The Chevrolet Series AB National (or Chevrolet National) is an American vehicle manufactured by Chevrolet in 1928 to replace the 1927 Series AA Capitol. Documented production numbers show that 1,193,212 Series ABs were manufactured in a variety of body styles with 69,217 originating from the Oshawa factory alone.^[1] Chevrolet instituted serial number recorded on the front seat heel board on either the left or right side, using the listed numbers to designate the point of origin of the vehicle identified.

Specification

Looking very similar to the 1927 Series AA Capitol, the wheelbase of the Series AB was increased by four inches to 107 in (2,718 mm). The updated look was one of the first projects from GM's Art & Colour studio.^[3] It was the last Chevrolet to use a four-cylinder engine until 1961 and the Chevrolet Chevy II / Nova. Roadsters and touring sedans had the ability to fold the windshield forward on top of the cowl for open air driving.^[1]

The Series AB was powered by Chevrolet's old 171 cu in (2,800 cc) four-cylinder engine, but with minor modifications to produce 35 hp (26 kW) at 2,200 rpm. Four-wheel braking was also now provided. Fisher Body provided eight different coachwork choices to include both open and closed body styles. The top choice was listed as the Imperial Landau listed at US$715 ($12,687 in 2023 dollars ^[4]).^[1] In May 1925 the Chevrolet Export Boxing plant at Bloomfield, New Jersey was repurposed from a previous owner where Knock-down kits for Chevrolet, Oakland, Oldsmobile, Buick and Cadillac passenger cars, and both Chevrolet and G. M. C. truck parts are crated and shipped by railroad to the docks at Weehawken, New Jersey for overseas GM assembly factories.^[1]
