The first carriage-sized automobile suitable for use on existing wagon roads in the United States was a steam-powered vehicle invented in 1871, by Dr. J.W. Carhart, a minister of the Methodist Episcopal Church, in Racine, Wisconsin.
Other scholars say that the first American car is generally considered to be the Duryea automobile built by the Duryea Motor Wagon Company which was first demonstrated in Massachusetts in 1893 (pictured above).
