This thesis is the outcome of the activities carried out since July 2023 to the present day in Team H2politO, a team made of students with the aim to design, build and optimize low consumption prototypes in order to participate every year in an international competition, the Shell Eco-marathon. Every technical choice and each component, from mechanics to electronics, derives from a wide collaboration between the team members. The main soft skills that group all of them are the passion and the willpower of defining a target and trying to reach it just with their own forces. A consistent personal growth is therefore experienced putting together different ideas and discussing technical solutions in order to reach the final target: obtain the lowest possible fuel consumption at the Shell Eco-marathon.
