ザ Chevrolet Deluxe was a trim line of Chevrolet automobiles, marketed from 1941 to 1952, and was the volume sales leader for the marque during the 1940s. The line included, at first a 4-door sedan, but grew to include a fastback 2-door “aerosedan” and other body styles.
The original series ran from 1941 to 1948, after which a new body style was introduced for 1949, running through 1952.
During the post-war years and continuing through the early 1950s, the Deluxe range was Chevrolet’s sales leader, offering a balance of style and luxury appointments unavailable in the base Special series; and a wider range of body styles, including a convertible, Sport Coupe hardtop (starting in 1950), two- and four-door sedans and four-door station wagons.
The 1941 Chevrolet was the first generation that didn’t share a common appearance with Chevrolet trucks, while the Chevrolet AK Series truck did share common internal components.
