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 examples were produced the first year, 2,500 in 1902, with over 19,000 built in all. 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.
