1. A transmission for a vehicle having a power source, the transmission comprising:
an input member for receiving power from the power source;
an output member for outputting power to at least one component of the vehicle;
at least one power split gear set having a plurality of members and operatively connected between said input member and said output member; and
an electromagnetic variator having a stator, an outer rotor, and an inner rotor;
wherein the inner rotor is at least partially received in the outer rotor and the electromagnetic variator is configured to provide variable torque transmission ratios between the outer rotor and the inner rotor; and
wherein said inner and outer rotors are each selectively operatively connectable to different ones of said plurality of members of said power split gear set by a plurality of selectively activatable torque transmitting units and are each selectively operatively connectable to the input member to be driven thereby by the plurality of selectively activatable torque transmitting units.
