Despite the disappointment of retiring from the lead in Singapore, Lewis Hamilton's fighting spirit was on display as he vowed to "keep pushing to the end".
Having clinched a dominant pole position on Saturday, the McLaren driver was cruising at the front of the pack on Sunday night, maintaining a comfortable 1.5 to two second lead over Sebastian Vettel.
However, disaster struck on lap 23 when Hamilton's MP4-27 suddenly slowed down, forcing him to pull over on the side of the track.
Shaking his head as he climbed out of his car, a dejected and frustrated Hamilton trudged back to the pits while Vettel went on to win the race ahead of Jenson Button and Championship leader Fernando Alonso.
"I'm okay now," Hamilton told reporters. "It was gutting when the car stopped, I was cruising.
"I was managing the gap and could have pushed more, I had the pace. I think today would have been an easy win.
"Nonetheless, that's not the case. The Red Bulls did a good job, Jenson too."
The 27-year-old's DNF, which came on the back of his third victory of the season at Monza, has dropped him to fourth in the Drivers' Championship, 52 points behind Alonso.
But with 150 still to play for, Hamilton is refusing to give up on this year's Drivers' Championship title.
"We've got six races left and I need to keep wishing.
"I need to win the rest of them.
"I won't give up, I'll keep pushing to the end.
"This makes it a lot harder, but as I said, we've still got six races to go."
Hamilton later took to Twitter, quoting the late Martin Luther King.
""The ultimate measure of a man is not where he stands in moments of comfort and convenience, but where he stands at times of challenge and controversy - Martin Luther King. Amen!!"
