It was first introduced in the facelift W222 S-Class.[1] DesignThe OM656 is based on a modular design that is shared with other 4-cylinder and 6-cylinder, petrol and diesel engines.[2] It is the replacement to the previous V6,[3] in order to maintain the cost of production between different engines. The OM656 has dual overhead camshafts with variable valve timing, and uses AdBlue injection and exhaust gas recirculation to reduce emissions.[4] The cylinder walls are coated with an iron-carbon alloy to reduce friction.[5] Models
