The car used a complicated 3-speed planetary transmission and had a governed throttle, essentially a primitive cruise control. The engine was designed by Alanson P. Brush, who left Cadillac shortly afterwards. ==Model H & L== The Model D was replaced for 1906 with the Model H and larger Model L.

Both came in two or more body styles. The Model H continued in production through 1908, while the Model L was cancelled, and a Limousine was added as a body style. 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 Model D」の詳細全文を読む スポンサード リンク
