Volkswagen AG has admitted to diesel emissions cheating on its larger luxury cars and SUVs.
VW told U.S. regulators this week that an additional 75,000 vehicles dating back to 2009 were affected by the cheating.
The Volkswagen emissions cheating scandal up until this point was focused mainly on smaller-engined, mass-market cars, and raised the possibility that engineers at both the Audi and VW brands could have been involved in separate emissions schemes.
On Thursday, VW and Audi told the EPA that the issues extend to all 3-liter diesel engines from model years 2009 through 2016. The EPA says that admission of guilt involves 85,000 additional vehicles.
