The FIA has banned a qualifying trick used by Mercedes and Red Bull that allowed for significant speed boosts at the end of laps. This decision follows concerns raised during the Japanese Grand Prix regarding safety implications of the trick, which involved circumventing mandatory power reduction requirements.
The trick enabled drivers from both teams to maintain maximum deployment of their MGU-K for longer than allowed, providing an advantage of 50kW to 100kW over competitors during the final sector of qualifying laps. Observers noted that all four drivers from these teams could run at maximum deployment as they approached the finish line.
This practice was first spotted by rivals during the Australian Grand Prix, leading to scrutiny from the FIA. Safety concerns were highlighted when drivers experienced power losses during the Japanese Grand Prix, prompting Ferrari to raise alarms about the implications of the trick.
In response, the FIA clarified that MGU-K shutdowns must only be utilized for legitimate emergencies, not for systematic performance enhancement. They have now issued updated technical directives to enforce this ban ahead of the Miami Grand Prix.
The FIA has introduced a ‘continuous offset’ mode to deter the use of the MGU-K shutdown trick. If the MGU-K is shut down, it cannot be activated again for 60 seconds, which could be detrimental during races.
Mercedes and Red Bull had realized they could exploit this trick during cooldown laps after qualifying efforts without facing penalties. However, the FIA’s latest measures aim to eliminate such loopholes.
The ban on this qualifying trick reflects the FIA’s commitment to ensuring fair competition and safety in Formula 1. The governing body has updated technical documents to enforce the new regulations effectively.
As the Miami Grand Prix approaches, teams will need to adapt to these changes. The FIA has now clamped down on this practice, emphasizing the importance of safety and compliance with regulations in the sport.
