2012 Mercedes Benz M-Class Crash Test

The front end structure, with its high energy-absorption potential, is essentially made up of the firewall and two lines of longitudinal members, anchored at the A-pillars. Two vertical members link the longitudinal members, which further increase deformation resistance. The necessary rigidity and strength of the floor assembly is provided by a robust structure made up of a separate center tunnel plus separate longitudinal members along each side, attached to the side wall. These are supported by cross members anchored to the floor as well as by a connecting member to the B-pillar as support for the front structure. The extremely robust side wall assembly comprises, quite apart from the longitudinal members described above and the side roof frame, A-pillars in a dual-casing design, internally reinforced with high strength steel. In a side collision, the cross member beneath the cowl, the cross member between the longitudinal members underneath the pedal floor, the high-strength-steel cross member beneath the driver's seat and the magnesium-alloy cross member underneath the instrument panel, as well as the front roof frame, ensure the highest possible stability of the occupant cell. The positioning of the fuel tank in front of the rear axle and of the filler neck over the rear axle increases the available deformation distance, maximizing the level of energy absorption in the event of a rear-end collision. This is achieved, above all, through the boxshaped design of the <b>...</b>
