Dufaux was a Swiss car manufacturer established in Geneva in 1904 by Charles and Frédéric Dufaux. The first Dufaux was built to enter the famous Gordon Bennett Cup race, held that year in the region of Taunus near Frankfurt am Main. The car had an eight-in-line engine with a displacement of no less than 12,760 cc, delivering 80 bhp (60 kW) at 1300 rpm. The event was a total failure for the Dufaux brothers as their car with the number 7 not even could start because of a broken wheel. This car still exists and is permanently exhibited at the Musée Nationale de l'automobile (Collection Schlumpf / Cité de l'Automobile) in Mulhouse (France). As Frenchman Léon Théry on Richard-Brasier won the race, France had to organize the cup for 1905.
