Duesenberg Model A

The Duesenberg Model A was a large straight eight powered luxury car produced between 1921–1926 by the American automobile manufacturer Dusenberg. Officially known as the Duesenberg Straight Eight, the rear wheel drive Model A was first shown in late 1920 in New York City. Production was delayed by substantial changes to the design of the car, including a change in the engine valvetrain from horizontal overhead valves to an overhead camshaft; also during this time, the company had moved its headquarters and factory from New Jersey to Indiana. The Model A was manufactured in Indianapolis, Indiana, from 1921 to 1925 by the Duesenberg Automobiles and Motors Company and from 1925 to 1926 at the same factory by the restructured Duesenberg Motor Company. The successors to the company began referring to the car as the Model A when the Model J was introduced. The Model A was the first automobile in series production to have hydraulic brakes and the first automobile in series production in the United States with a straight-eight engine. It was produced as a rolling chassis and received a wide variety of coachbuilt body styles, and was succeeded by the Duesenberg Model X.
