New megatrends in the automotive sector like alternative powertrains, autonomous driving or car sharing but also continuous improvements like increased safety regulations or CO2-emission standards can be influenced directly but also indirectly by an application-orientated selection of the used material or material combination. Thereby a new generation of material concepts can help to fulfil the partly divergent requirements and conflict of objectives consisting of strength, stiffness, energy absorption or lightweight. Further, the materials must be suitable for volume production and easy to integrate into established manufacturing processes like cold or hot forming and assembling, especially joining. Of course, new materials should be cost-effective, recyclable and completely simulatable.To reach those targets, material scientists have different approaches like developing a monolithic metal or a compound structure, varying by fundamental basics like alloying elements, microstructure, number of phases, homogeneity, anisotropy, cross-sectional profile but also layer set-up and order .The present paper takes up the mentioned diversity and introduces into different further developed material concepts which can be differentiated into opportunities for creating tailored properties of austenitic cold-hardening stainless steels, surface structured thin steel sheets and steel-polymeric composite structures. For every development, the focus is targeted to the combination of strength, stiffness and lightweight with the question how to increase every single value of the combination by using one of the new material concepts.The target application is thereby the field of alternative powertrains, especially the application area of electric mobility. Therefore, three different concept ideas are given for this strategic part of automotive development. One element is to use significantly cross-industry innovations to ensure a fast integration combined with reliable experience into this new application field.
