For a relatively standard bumper beam structure, it should be able to effectively absorb energy from low-speed impacts through low-speed energy absorption boxes. The bumper beam is bolted to the vehicle body for easy removal and replacement.
Additionally, many models feature a foam buffer layer added to the bumper beam, which is very effective in collisions below 4 km/h. The foam buffer not only supports the outer plastic bumper but also mitigates impact forces, reducing damage to the plastic bumper and thereby lowering repair costs.
