The Shell Eco-Marathon is a competition for students, created by Shell, the British hydrocarbon energy company, and is held in the USA, Brazil, Europe and Asia. The challenge is to build the most energy-efficient vehicle. It seeks to transform the way mobility is viewed by allowing the use of alternative fuels, including electric or hybrid engines . For the team, competition is the opportunity to propose efficient transportation in daily trips in a congested city (home-work-home), where reaching high speed is a utopia, so, low consumption becomes more important in addition to mitigating the impact on the environment and resulting in an economic benefit. Therefore, for the selection of the vehicle's engine, the balance of weight-power-consumption was found in the existing engine options.
