In January 2016, the Department of Justice filed a complaint on behalf of EPA alleging that Volkswagen, Audi, and Porsche (“Volkswagen”) violated the Clean Air Act by equipping its 2.0 and 3.0 liter diesel vehicles with software intended to deceive emission tests. The complaint covers all of Volkswagen’s model year 2009 – 2016 U.S. model light-duty diesels. Under settlement of the complaint, Volkswagen proposed technical remedies to remove the illegal software and address the excess emissions from the affected vehicles. EPA and the California Air Resources Board (CARB) approved most of Volkswagen’s proposed emissions modifications. The new, confirmed fuel economy estimates for the modified vehicles are available on fueleconomy.gov. The proposed remedy for model year 2012-2014 2.0L diesel Passat manual transmission vehicles was not approved. The original fuel economy data for these vehicles has been removed from fueleconomy.gov.
