History of the Oldsmobile Autocrat
A middle model on Limited lines

Oldsmobile brought out the Autocrat in 1911 as the middle of its range. Apart from the engine, its engineering followed the top model, the Limited. Under the bonnet sat a side-valve four-cylinder engine of 7,718 cc that produced 40 bhp, driving the rear wheels through a leather cone clutch, a four-speed gearbox with the lever mounted outside on the right, and a propeller shaft. All four wheels had wooden spokes, and the rear wheels were braked mechanically by drums with external bands.
Two years and two series
The car was sold as a four-door tourer or saloon, or as a two-door roadster, all under the Series 28 name. For 1912 it continued almost unchanged as Series 32, the only significant difference being a wheelbase two inches longer. In 1911 Oldsmobile built 1,000 cars across the Autocrat and the smaller Special together; in 1912 the Autocrat alone accounted for 500. The model was dropped the following year without a replacement.
