Renault's first badge was introduced in 1900 and consisted of the Renault brothers' intertwined initials. When the company started mass production in 1906, it adopted a gear-shaped logo with a car inside it. After World War I the company used a logo depicting an FT tank. In 1923 it introduced a new circle-shaped badge, which was replaced by the "diamond" or lozenge in 1925. The lozenge of Renault means a diamond that expresses the brand's firm desire to project a strong and consistent corporate image.
