Environment.
We’ve already spoken about our contribu
tion to motorsport. To be more precise,
about our responsibility for the future of
motorsport. We meet this responsibility
with intelligent technology, unconven
tional ideas and optimum performance.
Our approach to environmental protec
tion is no different. In an era of intensify
ing debate about global climate change
and CO
2 emissions, every automotive
manufacturer is asking what it has to
offer right now. Our answer has long
been the same: high power output
combined with high efficiency.
Porsche has managed to reduce fuel
consumption significantly across all
model ranges compared with the respec
tive previous model even though perfor
mance has been increased. This is made
possible by an efficient drive concept,
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. The goal is to enhance perfor
mance – but preferably not at the expense
of the environment.
Fuel economy and recycling.
Intelligent lightweight construction has
been part of Porsche DNA since 1948 –
for both technological and ecological
reasons. And, of course, with competitive
advantages in mind. In motorsport, weight
is increasingly the number one factor
of success. Lightweight construction is
therefore the basis for low consumption
The true challenge:
not merely getting faster, but better.
values combined with outstanding
performance.
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 overall than
conventional steel.

On the ecological side, all materials used
are meticulously selected. Each light
weight material is easily recyclable
and all plastic components are labelled
to facilitate separation for recycling.
The
reduction in the number of plastic
variants helps to ensure more efficient
recycling. Recycled plastics are used
where they meet our exacting technical
requirements.
In short, the new 911 GT3 is around 95 %
recoverable. In addition, Porsche uses a
high proportion 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.
Emission control.
The new 911 GT3 meets the strict Euro 5
emission standard in the EU and LEV II
in the USA. Vehicles manufactured by
Porsche demonstrate that even high
performance sports cars can achieve
moderate emission values in their
respective category. This puts the new
911 GT3 among not only the most powerful sports cars of the future, but
also the cleanest.
This has been accomplished not least by
the t wo cataly tic converters and stereo
Lambda control circuits, which monitor
each cylinder bank separately. For each
exhaust tract, t wo Lambda sensors regu
late the composition of the exhaust gas.
Another Lambda sensor for each cylinder
bank monitors pollutant conversion in the
respective cataly tic converter.
Fuel.
All Porsche models – including the new
911 GT3 – are designed to operate on
fuels with an ethanol content of up to
10 %, e.g. ‘E10’. Ethanol has a positive
impact on the CO2 balance since the
plants grown for the production of
this biofuel also absorb CO
2 from the
atmosphere.
The release of hydrocarbons from the
fuel system has been minimised thanks
to the active carbon filter and the
multi layered material from which the
fuel tank is made. All fuel lines are
made from multi layered plastic, steel
or aluminium.
