Dalarna University’s Eximus IV, the 2019 Delsbo Electric winner, has yet again achieved a new world record in Energy Efficiency for electrified vehicles.
According to the Delsbo Electric’s CTO professor Henrik Rödjegård, the 2020 Eximus IV can – in theory – transport a person nearly halfway around the world using the energy contained in just one liter of petrol.
The latest stats prove that the new world record for the world’s most energy efficient transportation of a person is now 0.517 Wh per person per km.
With this, the Eximus IV team has broken their 2019 world record of 0.603 Wh per person per km.
According to Delsbo Electric, the Eximus IV team went to extreme lengths to secure the world record.
During the first race lap, the vehicle had a spike in consumption. By analysing and comparing Delsbo Electric’s open source data from 2019 and 2020, the team could isolate the peak at a particular spot along the tracks.
After physically measuring the tracks they found an 8 mm difference in distance between the rails and adjusted the Eximus IV wheelbase to achieve the historical result.
According to Delsbo Electric, the whole length of the track is covered by a network capable of sending video and a constant flow of data from the vehicles.
This advanced measuring equipment tracks vehicle data 2.000 times a second and pushes it online every second.
Delsbo Electric will add additional data points; such as wind- and temperature sensors along the track to facilitate the development of more advanced automated systems that can react in advance to changing conditions.
Delsbo Electric is a competition in energy efficiency where teams design and drive rail vehicles with a maximum of six passengers.
All participating vehicles are revolutionary; each of the vehicles in the competition consume less energy than ordinary headlights in a car.
On the bylines, the HHK Innovation Award went to sister vehicle Eximus V for being the first ever team to use automated driving in the competition.
