In 2017, Mecachrome partnered with Ginetta as an engine supplier for the G60-LT-P1 LMP1 Prototype, supplying the 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 CEFC TRSM, was to compete in the 2018 24 Hours of Le Mans and the full 2018–19 FIA World Endurance Championship. 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 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. 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. 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.
