The engine that might be used in North America will be a modified version of the General Motors corporate 2.0-liter turbodiesel. It is already available in Cruze models sold in Europe and, as the Holden Cruze, in Australia, among other markets.
What can we expect in the U.S.? We do know that in Australia, the 2.0-liter common-rail turbodiesel engine is rated at 148 horsepower (110 kW) and a strong 236 foot-pounds (320 Newton-meters) of torque. It is offered with a five-speed manual gearbox or a six-speed automatic transmission.
In the U.K., the Chevrolet Cruze 2.0 VCDi model with the same engine delivered 42.0 miles per gallon (50.4 miles per Imperial gallon) on the European test cycle. It cost £17,325 (roughly $28,250 including tax) as tested by Autocar magazine in September 2009.
While diesel engines are more efficient and deliver better MPG figures than gasoline engines of the same power, they do not represent a large portion of the U.S. passenger vehicle market.
