E very two years, driving teams from around the world meet in Australia for a grueling, 1,877 mile race straight through the heart of the country’s most oppressive terrain. The twist? Each vehicle is powered entirely by solar energy.
This is the premise of the World Solar Challenge, won this year by a team from the Netherlands’ Delft University. In the gallery above, see the unique cars and drivers who raced in this year’s event.
