Clément-Bayard entered 3 cars for the 1906 French Grand Prix at Le Mans where 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 tyre manufacturer Michelin introduced a detachable rim with a tyre already affixed, which could be swapped in about 4 minutes car after a puncture, saving 11 minutes over manually replacing the tyre. These wheels were used by Felice Nazzaro on his FIAT enabling him to wrest second place from Clément on the second day. His father Adolphe was the owner of Dunlop France.
