SULEV 2.0L TFSI Engine
Compliance with Statutory Limits
(PremAir®)
When evaluating the environmental compatibility of
vehicles, the EPA awards “credits” for technical measures
designed to improve air quality. These credits can be
used to offset fleet emissions that are over the limit.
For this reason, a radiator with a special catalytic coating
is used on the Audi A3.
This PremAir® technology* contributes to improving air
quality. In exchange, the California Air Resources Board
allows a higher NMOG* limit.
*NMOG
This abbreviation stands for “Non Methane Organic
Gases” and encompasses all hydrocarbon emissions
except methane.
