The AMC AMX was a two-seat GT-style muscle car produced by American Motors Corporation from 1968 through 1970. It was based on the Javelin, but with a shorter wheelbase and deletion of the rear seat, and was in direct competition with the Chevrolet Corvette for substantially less money. The AMX was fitted with the standard high-compression 290 cu in (4.8 L) or optional 390 cu in (6.4 L) AMC V8 engine, offering top-notch performance at an affordable price. Although sales never thrived, AMC's larger objectives to refocus its image on performance and bring in younger customers were achieved. After three model years, the two-seat version was discontinued, and the AMX badging was transferred to a high-performance version of its four-seat sibling, the Javelin.
