Abstract
A vehicle underbody including a rear underbody structure, a rear differential, a sub-frame, and a traction battery is provided. The rear differential is mounted to the rear underbody structure. The sub-frame is mounted to the rear underbody structure rearward of the rear differential. The traction battery is mounted between the rear underbody structure and the sub-frame. A base portion of the traction battery defines a base portion plane that does not extend through the rear differential. The sub-frame may include at least two reinforcement members each having a ramp-shaped end extending toward the rear differential. The sub-frame may include a rear lateral member and a trailer hitch mount extending rearwardly therefrom. One of the reinforcement members and the trailer hitch mount may be aligned in parallel with a central longitudinal axis defined by the rear underbody structure.
