This year’s team focused their work on reliability and continuous improvement. The expectations were high for the second edition in London of the Shell Eco-marathon, because of the chassis based on the former H2Zero and some other new systems. We created a special PCB-design on the body to give a car a nice face. This design stands for innovation and we brought it with a full integrated dashboard on the steering wheel, a new ultra-efficient gearbox, an electronic managed clutch system and a real-time data system in the cloud.
At the day of the Shell Eco-marathon, things were running smooth. We passed as the first hydrogen team the technical inspection. This was a good start, because this results in more test runs. Unfortunately we needed the extra time because the optimal set up was not reached, yet. After three days hard work, it all came to the second race day. Everything had to run perfectly in order to set an ultra-efficient stint and we managed to do so! We were the best in our class and that resulted in winning the first place and having the most fuel efficient hydrogen car of Europe in 2017!
Another revision of the body has been made to make it stiffer and lighter. Also, the powertrain was adjusted this year so that just one wheel was driven instead of two, in this way a more efficient transmission can be achieved. In addition, this was the first team that participated at the EducEco. The purpose of this race was to practice driving strategy and to test the car well for the Eco Marathon, which was this year for the first time in London. The ambition of this team was to create a good foundation of a car where the next team could continue to optimize this. And finally, a result was obtained: a third place with a record of 890 km/l.
This year the largest team was active to design and make a completely new car. With many different disciplines, they have worked hard to create a beautiful car. This year, after a lot of research a whole new hydrogen system was introduced, with as a pièce de résistance: a custom-made fuel cell system, wherein the cells of the German ZBT are used. In addition, a new body has been designed such that the aerodynamics of the body are better. A long back side with a very small slope is used to make sure the air detaches as late as possible. Also this year no result was put down at the Eco Marathon despite the efforts, but the team did win first place in the battery electric category at the Challenger event in Rockingham, England.
This year, in addition to mechanical and electrical engineers, a chemical engineer and a health science student became part of the team. The aim was to expand the borders of the team even further to include almost all studies of the UT. It must be a university-wide team that offers students the opportunity to participate in an innovative, sustainable project in which one can put their newly gained knowledge into practice. This year’s work includes carbon rims to minimize the weight of the car, but despite that no result was put down.
The following year it was decided by the association that this success story should be continued. After recruitment in September 2012 the teams also consisted of the studies of Electrical Engineering and Advanced Technology. This multidisciplinary approach enabled to innovate on multiple fronts, with the aim of a more fuel efficient car! The entire electronic system is re-created that year and equipped with a CAN bus, which means that all the microcontrollers of the various components are on the same network and thus communicate with each other. This made it possible to also to start collecting data. The same body is rebuilt but this year with a lighter rib structure. The team improved the result for the previous year with a result of around 800 km/l, which led to the third place.
Green Team Twente begon in collegejaar 2011-2012 als een initiatief van W.S.G. Newton, de studievereniging van werktuigbouwkunde aan de Universiteit Twente. Zodoende bestond het team, toen een commissie van de vereniging, destijds volledig uit studenten Werktuigbouwkunde. Door middel van kennis, creativiteit en een enorme veerkracht wist het team een geweldig resultaat neer te zetten één jaar tijd. Dat jaar was het resultaat van 727 km/l zelfs goed voor een éérste plaats!
In the years 1978 to 1981, the so-called Shell Efficiency marathon took place in the Netherlands and even on the campus of the University of Twente. This is the precursor of today’s Shell Eco-marathon. The team from Twente won twice (1980 and 1981) back then with an amazing result of 783km/l. Here, however, the teams did not drive on hydrogen, but on gasoline.
