MEXICO CITY (AFP) - Sebastian Vettel vowed to go all out for victory in Sunday's Mexican Grand Prix, regardless of Lewis Hamilton's progress, after he claimed his 50th pole position on Saturday (Oct 28).

The four-time world champion admitted he made some important to changes to the set-up of his car and expected to have strong race pace.

"The championship is not in my control as much as I would have liked it to be," said Vettel.

"It depends on Lewis.

"So, for us, we go all out and I think we deserve a good result. Let's see what we can do tomorrow.

"Yesterday, it wasn't that good for us, but we improved overnight and all our changes worked. So we should be good for race pace."

Vettel will have Dutchman Max Verstappen alongside him at the front of the grid, after the Red Bull driver produced a dazzling show of fast laps at the Autodromo Hermanos Rodriguez.

Hamilton, who needs to finish in the top five to take his fourth title, qualified third in his Mercedes ahead of his team-mate Valtteri Bottas.

Vettel's success ended Hamilton's run of three consecutive pole positions, but the Briton said he remained positive that he can mount a bid to in Sunday's race.

"If I get a good start, I promise I will go for it," he said.

"It is a long run from the start down to the first corner so it may be the best chance to overtake.

"It will be a bit of a train in the race and it will be a one stop-strategy, so it's important to take any chances. I need to get close enough for the pit-stops.

"I gave it everything for pole, but I couldn't do it. They were just quicker than us."

Hamilton delivered a promising run with full tanks in a race simulation on Friday, but said he expects a very close fight with both Vettel and Verstappen.

"I want to try and win and take the championship from the top step if I can, that is the right way to do it," he added.
