Lewis Hamilton acknowledged his stunning fightback victory at the Sao Paulo Grand Prix felt as good as his first in Formula One.
The Mercedes driver saw his Friday qualifying session result ruled out due to a DRS infringement, meaning he started the sprint race in last, but went from 20th to fifth, only for a five-place grid penalty to mean he started 10th on Sunday.
However, the Briton delivered a memorable win, gaining eight places early on and overtaking Max Verstappen with 12 laps remaining.
The reigning world champion cut Verstappen's lead in the battle for the title to 14 points with three races to go.
"It feels like a first as I haven't had a win for a long time," Hamilton said.
"I never thought we would close the gap like we did today when things just seemed to be going against us.
"It just shows you should never give up whatever you are facing. You need to keep pushing, keep tumbling and never ever stop fighting. That's what I have done this weekend.
"The team did an amazing job and Valtteri Bottas did a great job to [finish third and] get as many points as possible.
"I just pushed as fast as I could, but from last on the grid and another five-place penalty this is my hardest weekend I have had [this season]."
Hamilton has now won 17 races in the Americas (seven in Canada, six in the United States, two in Brazil and two in Mexico).
It means he overtakes the legendary Michael Schumacher as the driver with the most F1 victories across the four nations.
He dedicated the victory to his father Anthony and to the Brazilian fans who supported him at Interlagos.
He added: "My dad reminded me of when I was in F3 in Bahrain around 2004, when I started last and finished first - so this one is for my dad.
"I am so grateful for the incredible support I have had this weekend. I have not had this much support since Silverstone, and since then it has been really difficult.
"To hear these fans throughout the weekend has been humbling. I have been saying 'obrigado Brasil' because I am so grateful."
Next up is the Qatar Grand Prix and Red Bull driver Verstappen vowed to finish the campaign strongly as he eyes his first F1 title.
He said: "We tried everything we could today, it was a good battle but at the end we missed a little pace. But it was good fun.
"We still have a decent lead so today was a bit of damage limitation. I'm confident, in the coming races we will come back stronger."
