In 2017, Mecachrome partnered with [[Ginetta]] as an engine supplier for the [[Ginetta G60-LT-P1|G60-LT-P1]] LMP1 Prototype, supplying the [[Mecachrome V634 engine|V634P1, a variant of the V634 F2 engine]], which would also be turbocharged by Van Der Lee Turbo Systems. The Ginetta G60-LT-P1-AER, run by [[Manor Motorsport|CEFC TRSM]], was to compete in the [[2018 24 Hours of Le Mans]] and the full [[2018–19 FIA World Endurance Championship]].<ref>{{cite web|url=http://sportscar365.com/lemans/wec/mecachrome-confirmed-as-ginetta-lmp1-engine-supplier/|title=Mecachrome Confirmed as Ginetta LMP1 Engine Supplier - Sportscar365|work=sportscar365.com|date=28 February 2017 |access-date=1 March 2017}}</ref> However, after withdrawing from the opening WEC round at [[Spa-Francorchamps]] and achieving a fifth in class result at Le Mans, which was in reality a 41st position result in the overall standings, Ginetta dropped the Mecachrome V634P1 in favour of the [[Advanced Engine Research|AER P60B]] engines. This was done due to a performance deficit from the turbo V6 engine, and the lack of response to calls for a development programme from Mecachrome Motorsport, with the stated aim being to unlock the true performance of the chassis.<ref>{{Cite web|url=http://www.dailysportscar.com/2018/08/03/ginetta-to-test-with-aer-engine-as-trsm-set-to-withdraw-from-silverstone.html|title=Ginetta To Test With AER Engine As TRSM Set To Withdraw From Silverstone – dailysportscar.com|website=www.dailysportscar.com|access-date=2019-12-12}}</ref> Mecachrome Motorsport responded to Ginetta's announcement soon afterwards, also revealing that it intended to continue its LMP1 engine programme, although it has yet to find any customers to run the engine in any chassis since.<ref>{{cite web |title=Mecachrome Motorsport Responds to Ginetta LMP1 Announcement |url=http://mecachromemotorsport.com/2018/08/06/mecachrome-motorsport-responds-to-ginetta-lmp1-announcement/ |website=Mecachrome Motorsport |access-date=6 August 2018 |archive-date=9 August 2018 |archive-url=https://web.archive.org/web/20180809203649/http://mecachromemotorsport.com/2018/08/06/mecachrome-motorsport-responds-to-ginetta-lmp1-announcement/ |url-status=usurped }}</ref> Ginetta technical director Ewan Baldry later responded to Mecachrome's claims, acknowledging that while the engine utilised at Le Mans was a first specification engine, the engine was underpowered and did not meet the contractually agreed performance targets.<ref>{{cite web|title=Mecachrome Respond To Silverstone TRSM Withdrawal (Plus Ginetta Response)|url=http://www.dailysportscar.com/2018/08/06/mecachrome-respond-to-silverstone-trsm-withdrawal-plus-ginetta-response.html|access-date=12 December 2019}}</ref>

From the [[2024 FIA World Endurance Championship|2024 WEC season]] onward, Mecachrome provided the engines for the two [[Signatech|Alpine-entered]] [[Alpine A424|A424s]], supplying a heavily modified version of the [[Mecachrome V634 engine|V634]] engine used in FIA Formula 2.<ref name="msw2">{{cite web |last=Oakley |first=Phil |date=16 June 2023 |title=New Alpine A424 Hypercar will use 'heavily modified' version of F2 engine |url=https://www.motorsportweek.com/2023/06/16/new-alpine-a424-hypercar-will-use-heavily-modified-version-of-f2-engine/ |url-status=live |archive-url=https://web.archive.org/web/20230713093402/https://www.motorsportweek.com/2023/06/16/new-alpine-a424-hypercar-will-use-heavily-modified-version-of-f2-engine/ |archive-date=13 July 2023 |access-date=13 July 2023 |work=Motorsportweek}}</ref> At the [[2024 24 Hours of Le Mans]], both Alpines retired with engine issues: the #35 entry stopped at Arnage after five hours with smoke blowing out of the car, whilst the #36 ended their race in the pits during hour 6.<ref>{{Cite web |date=2024-06-15 |title=LM24, Hour: 6: Alpine drops out of the fight |url=https://racer.com/2024/06/15/lm24-hour-6-alpine-drops-out-of-the-fight/ |access-date=2024-07-03 |website=RACER |language=en-US}}</ref><ref>{{Cite web |title=2024 LM24 Hour 5: #35 Alpine Suffers Mechanical Failure |url=https://www.dailysportscar.com/2024/06/15/2024-lm24-hour-5-35-alpine-suffers-mechanical-failure-83-ferrari-holds-advantage.html |access-date=2024-07-03 |website=www.dailysportscar.com}}</ref>
