Lewis Hamilton's title hopes were dealt a blow when his engine failed in Malaysian Grand Prix.
Lewis dominated the race until flames started pouring from his Mercedes on lap 43.
Nico Rosberg finished third to extend his lead in the championship to 23 points with five races to go, and 125 points available.
Daniel Ricciardo beat Max Verstappen in a Red Bull one-two.
After the race Lewis Hamilton spoke with Radio 5 live's Tom Clarkson: "My question is to Mercedes. We have so many engines made, but mine are the only ones failing this year.
"Someone needs to give me some answers because this is not acceptable. We are fighting for the championship and only my engines are failing. It does not sit right with me."
