Lewis Hamilton has vowed to "hold nothing back" in the 2016 season's final four races as he attempts to overturn Nico Rosberg's points lead and win a fourth world championship.
The defending champion heads into the closing six weeks of the season requiring a big swing in points between himself and Mercedes team-mate Rosberg after a turnaround in fortunes since the summer break.
A run of four victories in five grands prix means Rosberg leads the standings by 33 points and the German driver can afford to finish second to Hamilton in each of the final four races to become world champion for the first time.
With the mathematics now not in his favour, Hamilton says all he can do is perform at his best - starting at the United States GP this weekend, a race which is live only on Sky F1.
"We've got four races left to make the most of it and that's exactly what I plan to do," he said.
"It's just about hitting every race weekend as hard as I can, going all out for every win and seeing what happens from there. I'll be holding nothing back out there."
Hamilton's form and mindset have been placed under heavy scrutiny in the media since Rosberg's latest win in the Japanese GP. A fallout with the British press over so-called 'SnapchatGate' was followed by another poor start in the Suzuka race, which effectively ended his victory hopes immediately.
A foot injury sustained while training then ruled him out of last week's Pirelli tyre test at Barcelona, although the world champion's participation in Austin has not been in question.
But although on a season-worst run of five races without a win, Hamilton has only once been defeated in five appearances at the US GP with a record-equalling victory on his radar in the Texan capital this weekend.
"[America] is like a second home race for me these days," he said. "I love the country, the culture, the people and the track, so I can't wait to get started. I've got some great memories from Austin, with three wins from four races and, of course, the title win last year.
"That was one of the highlights of my career, no doubt. It's almost like the American fans have adopted me as their own, so I'll try to channel all of that positive energy into this weekend."

With the all-Mercedes duel for the Drivers' Championship entering its most critical phase, team chief Toto Wolff has reiterated their desire to ensure the outcome is not decided by mechanical failures or errors.
"The title is purely between them, which is fantastic news for the team as we can be happy whatever the final outcome," said Wolff, after the remaining would-be challengers to Rosberg and Hamilton officially dropped out of contention at Suzuka.
"However, the pressure is on to ensure that their battle is decided man-to-man, and hopefully wheel-to-wheel, on the race track. We may already have celebrated our championship success as a team - but we have a responsibility to the drivers and will not let anything distract us from the job at hand."
