New Generation Of Four-Cylinder Diesel Engines From Mercedes-Benz

Stuttgart -- What better way to mark the 150th anniversary of Rudolf Diesel's birth than a brand new generation of four-cylinder diesel engines from Mercedes-Benz which outstrip all previous benchmarks for performance, torque, emission properties and, most notably, fuel economy in their segment?

New four-cylinder diesel engine from Mercedes-Benz: Engine OM651

In its most powerful variant, the new four-cylinder unit musters up 150 kW/204 hp from its 2143 cubic centimetres, meaning that it delivers around 20 per cent more power than the engine it replaces. At the same time, peak torque has risen from 400 Nm to 500 Nm, equating to an increase of 25 per cent. Despite the 25 kW increase in output, the new four-cylinder diesel burns substantially less fuel than its predecessor, which was itself highly economical. As a consequence, CO2 emissions are reduced by as much as 13 per cent and the new four-cylinder diesel unit already complies with the future EU5 emissions standard.
