1. An e-axle assembly for an electric or hybrid vehicle, comprising:
a housing extending from a first housing end to a second housing end to define an internal compartment;
a single electric motor disposed within said internal compartment and including a stator and a rotor rotatable relative to said stator about an axis;
said rotor extending between a first rotor end and a second end and defining a hollow extending internally and continuously within said rotor between said first and second rotor ends;
a first gearing mechanism and a first shifting actuator operably paired with one another and disposed within said hollow adjacent said first housing end and a second gearing mechanism and a second shifting mechanism operably paired with one another and disposed within said hollow adjacent said second housing end;
said rotor operably connected to and driving a differential arranged centrally within said hollow to present a first differential side facing said first housing end and a second differential side facing said second housing end, wherein said first gearing mechanism is operably connected to said first differential side of said differential via a first gear shaft and said second gearing mechanism is operably connected to said second differential side of said differential via a second gear shaft; and
a pair of output shafts each operably connected to a respective one of said first and second gearing mechanisms and extending outwardly from respective first and second housing ends of said housing for sending torque to wheels of the electric or hybrid vehicle.
