Description
The Jeep Willys Overland MB, often referred to simply as the Willys MB, was a light military utility vehicle produced during World War II. It became an icon of rugged, all-terrain capability and was widely used by the U.S. Army and Allied forces. The vehicle was developed by Willys-Overland in collaboration with Ford, under government specifications for a compact, lightweight, four-wheel-drive vehicle suitable for reconnaissance and transport on rough terrain.
The Willys MB was powered by a 2.2-liter “Go-Devil” inline-four engine, producing about 60 horsepower. This engine, combined with the MB’s compact design and durable construction, allowed it to tackle challenging terrain with ease. The vehicle featured a three-speed manual transmission and part-time four-wheel drive, enabling versatile performance both on and off-road.
Production of the Willys MB began in 1941 and continued until the end of the war in 1945, with over 360,000 units produced by Willys-Overland and an additional 280,000 produced under license by Ford as the GPW. Its simplicity, reliability, and adaptability led to widespread success on the battlefield, where it was used for a variety of roles, from troop transport to medical evacuation.
The Willys MB was instrumental in setting the standard for military and civilian off-road vehicles, and its design influenced the post-war Jeep CJ series, which helped establish the Jeep brand. Its legacy endures in modern Jeep models, with the MB often seen as the vehicle that sparked the Jeep culture and off-road movement.
