The AMC AMX is a two-seat GT in style and approach sports car that was produced by American Motors Corporation for the 1968 through 1970 model years. The AMX was also classified as a muscle car, but "unique among other American cars at the time due its short wheelbase". The AMX was also the only American-built steel-bodied two-seater of its time, with the 1955-1957 Ford Thunderbirds being the last ones. To a degree, the AMX was a competitor with America's only other two-seater of the era, the Chevrolet Corvette for substantially less money. With a one-inch (2.5 cm) shorter wheelbase than the Chevrolet's 2-seater, "the AMX was often seen by the press as a Corvette competitor."
Fitted with the optional high-compression medium block 390 cu in (6.4 L) AMC V8, the AMX offered top-notch performance at an affordable price. In spite of this value and enthusiastic initial reception by automotive media and enthusiasts, sales never thrived. However, the automaker's larger objectives to refocus AMC's image on performance and to bring younger customers into its dealer showrooms was achieved. After three model years, the two-seat version was discontinued, and the AMX's now signature badging was transferred to a high-performance version of its 4-seat sibling, the Javelin, from 1971-1974.
American Motors capitalized the respected reputation of the original AMXs by reviving the model designation for performance equipped versions of the Hornet in 1977, Concord in 1978, and Spirit in 1979 and 1980.
