– Porsche develops and applies manufactur-
ing procedures that are as environmentally
friendly as possible.
– Porsche naturally meets all current environ
mental regulations.
– Porsche regularly informs the public of its
efforts with regard to the environment, and
aims to maintain open and cordial dialog
with authorities and organizations.
In the past, the company has also spent a great
deal of money on limiting its impact on the en-
vironment as much as possible. The refinement
of all model series in terms of their impact on
the environment is a high priority for the devel-
opment departments.
The fact that Porsche is continuously improving
the fuel consumption of its vehicles can be ex-
emplified by a comparison of a Carrera from the
year 1994 with a current model. Fifteen years
ago, the vehicle had a 3.6 -liter engine with 285
hp (210 kW) and consumed 14.4 liters per 100
kilometers. The 2009 Carrera, with exactly the
same displacement, has an output of 345 hp
(254 kW) but only requires 9.5 liters per 100 kilo-
meters. A one-third reduction in consumption
also dramatically reduced exhaust emissions.
The old Carrera was built according to the Euro 1
exhaust standard, while the current model meets
the much stricter Euro 5 requirements.
In the last 15 years, Porsche has reduced the
CO2 emissions of its vehicles by an average
of 1.7 percent each year. This decline has ac-
celerated significantly in the last four years.
If one compares the vehicle portfolio from 2006
with the portfolio for 2009, average consump-
tion has improved by 2.8 percent each year.
Porsche will continue along this path of con-
tinuously improving the consumption of all its
models in future and prove its competitiveness,
even in terms of their environmental impact.
In order to do justice to this important operating
goal, Porsche has created a department within
its development department that is responsible
for optimizing energy management. A significant
reduction in consumption can only occur if all
components and systems are optimized and net-
worked with regard to their energy efficiency.
Here, energy management concepts that are
heavily networked are developed for the entire
vehicle. The best evidence of the success of
these efforts lies in the excellent consumption
figures of the new Panamera.
Hybrid drive trains
nearing series production
In the past fiscal year development of a hybrid
drive train came a good step closer to series
production. This system, which has a particu-
