Use of lightweight materials has played a significant role in reducing vehicle weight and in delivering high passenger cell safety standards, combined with a significant increase in strength. At the same time, these measures also help to ensure superior driving dynamics. Intelligent lightweight design is integrated into all areas of BMW vehicle development work and into all components, from the body and engine to the suspension. Materials used include high and ultra-high tensile steels, a hot-stamped B-pillar, plastics and state-of the-art composites. Increased use of aluminium components in the engine and suspension systems has also further reduced the weight of the relevant assemblies.
