The Chevrolet Bel Air is a full-size automobile produced by Chevrolet for the 19501981 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 1961, Chevrolet again had a totally new body, not just new sheetmetal. Its wheelbase remained 119 in (3,000 mm), but its length was now reduced slightly to 209.3 in (5,320 mm). All engines options of the previous year remained in effect with the standard engines being the 235.5 CID Six of 135 hp (101 kW) or the 283 CID V8 of 170 hp (130 kW). The V8 cost $110 more than the Six and weighed 5 lb (2.3 kg) less.
The Bel Air 2-door sedan used squared-off roof styling and large wrap-around rear window as opposed to the hardtop's swept-back design. The Bel Air 4-door Sport Hardtop still used a different roof line than did the 4-door sedan.
