The 3.0-liter diesel engine also used “defeat devices?”
Just when we thought that things couldn’t possibly get much worse in the Volkswagen emissions scandal, it appears that “Dieselgate” is deepening once again. The U.S. Environmental Protection Agency (EPA) is now claiming that the use of “defeat devices” was not just limited to VW’s 2.0-liter diesel engines, but may also extend to 3.0-liter diesel engines used in Volkswagen, Audi and Porsche vehicles.
The 3.0-liter diesel engine now in question was developed by Audi and used in the 2014 VW Touareg, 2016 Audi A6 Quattro, A7 Quattro, A8, A8L, Q5 and 2015 Porsche Cayenne. These latest allegations widen the scope of the scandal and directly implicate Audi and Porsche. VW headquarters issued a statement vehemently denying any wrongdoing stating, “Volkswagen AG wishes to emphasize that no software has been installed in the 3.0-liter V6 diesel power units to alter emissions characteristics in a forbidden manner. Volkswagen will cooperate fully with the EPA to clarify this matter in its entirety.”
Porsche Cars North America was also quick to release a statement saying it was “surprised” by the allegations and stated that “the Porsche Cayenne Diesel is fully compliant”, but that the company “will cooperate fully with all relevant authorities.”
