Renault V6 hybrid Formula One power unit

The Renault E-Tech R.E. Series (previously known as Renault Energy F1, Renault R.E. and Renault E-Tech) is a 1.6-liter, hybrid turbocharged V6 racing engine developed and produced by Renault Sport F1 in partnership with Mecachrome for the FIA Formula One World Championship.

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.

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.

The Renault Energy F1-2014 was Renault's first-ever V6 hybrid turbocharged Formula One engine for the 2014 season. The Renault Energy F1-2014 engine was developed by Renault with technical support from Mecachrome for design research & development, trackside support, engine arrangement, preparation, tune-up and engine maintenance. The Renault Energy F1-2014 suffered reliability problems during pre-season testing.
