History

Renault Energy F1 was unveiled on 21 June 2013 during 2013 Paris Air Show in order to replace the outgoing Renault RS27 naturally-aspirated V8 engine after seven years of service.^[3]

On 30 September 2024 it was announced that Renault would be pulling the plug on their F1 powertrains project at the end of the 2025 season, ahead of the 2026 regulation changes, with their historic Viry-Châtillon factory being repurposed as an engineering centre for Alpine and Renault cars.^[4]
