2015 Mercedes-Benz S-Class Body Structure

Aluminum and high-strength steel body structure

So what is different about the body structure in the 2015 Mercedes-Benz S-Class? Greater use of aluminum helps the body shell of the S-Class elevate its overall rigidity, occupant protection and acousting qualities while reducing weight. Along with high-strength and ultra-high-strength steel, advanced lightweight materials such as extruded and cast aluminum, diecast magnesium, metal-polymer hybrids and high-density foam in the roof pillars enhance body strength while cutting excess mass.
