== Series numbers and models ==
Unimog series numbers like 401, 406, or 425 in this article are the factory numerical designation (in German "Baumuster", literally ''Construction Pattern''). Unimogs also have a sales model number like U 80, U 120, or U 1350. Each series can have several model numbers, as they are equipped with different engines or chassis options.

Originally, the "U" model numbers were roughly equivalent to the horsepower of the engine (in German: PS):
* A 424.121 with a {{Convert|2630|mm|in|frac=8|abbr=on}} wheelbase equipped with the {{Convert|100|PS|kW hp|abbr=on|lk=on}} OM 352 engine is a U 1000
* A 427.100 with a {{Convert|2650|mm|in|frac=8|abbr=on}} wheelbase and the 100-PS 366 engines is also a U 1000.

Starting in 1976, model numbers added an extra 0 at the end.  More recent model numbers may have three or four digits and sometimes do not relate to horsepower (the engine of the U 5000 is rated at 218&nbsp;PS).  The most recent models introduced since 2013 are:
* The 437.4 series is intended for extreme offroad use, with the smaller U 4023 and larger U 5023 models, which are only available with 230&nbsp;PS engines
* The 405 series is intended for use with implements, with three digit model numbers.  The first digit is related to the vehicle size (U 200, U 300, U400 and U 500 model ranges) and the second and third digits related to the engine power, starting from the 190&nbsp;PS U 219 and going up to the 350&nbsp;PS U 535.
