The gasoline-powered Curved Dash Oldsmobile is credited as being the first mass-produced automobile, meaning that it was built on an assembly line using interchangeable parts. It was introduced by the Oldsmobile company in 1901 and produced through 1907. 425 were produced the first year,[3] 2,500 in 1902, with over 19,000 built in all.[4] When General Motors assumed operations from Ransom E. Olds on November 12, 1908,[5] GM introduced the Oldsmobile Model 20, which was the 1908 Buick Model 10 with a stretched wheelbase and minor exterior changes.[6]

It was a runabout model, could seat two passengers, and sold for US$650. While competitive, due to high volume, and priced below the US$850 2-seat Ford Model C "Doctor's Car",[7] it was more expensive than the Western 1905 Gale Model A roadster at US$500. The Black sold for $375,[8] and the Success for US$250.[9]

The flat-mounted water-cooled single-cylinder engine, situated at the center of the car, produced 5 hp (3.7 kW),[2] relying on a brass gravity feed carburetor. The transmission was a semi-automatic design with two forward speeds and one reverse. The low-speed forward and reverse gear system are a planetary type (epicyclic). The car weighed 850 lb (390 kg) and used Concord springs.[citation needed] It had a top speed of 20 mph (32 km/h).[10]

The car’s success was partially by accident — in 1901 a fire destroyed a number of other models before they were approved for production, leaving the Curved Dash the only one intact.[11]
