It is more than a version of horsepower. Every time you try to change
direction in a car, your car has to fight the tendency for the larger mass
that is trying to go straight. This upsets your suspension geometry.
Unless you have the mythical perfect tires, it will fight against the cars
ability to keep them on the ground.
