Around 70 percent of all the bodywork panels are made from state-of-the-art, high-strength steel alloys that minimise weight and maximise safety. These steel grades also play a key role in protecting the occupants in the event of a side impact. The quadruple-skinned B-pillars and the side members, which absorb the bulk of any side-impact forces and channel these forces into the body structure, are made partially from ultra-high-strength, hot-formed high-tech steel.
