They created the world’s most efficient, hydrogen powered, city car and are preparing a world record attempt

The Eco-Runner Team Delft 2022/2023 consists of 23 students of the Delft University of Technology who are ambitious to drive the transition for a sustainable future. The team is divided into 5 departments that work on different subsystems, to create one car together.

With the Eco XII the teams main focus was on reducing weight as much as possible. When the mass of the car is lower, it need less energy to drive. The Body department focussed on creating an aeroshell and a load-carrying structure that was as lightweight as possible without breaking.  
The greatest factor in limiting the weight of the car was creating carbon fibre parts for the parts that are traditionally made from steel. Examples would be the push rods in the steering system or the suspension beams.

Another factor of efficiency is limiting the energy losses within the car. These losses include rolling resistance, air drag, but also the losses that occur when converting hydrogen to electricity or converting electricity to kinetical energy (movement) in the electrical motor. To minimise these energy losses, the team designed and developed a new, custom-made electrical motor with an increased efficiency, and optimised the powertrain system with a brand new fuel cell.

The main challenge of this year’s team is driving more than 2056 km on just a little under 1 kg of hydrogen. During the world record attempt, the team members will drive for 3 days straight to cover this substantial distance. To achieve this goal, the team will travel to a test track with optimal conditions.
