The third generation of V6-diesel production Mercedes-Benz OM441 engine is presented, developing 200 kW (269 HP).


These motors are designed to meet the requirements of environmental standards Euro II. OM441 engines are very popular and widely used since the early 1990s in road engineering and medium trucks. OM441 is also used in combine harvesters, in particular, it sets in motion a combine harvester CLAAS Dominator 118 SL MAXI.
