After a management change at AMC, Teague worked under Roy D. Chapin, Jr. who was also a sports car enthusiast. 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 1966. Other top executives, such as Robert B. Evans, wanted Teague's two-seat AMX design to be brought to the market "very quickly." Teague originated a non-running show car in late-1965 and since he was a “two-seater kind of guy, the production American Motors AMX was his car." The new models offerings reflected AMC's strategy to shed its "economy car" image and appeal to a more youthful, performance-oriented market.
