Red Bull's Vettel wins Malaysian Grand Prix

World champion Sebastian Vettel continued his perfect start to the Formula One season by winning the Malaysian Grand Prix from pole position on Sunday.

Red Bull's Vettel, who won the season opening race in Australia two weeks ago, finished ahead of McLaren's Jenson Button in second and third-placed Nick Heidfeld for Renault.

"Fantastic job. In the heat we kept our heads cool. Thank you," Vettel told his Red Bull team over the team radio after winning his fourth race in a row.

"A pleasure every weekend to be with you. I'm loving it."

Vettel's team mate Mark Webber did well to claim fourth place following a poor start as both Red Bulls ditched the KERS boost system mid-race after suffering reliability issues.
