Brazil

Norris controls a rain-hit Brazilian Grand Prix with the right call for intermediates at the end, Verstappen climbs from 21st to second and Mercedes take the constructors' title off the podium. Ferrari, from overheated intermediates to cold slicks and a missed final stop, have another wet-weather day to forget.

Full wets return for the first time in a year as Norris takes pole in a chaotic, rain-soaked qualifying. The data shows Russell was the fastest driver of the day until Mercedes aborted his decisive Q3 lap, while Ferrari's wet performance was better than the result suggests and penalties reshuffle the grid for a wide-open race.

Verstappen changes his entire power unit and both Ferraris take a new combustion engine, while Hamilton's FP3 ends in smoke and a full power-unit change that sends him to the back of the grid. On track, Verstappen beats Antonelli by 25 thousandths using his electrical deployment, and Leclerc asks for a huge front-wing change to find grip.

Kimi Antonelli sets the pace in FP2 at Interlagos, with Mercedes looking strong and Ferrari struggling for straight-line speed, energy deployment and overall balance. The long runs point to high tyre degradation, while rain could completely reshape the weekend.
