A vehicle frame structure includes a longitudinal floor frame member and a frame stiffener connected with the floor frame member. The floor frame member connects with a vehicle floor panel to form a substantially closed cross section. The floor frame member includes a lower wall including a lower section, a higher section, and a transition section disposed between the lower section and the higher section. The lower wall transitions upward along the transition section from the lower section to the higher section. The frame stiffener connects with the floor frame member on an exterior of the floor frame member. The frame stiffener has a substantially U-shaped configuration in cross section and includes a bottom wall that is vertically offset below the lower wall of the floor frame member at least along a portion of the transition section.

The structure of claim 1, wherein the longitudinal floor frame member is generally U-shaped in cross section and includes an inner side wall, an outer side wall, the lower wall interconnecting the inner side wall and the outer side wall, an inner flange extending inwardly away from the inner side wall and an outer flange extending outwardly away from the outer side wall, wherein an uppermost surface each flange is configured to contact and connect with a lower surface of the floor panel. 3. The structure of claim 2, wherein the frame stiffener includes an interior side wall connected with the inner side wall of the longitudinal floor frame member, an exterior side wall connected with the outer side wall of the longitudinal floor frame member and the bottom wall interconnecting the interior side wall and the exterior side wall. 4. The structure of claim 3, wherein a width of the bottom wall measured in a transverse direction between the interior side wall and the exterior side wall is less than a width of the lower wall measured in the transverse direction between the inner side wall and the outer side wall. 5. The structure of claim 4, wherein the interior side wall includes a diagonally angled section extending between a substantially vertical section of the interior side wall and the bottom wall. 6. The structure of claim 5, wherein the diagonally angled section tapers downwardly and outwardly from an inner lower corner of the longitudinal floor frame member toward the bottom wall. 7. The structure of claim 3, wherein each of the inner side wall and the outer side wall includes a substantially vertical upper section, a substantially vertical lower section offset horizontally from the upper section and a tapering transition section interconnecting the upper section to the lower section. 8. The structure of claim 7, wherein each of the interior side wall and the exterior side wall includes a substantially vertical top section, a substantially vertical bottom section offset horizontally from the top section and an angled transition section interconnecting the top section to the bottom section, wherein the upper section of each side wall contacts a respective top section of a respective interior wall, wherein the lower section of each side wall contacts a respective bottom section of a respective. 9. The structure of claim 1, wherein the bottom wall of the frame stiffener contacts the lower wall of the floor frame member near a forward end of the frame stiffener and a rear end of the frame stiffener. 10. The structure of claim 9, wherein the transition section disposed between the lower section and the higher section is a forward transition section, wherein the floor frame member includes a rear section and a rear transition section disposed between the higher section and the rear section, wherein the lower wall transitions downwards along the rear transition section from the higher section to the rear section. 11. The structure of claim 10, wherein the bottom wall of the frame stiffener contacts the lower wall at the lower section and the rear section. 12. The structure of claim 1, wherein the frame stiffener includes a rear trailing arm mount opening configured to receive a rear trailing arm mount. 13. The structure of claim 12, wherein the frame stiffener includes a forward end and a rear end, the rear trailing arm mount opening is located nearer the rear end as compared to the forward end. 14. A vehicle body structure comprising: a vehicle body including a floor panel and defining a sliding door opening;a longitudinal floor frame member connected with a lower surface of the floor panel to form a substantially closed cross section, the floor frame member including a lower wall including a lower section, a higher section and a transition section disposed between the lower section and the higher section, wherein the lower wall transitions upwards along the transition section from the lower section to the higher section, and at least a portion of the transition section is positioned in a longitudinal direction between a forward edge and a rearward edge of the sliding door opening; anda frame stiffener connected with the floor frame member, the frame stiffener having a substantially U-shaped configuration in cross section and including a bottom wall that is vertically spaced from the floor frame member at least along a portion of the transition section. 15. The structure of claim 14, further comprising a rear trailing arm mount connected with the longitudinal floor frame member and the frame stiffener includes an opening through which the rear trailing arm mount extends. 16. The structure of claim 14, wherein the lower section of the lower wall of the longitudinal floor frame member is positioned in front of the higher section in the longitudinal direction. 17. The structure of claim 16, wherein the bottom wall of the frame stiffener includes an upwardly sloping portion that slopes upwardly and rearwardly. 18. The structure of claim 17, wherein the lower wall includes a rearward transitioning section where the lower wall transitions downwardly from the higher section toward a generally horizontal rear section, and the bottom wall of the frame stiffener contacts the lower wall of the longitudinal floor member at the generally horizontal rear section. 19. The structure of claim 18, wherein the bottom wall of the frame stiffener is offset below the lower wall of the longitudinal floor frame member between the transition section and the rear section.
