The Fastest Solar Car In The World

This is the Nuna4, which won the World Solar Challenge in Australia — the fourth time in a row the University of Delft has won the race. The Nuna4 weighs less than 190 kg (without driver), and its lightweight construction means it can get up to an average speed of 90.87 km/hour. Image by Erik Van 'T Woud/AFP/Getty Images
