De Dion Bouton et Trepardoux Dos-a-Dos Steam Runabout - the Worlds Oldest Running Road Legal Car
It is the world’s oldest racing car, the world’s oldest running motor car in private hands, and the holder of many prestigious awards.


The French visionary entrepreneur Conte De Dion teamed with two talented mechanics, Georges Bouton and Charles-Armand Trepadoux. Before the advent of the Otto cycle engine, steam was the only game in town, and Trepadoux was one of its more creative minds. By inventing a compact and fast boiler – one that could produce usable steam pressure in minutes – the way was opened to practical in a small, over-the-road package.

It stems from the advent of steam that ushered in the Industrial Revolution, and it is a clear descendant of the British road-going locomotives that were mercilessly stamped out by the railroads.




The 1884 De Dion steamer was nicknamed ‘La Marquise’ after the Conte de Dion’s mother. Measuring just nine feet in length, ‘La Marquise’ features twin compound steam engines, ‘spade handle’ steering and seats four people ‘dos-a-dos’ (back-to-back). The seats are located on top of the steel tank, which holds 40 gallons of water. The engine was mounted in the front, driving the front wheels and steering in the rear wheels.
