Volkswagen emissions saga continues as EPA widens its probe by Benjamin Snyder @FortuneMagazine October 2, 2015, 11:35 AM EDT E-mail Tweet Facebook Linkedin Share icons The EPA is investigating two dozen diesel car models made by BMW, Chrysler, General Motors GM , Land Rover, and Mercedes-Benz over emissions to check whether or not they, like Volkswagen, installed “defeat devices” to mask actual emissions. The Financial Times reported that at least 28 models will be tested in the widened probe. There are a slew of diesel vehicles in line to be tested, according to the FT, including: BMW’s X3; Chrysler’s Grand Cherokee; GM’s Chevrolet Colorado; the Range Rover TDV6; and the Mercedes-Benz E250 BlueTec. The move comes as Volkswagen sales actually rose in September. Meanwhile, the EPA has said it will change the way it tests diesel models in an attempt to prevent similar emissions scandals going forward. Matthias Müller was recently named Volkswagen’s new CEO after the departure of Martin Winterkorn in September.
