The goal of the LIghtweighting Technologies Enabling Comprehensive Automotive Redesign (LITECAR) Challenge is to identify conceptual solutions that are beyond the state-of-the-art in the area of (but not limiting to) advanced materials, structural design, advanced manufacturing, and energy absorbing mechanisms to enable future lightweight and safe vehicles. LITECAR is not looking for incremental improvements but pioneering solutions to tackle this problem. Participants are encouraged to comprehensively redesign the entire vehicle prioritizing lightweight and safe designs.
