A hybrid vehicle has a torque distribution drive mechanism comprising a first planetary gear set 24 coupled to a first output shaft 18 of an input differential 12 and a second planetary gear set 26 connected to a second output shaft 20 of the input differential 12 and the first planetary gear set 24. An auxiliary drive member, e.g. electric/hydraulic motor 22, is coupled to the first or to the second planetary gear set 24, 26 and induces an offset torque to the first and second output members 18, 20 thereby providing torque vectoring and active yaw control. The first and second gear sets 24, 26 are coupled by common planetary carriers 28, 30 having planet gears 44, 46 which engage with sun gears 32, 36 and ring gears 34, 38. Ring gear 34 is driven by the motor 22 and ring gear 38 is fixed to a base member. The motor 22 is adapted to vary magnitude and direction of the offset torque.
