set and multiple additional planetary gear sets as well as at least four
torque-transmitting mechanisms that are selectively engagable alone or in
different combinations to establish a reverse electrically-variable
operating mode, at least three forward electrically-variable operating
modes, including two low range forward electrically-variable modes and a
high range forward electrically-variable mode.
