Teague joined
American Motors Corporation (AMC) as a member of
Edmund E. Anderson's design team in September 1959. Teague's first assignment, according to designer James W. (Jim) Alexander, was to re-do the front sheet metal on the 1961
Ambassador. The first cars influenced by Teague's styling were the 1963
Rambler Classic and Ambassador, AMC's first all-new models since 1956. After Anderson left AMC in 1961, Teague was named the director of styling. His first significant project was the
Rambler Tarpon, a compact
fastback that could have "conceivably matched Ford's forthcoming Mustang for pace and style" if AMC's president
Roy Abernethy had approved it. Although he worked within tight budget restrictions at AMC, Teague sometimes referred to his time there as "
Camelot". Designing several different cars from existing AMC stampings, he worked "relative miracles" compared to the spending norms in this industry. With little money to work with, he reconfigured the existing cars and parts in new ways. For example, he incorporated the doors from AMC's large-sized automobiles into his design for the new 1964 compact
Rambler American. The
AMC Cavalier was one of the "Project IV" concept cars in the mid-1960s that demonstrated advanced techniques of interchangeable body panels and design
symmetry. The right front and left rear fenders were identical, as well as the panels for doors, hood, and deck lid, all interchanged. The
automobile platforms designed by Teague featured numerous interchangeable door skins, glass, and more. For example, the front and rear bumpers on the 1970 AMC Hornet were made from the same stamping. This design talent yielded significant cost savings for the company. Teague's work on the 1967 through 1969
AMC Ambassador proved that he "could do more with less than most any other car designer around—usually because he had to." While the 1965 models were reskinned and rode on a longer wheelbase, Teague "came through handsomely with crisp, angular lines" that helped the Ambassador achieve record sales. Teague developed production models that featured "excitement," such as the
Javelin. This design evolved from two AMX prototypes that were part of the "
Project IV" concept cars during the 1966 automobile show circuit. Other top executives, such as
Robert B. Evans, wanted Teague's two-seat
AMX design to be brought to the market "very quickly." The new models' offerings reflected AMC's strategy to shed its "economy car" image and appeal to a more youthful, performance-oriented market. In 1971, Teague proposed an innovative economy car incorporating a lightweight materials with front-wheel drive utilizing a compact
Wankel engine. It was also the first 'wide-small' automobile that "gave drivers the impression they were driving a conventional large American." Its "styling was different and appealing in an offbeat sort of way" featuring large amounts of glass. The company "produced some wonderfully creative and original designs". In the 1980, Teague unsuccessfully attempted to persuade AMC's board of directors with a
minivan concept, a design formula adopted by Chrysler. Teague headed talented stylists that included Fred Hudson,
Chuck Mashigan, Robert "Bob" Nixon, Vince Geraci,
Norbert Ostrowski, and others. ==Teague designs==
