Thermal management.
The Boxster models feature a new version
of thermal management to reduce friction
losses that arise during the warm-up
phase.
Thanks to the selective control strategy
and on-demand, gradual activation of the
various cooling circuits, the engine and
gearbox warm up to normal operating
temperature more rapidly. The conse -
quent reduction in friction also reduces
fuel consumption and CO
2 em issio ns.
During sporty driving, thermal manage -
ment also acts to reduce temperatures
so that a high level of performance is
maintained. Our cross-flow cooling system, as used

in motorsport, supplies each engine
cylinder uniformly with coolant, which
protects the valves against thermal
overload and, therefore, premature wear.
This improves combustion and keeps
emissions, fuel consumption and noise
comparatively low.
Exhaust system.
In the new Boxster models, each cylinder
bank has its own stainless-steel exhaust
tract. Downstream of their respective
rear silencer, the tracts converge into
a connecting tube and a single (Boxster)
or t win (Boxster S) tailpipe. The stereo
Lambda control circuitr y controls and monitors each cylinder bank separately.
For each exhaust tract, four correspond
-
ing oxygen sensors regulate the composi -
tion of the exhaust gas and monitor the
performance of the catalytic converters.
Having separate tracts means that the
exhaust gas can flow more freely. The
resulting reduction in pressure loss has a
positive impact on power output, torque
and the unmistakable engine sound.
Available as an option for the new Boxster
models is the sports exhaust system
1)
including sports tailpipe. It produces an
even more resonant Porsche sound.

Exterior mirrors and rear-view mirror.
The new Boxster models are equipped
as standard with electrically adjustable
and heated exterior mirrors.
Available as an option, electrically folding
exterior mirrors with door courtesy light -
ing on both sides of the vehicle make it
easier to find your way in the dark.
An auto-dimming function for the exterior
mirrors and rear-view mirror with an
integrated rain sensor for the windscreen
wipers, is available as an option.
ParkAssist.
Optional ParkAssist is activated the
moment you select reverse gear.
An audible signal gives a warning if you
reverse too close to an obstacle.
An enhanced version of Park Assist also
provides monitoring of the area to the front of the vehicle. Ultrasonic sensors
are neatly integrated into the front and
rear aprons. The audible alert is supple
-
mented by a visual warning in the central
display of the CDR audio system or option -
al
PCM, which shows a graphical repre -
sentation of the vehicle from overhead.
HomeLink®
(programmable garage door opener).
The optional programmable garage door
opener is integrated into the overhead
console and remotely controls up to
three different garage doors, gates, home
lighting and/or alarm systems.

Anti-theft protection.
Both new Boxster models are equipped
as standard with an immobiliser with in-
key transponder and an alarm system

with contact-sensitive exterior protection.

Preparation Vehicle Tracking System
(PV TS).
This standard preparation enables future
installation of the Porsche Vehicle Tracking
System (PV TS) available from Porsche
Tequipment. The system makes it possible
to locate a stolen vehicle across most of
the countries of Europe. The preparation
package includes a special wiring loom
and a tilt sensor for the alarm system.
Two luggage compartments.
The t wo luggage compartments are
further proof that the Boxster harmoni -
ously combines the spirit of sport with
everyday practicality like never before.
The front and rear compartments have
a capacit y of 150 and 130 litres respec -
tively, regardless of whether the hood is
up or down. The interior surfaces are
carpet-lined and the lids are made from
aluminium. The two service openings in
the rear luggage compartment provide convenient access to the coolant and
engine oil filler caps.
The separate Porsche Design Driver’s
Selection catalogue contains a selection
of matching luggage accessories.
