O. Bruton Smith

Chairman and CEO, Speedway Motorsports and Sonic Automotive
AGE: 81

Considering he's devoted his life to fast cars, it's not a surprise that Bruton Smith is constantly in motion. A NASCAR pioneer, Smith invested in racetracks before the racing league was even a blip on the map. Now his Speedway Motorsports (TRK) owns eight, including Texas Motor Speedway. And he's not slowing down. Today his focus has turned to fan experience, most recently adding amenities like luxury suites and pre-race entertainment at each of his tracks, as well as the opening of a state-of-the-art drag strip at his Lowe's Motor Speedway outside of Charlotte. If that weren't enough, he's also chairman of Sonic Automotive (SAH), which operates 182 car dealerships across the country. Smith has groomed his three sons to eventually take over the businesses, but he's not ready to call it quits just yet.
