Cadillac Type 51
The Cadillac Type 51 was a large, luxurious automobile introduced in September 1914 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.
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.
