A student-built railroad car called Eximus IV has set a record at the annual Delsbo Electric contest for the world's most energy-efficient vehicles.
The Eximus team, who were the reigning champions from last year's contest, beat the tough competition to post an energy efficiency of 0.517 Wh/person-km.
The Delsbo Electric competition, which takes place in Sweden once a year, tasks students with building ultra-efficient battery-powered electric vehicles for a maximum of six passengers.
The competition specifically asks students to design their vehicles for rails so as to keep rolling resistance to a minimum. The competition has the separate designs take on a 2.1 miles(3.36 km) course using as little energy as possible.
After crossing the finish line, the energy used by each vehicle is then divided by the number of passengers on board.
