In just one short year, Austin's new COTA track ranks among the most popular circuits in the world. Built in time for the inaugural Formula One race here last November, the track – from its wild elevation changes to chicanes and switchbacks – is something to behold. Since opening, the site has been host to many high-powered events – from F1 to MotoGP, from races on bicycles to races on foot. Even though the COTA has been named by the city of Austin as a Green Business Leader for 2013, concerns linger about bringing motorsports to environmentally conscious Austin. But consider this: Developing a world-class track attracts not only the racing of today, but the industry innovators looking for a greener tomorrow.
