Hamilton started the race at the Circuit of the Americas in fifth but was leading going into the final stages of the race. However, his teammate, Valtteri Bottas overtook him for the victory on fresher tyres but P2 was still enough to crown Hamilton a six-time World Champion.
Hamilton dedicated his victory to Niki Lauda who sadly passed away in May. The Austrian former World Champion is credited with bringing Hamilton to Mercedes.
“I wouldn’t be here’s without so many of you, my amazing family – especially my dad who taught me to never give up, my friends, my team at @mercedesamgf1 and my fans," Hamilton said on Twitter.
“You’ve been with me on this journey from the start and it’s because of you that I stay focused and determined. I’m forever grateful from the bottom of my heart for every single one of you for your constant support, encouragement and love.
“This season is for Niki Lauda, my incredible friend and mentor who we lost this year, who proved that courage and determination go hand in hand.
“This one’s for you, Niki. I’ll continue to make you proud.”
