Madison and Melanie Snow

Professional racing drivers keep getting younger and younger. Every year, Formula One, for example, seems to crown a new record holder for the youngest race winner in grand prix history, and almost as often, a younger-than-ever world champion. But this story takes the cake.

Madison Snow, you see, is only 15 years old. Too young, in other words, to get a driver's license. But when he does, he'll already be an old hand behind the wheel. That's because he just clinched the Gold Cup in the IMSA GT3 Cup Challenge. Behind the wheel of a Porsche 911 GT3 Cup, no less – and that's no easy car to control.

In fact he didn't just win the title, he dominated it: The series isn't even over yet, but after finishing second this week at Laguna Seca, he's so far in the lead that he's already got the championship in the bag and can "just have fun" at the Petit Le Mans at Road Atlanta next week. That would be enough to make any mother proud, but we have a feeling Madison's mom Melanie Snow – a past series champ herself, class winner at Sebring and part of the first all-woman team in the American Le Mans Series – must be beaming.
