Antoine de la Mothe Cadillac
Upon his arrival in America, La Mothe adopted his title after the town of Cadillac, Gironde in southwestern France. The city of Detroit became the world center of automobile production in the 20th century. William H. Murphy and Henry M. Leland founded the Cadillac auto company and paid homage to him by using his name for their company and his armorial bearings as its logo in 1902. Various places bear his name in America, in particular Cadillac Mountain in Maine and the town of Cadillac, Michigan.

Cadillac powered the Cadillac Northstar LMP a Le Mans Prototype in the early years of the American Le Mans Series from 2000 to 2002. When the prototype proved unsuccessful, Cadillac withdrew from the series. Cadillac's most successful venture into motorsport in recent years has been its use of the CTS-V in the SCCA World Challenge Grand Touring class.
