Audi Quattro
The [[EPA]] revealed on 2 November 2015 that Volkswagen had shipped additional diesel models with defeat devices, including the 2014 [[VW Touareg]] and the 2015 [[Porsche Cayenne]]. Model year 2016 Audi Quattro diesels were also found affected, including several 2016 Audi Quattro models (the 2016 Audi Quattro [[Audi A6|A6]], [[Audi A7|A7]], [[Audi A8|A8]], A8L, and [[Audi Q5|Q5]]). Cynthis Giles, the EPA Assistant Administrator for Office of Enforcement and Compliance Assurance, called out the company for further refusing to take responsibility for its failure to comply with the law. Under US federal Clean Air Act, Volkswagen could be liable for up to $375 million in fines.
