A motor vehicle bumper system including a closed cross section impact beam having at least one open end and a reinforcing insert in the open end. The reinforcing insert has a central flat wall and a pair of flat, flexible wings attached to the central wall which cooperate with the latter in achieving energy absorbing performance similar to the more complex impact beam inserts having molded, egg crate-type constructions. The flat flexible wings and the central flat wall afford simple press-in installation and frictional retention in the open end of the impact beam.
