The Environmental Protection Agency on Monday levied additional charges against Volkswagen, pulling its subsidiary Porsche into the global emissions-cheating scandal.
The agency also added a new engine — the 3.0-liter diesel six-cylinder — and several more models to the list of vehicles it says were illegally equipped. The models include the 2014 VW Touareg, the 2015 Porsche Cayenne and the 2016 Audi A6 Quattro, A7 Quattro, A8, A8L and Q5.
