Volkswagen cheated a second time
WASHINGTON- Volkswagen is accused of cheating on a second set of emissions tests, this one involving six-cylinder diesel engines.
The EPA says the automaker installed software designed to defeat emission on the 2014 to 2016 models. It previously admitted rigging emissions testing for four-cylinder diesel engines. EPA says the software has a timer that makes the cars perform differently when being tested then they perform on the road.
The agency charges the engines give off up to 9 times more nitrogen oxide pollution while being driven than they do when they're being tested.
