The Fédération Internationale de l’Automobile (FIA) has officially approved several new amendments to the technical regulations for the 2026 Formula 1 season, including notable changes to hybrid energy recovery systems, floor wear tolerance, and minimum ride height.
Despite the fact that all ten teams on the current Formula 1 grid have already been working for months on designing and simulating their next-generation race cars, the FIA continues to refine and update the framework that will govern the new era of Formula 1 beginning in 2026. During the most recent meeting of the World Motor Sport Council, the governing body ratified multiple updates to the aerodynamic regulations and to how teams are allowed to use brake ducts to control tyre temperatures. These adjustments are now joined by additional key revisions regarding floor wear, ground clearance specifications, and the rules governing hybrid power unit recharge strategies.
Changes to Ride Height Parameters
One of the most impactful updates concerns the static ride height measurement that is taken under parc fermé conditions at the end of a race. While the minimum ground clearance at the rear of the car remains unchanged at 30 millimetres, the minimum height at the front of the car will increase from the current 10 millimetres to 15 millimetres in 2026. This modification is expected to significantly influence the ongoing development of the 2026 cars, forcing teams to revisit their vehicle concepts and rework both aerodynamic baselines and suspension systems in order to comply with the new chassis dynamics.
These newly established values confirm that the next generation of Formula 1 machinery will operate at a higher ride height compared to the current 2025 cars. Interestingly, even with this greater clearance from the ground, the FIA has opted to double the permitted floor plank wear. At present, the resin-based plank mounted underneath the car is allowed to wear down by only 1 millimetre during the course of a Grand Prix. However, beginning in 2026, this tolerance will increase to 2 millimetres, potentially impacting car setup strategies and downforce management. In contrast, the diameter of the wear measurement holes will be reduced from 50 millimetres to 34 millimetres, introducing a tighter control in assessing compliance.
Hybrid Power Usage to Be Limited in Qualifying Sessions
Further updates also affect the hybrid portion of the Formula 1 power unit, particularly with regard to energy recovery and deployment limits. According to the new regulations, the MGU-K (Motor Generator Unit – Kinetic) will be allowed to harvest a maximum of 8.5 megajoules (MJ) of energy per lap under normal conditions. However, if the layout of a specific circuit prevents effective regeneration—due to a lack of heavy braking zones—the limit will be reduced to 8 MJ.
More importantly, if a track is classified as particularly fast and features few opportunities for regenerative braking, the FIA will further reduce the hybrid recharge allowance during qualifying sessions (including Sprint Qualifying formats) to just 5 MJ per lap. This is a significant change in approach aimed at preserving the purity of flat-out laps during qualifying, where driver skill and maximum combustion engine power are expected to shine.
The core objective behind this move is to prevent drivers from being forced to lift off the throttle on straights in order to recharge the battery during single-lap runs—an action which could compromise the spectacle and defeat the purpose of pushing the cars to their absolute limit. The FIA thus intends to prioritize the use of the internal combustion engine in qualifying, ensuring that hybrid energy deployment does not influence pure performance over one flying lap.
In essence, the regulatory body seeks to maintain the tradition of thrilling qualifying sessions, where every millisecond counts, while also laying the groundwork for a more sustainable and performance-balanced future in Formula 1.
