Engine management system
with electronic throttle.
The electronic engine manage -
ment system ensures optimum
engine performance under all
operating conditions. It regulates
all engine-related functions and
assemblies (see diagram). The
results: optimum performance
and torque with reduced fuel con -
sumption and emissions.
Another important function of the
system is cylinder-specific knock
control. Since the six cylinders
never all work under precisely
the same conditions, they are
monitored individually by the
knock control. If necessary, the
ignition point is shifted individu -
ally to protect the cylinders and
pistons at high engine speeds
and loads. The on-board diagnos -
tics, which are compliant with
European standards, ensure
timely detection of any faults and
defects that may occur in the
exhaust and fuel system in good
time and notify the driver
immediately. This also prevents
increased pollutant emissions
and
unnecessary fuel consumption.
Two-stage resonance intake
manifold.
The intake manifold with dual-flow
distributor pipe has an adjustment
valve which closes and opens at
set engine speeds. A t wo -stage
tuning effect creates oscillation
of the air mass in the intake
system, which in turn generates
a turbocharging effect and opti -
mises induction.
These t wo effects combine to
produce higher torque at low
engine speeds, a flat ter torque
curve, and increased power
output at high engine speeds.
The acoustic properties of the
system are second to none,
producing the characteristic
Boxster sound.

Radio functions include up to
42 memory presets and an FM
dual tuner with RDS and fre -
quency diversit y, which continu -
ously scans in the background
for the best signal. The integrated single CD/ DVD
drive – in combination with the
optional BOSE
® Surround Sound
System – is also able to play
back music from audio and video
DVDs in the 5.1 digital surround
format. An integrated six-disc
CD/ DVD autochanger with MP3
compatibilit y is also available as
an option for the PCM.
Navigation module for PCM.
The GPS navigation module
included with the optional PCM
now has an internal hard drive
containing maps for most Euro
-
pean countries.

A touchscreen enables rapid
destination input and instant
viewing of traf fic information and
points of interest (POIs) by simply
allowing you to touch the symbols
on the map. Route diversions,
e.g. the nearest service stations,
can therefore be incorporated
quickly and easily into the current
route guidance.
When viewing a map, it is pos -
sible to select bet ween a 3D
perspective and the 2D display.
At motorway exits, graphical
turn indications are displayed for
bet ter orientation. In splitscreen
mode, you can choose to display
not only the current map over-
view, but also a list of icons that
represent dynamic route guidance.
Electronic logbook for PCM.
The optional electronic logbook
enables automatic recording of
relevant driving data. Once you
have downloaded the logbooks
via Bluetooth® or the optional
USB interface, you can evaluate
them on your home PC using
the sof t ware supplied (sof t ware
complies with all statutory
requirements for automatic log-
books as specified by the
German revenue authorities).
TV tuner.
A T V tuner, available as an option,
receives free-to -air analogue and
digital broadcasts (DVB-T) and
provides entertainment bet ween
journeys. For your safet y, the
T V picture cannot be displayed
while the vehicle is in motion.
Voice control system.
Almost all of the functions of the
PCM can be controlled using
the latest optional voice control
system with word-by-word input.
The menu item is read aloud
exactly as it is displayed on the
screen and the voice control
system recognises commands or
sequences of numbers, whoever
the speaker. It then gives an
audible acknowledgement and
carries out the functions you
request. There is no need to ‘train’
the system.
Telephone module for PCM.*
Available as an option, the quad-
band GSM telephone module
of fers convenience and excellent
reception. Hands-free calls can
be made by inserting a SIM card
directly into the PCM’s integral
SIM card reader. And for even
more convenience, the Bluetooth®
capabilit y of your mobile phone
can be used to make calls through
the SIM Access Profile (SAP).
Once automatic pairing is com -
plete, the mobile phone’s aerial is
switched off to conserve bat tery
charge and the phone operates
via the car aerial. Depending
on the t ype of mobile phone, this
gives access not only to the
numbers on the SIM card, but also
to the phone’s internal memory.
