Sizaire-Naudin was a small French manufacturer founded in 1905. The cars were design by Maurice Sizaire and built by his partner, Louis Naudin. With racecars, much like the one featured here, Sizaire-Naudin won the Coupe de l’Auto races in 1906, 1907 and 1908.

This particular model features one of the most powerfull single cylinder engines for its period. Thanks to the power, and unusual independant front suspension, the 12HP won many class victories.
