1975 Monte Carlo
Personalized Luxury was the concept behind the all-new 1970 Monte Carlo. GM’s success with Buick’s Riviera, Oldsmobile’s Toronado, and Pontiac’s Grand Prix meant it was only a matter of time before Chevrolet also entered the field, and Chevy did in a big way. Based on the GM A-body platform, the engineers and designers created the “A-body Special” chassis which extended the wheelbase ahead of the firewall from a standard Chevelle or LeMans. This created a longer hood to proportion the Monte Carlo more elegantly. The chassis was later named “G-body” denoting the 4-inch longer wheelbase from a standard Chevelle 2-door. 1970-72 Monte Carlos are similar, featuring only minor trim and detail differences. Completely redesigned in 1973, this more baroque, “neo-classic” Monte received only minor trim and interior changes through 1977. The 1978 Monte Carlo was downsized along with its sister A-body Chevys, trimming 800-pounds and 15-inches from its 1973-77 incarnations. It retained this basic styling through 1980. In 1981 the fourth-generation Monte Carlo was introduced, refining and enlarging the earlier model’s styling. It remained the same through 1988, with an added Aerocoupe model featuring a fastback rear window to better compete in NASCAR, appearing in 1984. This body style soldiered-on through 1988, which was the last year for the Monte Carlo until the model was revised in 1994.
1975 Monte Carlo
A new grille and vertical taillights were the main changes from 1974. High energy electronic ignitions (HEI) and catalytic converters were new features, which also meant Monte Carlos would need to run on unleaded gas. New cloth interiors and all-white vinyl interiors were added. A three-speed manual transmission was listed as standard with the base 350ci engine, but tribal knowledge indicates all Montes were manufactured with automatic transmissions.
