History
The Model D was equipped with a side-valve, in-line {{Convert|5506|cc|cuin|0|abbr=on|disp=flip}} four-cylinder engine developing 40 bhp. The engine was installed in the front, driving the rear wheels through a transmission shaft. The gearbox had three forward gears, with the gearshift lever positioned to the right of the driver.{{cite book |last1=Kimes |first1=Beverly |title=Standard catalog of American Cars 1805–1942 |date=1996 |publisher=Krause publications |isbn=0-87341-478-0 |pages=1061–1088 |edition=third}}
The brake pedal came into contact with the drum brake on the rear wheels. The Model D had a wheelbase of {{Convert|2845|mm|in|0|abbr=on|disp=flip}} and was offered as a 5 passenger touring car, 4-door landaulet or 4-door sedan, with a retail price of US$4,000 (${{formatnum:{{Inflation|US|4000|1908}}}} in {{Inflation-year|US}} dollars {{inflation-fn|US}}) for the Landaulet, while the Cadillac Model D was sold for US$2,800. The previously offered 2-door roadster was now given its own designation called the Model DR.
1,000 Model D were manufactured in 1908, and it was replaced by the Series 22 in 1910, and the roadster was called the Series 25.
