With F1 teams’ development focus mostly on the 2026 cars, late-season upgrades have taken an unusual path
Formula 1 teams have shifted their focus to the significant rules revolution for 2026, resulting in a less aggressive in-season upgrade battle during the 2025 campaign.
Most major developments were planned early in the year to avoid diverting resources from the new cars, with exceptions like unique Monza low downforce wings and rear suspension layout revisions by Ferrari at the Belgian Grand Prix.
While some teams like Red Bull continued with floor developments, the trend is towards cost-effective upgrades that exploit areas needing minimal time and resources for substantial gains.
Sauber’s sporting director highlighted the different upgrade approach this year, with a focus on simple tweaks and potential gains, particularly in areas like brake ducts.
Teams, including Sauber and Alpine, are utilizing computer simulations for cost-effective modifications to existing components in their pursuit of performance gains while preparing for the 2026 regulations.
