Brush Runabout History

Introduced in 1907 by Alanson Partridge Brush — a self-taught engineer who had already helped Henry Leland develop the original single-cylinder Cadillac — the Brush Runabout was engineered from the outset for affordability. Its chassis was built from oak, hickory, and maple with iron cross-members; the frame, axles, and wheels were all wood. A single-cylinder, water-cooled, four-stroke engine of approximately 824 cc produced six horsepower and drove through a friction-drive transmission and chain to the rear axle. The whole car sold for around $450–$500 at introduction — roughly the same price as a good horse and buggy — and was marketed nationally as the 'Everyman's Car.'

Brush's engineering choices were unconventional and shrewdly practical. The engine rotated counter-clockwise, reducing kickback injuries when hand-cranking. Coil springs were fitted at all four corners — a genuine innovation for the era — giving the light car a notably compliant ride on poor roads. The rear axle dispensed with a differential, instead disengaging one wheel in corners to limit tire scrub. By late 1907 the Model B replaced the original friction drive with a two-speed planetary transmission. By October 1909 the Model D had grown to an 80-inch wheelbase with a 10 hp engine. Brush Runabouts gained publicity through endurance events: a Brush was the third car to summit Pikes Peak under its own power in 1908, and in 1912 Sid Ferguson and Francis Birtles completed the first east-to-west motor crossing of Australia in one.

At peak output in 1910–1911 the company was selling thousands of runabouts a year; total production across the marque's life is estimated at approximately 10,000–13,250 vehicles. The company was renamed the Brush Runabout Company in 1909 and absorbed into Benjamin Briscoe's United States Motor Company combine around 1910, alongside Maxwell-Briscoe and Stoddard-Dayton. When USMC collapsed in 1913, Brush production ended. The open runabout body style had by then fallen out of favor as buyers gravitated toward enclosed cars and the ever-cheaper Model T Ford.
