The Mercedes-Benz OM654 is a family of inline-four cylinder automobile diesel engines introduced by Mercedes-Benz in 2016. The engine is a 2.0 litres (1,950 cc) turbo-diesel cast aluminum block in line four-cylinder with balancing shafts. It has a single turbo and cylinder walls are lined with slippery Nanoslide, an iron-carbon coating that cuts friction. In the 220-configuration it produces 143 kW (194 PS; 192 hp) at 3,800 rpm with peak torque of 400 N·m (295 lbf·ft) at 1,600-2,400 rpm. The engine weight is 168.4 kg (371 lb) (a 17% improvement over the 202.8 kg (447 lb) of the previous 2.1 litres (2,143 cc) OM651). Also, the engine consumes 13% less fuel than its predecessor. It is planned that it will feature across the entire Mercedes-Benz range of cars and vans.
