Clément-Bayard entered 3 cars for the inaugural 1906 French Grand Prix at Le Mans where Albert Clément finished third in his 100Hp machine. He completed the 1,238 km event in 12 hours 49 minutes 46.2seconds. Clément lead the race at the end of laps 2 and 5 on the second day. Punctures were common and Michelin introduced a detachable rim, saving 11 minutes over manually replacing the tyre. This enabled Felice Nazzaro (FIAT) to take second place from Clément.
