Expert Quotes:

2014 Chevrolet Impala: 21 mpg combined (18 mpg city, 28 mpg highway) for the V-6 model; 25 mpg combined (21 mpg city, 31 mpg highway) for base 2.5-liter four; and 29 mpg combined (25 mpg city, 35 mpg highway) for Impala Eco.

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, with the base vehicle coming in at 25 mpg (21 mpg city, 31 mpg highway) and the more powerful V-6 at 21 mpg combined (18 mpg city, 28 mpg highway).

The combined 21-mpg rating for the V-6 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 V-6 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. We logged 25.1 mpg--right on the nose--for the base 2.5-liter four-cylinder Impala, albeit over a short 20-minute drive covering about 12 miles.

At the top of the fuel-economy list is the Impala Eco, fitted with GM's mild-hybrid eAssist system. The addition of special aero add-ons--dams, spats, and active grille shutters that smooth the nose for better efficiency--lets the Impala Eco equal the 29-mpg combined figure of the Buick Lacrosse that uses the same system. That's better than the 26 mpg of the turbocharged EcoBoost Ford Taurus--but well off the 40-mpg mark set by the Toyota Avalon Hybrid.

How does the
TCC Rating work?
The TCC Rating is a clear numeric rating value based on a 10-point scale that reflects the overall opinion of our automotive experts on any vehicle and rolls up ratings we give each vehicle across sub-categories you care about like performance, safety, styling and more.

Our rating also has simple color-coded “Stop” (red), “Caution” (orange),
or “Go” (green) messages along with the numerical score so you can easily understand where we stand at a glance.

Our automotive experts then also collect and show you what other websites say about these different aspects of any vehicle. We do this leg work for you to simplify your research process.
