The U.S. Environmental Protection Agency has entered into multiple settlement agreements with the automaker Volkswagen for violating the federal Clean Air Act.
An investigation by the EPA revealed, and Volkswagen admitted, the company manufactured diesel vehicles with software installed that cheated emissions tests by only turning on the vehicle’s emission control systems when the car was being tested. Get more details.
