| Chronology | |
| Successor | OM605 |
The successor of the OM617 engine family was the newly developed straight-5 diesel automobile engine OM602 from Mercedes-Benz used from 1980s up to 2002. With some OM602 Powered Mercedes-Benz vehicles exceeding 500,000 or 1,000,000 miles (800,000 or 1,610,000 km),[1] it is considered to be one of the most reliable engines ever produced,[2] a success which is only comparable with the famous OM617 engine.
It is closely related to the 4 cylinder OM601 and the 6 cylinder OM603 engine families of the same era.
The 5-cylinder OM602 was succeeded by the four-valve OM605 engine and later the OM612 and OM647 engines with turbocharger and common rail direct injection.
