In 1887, Ransom Olds developed an experimental steam-powered car. An updated version of the car was featured in the May 21, 1892 issue of Scientific American. A company in London saw the article and bought the car, making it the first American-car sold for export! The two-passenger vehicle was good for 15-miles per hour. Olds would go on to form the Olds Motor Works and sell 4000 Oldsmobiles by 1903.
