torque is the angular analog of force applied in your example and power of course is the analog of power in your example and rpm is the analog of linear velocity in your example

Note that the torque(force) is decreasing from ~5k rpm yet the power is increasing from that point to ~6200rpm. Why? because the hp is the product in the mathmatical sense of the decreasing force(torque) and increasing rate(rpm)


BTW there are many concepts in Physics that go against intuition, among the most bizarre at the macro scale is exhibited by a simple toy, a spinning top.
That's not a Carrera, 210 HP is Honda minivan type numbers :-)
