The Delft University of Technology-based team has competed eight times. The University of Michigan team's car, Novum, finished an hour later, with Belgium team Punch Powertrain close behind in third place.
Nuon team engineer Marten Arthens described the win as the "best feeling ever." "We're going to celebrate, but first I'm going to take a shower. I haven't done that in a week," Arthens said. The Michigan team has competed in 12 Australian races since 1990.
This year's race attracted 95 teams from more than 20 countries. It marks 30 years since the first World Solar Challenge in 1987.
