There was plenty of exultation, of course, in the Mercedes garage after they won the constructorsâ€™ championship for the first time.
They went into the race needing 25 points to make sure of the team title and scored a maximum 43. They also took another hefty stride towards the individual prize.
Hamilton became one of only four drivers to win nine races in a season. For the second time in a year he has also won four races in succession, equalling the achievement of Michael Schumacher in 2004. His 31st victory pulled him level with Nigel Mansell as Britainâ€™s most successful F1 driver. He is going from strength to stranglehold in this world championship and if he does not win the thing it will be a travesty.
Hamilton has won five more races than his sole rival, his team-mate Nico Rosberg, but leads by only 17 points with that ridiculous and possibly championship-spoiling, double-points season-ender in Abu Dhabi next month.
Rosberg, though, provided the outstanding drive here. He drove 52 laps on the same set of medium tyres to take second place,more than 13sec behind Hamilton.
Hamilton, starting from his seventh pole of the season, defended his advantage by cutting across Rosberg, but the German drew level and then moved slightly ahead of his great rival. But as he did so he locked up and flat-spotted his tyres, forcing him to pit for fresh rubber on only the second lap.
When he asked about strategy he was told he would probably have to finish the race without making another stop. He not only finished it but made up 21 places, getting annoyed on separate occasions near the end, when he was expected to come in for another change. It was an astonishing performance in view of the fact that some drivers had to make two stops and others struggled to get to halfway without coming in for a change.
Rosberg, who appears to have been in decline during Hamiltonâ€™s recent onslaught, was phlegmatic enough after his costly error. â€œIt was just a mistake on my side,â€ he said.
â€œI just braked too late, that was it. It was very unnecessary. It was my corner and I am very disappointed with that. After that my tyres were square so I couldnâ€™t see where I was going and had to pit.
â€œI thought that was the end of the day, so partly Iâ€™m happy to have managed to get back all the way to second. In hindsight, I could have pushed more during the race. Itâ€™s always easy to know more afterwards. In the end my tyres were fine. It is a pity. I just messed up. Very simple explanation â€“ I braked too late and too hard.â€
It was also a good afternoon for Valtteri Bottas, in his Williams, who took his fifth podium position of the season to go fourth in the title race behind Daniel Ricciardo.
Bottas said: â€œThe beginning seemed to be very good and I was not far off from Lewis and everything was going to plan. The tyres were feeling good and suddenly the rear tyres started to go, started to lose pace and I was struggling more and more and Lewis was getting far away.
â€œThen we stopped for the prime [medium tyre] and it took just a really long time to get it to work. It was weird.â€
But the Williams performance chief, Rob Smedley, said: â€œValtteriâ€™s always very good at being self-critical and trying to look inward, which is a hugely commendable attribute that he has as a racing driver, but I think the reality is he was beaten by a much, much quicker car.â€
Jenson Button was fourth, one place ahead of his team-mate Kevin Magnussen, as McLaren continued their impressive weekend in Russia, positively effulgent by their recent modest standards.
Button was cautious about describing McLarenâ€™s result as a turning point. â€œSome of it is the circuit, but also I think we have improved the set-up of the car and we have found some other things that work for us,â€ he said.
â€œWeâ€™ll see when we get to Austin [on 2 November]. I look forward to seeing where we stand. The Tarmac is very similar to here, just a lot more traction zones. To finish fourth is the best result weâ€™ve had in a little while, but you still want more. You are disappointed because you want to be on the podium.â€
