The previous two events have drawn some big names from within Brazil and around the world. Last year Michael Schumacher took victory from a 25-kart grid that included his former teammates Massa and Barrichello, as well as drivers from all manner of racing, both closed wheel and open (and even just two). Although Massa says interest in the event has skyrocketed, he's determined to "prioritize quality over quantity" and keep it to 25 or 26 karts.
