A resilient bumper assembly suitable for use on a motor vehicle. The bumper assembly includes a rigid backing member and a substantially hollow elastomeric outer shell. A plurality of walled elements extend from the inside surface of the front portion of the elastomeric outer shell rearwardly toward the backing member. The walled elements have one end adjoining the remainder of the bumper shell and the other end open. The walled elements each circumscribe a void. The free end of each walled elements is engageable with the backing member to absorb energy upon impact. When the front portion of the outer shell and the backing member includes openings aligned with the volume circumscribed by the walled elements, passages are then defined which permit the flow of cooling air through the bumper assembly.
