The first Renault Sport was officially established as a company in 1976 as a merger between the Alpine and Gordini competition departments. It was made a division and reorganised in 2002 and 2016. In December 2021, all Renault Sport operations were merged into an Alpine-led business unit. The Renault Sport car range under Alpine was completely phased out by the end of 2023.
