evaporative canister to reduce emissions, and a slightly lower 8.3:1 compression ratio. During mid-year, the compression ratio was lowered even more to 7.6:1. Nevertheless, the engines continued to be rated at 170 hp. VAM American The introduction of the Gremlin line by VAM in 1974, became the company's smallest and most affordable model. There was a gap between the lower-end Rambler American line and the larger, top Classic (Matador) line. The difference in size and engine series between the Rambler American and the Gremlin was not enough for VAM to create the impression of a more solid and more diverse product line since both cars were perceived as belonging to the same economy class, which would produce internal competition. The VAM Rambler American was restricted to the economy segment since its introduction to the Mexican market, the only exceptions to this being the luxury limited edition Rambler American Hardtop (Rambler American 440H in the US) for 1963 and 1965, as well as the sporty Rambler American Rally (Rambler American Rogue and Hornet Rallye X/Hornet X in the US) from 1969 through 1974.

The Hornet-based Rambler American had been on the market for five years and saw continued sales and a positive image. The name was simplified from Rambler American to just American, marking the discontinuation of the Rambler brand in Mexico. A new luxury American ECD trim level was followed by a revised and improved American Rally and American base models. These differentiated the line from the Gremlin. All versions obtained updates and upgrades. 1975 The American base model in its first year was characterized by incorporating all-new rectangular amber parking lights, a grille divided into six squared portions, and more hexagonal-lined headlight bezels. Manual front disk brakes were standard (although a few units with the manual transmission still had front drums installed) and the I6 engine featured Prestolite electronic ignition. This engine was carried over with a 7.6:1 compression ratio, 266-degree camshaft, , and a single-barrel Carter YF or RBS carburetor. Interiors included new door panels available in either a solid color or two-tone alongside new seat patterns. The two-tone dashboard was replaced by a color-keyed unit with a new "American" emblem on the glove box door and a
