Hartley made it through to Q2 for Toro Rosso but an engine failure meant he was unable to complete a lap in the session, and a penalty for taking on new elements dropped him to 17th place.
Hamilton appeared to smash into longtime rival and nearest challenger in the world championship Vettel while jostling for position on the first corner. He was very non-plussed about it as if he's on this planet and on the grid to win races. Looking at podiums, race wins, pole positions and titles, what sort of company is he keeping? Sunday, Hamilton survived an early scare to wrap up the title in Mexico after contact on lap 1 with Vettel left him with a flat tire.
It was clear that the Renault engine was particularly vulnerable in these conditions and perhaps explains why Red Bull were frantically calling Max Verstappen and telling him to slow down and stop setting fastest laps! "The pressure is off so we should be able to perform better than we ever have and I believe we can".
One person who couldn't wait to congratulate Hamilton was his PSG-striker pal Neymar.
"Lewis has been much more consistent - not that he was inconsistent before - but he has shown his highest level of consistency this year of all the years he has been driving in the sport", he said. To have become the first team in F1 history to defend its titles over a regulation change is seriously impressive, let alone that it clinched both championships with races to spare.
Come qualifying on Saturday and the race on Sunday, Verstappen was just stellar.
"He had such a rough summer", Horner added.
"I am enjoying the fight with him".
"I now look forward to the next couple of races, hopefully things will go smoother, I get to the end of the race and see where we end up!"
"Honestly, it doesn't feel real man. I mean, obviously, that's not the kind of race that I want - when you're 40 seconds behind or something - but I never gave up and that's really, I guess, what's important, what's in my heart". Alonso wasn't having it though, and pushed Lewis wide, causing bits of bargeboard to fly as the two made contact. In the end, he won it by more than 19 seconds, anyway.
Records are the easy way to try and make an argument for how good a driver is, but in one sense records can be misleading.
But 2017 was the most surprising of them all.
F1 fans were treated to a battle they will hope to see again and again next year, as Alonso and Hamilton went wheel-to-wheel (not once but twice) in the closing stages.
But when the reality is that it is all over a measly ninth place, it's a little more underwhelming. You have got for sure a potential world champion with Max and he is only going to get stronger with age.
He joined Vettel and Alain Prost as four-time world champions. As Hamilton was winning, rival Vettel was struggling.
"What a season it's been. I want number five now but you just take it one step at a time".
Indeed Hamilton has four titles, taken in four ways, in four countries, under three regulation sets.
You can never definitively name the greatest of all time.
