Cadillac Type 51
The Cadillac Type 51 is a large, luxurious automobile that was introduced in September 1914 by Cadillac as a 1915 model. It was Cadillac's first V8 automobile, replacing the four-cylinder Model 30. The similar Types 53, 55, 57, 59, and 61 lasted through 1923, when the design was substantially updated as the Type V-63. It used the GM A platform for the entire series. It was built at the Cass Street and Amsterdam Avenue factory in Detroit, with the body provided by a number of coachbuilders, including Fleetwood Metal Body in Fleetwood, Pennsylvania.
All of these models used a new L-head V8 engine, one of the first V8 engines ever mass-produced and a substantial differentiator for the marque. All bodies were built by Fisher. The Type 51 was also the first left-hand drive Cadillac—all previous models had been right-hand drive, which was continued as an option. Wheelbases varied in those years, with 122 in (3099 mm) at the low end and 145 in (3683 mm) as the longest.
In July 1917, the United States Army needed a dependable staff car and chose the Cadillac Type 55 Touring Model after exhaustive tests on the Mexican border. 2,350 of the cars were supplied for use in France by officers of the American Expeditionary Force in World War I.
