The use of ultra- and super-high-strength steels contribute to safety and, at the same time, purposefully encapsulates the principle of lightweight construction.
The forces exerted in the event of a frontal impact are dispersed by a system of longitudinal and transverse members. Reinforcements in ultra-high-strength steel provide additional protection for occupants in the event of a side impact.
The concept also sees the use of multiphase steels. High strength and clearly defined deformability are two qualities that they have in common.
