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 coupled to a first output shaft that drives a first drive wheel, the first output coupled to the first output shaft through a differential;
a second electric motor having a second output selectively coupled to a second output shaft, the second output coupled to the second output shaft through the differential; and
a clutch having a first multi-plate clutch and a second controllable one way clutch (COWC), wherein the clutch moves between:
a first position that decouples the second electric motor from the second output shaft, wherein in the first position drive torque is provided to the first and second drive wheels exclusively from the first electric motor, wherein in the first position the first clutch is closed and the second clutch is free rolling; and
a second position that couples the second electric motor to the second output shaft, wherein in the second position the first and second electric motors drive the first and second drive wheel through the differential, wherein in the second position the first clutch is open and the second clutch is locked; and
a controller that controls operation of the clutch based on operating conditions.
