1. An electrified powertrain that generates and transfers drive torque to a driveline of an electrified vehicle, the electrified powertrain comprising:
an electric drive module comprising:
a first electric motor having a first output;
a second electric motor having a second output; and
a planetary gear set having a sun gear fixed for rotation with the first output, a carrier fixed for rotation with the second output, at least two planetary gears rotatably disposed on the carrier, and a ring gear;
a driveline input gear that is driven by the ring gear and that delivers torque to drive wheels; and
a controller that controls operation of the first and second electric motors to alter a rotation of the ring gear that drives the driveline input gear based on operating conditions, wherein only the first electric motor provides torque input during a first cruise mode and wherein only the second electric motor provides torque input during a second cruise mode.
