AM General is an American heavy vehicle manufacturer based in South Bend, Indiana. It is best known for the civilian Hummer and the military Humvee, that is assembled in Mishawaka, Indiana.For a relatively brief period, 1974–1979, the company also manufactured transit buses, making more than 5,400. AM General traces its roots to the Standard Wheel Company of Terre Haute, Indiana, which expanded in 1903 to include the Overland Automotive Division. In 1908, John North Willys purchased the Overland company, then based in Indianapolis, Indiana, and renamed it Willys-Overland Motors, Inc. In the 1940s, Willys-Overland developed a vehicle to U.S. Armys requirements and later mass-produced "Americas first four-wheel drive one-fourth-ton tactical utility truck"—the Jeep of World War II fame.[dubious – discuss] In 1953, Kaiser Motors purchased Willys-Overland, and changed the name to Kaiser-Willys Motor Company. In 1963 the companys name changed again to Kaiser-Jeep Corporation. In 1964, Kaiser-Jeep purchased the Studebaker facilities in South Bend, Indiana, and formed the Defense and Government Products Division in 1967, which after American Motors purchased Kaiser-Jeep became what is now AM General. AM Generals roots (and its location in South Bend) also lie with the "General Products Division" of Studebaker, which, along with its substantial defense contracts, was acquired by Kaiser Industries in early 1964 after Studebaker closed its U.S. auto manufacturing operations. At the time, Kaiser had been awarded a US$87 million Army truck contract, and under government pressure agreed to perform the work at the South Bend plant it had recently acquired from Studebaker. Subsequently, American Motors Corporation (AMC) purchased the Jeep Corporation from Kaiser in 1970 when Kaiser itself decided to leave the auto business. In 1971, AMC made the General Products Division of Jeep (producing military trucks, as well as contract and non-commercial vehicles) a wholly owned subsidiary and renamed it AM General Corporation.
