The Hammer was an automobile built in Detroit, Michigan by the Hammer Motor Company from 1905-06. The Hammer was a light car built with a two-cylinder, 12 hp engine in 1905. This was replaced with a 24 hp, four-cylinder engine for 1906. The five-seater tonneau weighted 1,800 lbs, and came with a choice of a planetary or sliding-gear transmission, with a shaft final drive. The Hammer Motor Company was formed as part of the Hammer-Sommer when they became defunct in 1905.
