F1 trials energy rules, new start safety
- The FIA said on April 20 that Formula 1 will change its 2026 energy-management rules from the Miami Grand Prix, while trialing a new automatic start-safety system for slow-launching cars. - The package cuts maximum recharge from 8 megajoules to 7, raises peak “superclip” power to 350 kilowatts from 250, and adds flashing warning lights when the start system intervenes. - The tweaks follow data from the first three 2026 races in Australia, China and Japan, after teams and drivers pushed to reduce lift-and-coast running.

Formula 1 will arrive in Miami with new 2026 energy rules and a trial start-safety system after the Fédération Internationale de l’Automobile approved a mid-season package on April 20. (fia.com) (formula1.com) The biggest immediate change is in qualifying and race energy use. The FIA cut maximum permitted recharge from 8 megajoules to 7 and raised peak “superclip” power to 350 kilowatts from 250. (fia.com) (formula1.com) In plain terms, recharge is the electricity a car harvests under braking and stores for later. The FIA said the lower cap should reduce time spent harvesting and keep drivers closer to flat-out pace, with maximum superclip use cut to about two to four seconds per lap. (fia.com) (formula1.com) The race package also changes how electric boost is delivered. The FIA capped extra boost at 150 kilowatts in race trim and kept MGU-K deployment at 350 kilowatts only in key acceleration zones, with 250 kilowatts elsewhere on the lap. (fia.com) (formula1.com) That matters because the first three races under the new rules exposed a tradeoff: cars could become too dependent on harvesting energy, especially in qualifying, instead of pushing continuously. The FIA said the Miami changes were based on data from Australia, China and Japan plus input from drivers, teams and power-unit manufacturers. (fia.com) (formula1.com) (motorsport.com) The start-system trial targets a different problem: a car that leaves the grid abnormally slowly can become a hazard before the field reaches Turn 1. The FIA said its new “low power start detection” system will spot weak acceleration just after clutch release and automatically deploy MGU-K power to restore a minimum launch. (fia.com) (formula1.com) Cars affected by that intervention will also flash rear and side lights to warn drivers behind them. The FIA said the system will be tested in Miami first and only adopted permanently after feedback and analysis. (fia.com) (formula1.com) The governing body also widened its flexibility for low-energy events. The number of races where alternative lower energy limits may apply rose from eight to 12, giving Formula 1 more room to tailor the rules to different circuit layouts. (fia.com) (formula1.com) The changes were agreed in an online meeting that included the FIA, team principals, chief executives of power-unit manufacturers and Formula One Management. Miami, scheduled for May 1-3, is the first race weekend where the revised energy rules will apply. (fia.com) (formula1.com) So the Miami weekend is now a live test of two fixes at once: less harvesting during laps, and less risk if a car bogs down off the line. The FIA will use the results there to decide whether the start system becomes a permanent part of the 2026 rule set. (fia.com) (motorsport.com)
