Eco-Runner X

This year the Eco-Runner will take on the challenge of competing in the Urban Concept class. In this class, certain requirements are set which steer the vehicles in the direction of modern city cars. In contrast to the Prototype class, in which the goal was to be as efficient as possible without any sort of restriction, the Urban Concept class will assure that the teams design and build an energy-efficient vehicle that has familiar road car features. The most important requirements in the Urban Concept class are listed hereunder in order to give a feeling of how the car will look like when it is fully assembled.

  • The vehicle should have four wheels.
  • The outside of the vehicle should have windscreen wipers, front- and backlights and a tow bar.
  • The inside of the vehicle should contain a luggage compartment and should include FIA-approved seat belts.
  • The driver should sit straight up and should have a 180 degrees view on the road.

The race itself in the Urban Concept class competition is also different from the Prototype class. The race focuses on “stop and go driving” to imitate the behavior of city cars. After each round, the vehicles have to come to a complete stop after which they have to accelerate to obtain their most efficient velocity again. At the end, the goal is still to be as energy-efficient as possible in order to win the race.

We took all these requirements and rules into consideration and are currently developing the most energy-efficient city car in the world.


At the beginning of March, our focus was to finalise the production of the Eco-Runner X. After the lamination of the vehicle’s body by our production engineers, our partner KVE took the effort to cure the different parts in their oven while making sure the body maintains the desired properties. Once the different parts arrived back in the D:DREAM Hall, our engineers worked hard on assembling the body of the vehicle. Due to our engineers’ dedication and hard work we have now finalised the production of the car’s body, including the newly installed windows and safety belts. The steering system has a perfect fit and works as desired.

We also received the in-wheel electromotor from our partner Advanced Electromagnetics (AE Group). The motor plays a crucial role in the vehicle’s powertrain, as it converts electrical energy into kinetic energy which drives the Eco-Runner X forward. The motor will be tested thoroughly at a later stage, making sure it meets all efficiency and safety requirements. We thank AE Group for another great year of collaboration!

The next production goal is to assemble the rest of the Eco-Runner X by integrating the powertrain, the braking system, suspension, wheels and electronics into the body of the vehicle.

The making of the Eco-Runner X depends on a combined effort between our predecessors, our current team and our partners. Together we hope to fulfill our goal to produce the world’s most efficient hydrogen-powered city car.
