Sao Paulo, Brazil:Lewis Hamilton of McLaren became Formula One's youngest champion after finishing fifth in the Brazilian Grand Prix on Sunday.
Felipe Massa of Ferrari won on Sunday in front of his home crowd, but it wasn't enough to erase the seven-point lead Hamilton held entering the season-ending race.
Hamilton needed to finish fifth or better to win the title at age 23, and he did just that after overtaking Toyota's Timo Glock on the last lap. Fernando Alonso won the 2005 title for Renault at age 24.
Hamilton fell to sixth place after being overtaken by Toro Rosso's Sebastian Vettel with two laps to go, but the Briton recovered to move up one spot and finish the season with 98 points, one more than Massa.
