Bumper: Description and Operation

Bumper and Fascia Description

General Motors passenger vehicle bumpers are designed to withstand a collision into a fixed barrier at 8 km/h (5 mph). After absorbing the energy of the collision, the energy absorbers rebound to 80-90 percent of their original position. The energy absorbing capability of the front and the rear bumper systems is achieved through a honeycomb or a foam type energy absorbing structure in each bumper.


The following bumper fascias are made of urethane:

* The front
* The rear


Urethane withstands minor impact and returns to the original shape.

* The bumper
* The fascia


Be careful around the theft deterrent labels. For more information on the labels, refer to Anti-Theft Labeling (Anti-Theft Labeling) in General Information.
