2014 Mercedes-Benz CLA Class Fuel Economy

The 2014 Mercedes-Benz CLA 250 earns gas-mileage ratings that are significantly better than in the larger C-Class, at least in the CLA 250. The front- or all-wheel-drive sedan weighs less than the C-Class, has less aerodynamic drag and has a more efficient transmission than that rear- or all-wheel-drive sedan. It also has standard stop/start, which shuts down and reawakens the CLA when it pauses at stoplights. It's smooth enough, but the stop/start effect sends a quiver through the driveline.

The result is an EPA rating of 26 miles per gallon city, 38 miles per gallon highway, and 30 mpg combined. We've driven the CLA 250 extensively now in the U.S., and have earned more than 37.3 mpg on long interstate runs, without much modulation of our driving habits.

The CLA 250 gets excellent EPA ratings of up to 30 mpg combined--and they're within easy reach.

The EPA says the all-wheel-drive versions of the CLA 250 are rated at 24/32 mpg, or 27 mpg combined. The rip-roaring CLA45 AMG? It's remarkably as good as 23/31 mpg, 26 mpg combined.

Though diesel versions are offered in other markets, there's no plan to introduce them on the U.S.-market CLA.
