The best-selling U.S. car was a competitively priced, pre-war-styled machine whose Stovebolt Six engine dated back to 1937. Nineteen-forty-six Chevrolet models arrived late in 1945 and received changes typical to General Motors' and other manufacturers' lines. A new grille featuring four horizontal bars under a top bar that curved down at each end to form a simple yet pleasing grille design was the primary change.
Rectangular parking lights were relocated to each end of the grille and a new hood ornament was placed on the front of the hood. A decorative stainless steel trim piece ran front to back at door handle level on the bodyside of all models, except the Station Wagon, which was still wood bodied. Fleetmaster Fleetline models sported three chrome strips behind each wheel opening for added distinction. Front and rear bumpers, advertised as "Car-Saver" bumpers, were redesigned to provide more protection, including a slight wraparound at the ends and a barely noticeable "V" point. Otherwise styling continued as on prewar cars, including "Modern, Door-Action Fenders" (the front fenders extending onto the front doors).
The 1942 sub-series nameplates were promoted. Stylemaster replaced the Master DeLuxe Stylemaster, and Fleetmaster replaced the Special DeLuxe Fleetmaster. Technically the Fleetline models were the top line Chevrolets, but they were a sub-series of the Fleetmaster series, and therefore are included with the parent series in the listings below, as most important features were shared. The Fleetline model numbers are also numbered within the Fleetmaster series. Otherwise, the GM A-body Chevys continued with few changes from the 1942 models.
