The Chevrolet Series AA Capitol was a car that was the only car made by Chevrolet for the 1927 model year and the successor of the Superior Series V.

The vehicle was introduced in January 1927 and was available with eight different bodies which included a two-seater roadster, two-seater coupe, two or four-seater sports convertible (coupe with hardtop) and five-seater sedan (with two doors). With four doors, there was the five-passenger touring car and the five-seat sedan.

The car had a top-driven four-cylinder inline engine (OHV). The engine with 2802cc displacement developed 26bhp (19 kW) at 2,000rpm. The engine power was transmitted via a single dry clutch and a manual three-speed gearbox to the rear wheels. The rear wheels were fitted with external band brakes.

The prices for a Capitol were between $525 and $745 (depending on the model). After a year in production 1,001,820 vehicles had been made and the model was succeeded by the National Series AB.
