Fuel mileage, meanwhile, is seen as roughly five-percent better than in the C250 Sport sedan with 1.8-liter turbo, so around 23 miles per gallon in the city and 33 mpg highway.
Figure around 30 miles per gallon on the highway
Since it's a brand-new vehicle still months from sale in the U.S., the 2014 Mercedes-Benz CLA 250 hasn't yet been rated for fuel economy.
Gas mileage should be significantly better than in the larger C-Class, Mercedes predicts, since the CLA 250 weighs less, has less aerodynamic drag and has a more efficient transmission than the rear-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.
It's almost a lock that the CLA 250 will sport an EPA highway rating of more than 30 mpg when it hits U.S. showrooms this fall--the question is, will it nudge the 35-mpg mark? Whatever the final figure, expect all-wheel-drive versions to lose a mile per gallon on each side of the cycle due to the weight and efficiency loss of the system.
Though diesel versions are offered in other markets, there's no plan to introduce them on the U.S.-market CLA.
Gas mileage should sail by the EPA's 30-mpg highway rating, but will it hit 35 mpg?
