As revealed by Autosport, F1 CEO Stefano Domenicali and FIA president Mohammed Ben Sulayem are eyeing a reduction in car weight for the next rules cycle in 2026.
F1's current generation of cars has a minimum weight of 798kg, which is the highest they have ever been in the history of the world championship.
With F1 braced for the potential for larger batteries in 2026 as a consequence of a greater contribution from electrical power, there are concerns that cars could get even heavier, which is why efforts will be made to bring things down.
But with the mass of the cars being so high now because of necessary safety devices and the hybrid components, there is some scepticism about how much of a step change can be done to bring the weight down.
Allison has suggested an alternative approach, however, is not trying to mandate specific areas of the car that can be made lighter.
Instead, he suggests that if the FIA simply reduces the minimum weight of the cars, then teams will naturally be forced to find ways to make the cars lighter.
Asked by Autosport about the best way to bring car weight down, Allison said: "I strongly agree with Stefano. He's not alone in thinking that this sort of inexorable upward trend in weight is something that has to be arrested and then reversed because year-on-year they have been getting heavier.
"It isn't super trivial to get the weight moving in the other direction, but it is particularly tricky to dream up technical rules that are going to make the car much lighter.
