EPA says VW intentionally violates clean air standards

WASHINGTON — Diesel cars from Volkswagen and Audi cheated on clean air rules by including software that made the cars look cleaner than they actually were, according to federal and California regulators.
The regulators say that the software on the cars turned up the emission controls only when it could tell that the car was being tested.
“The effectiveness of these vehicles’ pollution emissions control devices is greatly reduced during all normal driving situations,” said
