The OM 4xx series was a family of Daimler-Benz diesel engines, mostly in V layout and mostly for commercial vehicles, that replaced and supplemented the large inline six-cylinder engines of the OM 300 series. The first generation, the OM 40x, was presented at the 1969 IAA and delivered from 1970. It was built as a modular system of 90 degree V engines with 6, 8, 10 or 12 cylinders, all with a bore of 125 mm, and two inline engines with five and six cylinders were added, apparently for buses. The ten-cylinder OM 403 weighed only 910 kg and reached a specific fuel consumption of 223 g/kWh. Daimler-Benz developed the engines together with MAN, which kept its own combustion process. The OM 42x of 1980 widened the bore to 128 mm, the OM 44x of 1985 added electronic diesel control, and from 1996 the OM 50x began to take over.
