The reduction of the vehicle mass is an important point in order to reach new milestones in reducing fuel consumption and emissions. Today's and future steel structure concepts still shows lightweight potential. But even more attractive potential for lightweight body in white structures could be realised by new multi material design concepts. The DLR (German Aerospace Center) Institute of Vehicle Concepts and Meridian Technologies Inc. are working on innovative and cost attractive magnesium A-pillar solutions. By using the topology optimisation a new design idea for the A-pillar area was found. This new design concept offers the possibility to integrate additional functions. The new design shows expedient crash behaviour. A developed solution has a weight benefit of more than 50 % compared to a steel reference structure. Because of functional integration the magnesium part is very cost attractive. To achieve the requirements of corrosion prevention Magnesium parts need to be proper designed. Within the example of a serial production Front End Carrier (FEC) possible solutions will be shown.
