Renault began [[Formula One French engine manufacturers|manufacturing engines]] at the Viry-Châtillon factory in 1976, after closing the former [[Alpine (car maker)|Alpine]] competition department,<ref name="RS2">{{cite web|url=http://www.grandprix.com/ns/ns19525.html |title=Jean Redele |work=Grandprix.com|publisher=Inside F1|date=15 August 2007 |access-date=17 October 2011}}</ref><ref name="RS3">{{cite web|url=http://www.pitpass.com/30067/Viry-Chtillon-30-years-of-innovation-and-expertise |title=Viry-Châtillon: 30 years of innovation and expertise |work=Pitpass.com |date=12 December 2006 |access-date=17 October 2011}}</ref> which was run in conjunction with the Formula One team under the [[Renault Sport]] division.<ref name=RS2 /><ref name=RS3 /> It manufactured the first [[turbocharged]] engine seen on the category,<ref name="RS4">{{cite web |url=http://www.renault.com/en/PassionSport/sport-automobile/Documents_Without_Moderation/saga-f1-en.pdf |title=Renault and F1 |publisher=Renault |access-date=17 October 2011 |archive-url=https://web.archive.org/web/20120106012633/http://www.renault.com/en/PassionSport/sport-automobile/Documents_Without_Moderation/saga-f1-en.pdf |archive-date=6 January 2012 |url-status=dead }}</ref> the [[Renault EF-Type engine|Renault-Gordini EF1]] 1.5 litres [[V6 engine|V6]],<ref name=RS4 /><ref>{{cite web|url=http://www.renault.com/en/passionsport/les-vehicules-historiques/pages/formule-1-rs-01.aspx|archive-url=https://web.archive.org/web/20130529142847/http://www.renault.com/en/PassionSport/les-vehicules-historiques/Pages/formule-1-rs-01.aspx|archive-date=29 May 2013 |title= RS01 |publisher=Renault |access-date=17 October 2011}}</ref> at a time where the naturally aspirated 3-litre engines were predominant.<ref name=RS4 /> Initially only supplying engines to the works team, Renault began a customer programme in 1983 when it became [[Team Lotus]]' engine supplier.<ref name="RS1">{{cite web|url=http://www.grandprix.com/gpe/con-renau.html|title=Constructors: Renault F1|work=Grandprix.com|publisher=Inside F1|access-date=17 October 2011}}</ref> [[Mecachrome]], a precision engineering company, prepared the engines for the customer teams.<ref name="Mec">{{cite web|title=Mecachrome|url=http://www.grandprix.com/gpe/eng-mecac.html|work=Grandprix.com|publisher=Inside F1|access-date=3 February 2012}}</ref>

Though not competitive initially, with the recruitment of designer [[Gérard Ducarouge]] the marque gained competitiveness towards the later part of the 1983 season into 1984, with [[Nigel Mansell]] and [[Elio de Angelis]] scoring regular podiums. That year, Renault also began supplying engines to the [[Équipe Ligier|Ligier]] team,<ref name="LP">{{cite web|title=Ligier Profile|url=http://www.grandprix.com/gpe/con-ligie.html|work=Grandprix.com|publisher=Inside F1|access-date=3 February 2012}}</ref> which scored three points in 1984, an improvement over not being classified in the 1983 championship. [[Ayrton Senna]] joined [[Team Lotus]] in 1985 and the combination of his talent and the fast, but fuel-inefficient [[Lotus 97T]] gained eight pole positions and three wins (two to Senna, one to de Angelis), but unreliability prevented a sustained attempt at either title. The Tyrrell team started using the Renault engine from the seventh Grand Prix of the year, while Ligier gained three podiums in the [[Ligier JS25]]. In 1986, [[Aristocracy (class)|aristocrat]] [[John Crichton-Stuart, 7th Marquess of Bute|Johnny Dumfries]] was chosen to be Senna's new partner at Lotus after Senna vetoed the original choice of [[Derek Warwick]]. More pole positions and two wins for the Brazilian followed with the [[Lotus 98T]], but the car followed similar problems as its predecessor with reliability problems and poor fuel consumption. This saw to it that Lotus could not sustain a season-long challenge to leading teams [[McLaren]] and [[Williams Racing|Williams]].

