Mileage Wars Are On: Details on GM's New Four-Cylinder Engine
At GMC’s New York auto show display last week, we asked spokesman Randy Fox for more details about the automaker’s latest engine, a 2.4-liter four-cylinder that helps the GMC Terrain and Chevy Equinox achieve 21/30 mpg city/highway with front-wheel drive, according to preliminary EPA estimates. If the numbers pan out, that means the Terrain and Equinox will beat the thriftiest versions of the Ford Escape and Toyota RAV4 (both 22/28 mpg), as well as the Nissan Rogue (22/27) and Honda CR-V (20/27).
That’s just the beginning. The four-cylinder is a modular engine that will also make its way under the hood of the redesigned Buick LaCrosse, Fox said. How about the Chevy Malibu? Fox said it’s a possibility.
With fuel-saving — and power-increasing — direct injection, the engine makes 182 hp in the Equinox and Terrain. If that means the Malibu could make equivalent power (its four-cylinder currently makes 169 hp), that could help with highway passing — and bump mileage beyond the car’s current 22/33 mpg EPA rating. Unlike the horsepower wars, the mileage wars are something we can get behind. Ford stole the title of thriftiest non-hybrid family car with the 23/34 mpg Fusion. Can GM leapfrog that? We’ll have to wait and see.
