Sales Brochure for the 1903 Oldsmobile, Olds Motor Works, "The Oldsmobile Ahead"

Olds Motor Works introduced its Curved Dash automobile in 1901. The one-cylinder runabout wasn't particularly powerful or robust, but at $650 it was relatively cheap. The car was a hit and Oldsmobile was building 5,000 units a year by 1904, making the Curved Dash the first mass-produced car in the United States -- if not the world.
