FIA Sets Two Straight-Mode Zones for Brazilian GP
The FIA has confirmed two straight-mode zones for the upcoming Brazilian Grand Prix at Interlagos. This decision follows a varied season of SM zone allocations across different circuits.
As Formula 1 heads to Brazil, the FIA has announced that two straight-mode (SM) zones will be in effect at the Interlagos circuit for the weekend's Grand Prix. These zones are part of the active aero system that replaced the previous DRS setup for the 2026 season. Unlike DRS, active aero gives drivers control over both front and rear wings to minimize drag on straights, while still ensuring downforce in corners.
The number of SM zones has fluctuated throughout the season, tailored to each track's unique demands. For instance, Australia and Singapore each had five zones, while Monaco saw none. At Interlagos, the first SM zone will be on the start-finish straight, and the second between Turns 3 and 4. The detection point for overtaking will be after Turn 12, with activation following the kink of Turn 13.
In a broader view of the season, Mercedes is on the verge of clinching the constructors’ championship, needing to outscore Ferrari by just three points in Brazil to seal the deal. Meanwhile, Kimi Antonelli recently made history by becoming the youngest F1 world champion, securing the title at the Mexican Grand Prix. McLaren's Lando Norris won the Brazilian race last year, while George Russell was Mercedes' last victor at Interlagos in 2022.
For those keeping track, here’s a quick rundown of SM zones at various circuits this season: five in Australia and Singapore, four in places like China and Austria, and none in Monaco. Brazil joins the list with two SM zones for this weekend's event.
