We have Front bumper and Rear bumper.
Main function: Both of them are for absorbing impact by reducing bodily damage/injury during an accident.
Car bumper system has three main components; the fascia, beam, attachment brackets and sometimes energy absorber.
The fascia is the outer cover. It is attaches to the quarter panels and rear end panel. The energy absorber attaches to the beam. The beam is mounted directly to the vehicle body.
