The name 'Jeep' came from a corruption of General Purpose (or 'GP') vehicle. At the beginning of the second World War the American government called for tenders to produced a small four wheel drive general purpose vehicle for military use. The contract was won by the Bantam BRC model, but the US Army Quartermaster considered that Bantam could not manufacture their Karl Probst design in sufficient quantities, so the US Army passed the design onto the other bidders Ford and Willys. 1500 Bantam BRC 40, 1500 Willys MA Quad, and 1500 Ford Government Pygmy were ordered for trials, and both Ford and Willys borrowed from the Bantam. Willys won this contest, developing its design into the Willys MB, and being awarded a contract for 16,000 vehicles in July 1941. By October 1941 Ford was asked to also manufacture the Willys MB as the Ford GPW and both cars had only minor differences. 350,000 Willys MB were manufactured and 280,000 Ford GPW. Willys brought out a civilian version of the MB as the CJ-2A from 1945-49, and the CJ-3A Universal from 1949-53. A military version of the CJ-3A was used in the Korean War as the Willys MC or M38 from 1950-52. This was followed by the launch of the M38-A1 using a new 2199cc F-head Hurricane engine which continued in military use until 1971. Kaiser-Frazer bought out Willys Overland in 1953, renaming it 'Willys Motors'The CJ5 was introduced in 1955 under Kaiser Industries ownership and could be ordered with the 3.68litre V6 Buick Dauntless engine, and this model continued in production until 1983.
