Until now, American and Japanese automakers have resisted adding diesel technology to their passenger car lineups. General Motors has now confirmed its plan to add a high-mileage diesel to its Chevrolet Cruze line starting with the 2013 model year. Likely to be an adaptation of the 2.0-liter VCDi direct-injection “oil-burner” now offered in Europe on their version of the Chevy compact, the diesel could deliver as much as 51 miles per gallon, exceeding that of the Cruze ECO and almost matching the Prius.
