One of the key societal challenges of today is the decarbonisation of the road transport.
In this context, the ERTRAC Strategic Research Agenda defines guiding objectives demanding by 2030 an 80 %
improved energy efficiency of the urban passenger transport and a shift to decarbonisation of the energy
needed. The challenging improvement of energy efficiency must be met by introducing advanced power train
technologies on the one hand and by significantly reducing the vehicles weight reversing the weight spiral
of the last decades on the other hand.
However, the acceptance of hybrid and fully electric vehicle (FEV) is defined by the customer's demand for
comfort, individuality and attractiveness (incl. operating range), safety and efficiency. Presently, the attractiveness
of those cars is significantly influenced by the purchase cost and most important by the range of the vehicle both
dominated by the underlying battery technology. To compensate for the additional weight of the battery and to extend
the driving range under electric driving conditions the overall vehicle weight must be reduced drastically. Any significant
weight reduction either allows for smaller and lighter battery systems at same range thus reducing the costs or increases
the range of the vehicle without increasing the weight and costs of the battery system. As stated by Volkswagen,
the electromobility amplifies the challenge in lightweight design for innovative vehicle concepts. The importance
of lightweight design increases by reason of the significant influence of the range of electric vehicles. Consequently
electric vehicles demand innovative vehicle concepts with significant weight reductions without penalties in comfort
(NVH), safety and costs.
