2012 Mercedes-Benz E Class Fuel Economy

7.0
Fuel Economy

Thanks to a new lineup of direct-injection V-6 and V-8 gasoline engines, the 2012 Mercedes-Benz E Class models are significantly more fuel-efficient than last year's models.

E350 models now rate up to 20 mpg city, 30 highway, while E550 models get up to 17/27. 4Matic all-wheel drive drops estimates by up to several miles per gallon, depending on the model and the body style.

Gasoline versions of the 2012 Mercedes-Benz E Class lineup are more fuel-efficient than before, but the BlueTec turbodiesel is still the green pick.

Even considering the improvements in those gasoline engines, you're still going to keep things clean--and the most fuel-efficient--with the E350 BlueTec Sedan. At 21 mpg city and 32 mpg highway, it's the greenest of the E Class bunch.

And if you're even reading this section, you probably aren't considering the high-performance E63 AMG models. Rated as low as 15 mpg city, 23 highway, they're guzzlers, albeit very rewarding ones.
