Here’s the latest on the FIA banning Mercedes and Red Bull trick in F1.
What happened: The FIA banned a qualifying engine trick used by Mercedes and Red Bull after concerns over safety and fairness. Both teams relied on a regulatory loophole to push electrical/engine power deployment longer into the lap, gaining a performance edge in tight qualifying runs. The governing body ruled that the technique breached the spirit of the regulations and introduced a ban to close the loophole. This has effectively neutralized the previously used tactic for future sessions.[4][8][9]
Timeline and impact: The ban was announced in mid-April 2026, ahead of the Miami Grand Prix, with teams advised that the specific continuous-offset/emergency-deployment approach is no longer permitted except in genuine emergency conditions. The consequence is an expected loss of a few tenths per lap for Mercedes and Red Bull, narrowing gaps on the grid and redistributing likely pole contenders. Racing analysts cite a potential around 0.4–0.5 seconds per lap reduction in the affected areas, depending on track characteristics.[5][8][4]
Reactions and next steps: Mercedes and Red Bull publicly acknowledged the ruling and paused or adjusted their systems accordingly, while rivals welcomed the move as restoring competitive balance. The decision prompted discussions about mid-season rule clarifications and how quickly governing bodies can close loopholes without stifling innovation. Teams are now focusing on alternative performance avenues within the existing regulations for the rest of the season.[10][4][5]
Illustration: A quick mental model—imagine a runner who learns to tap into a pit-stop booster in the final straight. Once the race organizers close that booster, the runner must finish with standard pacing again, leveling the field rather than rewarding the one who cheated the engine’s ramp timing. In F1 terms, the ban removes the late-lap edge the two teams briefly exploited.
