The Chalmers Motor Company was an American automobile manufacturer headquartered in Detroit, Michigan. Founded in 1908 by Hugh Chalmers, the company was known for producing high-end vehicles. Chalmers automobiles gained recognition for their toughness, durability, and engineering receiving particular praise for their performance in touring events. The company reached its peak in 1911, becoming the eighth-largest auto producer in the United States. Despite initial success, the company faced challenges with increasing competition in the auto industry, and sales began to decline in the following years. In 1923, Chalmers Motor Company merged with Maxwell Motor, ultimately forming the basis for the Chrysler Corporation.

Maxwell was an American automobile manufacturer which ran from 1904 to 1925. The present-day successor to the Maxwell company was Chrysler, now Stellantis North America, which acquired the company in 1925.
