the 1960s. Together with Brooks Stevens, Teague presented ideas about future cars and vehicle technologies at the 1963 SAE congress in Detroit. Teague, "who is generally considered to have been a bit of a maverick" predicted an evolutionary process for automobiles that turned out to be right. Teague foretold improvements in conventional gasoline engines, while cars "would have greater variety of style now that glass could be shaped, and better suspension systems" In contrast to Stevens, Teague believed that the automobiles of 1970 would still be built to provide basic transportation, and not be "a home on wheels" powered by an advanced power plant “the size of a breadbox.” During the early-1960s, Teague's styling team began developing an entirely new concept for AMC - a sporty fastback design. Teague knew that the automaker was just not willing to spend the millions of dollars needed for all-new tooling, his design team made imaginative use of existing tooling and create spin-offs from existing products. The results were proposals for which Teague selected the names for both: the Tarpon show car and the production Marlin. Although promoting the smaller version, Teague recalled that "Abernethy had decided that instead of a 2+2 we would build a 3+3 sports-type car." Teague was responsible for the design of several AMC and Jeep vehicles. He developed the Gremlin, Pacer, Matador coupe, Rambler American, AMC Javelin, and AMX Hornet, and subsequently adapted AMC's compact platform for the Concord, Spirit and Eagle models. He was also responsible for a number of concept cars and lobbied for the production of several, including the compact Tarpon that ultimately led to the large Marlin. He also lobbied for continuing the two-seat AMX models after 1970. The 1968 AMX GT was one of the Teague-designed concept cars which had some of their design elements incorporated into production models. For this short-wheelbase coupe he styled a truncated kammback tail which was then used on the 1970 Gremlin. He also designed the "Concept 80" series of show cars, built on variations of existing AMC platforms as ideas for possible future models. Perhaps Teague's strongest effort ever was the "handsome design" of the 1970 AMX/3 that AMC developed with help on the chassis from Italian sports-car engineer Giotto Bizzarrini and road testing and development from BMW. Before he and his team of designers settled on the final design, a fiberglass pushmobile was made with the molds
