A futuristic Dutch family car that not only uses the sun as power but supplies energy back to the grid was hailed as "the future" Sunday as the World Solar Challenge wrapped up.
The innovative bi-annual contest, first run in 1987, began in Darwin a week ago with 41 vehicles setting off on a 3,000-kilometre (1,860-mile) trip through the heart of Australia to Adelaide.
Dutch car "Nuna 9" won the race for the third-straight time, crossing the finish line on Thursday after travelling at an average speed of 81.2 kilometres per hour (55.5 mph).
It was competing in the Challenger class, which featured slick, single seat aerodynamic vehicles built for sustained endurance and total energy efficiency.
But there was also a Cruiser class, introduced to bridge the gap between high-end technology and everyday driving practicality.
