No matter which B-Class model you drive, you will always be making a valuable contribution to protecting the environment. The B 180 NGT BlueEFFICIENCY, for example, can run on petrol or natural gas. And in the B 160 BlueEFFICIENCY[1] and B 180 BlueEFFICIENCY[1] models, the ECO start/stop function helps to save fuel at traffic lights or in traffic jams.

In the diesel engines, common-rail technology ensures both high torque and low consumption. The common rail keeps the fuel at a permanently high pressure throughout the engine speed range and injects finely atomised, precisely metered quantities of fuel into the combustion chambers. The result is a reduction in fuel consumption and lower pollutant emissions.
