2014 BMW 4-Series Fuel Economy

7.0
On Fuel Economy

Luxury sports coupes aren't always the best choices for drivers concerned with gas mileage, but the BMW 4-Series takes extensive measures to make fuel economy less of an issue.

BMW outfits every model with stop/start and an EcoPro mode, which slows down the throttle tip-in and softens automatic-transmission shifts, as well as shutting down some of the constantly running accessories and climate control systems, all in the name of saving fuel. It also has electric power steering, which reduces feedback, but also reduces gas consumption. And it's lost a little weight, too: it's up to almost a hundred pounds lighter than the 3-Series Coupe it replaces.

At 26 mpg combined max, the BMW 4-Series acquits itself well for a luxury coupe.

The result is a 27-mile-per-gallon rating on the EPA's combined cycle for the base 428i equipped with the eight-speed automatic; with the six-speed manual, the 4-Series still earns 26 mpg combined. Adding all-wheel drive to the automatic puts the 428xi at 26 mpg combined.

Gas mileage isn't even that awful with the very powerful twin-turbocharged six-cylinder. The 435i with the automatic earns an EPA-certified 25 mpg combined, or 24 mpg combined with all-wheel drive. With the manual transmission and either rear- or all-wheel drive, the 4er posts a 23-mpg combined rating.

Though there's an ActiveHybrid edition of the 3-Series sedan, it's not expected to make an appearance in the 4-Series lineup any time soon.
