1. A drive system for a vehicle for variable distribution of torque, from a primary input and secondary input, between a left wheel and a right wheel of a vehicle, the drive system comprising a first and second torque output shaft, one for each of the left wheel and the right wheel, an open differential, and independently controllable first and a second clutch packs, configured such that:
torque from the primary input is transferred to each of the torque output shafts via the clutch packs;
torque from the secondary input is transferred to each of the torque output shafts via the open differential;
torque from one output of the open differential is summed with torque from one clutch pack output in the first torque output shaft; and
torque from another output of the open differential is summed with torque from the other clutch pack output in the second torque output shaft;
wherein the drive system, further comprises a secondary input gear set configured to change a rotation speed of the source of secondary input before entering the clutch pack; and
wherein the secondary input gear set is a compound planetary gear set, wherein the source of the secondary input drives a sun gear of the compound planetary gear set, and the output of the compound planetary gear set that is a planet carrier of compound planetary gear set transmits torque to an input of the open differential.
