1. An electrified powertrain that generates and transfers drive torque to a driveline of a hybrid electric vehicle, the electrified powertrain comprising:
a first electric motor having a first electric motor output;
a second electric motor having a second electric motor output;
an internal combustion engine (ICE) having an ICE output;
a first planetary gear set selectively coupled for rotation with the second electric motor output, the first planetary gear set including a first sun gear, a first carrier and a first ring gear, wherein the first carrier is coupled to the driveline;
a second planetary gear set selectively coupled for rotation with the second electric motor output, the second planetary gear set including a second sun gear, a second carrier and a second ring gear;
an input split device comprising a third planetary gear set selectively coupled for rotation with one of the first electric motor output and the ICE output, the third planetary gear set including a third sun gear, a third carrier and a third ring gear; and
an ICE clutch that moves between an engaged position that couples the ICE output for rotation with the third carrier and a disengaged position that decouples the ICE output from rotation with the third carrier.
