FIA Locks In Two Straight Mode Zones for Austin as Active Aero Makes Its COTA Debut

Formula 1's active-aero era reaches the Circuit of the Americas this weekend with a bit of regulatory clarity. The FIA has confirmed that drivers will get two Straight Mode zones at the United States Grand Prix, matching the allocation used in Japan, the Netherlands, Madrid and Baku this season. Under the 2026 technical regulations, active aerodynamics let drivers flatten their front and rear wing angles to shed drag — but only inside designated zones. The first zone runs 120 metres after Turn 20 and ends 60 metres further down the pit straight; the second begins 110 metres after Turn 11 and closes 70 metres later. Overtake Mode detection sits 30 metres after Turn 20, with activation 120 metres past the corner. The decision, announced on Thursday, sets the tactical board for round 18 (October 23–25), a weekend with the championship on a knife edge. Kimi Antonelli arrives with a 102-point lead and could theoretically seal the title in Austin, though Red Bull's Max Verstappen — winner of the last two grands prix, including Singapore — has the paddock buzzing about a late surge. Ferrari and McLaren have also shown Mercedes-beating pace at times this year, so the Texas race looks wide open regardless of the championship maths.
