Exhaust emission control.
The new 911 GT3 complies with
stringent emissions standards,
including Euro 5 in Europe and
LEV II in the USA. Porsche vehicles
demonstrate that even high-
performance sports cars can
achieve moderate emission values
in their respective category. The
911 GT3 is not only one of the
most powerful sportscars, but it
is also one of the cleanest.
This is achieved using two
catalytic converters and an
oxygen-sensor control system.
The two banks of cylinders are
monitored separately. Two corre-
sponding oxygen sensors control
the exhaust gas composition
individually for each exhaust sec-
tion. In addition to this, another
sensor for each bank of cylinders
monitors the conversion of pollu-
tants in each catalytic converter.*
Noise.
The new 911 GT3 complies with
all valid noise requirements in
the countries where it is sold
without any form of engine
encapsulation. To achieve this,
noises are eliminated at source.
It sounds paradoxical, but
without any noise there is only
one pure sound.
Servicing.
Long service intervals offer clear
advantages. For you: lower
costs and saved time. For the
environment: the use of fewer
consumables and replacement
parts. For details of the service
intervals for the 911 GT3, please
refer to the separate price list.

In an era of intensifying debate
about CO
2
emissions, every
automotive manufacturer is being
asked the question, ‘What is
your answer to the issue of fuel
consumption?’ Our answer has
long been the same: maximum
efficiency.
Porsche has been reducing the
CO
2
emissions of its vehicles
annually by an average of around
1.7%. In relation to engine power,
Porsche is already among those
manufacturers achieving the
lowest CO
2
emissions. This has
been achieved through a new
efficient drive concept, optimum
aerodynamics, low rolling resis-
tance and lightweight construction.
This high level of environmental
responsibility is demonstrated by
our approach to environmental
management at the Porsche
development centre in Weissach.
Here, all technological develop-
ments are carried out with environ-
mental protection in mind. The
objective is to achieve
pure performance, but not at the
expense of the environment.
It’s all about efficiency.
And your relationship with the environment.
*Except in countries with leaded petrol.
Fuel.
Today’s Porsche sportscars are
already designed to run on 10 %
ethanol. Ethanol has a positive
impact on the CO
2
balance since
the plants grown for the produc-
tion of this biofuel also absorb
CO
2
from the atmosphere.
Fuel system.
In the fuel system of the new
911 GT3, the emission of hydro-
carbons has been minimised.
This is achieved through a large
active carbon filter and a special
coating on the fuel tank. All pipes
that carry fuel are made from
aluminium, while vapour-carrying
lines are made from multi-layered
plastic.
