A vehicle body structure includes a pair of floor frames, a pair of auxiliary frames, and a pair of side sills disposed in juxtaposition about a longitudinal central axis of a vehicle body and arranged in the order named in a transversely outward direction of the vehicle body wherein the auxiliary frames have front ends spaced rearwardly, by a predetermined distance, from rear end portions of a pair of side outriggers. A front portion of the vehicle body located forwardly of the front ends of the auxiliary frames has less rigidity than a rear portion located rearwardly of the rear ends of the auxiliary frames. The vehicle body structure thus constructed can effectively absorb the energy of a crush or collision while maintaining a certain degree of rigidity. The side sills are each composed of a box-shaped hollow member containing therein an elongated reinforcing member. The reinforcing member has a front end substantially aligned with the front ends of the auxiliary frames in the transverse direction of the vehicle body so that the rear section of the vehicle body located rearwardly of the front ends of the auxiliary frames has an increased degree of rigidity.
