The Type III was a motor vehicle with three wheels produced from 1887 to 1892 by De Dion-Bouton.
In the wake of the outcry from the presentation of the Dog Cart in 1883, the small French company De Dion, Bouton in Paris created a new vehicle, which unlike the previous model had three wheels, two in front and one behind.
This new model was introduced in late 1887 and was fitted with a steam engine placed anteriorly. This engine produced power up to 4.5 hp and accelerated the tricycle to a maximum speed of 20 km/h (12mph).
As in the case of the Dog Cart, this new model also underwent further refinement.
