How I like to put it: ultimately, HP gets a load up a hill (as per Newton). Torque is simply a way of making hp, via rpm.
But if an engine ONLY has torque (2000 lb-ft @ 150rpm), it's getting nowhere fast.
Another law of physics: you can always CREATE torque with gearing, but you cannot create more power.
You just made two opposing statements, first is Torque is a way making HP through RPM.
The second, you can create Torque through RPM and gearing.
The second is true.
Which part is opposing?
Torque must have rpm to generate hp. Torque alone is a measurement of force. HP is a measurement of power.
Power = force x velocity (speed)
To climb a hill, you need a certain force at a given speed, which equals power. Torque is not part of the equation.
