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.
In 1957 engine displacement grew to 283 cu in (4,640 cc) with the "Super Turbo Fire V8" option producing 283 hp (211 kW) with the help of continuous (closed loop) mechanical fuel injection. These so-called "fuelie" cars are quite rare, since most Bel Airs were fitted with carburetion. The 1957 Bel Air is among the most recognizable American cars of all time; well-maintained examples, especially Sport Coupes and Convertibles are highly sought after by collectors and enthusiasts. They are roomy, with tastefully restrained, period use tail fins and chrome. A second automatic transmission, Turboglide, was optional. While the original two-speed Powerglide continued unchanged, Turboglide provided a continuously variable gear ratio which made "shifting" imperceptible. The shift quadrant on Turboglide cars followed a "P R N D Gr" pattern.[14][15]
From 1955 to 1957, production of the two-door Nomad station wagon was assigned to the Bel Air series, although its body and trim were unique to that model. Prior to becoming a regular production model, the Nomad first appeared as a Corvette-based concept vehicle in 1954. Chevrolet has since unveiled two concept cars bearing the Nomad name, most recently in 1999. The 1955–1957 Chevrolets are commonly referred to as TriFives.
The 1955-1957s were made in right-hand drive and shipped from Oshawa, Canada, for local assembly in Australia (CKD), New Zealand (SKD), and South Africa. All three model years had a reversed version of the '55 LHD dashboard and did not get the LHD models' 1957 redesign.
