Hamilton felt win was possible before failure

Lewis Hamilton says he was confident he could challenge for victory in the Singapore Grand Prix before a loss of power forced him to retire.

The championship leader was running in fourth place having already pitted for soft tyres under an early safety car period, and keeping in touch with the lead trio of Sebastian Vettel, Daniel Ricciardo and Kimi Raikkonen. With the three ahead of him all on supersoft tyres, Hamilton says he was starting to believe he could win the race despite struggles for Mercedes all weekend.

“I was feeling super-optimistic in the car, I really was," Hamilton said. "The guys in front were on the option and I was on the prime and I was easily keeping up with the guys. I thought ‘you know what, we’ve got a race on our hands here’. The pace was nice, really under control.

"I was just waiting for that time when I could push and see what I could get from the car but obviously I didn’t get that. I lost power and I was hoping they would have a quick fix but it never came."

And Hamilton said he felt it was right to retire when he was sure there was no chance of scoring points due to his problem.

“I just lost power and they were telling me to make all these changes but nothing was making any difference. When I got overtaken by the Marussia’s [Manors] I knew really winning was out of the question. They started to pull away so I knew points would be out of the question.”
