The Shell Eco-Marathon is all about efficiency. The competitors need to race the most kilometers using the least fuel. During the race the hydrogen level is measured to see how much fuel is used. In combination with the raced distance can be measured how much kilogram hydrogen is used per distance. The results will be converted to gasoline and presented on the scoreboard. Of course, the team with the least usage wins! All teams are batteling a heavy fight on innovation. They show the world how far the technology is with alternative fuels and the possibilities of the automotive section.
Classes and rules
The Shell Eco-marathon has two different classes: the 'Urban Concept' class and the 'Prototype' class. In the first class, where Hydromotive is competing in, there are more rules to keep in mind. This way, a scenario that is simular to the real world is created.
The rules of the Urban Concept class is a small book of 47 pages. Some rules are a matter of course, while other rules change the design of the vehicle completely. For example, the car needs to have two doors, whereas last year one door was sufficient. The maximum weight of the vehicle without the driver is maximum 225 kilogram. The driver needs to weigh at least 70 kilogram. If he or she weighs less, the car needs to have extra ballast.
Furthermore, there are requirements to the size of the vehicle. The maximal length is 3500 mm, the width needs to be between 1200 and 1300 mm. The heigth can be a little tinier: 1000 to 1300 mm. The car need to be 100 mm of the ground.
This year, the tires of the car are different than last year: motor tires are not allowed any more. The tires should have a flat profile, so they are simular to cars who are driving on other fuels.
To guarantee the safety of all competitors during the race, there are safety requirements. A driver must be able to get out of the car within ten seconds. A hydrogen gas detector need to be installed in the back of the car to warn the team about possible hydrogen leaks.
