According to one embodiment, the invention provides for a light truck including a frame with opposing longitudinal frame rails running along each side of the vehicle. The frame rails include at least a leading portion with vertical placement lowered and selected to substantially align with a passenger car energy management structure. In this embodiment, the vertical placement of the leading portion of the light truck frame rails is selected to direct impact energy to a passenger car longitudinal energy management structure, improving vehicle-to-vehicle compatibility in the event of a front longitudinal impact with a passenger car. The present invention also provides embodiments which increase the impact energy absorption capacity of a light truck by providing geometric softening of the frame rails and material softening of the frame rails.
