Vettel takes record ninth victory in a row

Red Bull's Sebastian Vettel wrapped up the Formula One season on Sunday by winning the Brazilian Grand Prix and becoming the first driver to take nine successive victories in a single year.

The sport's youngest quadruple world champion, still only 26, also matched fellow German Michael Schumacher's 2004 record of 13 wins in a season.

"Guys, I am so proud of you. I love you. Remember this, enjoy this moment. Yes. We did it. This is unbelievable," said Vettel, his voice wavering over the team radio after he took the checkered flag for his 39th career win.
