhaust and fuel systems and then
notify the driver immediately. This also
prevents increased pollutant emissions
and unnecessary fuel consumption.
SPORT button.
The SPORT but ton on the centre console
is fit ted as standard. When selected,
Sport mode is activated to provide
greater response and enhanced driving
pleasure. Throttle response becomes
even more direct, the rev-limiter is
adjusted to a harder set ting and engine dynamics are tuned for performance

driving. The auto start/stop function is
also deactivated. With the optional Porsche Doppelkupplung
(PDK) transmission, the shift points are
reconfigured are reconfigured to operate at higher engine speeds. Shift times are
reduced and gearshifts become firmer
and more immediate, while throttle-blip
downshifts are accompanied by an
emotive engine sound. Coasting mode
(p. 44) is deactivated automatically.
Auto start/stop function.
The auto start/stop function, which

is integrated as standard in the new
Boxster models, switches of f the engine

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

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.
