The 911 | Environment
technological development s are
carried out with
env ironmental
protection in mind. The goal?
Pure performance—
but not at
the expense of the environment.
The result? The 911. Find out

Exhaust emissions control.
Both 911 engines comply with
stringent emissions standards,
including Euro 5 in Europe
and LEV II i n the USA. Vehicles
manufactured by Porsche
demonstrate tha t even high-
performance sports cars can
achieve moderate emissions
values in their respective
categories. Indeed, no t only
is the 911 one of the most
exciting cars aro und, but it is
also one of the cleanest.
This is achieved through the
use of a two-stage cascade-
type catalytic converter which
compr ises two monolith
substrates on each of the twin
exhaust tracts. These specially
coated substrates contain ultra-
f ine honeycomb channels in
which pollutants are converted
as exhaust gas passes
through.
The stereo Lambd a Sensor
®
circuitry controls and monitors
each cylinder bank
separately,
while another Lambda Sensor
®
on each cylinder bank monitors
pollutant conversion in the
respective catalytic converter.
Fuel economy and recycling.
At Porsche, a fundamental as pect
of desi gn is intellige nt lightweight
co nstruction. For both economical
and ecological reasons. This
forms the basis for low fuel
consumption values in conjunction
with outstanding perfor ma nce.
It is economical, thanks to the
high proportion of alumi num
cast alloys, magnesium, plastics
and super high- strength sheet
steel used. T his is s ubstantially
more stable and lighter than
conven tional steel. In the 911
models, approximately 20
percent of components is
made from lightweight alloys.
It is also ecological because all
materials used are meticulously
selected. We use only innova tive
and environm entally friendly
components. All lig htweight
materials are easily recyclable
and each material is labeled
to fa cilitate it s separation for
recycling. The reductio n in
the number of plastic variants
helps to ensure more efficient
recycling. Recycled plast ics
are used where they meet our
ex acting technical requirements.
This all combines to make the
current 911 approximately
95-percent recyclable.
In addition, Porsche primarily
uses environmentally friendly
water-based paints. The 911 is
absol utely free of asbestos, CFCs
and component s manufact ured
using C FCs. This is because,
here at Porsche, e nvironmental
protection does not begin at
the end of a vehicle’s life.
It starts at the planning and
development stage.
