Rally was the first unit of its series to offer the original factory air conditioning system as an option. The hood and trunk lights as well as the glove box unit were added to the standard equipment list. The Rally included D70x14 radial tires in all years and rear gear ratios of 3.54:1 (1970–1972), 3.31:1 (1973–1976), and 3.07:1 (1977). The American Rally was discontinued in 1977 along with all other Hornet-based VAM Americans. It would find a successor in the 1978 American Rally AMX model (VAM's version of the 1978 AMC Concord AMX), meaning the production in Mexico for the first time of AMC's hatchback coupe body style. Unlike the AMC Hornet X models, both the Hornet-based Rambler American Rally and American Rally were never available with V8 engines, automatic transmissions, or column-mounted shifters. The Rally model was more than just an appearance package, but was also not as strong as a muscle car finds its closest American equivalent in the form of the 1972 Hornet Rallye-X model. It is regarded as one of VAM's most collectible and sought-after models. American ECD As part of the shift in market strategy for VAM's Hornet-based compacts for 1975 that included advancements in the American base model and American Rally was the introduction of the new American ECD or Edición Cantos Dorados (Golden Edges Edition). It represented for the first time a VAM four-door compact was not an economy base model. The American ECD was VAM's first regular production luxury compact as previously it was only a limited edition of the two-door hardtop in 1963 and 1965 as the Rambler American Hardtop (equivalent to the Rambler American 440H in the US and Canada). The ECD was restricted to the four-door sedan while the 1975 American Rally was the high-trim two-door sedan. The station wagon remained a single-edition model. The American ECD was equivalent in the U.S. to the 1975 four-door Hornet DL model. The 1975 American ECD came standard with a 170 gross hp I6 engine with a single-barrel Carter carburetor, electronic ignition, 266-degree camshaft, and 7.6:1 compression ratio with a regular cooling system. Included were manual front disk brakes with rear drums, power steering, heavy-duty suspension with front sway bar, Chrysler TorqueFlite A904 three-speed automatic transmission, and a 3.31:1 rear gear ratio. The exterior of the model incorporated a full vinyl roof with bright moldings, regular bright molding package (wheel lip, rocker