After the 1985 season, the Renault works team ended participation in Formula One but continued as an engine supplier for [[Équipe Ligier|Ligier]], [[Tyrrell Racing|Tyrrell]] and Lotus. 1986 saw the introduction of the EF15B engine, which included several innovations, like static ignition and pneumatic valve return. Renault Sport stopped its engine program at the end of the year, having scored 19 pole positions and 5 Grand Prix victories with customer teams.<ref name=RS4 />

==== Success with Williams and Benetton (1989–1997) ====
[[File:Williams FW14B (35029084126) (cropped).jpg|thumb|Renault secured its first titles in {{F1|1992}} with the [[Williams Racing|Williams]]-Renault FW14B.]]

Renault returned as a Formula One engine supplier in 1989 with the banning of turbocharged engines, in partnership with the [[Williams Racing|Williams]] team. The Viry factory produced the first [[Pneumatic valve springs|pneumatic valved]] 3.5 [[V10 engine]], the RS1, while other engine manufacturers supplied [[V8 engine|V8]] ([[Ford Motor Company|Ford]], [[Judd (engine)#Formula One|Judd]] and [[Yamaha Motor Company#Formula One|Yamaha]]), V10 ([[Honda in Formula One|Honda]]), or [[V12 engine|V12]] ([[Ferrari V12 F1 engine|Ferrari]] and [[Lamborghini V12#Formula One|Lamborghini]]) engines.<ref name=RS4 /> The Williams-Renault combination scored its first victory at the wet [[1989 Canadian Grand Prix]], with [[Thierry Boutsen]], and finished their initial season together with Boutsen winning the very wet [[1989 Australian Grand Prix]].<ref>{{cite web |url=http://www.f1network.net/main/s107/st4064.php |title= Williams Team History 1989–1996 |publisher=F1network.net |access-date=1 December 2011}}</ref>

Williams had signs of promise for the next two years and by {{F1|1992}}, with the aid of [[active suspension]] and better engines, the Williams-Renault was a World Championship-winning car, winning over half of the races during the season, as its driver [[Nigel Mansell]] won the drivers' title.<ref name=RS4 /> Former customer team Ligier also resumed using the same works Renault engines as Williams in 1992.<ref name=RS4 /> The championship was won again by Williams in {{F1|1993}}, using the technologically advanced [[Williams FW15C]] car – the team had developed technology such as [[anti-lock brakes]], [[traction control]] and [[power steering]], along with using the RS5 engine with a redesigned intake and combustion.<ref name=RS4 /> [[Alain Prost]] won the Drivers' Championship after winning 7 of the 16 rounds, and his teammate [[Damon Hill]] won another three Grands Prix.

[[File:Michael Schumacher - Benetton B195 at the 1995 British Grand Prix, Silverstone (49704066181).jpg|left|thumb|[[Michael Schumacher]] driving a [[Benetton Formula|Benetton]]-Renault B195 at the [[1995 British Grand Prix]]]]

{{F1|1994}} saw Williams driver [[Ayrton Senna]] killed at the [[1994 San Marino Grand Prix]], which left the Brazilian's inexperienced teammate [[Damon Hill]] as team leader. Hill was 37 points behind Championship leader [[Michael Schumacher]] by the [[1994 French Grand Prix|French Grand Prix]], but had managed to close the gap down to 1 point before the last race in [[1994 Australian Grand Prix|Adelaide]]. The two drivers collided controversially and retired from the race, making Schumacher the Drivers' Champion while Williams retained the Constructors' Championship.

[[File:Jacques Villeneuve 1996.jpg|thumb|right|[[Jacques Villeneuve]]'s Williams-Renault in {{F1|1996}}. He would win the {{F1|1997}} title using a Renault-powered car.]]

In 1995 engine regulations reduced maximum engine displacement to three litres, with Renault adapting the RS7, making it lighter and featuring a fly-by-wire throttle. [[Benetton Formula|Benetton]] acquired Ligier's Renault engines for {{F1|1995}} and their driver, Michael Schumacher, managed to successfully defend his drivers' title by 33 points from his nearest rival, Damon Hill. Benetton won the constructors' title by 29 points, winning 11 races during the season. Williams won the next two seasons in both the drivers' and Constructors' Championship with Damon Hill winning the title in {{F1|1996}} and [[Jacques Villeneuve]] in {{F1|1997}}. Schumacher and other Benetton staff left for Ferrari in 1996, and the team finished in the third position for both years.

