Lando Norris won the Sao Paulo Grand Prix after new world champion Kimi Antonelli spun out of the lead in slippery conditions at Interlagos.
Antonelli had jumped pole-sitter Norris during a damp start but fell apart after his stop for dry tyres and ended the race fifth.
Max Verstappen pulled off a typically-brilliant comeback drive from 21st on the grid to finish second, ahead of Red Bull team-mate Isack Hadjar.
George Russell‘s podium hopes were undone by a staggering spin in the pit-lane exit, recovering well to fourth, while an extraordinary start from Lewis Hamilton from the back of the grid only earned him ninth.
Mercedes clinched the constructors’ title, a week on from Antonelli celebrating his drivers’ crown.
Norris masterfully claimed pole in soaking conditions on Saturday afternoon, pipping Russell to top spot – before his compatriot’s five-place grid drop for an engine penalty.

Russell was furious with Mercedes after believing their order for him to abort his final flying lap cost him pole.
Norris was joined on the front row by the man who deposed him as champion.
The Italian had a moment of fortune as he made his way to the grid, skidding across the grass and narrowly avoiding the barriers before hauling his Mercedes out the mud.
Behind them was a jumbled-up order – Liam Lawson third, Nico Hulkenberg fourth ahead of Hadjar and Ollie Bearman.
Antonelli jumped Norris on the short run down to turn one. The McLaren man was then undone by Lawson at turn two.
Hamilton began 20th after engine woe on Saturday, with Charles Leclerc 14th after his own penalty.

The seven-time world champion was in familiar company, joined by Verstappen in 21st – who won this race from 17th in the rain in 2024.
Hamilton soared up to ninth by the end of lap one, steaming down the outside off the line past a string of cars, including team-mate Leclerc.

The Ferrari war was back in the spotlight on lap ten as Leclerc cruised up to Hamilton – who was complaining about his tyres.
Neither driver gave an inch as Leclerc made his move but Hamilton appeared to have taken life out of wheels as the Monegasque got the move done. To add insult for Hamilton, he was then breezed past by his old foe Fernando Alonso in the lowly Aston Martin.
Hamilton wanted dry tyres but Ferrari wanted to wait. Out front, Antonelli had stormed eight seconds clear with Norris now back in second and Russell up to third.
Hamilton pulled the trigger on the soft tyres on lap 15 and was motoring as the pack followed suit.

But there was a twist in the tale as the heavens opened again. Russell pitted first and gained ground but Hamilton spun down the main straight, clipping the barrier, as he made his way in.
Russell was now on the back of Antonelli – who will be investigated for an unsafe pit release – and the world champion was told to let his team-mate through.
Norris held firm to claim back-to-back wins in Sao Paulo, crossing the line 14.6 seconds ahead of Verstappen.
