Crash Safety of Primarily Sandwich-based Vehicle Body Designs

In the Next Generation Car project, the DLR Institute for Vehicle Concepts has developed a vehicle concept based on the L7e category with a body weight of just 90 kg. The structural concept consists largely of hybrid materials in sandwich construction. The article presents the results of the crash tests of two car bodies.
A very lightweight L7e class vehicle, which has low rolling resistance and drag, and thus low energy consumption, is being developed as a research demonstrator as part of the Safe Light Regional Vehicle (SLRV) subproject within the Next Generation Car (NGC) research project. Given that up to two-thirds of a vehicle's energy requirements are driven by weight , low vehicle weight is a key factor in achieving low energy consumption. Despite a target range of 400 km, the vehicle is being designed as a fuel cell hybrid to achieve a low weight for the energy storage system. Capable of a maximum speed of 120 km/h, it is intended to have two seats and a luggage compartment.
