According to reports, Formula 1’s active aerodynamics for the 2026 regulations are currently undergoing changes due to troubling findings in simulations. The upcoming changes to the power unit regulations, which were finalized in 2022, aimed to achieve a 50/50 power split between internal combustion and electrical components in hybrid engines. This shift towards sustainability was intended to attract new engine manufacturers, including Audi. However, the increased electrification in the new power units has raised concerns about energy recovery and conservation. The FIA hoped that active aero would address these concerns, but simulations have revealed significant issues with the initial plan of a movable rear wing. As a result, the rule-makers are reevaluating their approach.
Initially, the plan was for the rear wing to have a high downforce configuration in corners and then switch to a low-drag setup on the straights, along with the use of DRS. However, when teams tested these configurations in simulators, they discovered a severe change in aerodynamic balance when transitioning from corners to straights. This change was found to be three times more extreme than the effect of DRS, putting drivers at risk of spinning out when accelerating on the straights. In response to these findings, the FIA has decided to include moveable front and rear wings in the design.
The new plan is based on the theory that shifting the aero balance at both the front and rear of the car will make the transition more manageable for the drivers, reducing the risks involved. By implementing this change, the FIA hopes to find a solution that maintains the desired performance and safety standards for Formula 1.
The aerodynamic rules for 2026 are scheduled to be formulated by the conclusion of June this year. It will not be permissible for teams to commence work on the 2026 chassis and bodywork until the commencement of next year, allowing a 12-month timeframe for preparation. Additionally, the CFD and wind tunnel assessments on the 2026 cars will be integrated into the cost-cap regulations for 2025. Pierre Wache, the Technical Director of Red Bull, has already expressed his apprehensions regarding the upcoming technical regulations. In an interview with Autosport, he conveyed his concern that the FIA did not thoroughly consider the complete concept of these new regulations simultaneously. He further stated that the engine regulations were initially defined, and now they have to address the issue on the chassis side to compensate for it. Christian Horner, the Team Principal, also shared his thoughts with the publication, expressing that there has been progress and the FIA has taken some feedback into account, resulting in certain modifications. He emphasized the significance of concluding the chassis regulations, as they will be a crucial component of the 2026 package and their interaction with the power units. Various working groups are diligently working on this matter, and it is imperative that a resolution is reached in the near future.
