to calculate the actual direction of travel

to oversteer or understeer, PSM applies

When the car is driven assertively into

a corner, moderate brake pressure is
applied to the inside rear wheel. Conse -
quently, a greater amount of drive force
is distributed to the outside rear wheel,
inducing an additional rotational pulse Porsche Torque Vectoring (PTV).

G -Force graphic on the TFT screen in
the right-hand circular instrument enables
you to view the lateral and longitudinal
forces as they act on the vehicle.
Using the SPORT or SPORT PLUS but ton
you can switch the dynamic gearbox
mounts from ‘Normal’ to ‘Sport ’ or

‘Per formance’ mode and intensif y your
driving pleasure. This results in greater traction, perceptibly
more stable handling under load change
conditions and in fast corners and, in
conjunction with the ‘Launch Control’
function for example, extremely fast
acceleration.
Dynamic gearbox mounts minimise this
effect. Steering angle and both longitudi
-
nal and lateral acceleration are constantly
recorded by sensors. The stiffness and
damping performance of the gearbox
mounts adapt to changes in driving st yle
and road surface conditions, which is
achieved by use of a fluid with magnetic
properties.

of the entire drivetrain, especially the

The gearbox is bolted to the body by t wo
mounts. Like any mass, it obeys the law

of inertia. This means that it will continue
moving in a uniformly straight line unless
some force causes it to change direction. Dynamic gearbox mounts.

On the other hand, newly developed

monitors each cylinder bank separately.
For each exhaust tract, oxygen sensors,
together with the engine electronics
and injectors, regulate the composition
of the exhaust gas, while another
Lambda sensor on each cylinder bank
monitors pollutant conversion in the
respective cataly tic converter.
The goal is to enhance performance –

but, where possible, not at the expense
of the environment.
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.
In recent years Porsche has managed to
reduce fuel consumption across all model
ranges by a double - digit percentage

Both
Boxster models are designed to
operate on fuels with an ethanol content
of up to 10 %. Ethanol has a positive
impact on the CO

Boxster is around 95 % recoverable.
In addition, Porsche uses a high propor -
tion of environmentally friendly water-
based paints. For us, environmental
protection does not begin at the end of
a vehicle’s life. It starts at the planning
and development stage.
On the ecological side, all materials used
are meticulously selected. We use only
innovative and environmentally friendly
components. All synthetic components
are easily recyclable and each material

is labelled to facilitate its separation for
recycling. The reduction in the number
of plastic variants helps to ensure more
ef ficient recycling. Recycled plastics are
used where they meet our exacting
On the technical side, various compo
-
nents are made with a high proportion of
aluminium, magnesium, plastics and
super high-strength sheet steel. The
materials used have been selected for
their abilit y to withstand load, yet they
are considerably lighter than conventional
steel. As a result, the bodyshell of the
Boxster models has a light alloy content
of approximately 46 %.
Fuel economy and recycling.
Intelligent lightweight construction has
been fundamental to the Porsche identit y
since 1948 for both technical and ecolog -
ical reasons. This forms the basis for
achieving low fuel consumption values in
conjunction with outstanding perfor -
mance.
