Hi!
I wasn't aware until very recently the changes that have been introduced this year.
This is what I think is happening.
LMP1 have less energy - of course the ACO regularly tries to reduce speeds at LE Mans year on year.
Separately, they have allowed GTE cars to increase in performance, but for this year, that will only apply to GTE pro cars. These are higher performance than GT3 cars.
So the net effect, I believe is:
Slower P1
P2 no change, but faster next year
Faster GTE pro cars
GTE Am no change.
The track could get rather busy this year.
