Engine horsepower and wheel horsepower are not the same thing. An engine with high horsepower and less torque would need to have a transmission that could put that kind of power to the wheels. Besides, with all the computer controls, even the most reckless Cadillac owner would have whatever horsepower and torque the car is capable of “handled” for them.
Having spent a good part of my life around race trucks and having built several ground up/frame off vesicles, including the engines, I am aware of the details ;)
And anything in the neighborhood of 400 HP is a lot of power regardless of the computer wizardry. You still have to steer the thing and 400 gets you into the ‘oh sxit’ range of the speedometer faster than many are able to deal with.
