Abstract: A body structure of a vehicle includes a bulkhead, and a frame rail extending forward from the bulkhead along a longitudinal centerline. A powertrain system is disposed laterally inboard of the frame rail relative to the longitudinal centerline. The frame rail includes a flared section, a splayed section, and a reinforcing member. The flared section curves laterally outboard, away from the longitudinal centerline. The splayed section includes a variable cross sectional area that increases with an increase in distance from the bulkhead. The reinforcing member is operable to increase lateral stiffness in the frame rail, in a direction transverse to the longitudinal centerline. The frame rail is operable to deform into contact with the powertrain system in response to a load applied to a forward end of the body structure and laterally offset from the longitudinal centerline, to generate a lateral force in the body structure.
