The Cadillac V16 engine was a type of automobile engine produced in the 1930s. Cadillac produced two of only three production, gasoline-fueled V16 engine models in history. Both were used in the Cadillac V-16 automobile, the first from 1930 until 1937, and the second between 1938 and 1940. The company has twice attempted to build a new V16 engine, once in the 1980s and again in 2003, but these have yet to be put into production. The only other 16-cylinder automotive engines ever attempted were Bugatti's 1915 U16, Marmon's V16, and Cizeta-Moroder's V16. A modern, quad- turbocharged W16 engine was used in the EB 16/4 Veyron built by the new Audi-owned Bugatti in the 2000s.
