Audi has a nice looking solution for torque split. This crown gear differential has a torque split front/rear = 40/60. The rear axle is rotated with a bigger diameter/radius than the front axle and therefore get more torque.
etc etc
Very interesting also. Somehow I doubt the center diff on WRC cars are viscous couplings though. They intuitively seem like a big wear point (but I could be wrong).
