The Austin Champ was a military and civilian jeep-like vehicle made by the Austin Motor Company in the 1950s. The army version was officially known as “Truck, 1/4 ton, CT, 4×4, Cargo & FFW, Austin Mk.1”, but the civilian name “Champ” was universally applied to it. The majority went to the British Army.

History of the Austin Champ
A British Army specification for a light truck was issued in the late 1940s, inspired by the Willys MB “Jeep” but able to perform in all theatres of operation. It was considered important that a British-made vehicle be produced to reduce reliance on American vehicles. A project to design a “Car 4×4 5 cwt FV1800-Series” was launched in 1947, and the Nuffield Organization built three prototypes known as the “Nuffield Gutty”; testing revealed serious shortcomings, and a team at the Fighting Vehicles Research and Development Establishment under Charles William “Rex” Sewell improved the design. The suspension was designed by Alec Issigonis, later of the Morris Minor and the Mini.

About 30 prototypes of the improved vehicle were built by Wolseley under the name “Wolseley Mudlark”, and the design was formalised as FV1801(a). Austin was awarded the contract for 15,000 vehicles, and a former aircraft factory at Cofton Hackett, next to the Longbridge plant, was fitted out for the work. The first production vehicle was completed on 1 September 1951.
Engine and versions
The Rolls-Royce-designed B40 four-cylinder engine of 2,838 cc was fitted, the smallest of the standardised B-Range engines. Approximately half of the contract was basic Cargo trucks and the rest were fitted with high-output generators and extra batteries to power radio equipment, known as “Fitted For Wireless” (FFW). Rolls-Royce built the engines for early vehicles; later ones used a virtually identical engine built under licence by Austin.