==== Initial end of factory Renault engines, Mecachrome and Supertec (1998–2000) ====
{{See also|Mecachrome|Supertec}}
Renault left the F1 again at the end of 1997, and evolutions of its last engine, the RS9, were still used by many teams during the following seasons.<ref name=RS4 /> Renault continued working with [[Mecachrome]], which paid for development of the engines,<ref name=Mec /> and supplied them to Williams under the Mecachrome name.<ref name="RS5">{{cite web|url= http://www.statsf1.com/en/moteur-mecachrome.aspx |title= Engine Mecachrome |publisher=STATSF1.com |access-date=17 October 2011}}</ref> Benetton continued to use the engines under the [[Playlife]] brand until 2000, although only achieved several podiums during this time. [[Flavio Briatore]]'s company [[Supertec]] distributed the engines from 1999,<ref name="St">{{cite web|title=Supertec|url=http://www.grandprix.com/gpe/eng-super.html|work=Grandprix.com|publisher=Inside F1|access-date=4 February 2012}}</ref> with Williams and [[British American Racing|BAR]] using them under the Supertec name that year, and the [[Arrows F1|Arrows]] cars using them in 2000, while Benetton used them under the Playlife name in 1999 and 2000.<ref name=RS6 /> Although on a few occasions points were scored, ultimately the engines were not successful under Supertec's control, subsequently all but one team moved to another supplier after one season.<ref name=St /><ref name="RS6">{{cite web|url=http://www.statsf1.com/en/moteur-supertec.aspx |title= Engine Supertec |publisher=STATSF1.com |access-date=17 October 2011}}</ref>

==== Return to customer supply with Red Bull Racing yields title success (2007–2010) ====
After Renault purchased the Benetton team, they did not supply customer engines until {{F1|2007}}, when they signed an agreement with [[Red Bull Racing]] on 15 September 2006. Red Bull were a midfield team during the first two years of the partnership, before a change in regulations for the {{F1|2009}} season allowed Red Bull to claim their first victory at the {{F1 GP|2009|Chinese}}.<ref>{{cite web| url=http://www.f1fanatic.co.uk/2009/04/19/vettel-leads-webber-in-red-bull-one-two-chinese-grand-prix/ |title=Vettel leads Webber in Red Bull one-two (Chinese Grand Prix review) |publisher=F1fanatic.co.uk|date=19 April 2009 |access-date=1 December 2011}}</ref> Drivers [[Sebastian Vettel]] and [[Mark Webber (racing driver)|Mark Webber]] took five further victories that year to allow the team to finish second in the Constructors' Championship. In 2010, Vettel and Red Bull won both championships, making it the ninth title for a Renault engine, and the first for the RS27.<ref>{{cite web |url=http://www.media.renault.com/download/media/specialfile/12375_1_5.aspx |title=Renault Engines Secure Ninth F1 Constructors' Title |publisher=Renault |date=8 November 2010 |access-date=1 December 2011 |url-status=dead |archive-url=https://web.archive.org/web/20120406065838/http://www.media.renault.com/download/media/specialfile/12375_1_5.aspx |archive-date=6 April 2012 }}</ref>

In September 2017, Renault and McLaren announced the latter would use customer Renault engines from 2018 to 2020 in order to aid the competitiveness of the Renault works team. Toro Rosso in turn switched to full-works Honda engines, terminating their 2018 customer deal with Renault.<ref>{{Cite web|url=https://www.formula1.com/en/latest/headlines/2017/9/renault-power-for-2018-mclaren--honda-switch-to-toro-rosso.html|title=Renault power for 2018 McLaren, Honda switch to Toro Rosso|date=15 September 2017|website=formula1.com |publisher=Formula One World Championship Limited |access-date=10 November 2017}}</ref> In June 2018, Red Bull announced they would also use full-works Honda engines from 2019 onwards.<ref>{{cite web|url=https://www.formula1.com/en/latest/headlines/2018/6/red-bull-and-honda-agree-two-year-engine-deal-.html|title=Red Bull and Honda agree two-year engine deal|website=formula1.com|access-date=19 June 2018}}</ref> As [[McLaren]] ended its Renault customer partnership due to switching to [[Mercedes AMG High Performance Powertrains|Mercedes]] power units from 2021 season, Renault returned to single-team engine supply for the first time since the [[2006 Formula One World Championship|2006 season]]. This remained the case until Renault ceased its engine development and supply at the end of the 2025 season. 

