The Model D was a four-seat passenger car produced by General Motors under the Oldsmobile brand in 1909, replacing the Model M. It was the last car engineered by Oldsmobile before it became a division of GM and began sharing a platform with Buick.[1]
History
The Model D was equipped with a side-valve, in-line 336 cu in (5,506 cc) 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.[2]
The brake pedal came into contact with the drum brake on the rear wheels. The Model D had a wheelbase of 112 in (2,845 mm) and was offered as a 5 passenger touring car, 4-door landaulet or 4-door sedan, with a retail price of US$4,000 ($135,644 in 2023 dollars [3]) for the Landaulet, while the Cadillac Model D was sold for US$2,800.[2] The previously offered 2-door roadster was now given its own designation called the Model DR.[2]
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.[2]
