Engineers have spent a great deal of time thinking of ways to protect passengers during all phases of a crash. Their proprietary 360 degree safety system was designed to promote a secure environment during all times surrounding this type of incident. It starts with high strength steel being implemented in various body areas, including a steel cross beam that is welded across the floor of the Acadia between the B pillars. The lower engine compartment rails have also received some additional reinforcement to protect the motor. The lower center of gravity provided by the wide stance helps to give this vehicle greater stability as well.
This special material is first formed in the paint oven using special process which make it easier to form, provides greater strength and can absorb the energy of a crash even better than the standard high strength steel that have been used in previous models.
There are also 6 standard air bags that come standard in the Acadia: 2 dual stage air bags for the front seats, 2 seat-mounted side impact air bags for the first row and 2 head curtain side impact air bags that effectively cover all 3 of the seating rows. The last type are among the longest ever produced for a production vehicle of any kind.
Augmenting the air bags is the proprietary rollover sensing system which has been designed by GMC to activate the air bags automatically if the sensors determine that a rollover is about to happen. They also stay inflated longer to provide the extended protection that is necessary for an incident of this type.