The Enstone-based team was rebranded to [[Alpine F1 Team|Alpine]] from the 2021 season onwards while Renault was retained as the engine make, marking the first time since 2015 that the Renault brand would be in Formula One solely as an engine supplier.<ref>{{Cite web|url=https://www.f1head.nl/teams/renault/|title=Renault Formule 1 team|date=16 September 2023|website=f1head.nl |publisher=F1Head |access-date=16 September 2023}}</ref>

However, despite the rebranding of the Enstone team and a win for Alpine driver [[Esteban Ocon]] at the [[2021 Hungarian Grand Prix]],<ref>{{Cite web |date=2021-08-01 |title=Ocon fights off Vettel to take shock Hungarian GP win |url=https://www.the-race.com/formula-1/ocon-fights-off-vettel-to-take-shock-hungarian-gp-win/ |access-date=2025-02-24 |website=The Race |language=en}}</ref> the Renault power unit still continued to struggle overall relative to the competition from Honda, Ferrari and Mercedes. During 2023, Alpine – whose [[Alpine A523|A523]] car was on average 0.9 seconds slower than the pacesetting Honda-powered [[Red Bull Racing RB19|Red Bull RB19]] – claimed their car had been cost half a second of performance versus its competitors purely because of the lacklustre Renault power unit. With a power unit more on par with its rivals, Alpine claimed the A523 would have been in performance terms about on par with the [[Mercedes W14]].<ref>{{Cite web |date=2024-01-02 |title=F1's worst works team is stuck with its laptime-killing problem |url=https://www.the-race.com/formula-1/alpine-f1-team-engine-deficit-worst-works-team/ |access-date=2025-02-24 |website=The Race |language=en}}</ref>

Due to the lack of success and unreliability of their engines since the beginning of the V6 turbo-hybrid era in [[2014 Formula One World Championship|2014]], on 29 September 2024, Renault announced that it would be ending its works engine programme and would therefore cease to provide engines for Alpine after 2025, when revised engine regulations are set to be introduced in [[2026 Formula One World Championship|2026]].<ref>{{Cite web |title=Alpine to close works engine programme at the end of 2025 |url=https://www.formula1.com/en/latest/article/alpine-confirm-they-are-to-shut-down-works-engine-programme-at-the-end-of.2Bcubn03U8oaIOMFVggZDl |access-date=2024-09-30 |website=Formula 1® - The Official F1® Website |language=en}}</ref> [[Groupe Renault]] CEO [[Luca de Meo]] has stated financial reasons as the main reason behind ending the programme, claiming that it would be cheaper to purchase a power unit from another manufacturer than continue to develop one in-house.<ref>{{Cite web |last=Noble |first=Jonathan |title=What we learned about Renault's F1 engine shutdown |url=https://www.motorsport.com/f1/news/what-we-learned-about-renaults-f1-engine-shutdown/10661130/ |website=Motorsport.com}}</ref> Said manufacturer would be revealed by Alpine to be [[Mercedes-Benz in Formula One|Mercedes]], becoming a customer team by utilising their [[Mercedes AMG High Performance Powertrains|engines]] and gearboxes from the 2026 season onward.<ref>{{Cite web |date=2024-11-12 |title=Alpine to use Mercedes power units and gearboxes from 2026 |url=https://www.formula1.com/en/latest/article/alpine-to-use-mercedes-power-units-and-gearbox-from-2026.5jzzbQeHx7aPT3hoP5hRtc |language=en-US}}</ref>

Following the [[2025 Japanese Grand Prix]] held at the [[Suzuka Circuit]] an article by journalist Scott Mitchell-Malm for motorsport website ''The Race'' revealed that during qualifying for that event Alpine and their Renault power units were particularly slow in the second sector of the lap on that track which contains two long straight with the Alpine's losing 0.6 seconds in that sector further emphasising Renault's horsepower issues in the hybrid era with Mitchell-Malm saying such data vindicated Renault's decision to end its engine supply and development at end of 2025.<ref>{{Cite web |date=2025-04-09 |title=A controversial F1 decision is proving a no-brainer |url=https://www.the-race.com/formula-1/whats-proving-alpines-most-controversial-f1-decision-right/ |access-date=2025-04-24 |website=The Race |language=en}}</ref>
