The car currently is carefully balanced between its two motors. There is a computer system that moderates between the two systems when the car is not in electric only or ICE only mode. Setting aside the fact that the mods to pump out more horsepower would almost certainly void the warranty in what is a very expensive car to repair, I suspect modifications would completely change the way the car drives, and not necessarily for the better.

It all goes back to that computer system and the way it has balanced between the two motors. Unless that can be changed in order to maintain the balance that currently exists, I believe only bad will come out of modding. So you're going to need a computer programmer who knows how the car is programmed and also knows how to maintain the balance when the horsepowers are increased.

Having said that, if you want to be the guinea pig I will be fascinated in the outcome. And I hope I am wrong on all counts -- as to the warranty and as to the balance of the car.
