A six-speed manual transmission is standard on the four-cylinder models, the E 200 CGI BlueEFFICIENCY[1], E 200 CDI BlueEFFICIENCY[1], E 220 CDI BlueEFFICIENCY and E 250 CDI BlueEFFICIENCY. The short-throw action and optimum matching of engine power, transmission ratios and final drive ratio provide optimum conditions for sporty yet fuel-efficient driving. In addition, a display in the instrument cluster supports a particularly thrifty driving mode.
