The Unimog 404 is a small four-wheel offroad capable truck designed for a payload of 1,500 kg (3,307 lb).
Like other Unimogs, it has a ladder frame, two portal axles with reduction gears and coil springs with hydraulic shock absorbers for the rear and front axle.
All four wheels and tyres have the same size and are fitted with hydraulic ATE drum brakes.
The 404 is a rear-wheel-drive vehicle with switchable all-wheel-drive and additional differential locks.

A water-cooled straight-six Otto engine, type M 180 II-U, displacing 2,195 cc (134 cu in) powers the 404.1.
It is fitted with a Zenith 32 NDIX offroad-carburettor and transmits the torque to a fully synchronised manual Daimler-Benz-six-speed-gearbox with two additional reverse gears.
As clutch, the Fichtel & Sachs K 16 Z single-disc-dry-clutch is used.

The 404 was available both with a standard closed two-door-cab and as a two-door-cabriolet with a convertible top.
The 404.1 has a divided windscreen, while the 404.0 with the cab of the Unimog model 406 has a single windscreen.
Only the standard cab models have side windows in the doors.
Special purpose vehicles, such as fire engines, were also made with an extended four-door-cab.
