Vehicle subframe
A system can include a subframe section having a first subframe portion and a second subframe portion. The second subframe portion can couple with the first subframe portion at an angled interface having an angle relative to a horizontal plane. The angled interface can decouple the first subframe portion from the second subframe portion and cause the first subframe portion to move in a direction towards the second subframe portion based on the angle of the angled interface in response to a threshold force applied to the first subframe portion.
