This cover is usually painted and matched with the car’s color but the actual bumper is located behind this front cover. The front bumper assembly also comprises of the panels around its edges sometimes that help it to further blend with the car’s body. Also, the front bumper assembly consists of shock absorbers.
As the front bumper is the foremost part of the car, it has to be able to withstand the most impact during a collision. And although the front bumper assembly also contains the lighting circuits for the car, it’s because it is fitted with shock absorbers and given a unique shape that it is able to withstand a lot of pressure and keep its components safe in a regular collision.
The bumper cover is likely what you would view as the bumper. It's the fiberglass piece that gets scratched up or cracked in an accident. There is structural support underneath the cover that is designed to absorb impact, this is the actual bumper. As long as there is no damage to the structure beneath all you need is the cover.
