1958 Chevrolet Impala Convertible (more pics below 👇)
Chevrolet’s 1958 model year brought the Impala name into production for the first time, offered exclusively as a convertible or two-door hardtop within the Bel Air lineup.
The car made an immediate visual impression: six taillights across the rear, chrome air scoops ahead of the rear wheels on the fenders, spinner hubcaps, and crossed-flag insignias set it apart from every other Chevrolet at a glance.
An all-new X-frame chassis allowed the body to sit longer, lower, and wider than previous Chevrolet models. The 348ci V8 was Chevy’s first big-block engine in a passenger car, available in several states of tune.
In “Super Turbo-Thrust” Tri-Power form, fed by three two-barrel carburetors, output reached 280 horsepower, while higher-output versions were rated up to 315 horsepower.
A 235ci six and multiple 283ci V8 configurations rounded out the engine choices. Transmission options included a three-speed manual with overdrive, as well as Powerglide and Turboglide automatics.
The convertible was the most expensive Chevrolet passenger car available that year, with production of 17,778 units (compared to 55,989 hardtops). The Anniversary Gold color option was specific to 1958, offered to mark Chevrolet’s 50th anniversary year.
