The 2015 Chevy Cruze diesel is the last affordable family car in the U.S. with a diesel powerplant. Chevy has not announced details on a 2016 and the EPA has not certified it yet. The Cruze offers good drivability, but its fuel economy rating is only average for the class at 33 MPG combined. The gasoline Cruze Diesel Eco matches that number. The Toyota Corolla LE Eco earns a 35 MPG rating, which we exceeded in our testing of the car. Most of the top sellers in the affordable compact sedan and hatchback class can match the combined EPA rating of Chevy and VW's diesel cars.
