The Chevrolet Delray, named after the Delray neighborhood of Detroit, Michigan, debuted in 1954 as an optional trim level on two-door models of Chevrolet's mid-range 210 series of cars. In 1958, it became a distinct series of its own at the bottom of Chevrolet’s lineup (replacing the discontinued 150), and added a four-door sedan, and sedan delivery, but it only remained in production for that model year. First generation (1954) The first year for Delray was the final year for the 1949-1954 style Chevrolets. For 1954 the 210 series was shortened considerably, losing its hardtop coupe and convertible but adding the Delray club coupe. 1954 The chassis and mechanical parts were common with the rest of the passenger car range, and the overall appearance was the same as the rest of the range. Front suspension was independent, named "knee-action". This year marked the end of the "Blue Flame" straight-six engine as the top engine before the introduction of the small block V8 in 1955; and 1954 was also the last year for six-volt electrical systems in Chevrolet vehicles. Engines Two engines were used in the 1954 model year, with the more powerful Blue Flame unit used with the Powerglide automatic transmission. All 210s had a three-speed synchromesh manual transmission as standard, with two optional transmissions. All engines were of an overhead valve (OHV) design. They are commonly referred to as "stovebolt sixes" because of the large slotted-head screws used to fasten the valve cover and pushrod covers to the block. 235 in³ "Blue Flame" I6 rated at on manual transmission equipped cars. 235 in³ "Blue Flame" I6 rated at on automatic transmission equipped cars. Second generation (1955–1957) For the Tri-Five years the Delray was essentially an interior option package for the plain 210 two door sedan. It featured an upgraded vinyl upholstery with "waffle-like" pleating, color-keyed to the exterior, along with carpeting and other minor upgrades. 1955 The 1955 model year marked the introduction of a new chassis and the debut of the Chevrolet's well-received small block V8. The center door frame was strengthened for more safety. Brakes were drums. A 210 buyer was free to choose any Chevrolet powertrain option. The ammeter and oil pressure gauges were changed to warning lights.
