FIA Confirms Two Straight Mode Zones for F1 United States Grand Prix

Active Aero Deployment at the Circuit of the Americas

Formula 1 drivers will use active aerodynamics for the first time at the 20-corner Circuit of the Americas this weekend, with the FIA confirming two Straight Mode zones for the United States Grand Prix. Round 18 of the 2026 championship takes place in Austin, Texas, where teams face a fresh technical challenge under current regulations. PlanetF1 reported that the technical rules introduced this season allow drivers to adjust front and rear wing angles. This system reduces drag on straights and optimizes downforce in corners when deployed in designated zones determined by the FIA.

The number of Straight Mode zones shifts significantly from circuit to circuit. The season-opening Australian Grand Prix featured five zones, while Monaco utilized zero due to its tight street layout. The United States Grand Prix matches the two-zone allocation seen previously in Japan, the Netherlands, and Baku. The first zone at COTA begins 120 metres after Turn 20 and runs for 60 metres down the pit straight. The second zone starts 110 metres after Turn 11 and extends for 70 metres. Meanwhile, Overtake Mode detection sits 30 metres after Turn 20, with activation occurring 120 metres past the same corner.

Tyre Demands and Asphalt Wear at COTA

Pirelli’s weekend preview highlights that the 5.513-kilometre Austin circuit combines high-speed corners, rapid direction changes, and slower sections demanding strong traction. Teams selected the C2 compound as the hard tyre, the C3 as the medium, and the C4 as the soft for the event. The first sector places intense stress on front tyres through fast corners, while third-sector acceleration zones generate thermal degradation primarily on the rear axle. A section between Turns 9 and 11 underwent resurfacing earlier this year, but ageing effects across the rest of the track contribute to high overall wear levels.

High ambient temperatures typically characterize the Texan weekend, potentially increasing degradation and pushing teams toward alternative strategies. While the C2 hard compound offers a solid option for potential long stints, teams must balance straight-line speed with efficient aerodynamic load through technical sections.

Championship Battle and Recent Form in North America

Formula 1 arrives in North America to kick off a final triple-header that includes Mexico City and Sao Paulo, leaving six rounds remaining in the 2026 campaign. TSN noted that Mercedes teammate Kimi Antonelli holds a 102-point lead over George Russell in the drivers’ championship heading into the weekend. Max Verstappen secured victory at the Singapore Grand Prix, marking his second grand prix win of the season following a strong run of form for Red Bull.

McLaren attempts to halt a downward trajectory in Austin after slipping from Mercedes’ nearest challenger to the fourth-best squad in recent months. Motorsport.com reported that Lewis Hamilton holds the record for six wins around COTA, while Verstappen has won the U.S. Grand Prix four times.
