Maybe you saw him still with Scuderia Torro Rosso back in 2007 & 2008. Since 2009 Red Bull is a top team & Vettel is driving there. In 2009 Brawn's team (former Honda, currently Mercedes) beated them with Button getting the title. Last year Red Bull was the best with both Vettel and Webber winning a lot. Because of many mistakes and internal fights McLaren & Ferrari could still fight for the title, but Vettel won it in the last race.
