An electrified powertrain that generates and transfers drive torque to a driveline of an electrified vehicle is provided. The electrified powertrain includes an electric drive module (EDM), a driveline input and a controller. The EDM includes a first electric motor, a second electric motor and a planetary gear set. The planetary gear set has a sun gear fixed for rotation with an output of the first electric motor, a carrier fixed for rotation with an output of the second electric motor, at least two planetary gears rotatably disposed on the carrier and a ring gear. The driveline input gear is driven by the ring gear and delivers torque to drive wheels. The controller controls operation of the first and second electric motors to alter a rotation of the ring gear and drive the driveline input gear based on operating conditions.
