You aren’t the only one looking for ways
to improve your performance. In an
era of intensifying debate about global
climate change and CO
2
emissions,
automotive manufacturers are among
those asking themselves how they can
contribute to environmental protection.
Our answer has long been the same:
Intelligent Performance—a combination
of high power output and high efficiency.
In recent years, Porsche has increased
efficiencies in fuel consumption across all
model ranges, even though performance
has been increased in every generation.
This is made possible by an efficient
drive concept, including Direct Fuel
Injection (DFI) and VarioCam Plus, a
lightweight construction, optimized
aerodynamics, and low rolling resistance.
The environmental management team
at the Porsche Development Center in
Weissach demonstrates a high level
of environmental responsibility. Here,
technological developments are carried
out with environmental protection in mind.
The goal is to enhance performance,
but preferably not at the expense
of the environment. We achieve this

goal with Intelligent Performance, as
epitomized by the new Cayman.
Emissions Control
Vehicles manufactured by Porsche
demonstrate that even high-performance
sports cars can achieve moderate fuel
consumption and exhaust emissions
values in their respective category.
This is accomplished by the use of
fuel-efficient technologies such as
Auto Start Stop, thermal management,
electrical system recuperation, Direct
Fuel Injection (DFI), VarioCam Plus,
and, in conjunction with the optional
PDK, coasting mode. The newly
developed catalytic converters also
provide efficient emissions control,
while the stereo lambda control circuitry
manages and 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 catalytic converter.
