The theme of this article is related to the study of a light vehicle concept. A system with four electric motors in the wheel is used for propulsion. The vehicle has an energy storage system as well as a system of photovoltaic panels mounted on it. In a first phase, the research consists of calculating the vehicle chassis. Through simulation, the forces to which it may be subjected are verified, as well as the areas that require additional reinforcements by using specific materials. The study of the connections with the ground follows. The steering system is simulated, as well as the suspension systems. In parallel, studies are made through simulation on the external shape of the vehicle, taking into account the constraints related to: mass, access, visibility, the arrangement of solar panels on the surface of the vehicle, the energy efficiency of the assembly. The propulsion systems and the energy storage system, respectively, are input data for the analysis. These are calculated for a system of resistive forces that the vehicle design must respect and at the same time for the predetermined driving range.
