In AWD, power is transmitted to the rear wheels when the fronts lose grip. Having the front tires spinning is much less efficient, in terms of energy being used to propel the car forward, than having power shifted to the rears. Remember, too, that all the AWD driveline components are always turning, regardless of which wheels are doing the work.
