The Chevrolet Bel Air was a full-size automobile that was produced by Chevrolet for the 1950–1981 model years. Initially only the two door hardtops in the Chevrolet model range were designated with the Bel Air name from 1950 to 1952, as distinct from the Styleline and Fleetline models for the remainder of the range. With the 1953 model year the Bel Air name was changed from a designation for a unique body shape to a premium level of trim applied across a number of body styles. The Bel Air continued with various other trim level designations until US production ceased in 1975, production continued in Canada for its home market only through the 1981 model year.
For 1965, the full size Chevrolet was totally restyled, and the cars were stretched to 213.3 in (5,420 mm) overall, even though the wheelbase remained the same. The new stamped grille had a lower extension below the bumper which was slightly veed. Curved window glass and round taillights mounted high characterized the new styling. The interiors were also redesigned and a very attractive dash resulted. The standard V8 remained the 283 CID model of 195 hp (145 kW), but options included two new 396 cu in (6,490 cc) CID engines of 325 and 340 hp (250 kW) and two 409 CID blocks of 400 and 425 hp (317 kW).
The Bel Air utilizes a stainless-steel belt and rocker molding, identifying signature on the rear fenders, a glove compartment light and power tailgate on 9-passenger wagons to distinguish itself from the lower-priced Biscayne series.
For 1967, Full-sized Chevrolets featured a new body with bulging rear fenders, one of this year's styling trends, not necessarily appreciated by everyone. Bel Air 2 and 4-door Sedans continued in addition to 6 and 9-passenger wagons. This year Bel Air featured triple taillights unlike Biscayne's dual units. Standard engines remained the same as the previous year. Optional engines were a 327 CID V8 of 275 hp (205 kW), the 396 CID V8 of 350 hp (260 kW); or the 427 CID V8 of 385 hp (287 kW), plus various speed packages.
The 1965-70 GM B platform is the fourth best selling automobile platform in history after the Volkswagen Beetle, Ford Model T and the Lada Riva.
