Shell organizes three competitions all over the world every year since 1985. This includes the competition in North America, the shell Eco-marathon Americas in Detroit; in Asia the Shell Eco-marathon Asia in Singapore and the European Shell Eco-marathon in London. Each of these race have the same car classes. All the competitions are about the efficiency: use as little fuel as possible at a given track.
These competitions take place as part of an overall sustainability event organized by Shell. Here, the newest technologies of sustainability will be shown, including the cars of the Eco-Marathons as a highlight.
The two main classes are the Prototype and the Urban Concept class. At one side the prototype cars are about the ultimate performance. At the other side the Urban Concept cars are more focused at the design and use. This involves the development of the car of the future.
Among these two main classes, the different fuels are divided in multiple sub classes. For example, there can be driven on conventional gasoline and diesel, ethanol, GTL, hydrogen and accumulators.
Green Team Twente is participant in the Urban Concept class where it drives on hydrogen. The team wants to carry out the message that hydrogen is the fuel of the future by developing the city car of the future driving at hydrogen.
Each team has multiple attempt to set the best result on the track of London. This track of the Shell Eco-marathon 2017 will be 1659 meters long. Each team must drive ten laps in a time of 39 minutes. At the end of every attempt, the consumed fuel will be measured. The most efficient car wins the competition.
During the competition, two parts are important. First, the fact that the cars of the Urban Concept class have to stop fully and then pull again. In addition, there is a bridge in the track. This slope determined for a large part the parameters of the car, number of motors, battery size and the gear transmission.
Various teams of different classes drive at the same time on the track. Wondering how the competition goes? See it here:
