I know what crumple zones are and usually they have nothing to do with the bumper itself. They're specific points on the frame and related structures that are designed to collapse in such a way as to absorb impact while still allowing as much kinetic energy as possible to travel around the cab (and also through passengers' femurs).
What we're looking at in the picture is just a bent bumper.
