Second, they are very light
Third, they have incredible gearing and sticky tires so the energy transfer is high
Fourth, they have incredible RPM, so the power is distributed over a very wide range. It is a question of rate of work.
I will certainly agree that the rate of work of an F1 car exceeds that of a truck. But an F1 car could not pull a trailer.
Gearing and HP determine the rate of work.

) The statement that I was disagreeing with earlier was:
Torque accelerates cars, not HP. HP is about top speed.
The S2000 is a very good demonstration of this fact; it manages good acceleration despite only producing middling torque.

First, you are wrong - they do not make negligible torque - it is around 280-300 pounds of twist.
