The OM 326 engine is a non-turbocharged, 6-cylinder, 4-stroke, pre-chamber, water-cooled, OHV diesel engine.

The arrangement of the cylinders is in-line, as in all engines of the OM 300 series. The engine has 10.8 liters and develops 200 hp (147 kW). The mass of the engine, depending on the modification, is 770-780 kg. It is used on trucks, mainly Mercedes-Benz O 317. Around 1970, the engines began to be replaced by the newly developed OM 400 series, but it was not until 1978 that they finally ceased production.
