Perpetual motion anyone?
The thing is that if you go down hill with the engine still connected to the drivetrain you will be slowing down (unless you are on a really steep hill) and at some point fuel will be needed to maintain idle which will be the slowest speed you can go down the hill with the clutch engaged and no brakes.
Power, whether measured as HP, PS, or KW is what accelerates cars and gets it up to top speed. Power also determines how far you take a wall when you hit it
Engine torque is an illusion.
