Red Bull’s Max Verstappen won his first Formula 1 world title in dramatic circumstances at the season finale in Abu Dhabi.
His rival Lewis Hamilton had appeared in control of the race, despite controversy on the first lap, until a late safety car.
The race was restarted with one lap to go with Verstappen on fresh tyres and Hamilton on old ones and the Dutchman swept by to win the race.
It was in many ways a fitting way to end one of the greatest and most contentious seasons in Formula 1 history – and the arguments over right and wrong will rage for some time to come.
At the end of the race, while Verstappen screamed with delight and Red Bull celebrated, Hamilton sat in his Mercedes for several minutes, disbelieving at the way events had turned against him in the final minutes.
How an historic title decider unfolded
The 36-year-old had appeared to be in control of the race only to be left powerless to retain the lead.
The race had appeared to surrender to Hamilton after he was allowed to keep the lead he had earned with a better start than Verstappen despite going off track to retain his position when the Dutchman tried to pass him at the end of the first back straight.
Hamilton was imperious from then on, through a pit stop and a virtual safety car, until Nicholas Latifi crashed his Williams with five laps to go.
Mercedes felt they could not afford to pit Hamilton because to do so would have been surrendering the lead if Verstappen did not do the same – and he may well not have done because his tyres were relatively fresh after a second stop.
But when Hamilton did not stop for fresh tyres, Verstappen did and that was the decisive call.
There was more controversy as race director Michael Masi initially said lapped cars between Hamilton and Verstappen would not be allowed to un-lap themselves, as is normal practice.
Red Bull complained and Masi changed his mind, which put Verstappen right behind Hamilton for the one remaining lap of racing.
Verstappen passed Hamilton into Turn Five and held off his attempts to re-pass down the two straights that followed and completed the lap before erupting with joy.
Yet whatever anyone’s view of the various incidents in the race, few would begrudge Verstappen the title after a season in which he and Hamilton have gone toe-to-toe throughout in one of the most remarkable F1 seasons there has ever been.
First-lap drama as well
At the same time, it was a fitting way to end a season that has been characterised by on-track clashes and off-track arguments between Hamilton, Verstappen and their teams.
The race unfolded as the season has, with Hamilton and Verstappen in a race and league of their own, and for a long time the year’s destiny appeared to be heading towards Hamilton.
There was drama from the opening lap, after Verstappen made a poor start from pole position, Hamilton an electric one from second on the grid, and the Mercedes was ahead before the first corner.
Verstappen tracked him through the first few corners, slipstreamed him down the long, first back straight and dived for the inside into the chicane at Turns Six and Seven.
Verstappen got down the inside of Hamilton but went in deep to the corner, his speed carrying him to the outside kerb long before the second right-handed part of the corner.
Hamilton avoided him, as he has so many times this season, and cut across the chicane, retaining the lead.
He slowed a little over the rest of the lap to give back the advantage he considered himself to have gained, and the arguments started on the pit wall.
Verstappen said over the radio: “He has to give it back.”
Red Bull radioed race director Michael Masi to insist that Verstappen was “ahead and stays on track”.
Masi replied: “He has forced him off. All the advantage was given back before the end of the first lap.”
The officials decided that no investigation was necessary and when Verstappen was told of the decision he said: “That is incredible. What are they doing there?”
The recriminations will doubtless continue for some time, especially as Verstappen came into the weekend complaining that he was being treated differently than other drivers by the stewards after the controversial Saudi Arabian Grand Prix last weekend, and Red Bull have been ratcheting the tension between the teams with a series of controversial claims in the media.
Hamilton had the race – until luck intervened
On track, though, the fundamental truth for much of the race was that once Hamilton had got by, he and Mercedes simply had too much pace for Red Bull and Verstappen, as they have for the last four races, all of which Hamilton has won to close a 19-point gap and claim the title.
Red Bull threw everything they could at Hamilton.
After Hamilton and Verstappen pitted for fresh tyres, they left Perez out and ordered him to hold Hamilton back.
Hamilton passed Perez down to Turn Six on lap 20, but was then re-passed down the next straight.
Perez was then ordered to “back him up” through the marina section of the track, and Verstappen closed what had been an 8.7-second deficit to 1.7 by the time Hamilton finally passed Perez a lap later.
But Hamilton eased away again, until a virtual safety car deployed to clear the stranded Alfa Romeo of Antonio Giovinazzi gave Red Bull an opportunity.
They pitted Verstappen for fresh tyres, hoping to come back at Hamilton over the final 20 laps.
But so strong was Hamilton that Verstappen was able to make only minimal inroads into his lead, and the race appeared to be over until the late drama snatched it from Hamilton’s grasp.
