New transportation energy efficiency record set in Sweden

Delsbo Electric is an annual contest in creating energy-efficient rail vehicles. This time, a new record was set by students from Dalarna University and Chalmers University of Technology.

Teams wishing to participate in the competition had to create rail vehicles operating on electric batteries. Only teams whose vehicles could cover a distance of 3.36 km without losing any battery charge had any chance of winning the competition.

This is the fourth time in a row that the same team wins this competition, building increasingly efficient vehicles with each entry. Their latest electric vehicle is called Eximus IV. Compared to last year’s entry, this vehicle has better aerodynamics, it is made up of different materials with improved engine and wheels.

The vehicle spends just 0.603 Wh of energy to transport its driver across a distance of 1 km. The only drawback is its speed: the vehicle hardly outpaces a bicycle, so it’s too soon to talk about any practical application for this invention.
