1964. Typhoon American Motors unveiled the Typhoon in April 1964. This mid-1964 model year introduction was a sporty variant of the Classic 770 2-door hardtop. This special model was introduced to highlight AMC's completely new short-stroke, seven main bearing, 8.5:1 compression ratio "Typhoon" modern era inline-6. Production of this commemorative model was limited to 2,520 units and it was only available in a two-tone Solar Yellow body with a Classic Black roof, and a sporty all-vinyl interior for US$2,509. The car also featured a distinctive "Typhoon" script in place of the usual "Classic" name insignia, as well as a unique grille with blackout accents. All other AMC options (except engine choices and colors) were available on the Typhoon. The engine became the mainstay six-cylinder engine for AMC and Jeep vehicles. It was produced, albeit in a modified form, up until 2006. The 232 I6 engine's name was soon changed to "Torque Command", with Typhoon to describe AMC's new line of V8s introduced in 1966.

The show car was based on the top-of-the-line Classic Cross Country station wagon finished in white highlighting its full-length gold-tone anodized aluminum trim along the upper part of the bodysides (replacing the side spear that was standard on 770 models) as well as matching gold trim on the lower part of the tailgate between the tail-lights. This was one of AMC's concepts displayed at the Chicago Show that included the Rambler Tarpon fastback and the Rambler Carrousel convertible, but the Cheyenne was likely most significant because AMC "did lots of specially trimmed, production-based show cars in its day" given the large number of station wagon models it sold. Third generation The 1965 model year Classics underwent a major redesign of the new platform that was introduced in 1963; essentially the 1963–1964 design with a rectilinear reskin similar to that of concurrent Ambassadors. Fresh sheet metal design was applied to the original wheelbase and long integral body-frame with only the roof, doors, and windshield as carryovers. Unchanged was the suspension system including a torque tube with coil springs with a Panhard rod. The Rambler Classic was now shorter than – as well as visually distinctive from – the Ambassador line, while still sharing the basic body structure from the windshield back. For the
