The one confirmed engine for the American version of the 2011 Chevrolet Cruze is a new 1.4-liter turbocharged 4-cylinder engine. The company predicts 140 horsepower and fuel economy as high as 45 mpg, presumably on the highway. By contrast, the 2009 Cobalt's base 2.2-liter non-turbo four produces 155 horses and is EPA-rated at 25/37 mpg city/highway in new gas-miser XFE trim. In Europe at least, transmissions will comprise a 5-speed manual and an optional 6-speed automatic versus Cobalt's 5-speed manual and 4-speed automatic. Gearing will be chosen with an eye to maximizing fuel economy without compromising low-rpm performance. At some point, Chevrolet might add a sporty Cruze akin to the current Cobalt SS, perhaps with the same 260-horsepower 2.0-liter turbocharged 4-cylinder. The decision will hinge on buyer sentiment and how much higher gas prices go in the next couple of years.
