An impact-absorbing system and method which assures speed dependency of loads generated in side members at times of frontal collisions, and reduces repair costs at times of low-speed collisions. A reinforcing member spans along a vehicle width direction in a substantially linear form between front ends of a pair of side members. A region of a rear wall portion of an impact-absorbing member, which region is disposed so as to connect between end portions of the side members, is provided with a plurality of protrusion portions which are spaced by a predetermined interval in the vehicle width direction, and includes grooves at outer peripheries of base portions of the protrusion portions. Peak portions of the protrusion portions include hole portions along a length axis of the vehicle.
