Fuel efficiency has been slipping on the 2011 Chevrolet Cruze even before its North American debut. A couple years ago, then-General Motors chairman and CEO Rick Wagoner announced the car would achieve 42 mpg highway with a manual transmission. Since then, GM officials have toned that down just slightly, to "about 40 mpg" on the EPA highway loop. Whatever the actual mileage, the Cruze will achieve it with a 1.4-liter turbo four. But that new engine will be an option over the base 1.8-liter normally aspirated four that powers the European-market Cruze already on sale.
