Lewis Hamilton believes the supreme reliability of his Mercedes car this season was a key factor in his world title win.
The Briton held off Ferrari's Sebastian Vettel to equal the German's tally of four drivers' championship wins after an enduring battle this term.
Hamilton insists the W08's near-perfect reliability record has made all the difference for Mercedes in 2017.
"Where we normally run in our best mode I got to run in that a lot longer, basically," he told Sky Sports.
"What it really showed is what HPP [Mercedes High Performance Powertrains] have done with our power unit. I was just visiting the guys just recently to say thank you to them."
Hamilton is the only driver on the grid to finish every race this season and will become just the second world champion since 1963 to go through a title-winning campaign without a DNF if he finishes Sunday's season-ending Abu Dhabi Grand Prix.
"To have the consistency and reliability we've had this year has enabled us to be where we are. It's been the outlier of us alongside Ferrari, for example, and I'm massively grateful for that," he added.
Hamilton has finished ninth in Mexico and fourth in Brazil recently as he battled to close out his title win.
With that pressure now off, he wants a tenth race win of the season to sign off.
"We could have won the last race fairly easily and it was solely my fault that we didn't do so," he said.
"The plan this weekend is to go back to our old performance hopefully, Austin kind of thing where we are solid weekend, that's our goal this weekend.
"To make sure we start on the right foot and continue all through practice. It's a lot easier said than done, but not impossible. The goal is to try and finish the season on a high."
Hamilton is 2.00 to win the Abu Dhabi Grand Prix, where Vettel is 8.00. The world champion is 2.87 to set the fasted lap and win Sunday's race.
