1957 Chevrolet –  Slick and Ultra-Collectible

This is one of the most popular models in the modern collector car hobby because of slick styling and crisp good looks. It would be the last year of the 115 inch wheelbase – returning in 1964 on the mid-size Chevelle.

General Year Information – 1957 Chevrolet Facts

One of the most popular models in the modern collector car hobby, the 1957 Chevrolet was highlighted by a new oval shaped front bumper grille complete with bomb type bumper guards. Round front parking lamps were seen at each end of a horizontal center bar that seemed to float against the delicately cross-hatched grille insert.

A Chevrolet medallion was set into a center cavity within this horizontal bar. Wind split bulges ran along both sides of the flat hood panel, decorated in front by bomb sight ornaments. The headlamps were set into small “grilles” housed in square-looking fender openings. New side moldings appeared, but varied for each series, looking a little richer as they moved up the scale. The rear fenders were shaped into broad, flat tail fins. The Chevrolet gas filler was incorporated into the chrome molding at the rear edge of the left-hand tail fin.

Ed Cole, the chief engineer of Chevrolet beginning in 1952, wanted Chevrolet to be the first GM brand to offer fuel injection. Much of the development of the Ramjet F.I. was done by engineer John Dolza. Dynamometer tests of a 265 CID small block with fuel injection were performed as early as 1955. In 1957, Ramjet F.I. was RPO-578 on the passenger cars.

Turboglide was a constant torque, continuously variable automatic transmission offered as an option beginning this year. It was a turbine-driven planetary gearbox with a “switch pitch” dual-pitch torque converter stator. Turboglide was modeled after the Buick Dynaflow transmission, and operated very similarly.

Series 150 I-6 & 1200 V-8. The 150 models were the plainest. They had exclusive use of the 1955-1956 style sash molding (below rear side windows), which intersected an approximately half-length. single horizontal molding. This strip of chrome ran. from the front door region, to the trailing edge of the tail fins. “Chevrolet”, in script were affixed to the upper sides of front fenders. The fins had only partial outline moldings near their rear tip, which dropped to the taillight housing. The grille insert was done in anodized aluminum finish.

Interior trims were the most basic, although the Handyman station wagon had a two-tone look inside. Round horn buttons were used, with standard steering wheels.

 

Series 210 I-6 & 1600 V-8. The 210 was distinguished from the150 series by the distinct side trim treatment and upgraded interiors. The body rub moldings began just behind the headlight area and gently sloped to the rear bumper ends, although the sweep was most pronounced towards the rear half of the body. However, there was a second, upper molding, that branched off just below (and behind) the body belt dip. This top molding just about paralleled the general contour of the fins and ran, rearward, to hit the back edge of the fender. Inside the two moldings, near the tail lamp, a “Chevrolet”, in script, was placed. With the optional two-tone finish schemes, this “inside” area was painted a contrasting color, .

Other trim features were the same as 150 models. Rear fender top moldings on the rear third of the fins only and silver aluminized grilles. Three two-tone interior schemes, with cloth and vinyl combinations, were available without charge. The Two-Ten looked more Bel Air like, especially with the optional two-tone exterior finish. As in 1956, all Chevrolets with V-8 power had large, V-shaped hood and deck lid ornaments, which were bright metal finished.

BEL AIR SERIES: 2400C I-6 & 1800 V-8. Extra richness characterized the Bel Air line in all regards. Side trim was arranged as on the 210 Series, except the area between the molding “branches” was filled with a silver anodized aluminum beauty panel. At the front, three gold chev­rons were added to the forward side of each front fender. Also done in gold were such things as the grille insert, V-8 ornaments when fitted, and “Bel Air” on the beauty panel in script. The rocker sills, roof, and window outlines and the entire edge of the fins were all trimmed with bright metal moldings. There were also traditional Chevrolet/Bel Air crests on the rear fenders, near the golden script.

Distinctive two-tone interiors were fitted to the Bel Air. The Nomad station wagon had carryover features with but with the new 1957 styling. Of course, the Bel Air convertible had all the hardtop’s features with an even more stylish interior.
