A hybrid bumper system includes a polymeric reinforcement beam with end sections and structural covers attached to the ends sections to considerably strengthen the end sections. Bracketry stably supports the reinforcement beam on a vehicle frame. A fascia covers at least part of the reinforcement beam but leaves a portion of the structural covers in a visible position. The structural covers are treated for aesthetics, such as by painting, chroming, or other surface treatment. In one aspect, the beam includes a molded polymeric beam component, structural L-shaped covers attached to its end sections, and a tie bar along it rear side that stiffens and rigidifies a center of the polymeric beam component. In another aspect, a tow bar or rail-to-rail metal reinforcement beam front system (or rear with tow bar) is incorporated.
