F1 Australia GP 2026: all official updates and major wing developments
The FIA has released the technical and summary documents detailing all updates brought by Formula 1 teams to Melbourne for the opening round of the 2026 season.
The first 11 FIA technical sheets for Melbourne reveal a clear common theme: the 2026 regulations have shifted teams’ focus from purely chasing downforce to rebuilding the aerodynamic balance of the car. The most visible change compared to 2025 is that front and rear wings are now central to development, as they must perform efficiently in both Corner Mode and Straight Mode, managing a more delicate trade-off between downforce and drag.
A second recurring trend is also evident: simpler floors, less reliance on extreme solutions seen in the previous generation, and more work on flow quality. Many updates involve the floor edge, diffuser, sidepods, engine cover, and rear corners — all areas now aimed at feeding the rear of the car more effectively and stabilizing aerodynamic behavior.
The main difference from pre-season designs is this: while launch designs showed primarily base architectures, Melbourne already features targeted corrections to make 2026 cars more efficient, stable, and better adapted to the new active-aerodynamics logic.
McLaren
McLaren arrives in Melbourne with a package focused primarily on the rear of the car. The main work targets the floor, which has been redesigned to improve airflow around the rear tires and increase downforce generated by both the floor and rear corners.
The Woking team has also updated the rear suspension fairing, aiming to direct airflow more cleanly toward the rear impact structure and diffuser. This update is designed to improve the quality of airflow at the car’s rear, enhancing stability and overall aerodynamic performance.
The final update concerns the rear wing, which features a new mainplane and flap configuration aimed at increasing local downforce while maintaining efficiency.
| Component | Purpose | Change | Description |
