The new rule is under evaluation as part of a planned expansion of the WEC grid to a minimum of 40 cars from the current 37-strong field for 2025, Autosport has learned.
It would remove the ability of a factory team to run a single car as Cadillac Racing has done since last season, Iron Lynx Lamborghini is doing this year and as the Heart of Racing Aston Martin squad has announced for next season.
The rule preventing Hypercar manufacturers from running more than two factory cars would remain in place.
Only at the Blue Riband Le Mans 24 Hours WEC round are more than two cars permissible, although additional entries do not score either manufacturers' or drivers' points.
The move would at least partially bring Hypercar in line with the new-for-2024 LMGT3 category, which mandates that each manufacturer is represented by a single two-car team.
WEC promoter and co-organiser, the Automobile Club de l’Ouest, has declined to comment on the prospect of a two-car rule, which looks almost certain to be implemented for the new season.
News of the plan follows the admission from Chip Ganassi Racing earlier this month that its deal to run one-car factory programmes with the Cadillac V-Series.R LMDh in both WEC and the IMSA SportsCar Championship will come to an end at the conclusion of 2024.
