The goal of this work is to optimize an automotive chassis for a 3 wheeled hybrid vehicle. This vehicle is intended for touristic and low speed performance, 2 of the more relevant features are, that the vehicle has 3 wheels and that it is battery powered by 7 cells which are distributed under the driver seat and the first line of seats. Therefore, the vehicle has to be very light but still strong enough to endure the daily loads it is driven into. In order to obtain the final topological region an improving process in the topological region's geometry was needed, starting with regions with 30 mm element's size to 16 mm element's size, so the available equipment could compute the optimization in similar amounts of time. Topological optimization is used to acquire a very close shape to the optimal one for structural problems design from a conceptual viewpoint.
