Electrically speaking, its all about losses, more losses = heat build up = thermal cut out/damaged electrics.
And the more power you can deliver, the more heat you get.
And as for weight, that's all about choice. Many racing cars (1:1) can be made to drop in well below their classes lower weight limit. So they play with weight distribution/ballast (where its allowed) to improve handling.
So its not just this hobby, its anything that goes forwards under power.
They even spend millions making sure your 1.0L econobox commuter car has minimal losses/optimum heat rejection and good weight distribution. (well, in most cases.......)
