2400bhp in a truck… See this video of it overtaking one of the rally cars to get an idea how truly crazy that machine was: https://youtu.be/DDGbtUsTv24
That wasn't one of the rally cars, that was the lead rally car, going over 200 km/h over ungraded sand. One of my favorite points in motoracing history.
HP to weight isn't really useful beyond the point where you can put it to the ground. Notice how the truck is doing most of the gaining and overtaking in the rougher sections where it can keep better ground contact than the car.
