Advanced body structure: The uni-body construction of the R-Class uses advanced technology and robust materials to create a virtual fortress for the vehicles’ passengers. High Strength/Low Alloy steel is used in strategic areas and accounts for more than 60% of the body structure. 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.
12-way air bag protection
An advanced system of 8 air bags offers 12-way occupant protection. Dual two-stage front air bags, front and 2nd-row side-impact air bags, and window curtain air bags for all three seating rows are standard.
