2014 Chevrolet Impala: 21/31 mpg, 25 mpg combined (four-cylinder); 19/29 mpg, 22 mpg combined (V-6); 25/35 mpg, 29 mpg combined (eAssist)
The eAssist version is similar to a hybrid and should get up to 35 mpg on the highway.
Gas mileage won't be the first reason the Impala ends up on anyone's shopping list, and the V-6 versions are set to earn EPA ratings a few miles per gallon lower than some other big four-doors.
The EPA has published the Impala's gas-mileage ratings, and they confirm Chevy's estimates of 19 miles per gallon city, 29 miles per gallon highway, or 22 mpg combined, for the V-6 model. The combined number falls below the Toyota Avalon's 25 mpg, the V-6 Taurus' 23 mpg combined, and the 23-mpg figure posted by the Hyundai Azera and the Dodge Charger with its new eight-speed automatic. In our first-drive test loop set up by Chevy, the Impala's indicated economy checked in at 20.3 mpg, tallied after lots of canyon runs and a few stretches of 75-mph interstate.
Four-cylinder versions brighten the picture. With eAssist models, the addition of special aero add-ons--dams, spats, and active grille shutters that smooth the nose for better efficiency help the Impala equal the Buick LaCrosse eAssist's 29-mpg combined figure. That's above and beyond the turbocharged EcoBoost Ford Taurus' 26 mpg--but well off the mark of the Toyota Avalon Hybrid's 40-mpg combined EPA rating.
Four-cylinder Impalas earn a rating of 21/31 mpg, or 25 mpg combined.
Other full-size sedans earn better EPA figures than the new Impala.
