The Eximus IV, a student-built railroad car that has been setting records for fuel efficiency since 2016, has once again proven itself the world’s most efficient vehicle in the annual Delsbo Electric contest.
Every year, teams from all around the world travel to a specially-built track in Sweden to test their ultra energy-efficient vehicles designed to cover the longest possible distance on as little fuel as possible. Contestants are tasked with driving their vehicles on a 3.36 kilometer rail track to keep rolling resistance to a minimum, while carrying a total of six passengers, with an average weight of 50kg per person. Ever since it entered the competition four years ago, the Eximus IV has become somewhat of a legend of the competition, and this year it once again proved why.
