Standard on all body styles except the convertible was the "Powerflow 6" L-head engine. The convertible was only V8 powered and V8s were available in other Belvederes with an optional "Fury" version as well as a "High-Performance PowerPAC" at extra cost. A manual transmission was standard with the push-button two-speed PowerFlite optional and the push-button three-speed TorqueFlite automatic also optional on V8 cars. The front suspension introduced Chrysler's Torsion-Aire Torsion bar suspension shared with all Chrysler products starting in 1957. In 1957, Chrysler products offered an appearance of either single or dual headlights. Plymouth installed the headlights in a facia that accommodated dual headlights while offering both single and dual lamps. This appearance can be seen with front turn signal lamps installed inboard, next to the headlight, while vehicles installed with dual headlights offered a concealed turn signal above the headlights in the headlight alcove. The Belvedere would once again return as a top-level trim for 1958 for the last time. Styling was a continuation of the 1957 models. A big block "B" engine of 350 in3 V8 with dual four-barrel carburetors dubbed "Golden Commando" was optional on all models. For 1959, the Fury became the top range with a full array of sedans and coupes, and the Belvedere became the middle range. The Savoy became the least expensive model, and the Plaza was discontinued. The convertible was only available in the Belvedere model between 1956 and 1958. The 1957-58 Belvedere two-door hardtop gained notoriety from the movie Christine (1983) based on the novel by Stephen King. In the opening scene, in which the titles set as "Detroit, 1957", Christine appears near the end of the assembly line as a lone bright red car in a long line of Buckskin Beige Furys being built for the new model year (1958). (In the novel it is revealed that her first owner, Roland Lebay had ordered her with custom paint, as the standard 1958 Fury came only in beige.) For the movie, Christine was painted "toreador red" with an "iceberg white" top. 1960–1961 Starting in 1960, Belvederes got a brand-new standard inline six-cylinder engine replacing the venerable valve-in-block "flathead" six. Colloquially known as the Slant Six, it displaced , featured overhead valves, and a block that was inclined 30 degrees to the right to permit a lower hood line with maximum displacement. This engine used a single-barrel Holley carburetor, and became known
