Solveig

The car built by the 2017 year’s team aimed to combine the speed of Magic along with the stability of Solbritt, in order to successfully compete with the top teams in the race. Further, the team expanded into two different divisions, management and engineers. The engineers could focus solely on building the best car possible, while the management team could focus on other important aspects. This was proven successful, as Solveig made it to 8th place in Bridgestone World Solar Challenge 2017.

Solbritt

Learning from past experiences, the new team aimed to build a more stable car for the 2015 competition. This resulted in Solbritt, our second generation car that finished the race at a 15th place out of 30 contestants. Not bad for a small team consisting of only 12 engineers doing everything from building the car to finding sponsors and marketing the project.

Magic

In the autumn of 2013, the JU Solar Team participated in the Bridgestone World Solar Challenge for the first time. The name of the car was Magic, and she was the first ever solar car built in Sweden to compete internationally. The team tried to push the limit by building the fastest car possible - an area in which they were successful. Unfortunately, though, the lightweight car blew off the road and did not cross the finish line.
