Plymouth Belvedere is a series of American automobile models made by Plymouth from 1954 until 1970. The Belvedere name was first used for a new hardtop body style in the Plymouth Cranbrook line for the 1951 model year. In 1954 the Belvedere replaced the Cranbrook as the top trim and became a full model line with sedans, station wagons, and convertible body styles. The Belvedere continued as Plymouth's full-sized car until 1965, when it became an intermediate, and was replaced after the 1970 model year by the Satellite, a name originally used for the top-trim level Belvederes. The nameplate "belvedere" is Italian for "beautiful sight" or “fair view”. Chrysler also had the Belvidere Assembly Plant in Belvidere, Illinois which began production in 1965. Cranbrook Belvedere 1951–1953 Introduced on March 31, the 1951 Plymouth Cranbrook Belvedere is a two-door pillarless hardtop. It was Plymouth's first such body design and was introduced in response to the 1950 Chevrolet Bel Air, and the Ford Victoria, the first two-door hardtop in the low-priced American market. The Cranbook Belvedere was the name for the two-door hardtop version of the Cranbrook and built on the same wheelbase. Powering the Belvedere is the Chrysler flathead straight-6 engine with a 7.00:1 compression ratio producing (SAE gross). For 1952, Plymouth kept the Cranbrook Belvedere largely unchanged. The biggest alteration was to the color scheme; to further distinguish the top-level Belvedere from other Plymouths, the two tones now flowed from the roof over the beltline onto the trunk, which has been referred to as the "saddleback" treatment. Two-tone color schemes were "sable bronze" over suede, black over "mint green", and gray over blue. Overdrive was made available as optional equipment in the 1952 Plymouth. In overdrive, the engine made three revolutions for each rear wheel revolution and four without overdrive. The engine was a complete carryover from 1951. Production for 1951 and 1952 totaled 51,266 units. The Belvedere remained a part of the Cranbrook series through the 1953 model year, which saw all Plymouth models completely restyled. Major style changes include a shorter wheelbase, a one-piece windshield, flush rear fenders, and a lower hood line. In April 1953, Plymouths received the Hy-Drive semi-automatic transmission. The engine was carried over from 1952 with the only enhancement being a slight increase in the compression ratio to 7.10:1, which yielded a rating of . A total of 35,185 Belvederes were sold in 1953.
