The FIA has signed off new rules which will permit hypercar-based vehicles to compete in the top-tier of the World Endurance Championship, including at the Le Mans 24 Hours.

On Thursday, the FIA World Motor Sport Council revealed in the Phillippines that future prototype racers will be created on budgets one-quarter of current LMP1 vehicles and that there will be “freedom of design based on a hypercar concept.”

Motorsport reports that additional details will be announced by the Automobile Club de l’Ouest next Friday prior to the Le Mans 24 Hours.

The FIA hopes that the new regulations will allow manufacturers to retain their current level of performance but for significantly less money. It is reported that manufacturers won’t be able to use the same level of hybrid technology as they can in LMP1 and that they will be offered an energy-retrieval system instead of developing their own.

Car manufacturers involved in the formation of the new rules included Toyota, Ford, Ferrari, and perhaps most excitingly, both McLaren and Aston Martin.

The two British car manufacturers have both previously expressed their openness to race the Valkyrie and Senna hypercars at the world’s most famous endurance race if regulation changes like those announced were made.
