A drive unit includes a first electric machine including a first machine shaft, a second electric machine including a second machine shaft, and a differential interconnecting the first electric machine and the second electric machine. The differential includes a park gear. The drive unit further includes a single park system configured to engage the park gear of the differential to simultaneously stop rotation of both the first electric machine and the second electric machine. The park system includes a single pawl movable between an engaged position and a disengaged position. The pawl is spaced apart from the park gear of the differential in the disengaged position to allow the park gear to rotate. The single pawl is in contact with the park gear of the differential in the engaged position to preclude rotation of the park gear.
