M151 MUTT.

The US Army’s quarter-ton of 1959–82, designed by Ford from 1951 as the M38A1’s successor: a unibody with independent suspension all round, the 2.3-litre Ford four and an 85-inch wheelbase, built by Ford, Kaiser Jeep and AM General — more than 100,000 for over 100 countries, until the Humvee replaced it from 1985.

The record

Ford won the 1951 development contract for a lighter, roomier quarter-ton and produced the M151 for 1959 with a monocoque hull, coil-sprung independent suspension and the 71 hp Ford four. The swing-axle rear made the early M151 and M151A1 (1964) prone to rollover; the M151A2 of 1968 fitted semi-trailing arms. Variants included the M718 ambulance, the M825 with the 106 mm recoilless rifle and the M151A2 TOW carrier. Ford, Kaiser Jeep and AM General built it; the Army withheld it from civilian sale and scrapped or cut most of its own, while foreign users ran it into the 2000s.

AI rendering impression

An AI rendering impression starts from a 3D model of this vehicle, which an image model then paints into a scene. It is an artist's impression of the type, made to give a feel for the vehicle in its element — not a photograph, and not a record of any particular vehicle.

Proportions, fittings, markings, colours and the setting can all drift from the original in the process. For the vehicle's actual details, rely on the specification, the photographs and the cited sources on this page.
