Overview

The W212 returned to a more angular, conservative design language and proved to be a significant reliability improvement over the W211. It offered a range of efficient turbocharged engines and refined the 7G-Tronic transmission. The facelift in 2014 brought LED headlights, a new steering wheel, and the M274 four-cylinder turbo engine to North America.
