Active aero and the plank wear problem
In 2026, Formula 1 cars will be equipped with fully active aerodynamics. The wings will switch between two positions: more downforce in corners and less drag on the straights. Drivers will switch manually in special activation zones designated by the FIA.
The rules allow for the straight-line stabiliser to be switched off in unsafe conditions. This applies, for example, when there is heavy rain. With too little downforce on wet road surfaces, a car can become unstable and dangerous.
Unexpected risk: plank wear
Teams discovered an unintended problem. When cars with high downforce drive on straights, the forces press the car harder onto the road surface. This increases the risk of wear or damage to the wooden plank (skid block). Plank wear results in penalty points and even disqualification. This was recently demonstrated by the double disqualification of a team.
The combination of higher fuel and energy costs due to drag is already a point of concern. However, wear and tear on the wing is a much bigger problem. Teams and the FIA discussed the subject at length in technical and sporting committees.
How the FIA intends to resolve the issue
FIFA officials (FIA) and teams are working on practical adjustments. One solution that is now taking shape is to shorten activation zones in unsafe conditions, such as rain.
In dry conditions, an activation zone can be the entire length of a straight. When it rains, that zone becomes much shorter or disappears altogether. Less time in the straight means that the car is subjected to the greatest vertical forces for a shorter period of time. This reduces the risk of the plank buckling.
- Shorter activation zones in wet conditions.
- Ability to completely eliminate upright position in dangerous situations.
- Option to switch only the front wing element in the rain, to reduce the pressure on the front section.
Practical and ongoing consultation
The FIA has indicated that several options have been discussed. The details are still being finalised before the rules are officially adopted. Teams and technical management want a solution that is both safe and technically feasible.
The issue has become even more urgent because there have already been several cases of excessive paddle wear this season. In addition to the most recent disqualification, there were earlier incidents involving other teams during the Chinese and Bahrain Grand Prix respectively.
Ultimately, the sport seeks to strike a balance between safety, fair competition and technical innovation. The proposed shorter activation zones should make this possible without undermining the core of the new 2026 rules.
