concerned, we are already among
those manufacturers achieving
the lowest CO
2
emissions. This
has been achieved through the
new efficient engine technology
(e.g. by DFI and VarioCam Plus),
lightweight construction, optimum
aerodynamics and low rolling
resistance.
This high level of environmental
responsibility is clearly demon-
strated by our approach to envi-
ronmental management at the
Porsche Development Centre in
Weissach. Here, all technological
developments are carried out
with environmental protection in
mind. The goal is pure perform-
ance – but not at the expense of
the environment. A goal achieved
by the Panamera.
Fuel economy and emission
control.
Vehicles manufactured by Porsche
demonstrate that even high-
performance sportscars can
achieve moderate fuel consump-
tion and exhaust emission values
in their respective category.
The balance is exemplary: the
Panamera, Panamera 4 and
Panamera Turbo comply with the
Euro 5 emission standard in
Europe and the LEV regulations in
the USA, the Panamera S and
Panamera 4S meet the require-
ments of EU 5 and ULEV.
This is achieved through the use
of fuel-efficient technologies such
as direct fuel injection (DFI, p. 51)
and VarioCam Plus (p. 52).
Efficient emission control is
achieved by a two-stage cascade-
type catalytic converter, which
comprises two monoliths arranged
in series. These specially coated
substrates contain ultra-fine honey -
comb channels in which pollutants
are converted as exhaust gas
passes through.
The stereo Lambda control circuitry
controls and monitors each cylin-
der bank separately. For each
exhaust tract, oxygen sensors
regulate the composition of the
exhaust gas, while another Lambda
sensor on each cylinder bank
monitors pollutant conversion in
the respective catalytic converter.**
Environmental protection.
In an era of intensifying debate
about global climate change and
CO
2
emissions, every automotive
manufacturer is asking what it has
to offer in terms of environmental
protection. Our answer has long
been the same: maximum effi-
ciency. Porsche has been reducing the
CO
2
emissions of its vehicles
by an average of around 1.7 %*
every year for the past 15 years.
As far as engine output is

figures for the respective model years
of the vehicles and in relation to the
applicable European legislation.
