P1racenews AI automatic summary:
For the first time across the opening 21 rounds of the F1 season, all 10 teams are united on an important factor early in a weekend.
None of the 10 teams in Formula 1 has revealed car updates to the FIA for the São Paulo Grand Prix at Interlagos, marking the first time this season.
Teams are expected to make adjustments to their packages in Brazil, following the previous round in Mexico City where cooling was crucial, but no new visible components will be seen on the grid at Autódromo José Carlos Pace.
As the focus shifts to the 2026 regulations overhaul, fewer teams are bringing upgrades in the latter part of the season.
Only a handful of teams introduced changes at recent races, with Red Bull planning potential adjustments to the RB21 to help Max Verstappen close in on the championship leaders.
Going forward, any further updates to the cars will have to wait for the final three rounds of the campaign.
