Karl Benz patented the three-wheeled Patent Motorwagen on 29 January 1886 and produced it as the first commercially available automobile from 1886 through 1893. He followed this initial success with the introduction of the Benz Velo model of 1894. The Velo and the Duryea Motor Wagon, patented in 1895, are credited as the first standardized cars. 67 Benz Velos were built in 1894 and 134 in 1895. The early Velo had a 1L 1.5 hp engine and later a 3 hp engine giving a top speed of 12 mph (19 km/h).
