It's quite simple really.
Torque is a force. It is the rotational force applied to an object. Whether that be the wheels, gearbox input shaft or even just a bolt when you're tightening it up.
Power is a measure of work done and as such is a function of the force (torque) and the rotational speed:
Horsepower = Torque x Angular Speed
However when using RPM as a measure of speed it has to be converted, using RPM the equation is:
Hp = (T x RPM)/5252
The reason WRC cars have such high torque is because it allows them to have high power at low revs. This is due to the ~300hp restriction placed on them, so they produce around 3 bar of boost from ~2500rpm meaning that the 300hp is reached early in the rev range and maintained, giving them a very wide power band.
