For 1990-2009 cars only

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

The following bumper fascias are made of urethane:

    â€¢ The front
    â€¢ The rear

Urethane withstands minor impact and returns to the original shape.

    â€¢ Bumper
    â€¢ Fascia

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