Nuon team's Nuna 9 car has taken victory in the race from Darwin to Adelaide for solar-powered cars.
The team from the Netherlands crossed the finish line in Adelaide on Thursday, clinching a seventh victory in the World Solar Challenge with chief engineer Marten Arthens describing it as the "best feeling ever".
"We're going to celebrate but first I'm going to take a shower. I haven't done that a week.
"After that we're going to go and drink some beers."
But first, the team took the now traditional dip in the Victoria Square fountain as supporters cheered them.
The University of Michigan crossed the line second about an hour behind the Dutch with Belgium team Punch Powertrain close behind in third.
Nuon led the field for most of the 3000 km journey from Darwin.
The team is made up entirely of students from the Delft University of Technology who design, build and race the cars.
They battled bad weather and heavy cloud during the five-day race to finish with an average speed of just over 81km/h, down from 92 km/h when they last won in 2015.
Esta Dyngenouts, mother of technical manager Steven, said the group had all been working extremely hard.
"I am a very proud parent because my son has become such a mature guy who can do things like this," she said.
The leading Australian car, Red Swift from Western Sydney University, is currently in sixth place but still has over 400km to cover before reaching Adelaide.
The World Solar Challenge is one of the world's leading races for solar cars and the 2017 event marked the 30th year since the first race in 1987.
