EPA: We caught VW in more emissions cheating


The U.S. Environmental Protection Agency says it has discovered more "defeat devices" in vehicles with diesel engines made by Volkswagen.

In September, the EPA said it had discovered emissions cheating in 482,000 VW and Audi diesel cars, which were equipped with software that could detect when there was an emissions test happening.  The cars' emissions controls would turn on for the test, and turn off during normal driving.

The cheat resulted in emissions of nitrogen oxides, regulated pollutants, 40 times higher than the standard, said the agency.

In a conference call with media today, EPA officials say further tests show the devices were also installed in diesel versions of the 2014 VW Touareg, the 2015 Porsche Cayenne, and the 2016 Audi A6 Quattro, A7 Quattro, A8, A8L, and Q5.

The agency is testing diesel cars made by other automakers, but so far, those cars have come up clean.

VW is facing an international firestorm of criticism, because the cheat was employed in many of its cars worldwide.  The emissions from the cars also violate European standards as well as many other countries' standards.

The scandal is expected to cost VW billions of dollars in fines, recall costs, vehicle re-manufacturing, and lawsuits.
