6 wheels racing car

This is the 24 hour Le-Mans racing car of 2030 for Michelin Challenge Design. One of the latest works.
Description: I don't think something will change drastically in car racing, with the exception of energy source. I strongly believe, that most cars in the world would be electric.
This particular car has 6 wheels and 8 electric motors (2 motors per each rear wheel). Each rear wheel has an individual 2 shift gearbox. Each motor has 250 KW of power, so, total power of electric motors is 2000 KW (2720 hp) on peak. Such power can be reached with the help of supercapacitors, that can be recharged by main battery or by regenerative braking.
I don't think, that Le-Mans cars would be limited by power. I consider, that the preferable way is to limit cars of each class by energy consumption. For example, 6 MW*h of energy on race for LMP1 class, 4 MW*h for class LMP2 and GT1, and 3 MW*h for GT2. 2.5 MW*h for GT3. It is the total energy, allowed for charging of a single car. This will make rac
