2010 Mercedes-Benz GL550 SUV Body Structure

The uni-body construction of the GL-Class SUV uses advanced technology and robust materials to create a virtual fortress for the vehicles’ passengers. High- Strength/Low-Alloy steel is used in important areas of the vehicle. Roof pillars employ three layers of steel, and doors feature steel crossbeams. Full-width front and rear crossmembers, along with a reinforced floorpan and door sills, combine to provide protection in a variety of impacts. Advanced front and rear crumple zones progressively deform to help absorb the energy of an impact, while underhood components are staggered to help prevent them from stacking up in a frontal impact, thereby reducing the likelihood of intrusion into the cabin. An ellipsoidal front bulkhead helps channel some of the forces of a frontal impact under, over and around the passenger cabin.

There are 9 air bags that offer 13-ways of occupant protection. Dual two-stage front air bags, front and 2nd-row side-impact air bags, a driver’s knee air bag, and window curtain air bags for all three seating rows are standard.
