An apparatus includes a drive shaft, a transmission, a motor shaft, and an engine shaft. The drive shaft includes a plurality of drive gears and is configured to transmit power to a wheel of a vehicle. The transmission includes a first transmission shaft including a first transmission input gear and a first plurality of output gears and a second transmission shaft including a second transmission input gear and a second plurality of output gears. The first transmission shaft includes a first shifting element configured to selectively engage an output gear from the first plurality of output gears to adjust a ratio between a shaft rotation speed of the first transmission shaft and a shaft rotation speed of the drive shaft. The second transmission shaft includes a second shifting element configured to selectively engage an output gear from the second plurality of output gears to adjust a ratio between a shaft rotation speed of the second transmission shaft and a shaft rotation speed of the drive shaft. The output gear from the first plurality of output gears is operably coupled to a drive gear from the plurality of drive gears such that power is transmitted between the first transmission shaft and the drive shaft when the output gear from the first plurality of output gears is engaged with the first transmission shaft via the first shifting element. The motor shaft is configured to be coupled to a motor. The motor shaft has a first motor gear and a second motor gear. The first motor gear is operably coupled to the first transmission input gear. The engine shaft has an engine gear and is operably coupled to the second transmission input gear and the second motor gear of the motor shaft.
