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.

A video of how it works.

The figure on page 311 explains the torque split of a planetary differential (Old Ford with a front/rear torque split 34/66).

Hi OldF, yes I have seen one many many years ago, though they are not popular at all, but I found this scheme useful for visualizing the principal of asymmetric diff as it can be directly compared to a symmetric one.
