converter to reach normal operating
temperature sooner after a cold start and
a higher maximum torque to be achieved.
DFI improves the internal cooling of the
combustion chamber by having the
mixture prepared directly in the cylinder.
This allows for a higher compression ratio,
which helps to deliver higher power output
at the same time as enhanced engine
efficiency. Injection is regulated by the
electronic engine management system
and emissions are monitored by the stereo
Lambda sensors.
Direct fuel injection (DFI).
Direct fuel injection (DFI) is featured
as standard in both Boxster models.
Multi-hole injectors deliver fuel directly
into the combustion chamber with milli -
second precision. The injection pattern
has been optimised for torque, power
output, fuel consumption and emissions.
With direct injection, the engine manage -
ment system regulates injection timing
individually for each cylinder, as well as
the injection rate for each cylinder bank.
This optimises the combustion process
and therefore fuel economy. Depending
on the engine operating conditions, multi -
ple fuel injections can take place on each
operating cycle. This allows the cataly tic
Resonance intake manifold.
The resonance effect, where the air mass
inside the intake manifold is caused to
oscillate, is used to optimise the induction
process at all engine speeds. The engine
in the Boxster S is additionally equipped
with a switchable resonance valve.
The results are high torque, a flat ter
torque curve and high power output.

The sound produced is characteristically
resonant and deep, as you would expect
of a Boxster.

2 Boxster S t win tailpipemonitors 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 Boxster
models is the sports exhaust system
including sports tailpipe. It produces an
even more resonant Porsche sound.
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 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)

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

the driving conditions and modifies the

damping force on each of the wheels in
accordance with the selected mode.
Sensors record the body movements that
accompany powerful acceleration, brak

intelligent adaptation of damper stif fness
for the selected mode, optimising contact

Optional PASM, the electronic damping
control system, suits the Boxster models

continuously regulates the damping force

suspension features lightweight spring-strut
axles with longitudinal and transverse
links and, at the front, cross members

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

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.

The goal is to enhance performance –

but, where possible, not at the expense

Exhaust emission control.
Vehicles manufactured by Porsche
demonstrate that even high-performance
sports cars can achieve moderate fuel
consumption and exhaust emission values
in their respective category.
This is achieved, on the one hand, through
the use of fuel - ef ficient technologies such
as auto start /stop, thermal management,
electrical system recuperation, direct fuel
compared with the respective previous
model, even though performance has
been increased in every generation. This
is made possible by an efficient drive
concept (e.g. direct fuel injection (DFI) and
VarioCam Plus), lightweight construction,
optimised aerodynamics and low rolling
resistance.
The environmental management team

at the Porsche Development Centre in
Weissach aims to demonstrate a high
level of environmental responsibility. Here,
technological developments are carried
out with environmental protection in mind.
If we are to continue to enjoy driving
pleasure, we need to look after our

environment. In other words, we need to
take responsibilit y. In an era of intensify -
ing debate about global climate change
and CO
2 emissions, every automotive
manufacturer is asking itself what it
has to offer in terms of environmental
protection. Our answer has long been
the same: a combination of high power
output and high efficiency.
