The Environmental Protection Agency announced Monday that it has expanded its probe into the Volkswagen emission scandal, finding at least six more affected vehicle lines including Audi and Porsche models.
EPA officials said that a number of 2014-2016 models from VW, Audi and Porsche, equipped with 3.0 liter engines, employed defeat devices to trick emission standard tests. EPA Assistant Administrator Cynthia Giles said these vehicles, “emit up to nine times as much NOX as is allowed.”
Porsche was a surprise name on the list as the Volkswagen owned brand denied any involvement in emission cheating in September. Matthias Muller, then head of Porsche was even tapped to replace the embattled Martin Winterkorn as CEO of Volkswagen.
