Clément obtained consent from the Conseil d'Etat to change his name to that of his business in 1909. The extra name celebrated the Chevalier Pierre Terrail, seigneur de Bayard who saved the town of Mézières in 1521. A statue of the Chevalier stood in front of Clément's Mézières factory, and the image was incorporated into the company logo.

From 1903 Clément-Bayard automobiles were built in a modern factory at Mézières, known as La Macérienne, which Clément had designed in 1894 mainly for building bicycles.
