A bumper assembly includes an elongated beam and a pair of crush cans. The elongated beam includes a plurality of reinforcing walls extending horizontally that define a gap in a central portion of the beam. The pair of crush can assemblies is attached to the beam at transversely spaced locations relative to the central portion of the beam. The central portion of the beam is structured to have less bending resistance than the right and left sides. The reinforcing walls span the crush can assemblies so that the gap facilitates bending the central portion of the beam. A method of making a bumper is also disclosed that includes the steps of selecting a bumper beam and partially removing an upper/central portion and a lower/central portion of the bumper beam.
