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:
an electric motor having a rotor shaft that extends on opposite ends of the electric motor and includes first and second pinion gears fixed on opposite ends of the rotor shaft for rotation thereon, the electric motor providing a torque split on opposite ends thereof;
a transfer shaft that includes first and second transfer gears meshed for rotation with the first and second pinion gears, the first and second transfer gears providing a first gear ratio reduction from the first and second pinion gears;
a final drive pinion gear fixed for rotation on the transfer shaft; and
a final drive ring gear meshed for rotation with the final drive pinion gear and providing a second gear ratio reduction from the final drive pinion gear to the final drive ring gear, the final drive ring gear driving a differential that in turn drives first and second output shafts.
