Abstract: A drivetrain for a powertrain system is arranged to transfer mechanical power between an internal combustion engine, an electric machine and a driveline. The drivetrain includes a gearbox including an input member disposed on a first end, an output member disposed on a second end and an auxiliary geartrain including a first mechanical drive mechanism, a second mechanical drive mechanism, and an auxiliary driveshaft. The auxiliary driveshaft rotatably couples the first mechanical drive mechanism and the second mechanical drive mechanism. The electric machine includes a stator attached to the second end of the gearbox and annular to the output member of the gearbox. The second mechanical drive mechanism is rotatably coupled to the rotor of the electric machine. The first mechanical drive mechanism is rotatably coupled to the input member of the gearbox. The internal combustion engine is also coupled to the input member of the gearbox.
