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.
