thumb The first Cadillac automobiles were the 1903 Model built in the last quarter, 1902. These were 2-seater "horseless carriages" powered by a reliable and sturdy single-cylinder engine developed by Henry Martyn Leland and built by Leland and Faulconer Manufacturing Company of Detroit, of which Henry Leland was founder, vice-president and general manager. Reformed as the Cadillac Automobile Company in August 1902, it began manufacturing the runabouts and named them "Cadillac" after the city's founder Antoine Laumet, the self-styled Antoine Laumet de La Mothe, sieur de Cadillac. The 1904 Model B was a refinement of the 1903 and while still a mid-engined, one cylinder automobile, it now had an extended front and transverse front suspension. With the introduction of the Model B, the 1903 style became known as the Model A . Both the Model A and B were available as a two passenger runabout or four passenger rear tonneau. Catalogs also show a light delivery. The one cylinder Cadillac continued to be offered through 1908 in the runabout, tonneau or delivery bodies under a variety of Model designations which are delineated below. ==Single-cylinder engine== The Models A, B, C, E, and F shared a single-cylinder engine rated from 6.5 to around depending on model. The cylinder was horizontal, pointing rearward, and was cast from iron with a copper water jacket. Bore and stroke were square at . The engine was named by its manufacturers, Leland and Faulkner, "Little Hercules". The engine employed a patented variable-lift intake valve licensed from Alanson P. Brush. The restrictions of this design using Brush's patents led the company to develop their own four-cylinder engine for the later Models D, L, G, and H. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Cadillac Runabout and Tonneau」の詳細全文を読む スポンサード リンク
