Within the German Association for Research in Automotive Technology (FAT), all German car and commercial vehicle manufacturers, numerous suppliers and providers of mobility-related products and services have joined forces to conduct pre-competitive and collective research - under the roof of the German Association of the Automotive Industry (VDA). The focus is on sustainable mobility and energy concepts. The research results are used to derive basic principles that allow optimization of products and make innovations possible. In cooperation with research institutions, fundamental questions are being answered to respond to the ever-increasing demands on materials, environmental compatibility, automation and networking.
