Then as they accelerate off the line they must transfer all torque to the rear wheels as weight shifts off the front wheels.
So the AWD car just locks the center diff as the front wheels lift off the ground giving all the torque to the rear wheels.
Now both cars are on equal footing (RWD only), except NOW the AWD car is carrying all that extra weight of the AWD system for no additional advantage
