Cadillac Model D

Model D 1905

The Cadillac Model D is an American brass age car that was introduced by Cadillac in January 1905, and sold throughout that year. It was a larger automobile than previous Cadillac offerings, and their first four-cylinder production model. Priced at $2800 ($94,951 in 2023 dollars [1]),[2] it can be seen as the first luxury car from the company.

The engine was a 300.7 in³ (4.9 L) four-cylinder L-head design producing a claimed 30 hp (22 kW). 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 Partridge Brush, who left Cadillac shortly afterwards.
