Audi Lunar Quattro
Built to compete for the $30 million dollar Google Lunar XPRIZE, the Audi Lunar Quattro is the first four-ringed vehicle not meant for terrestrial use. To complete its mission, it'll have to traverse at least a half kilometer of rocky lunar landscape, while beaming high-res images and video back to Earth. During the journey, which will take an estimated five days, it will need to hitch a ride on a rocket, and deal with temperatures as high as 250º F. In order to overcome these challenges, it's built from a mix of high-strength aluminum and magnesium, uses a pair of stereo cameras to navigate obstacles, has a swiveling solar panel to charge up the battery powering its four hub motors, and, of course, takes full advantage of Audi's legendary all-wheel drive system.
