The trick that has now been banned by the FIA was first spotted by rivals during the Australian Grand Prix. It allowed Mercedes and Red Bull to gain a significant advantage during qualifying laps, providing a speed boost of 50kW to 100kW over competitors in the final sector. This advantage was achieved by circumventing mandatory power reduction requirements, enabling drivers to maintain maximum deployment longer than allowed.
Concerns regarding the safety implications of this trick surfaced during the Japanese Grand Prix when drivers experienced power losses. Ferrari was among the teams that raised alarms about these safety issues with the FIA. In response, the FIA clarified that MGU-K shutdowns must only be utilized for legitimate emergencies, not as a means to enhance performance.
The FIA has now clamped down on that practice, implementing a ban on the trick ahead of the Miami Grand Prix. This decision was reinforced by the introduction of a ‘continuous offset’ mode to deter the use of MGU-K shutdowns for performance enhancement. Under the new regulations, 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 loophole during cooldown laps after qualifying efforts without facing penalties. However, the FIA’s updated technical directives now make it clear that such practices are not permissible.
As the motorsport community digests this significant change, observers are keen to see how it will impact the performance of these teams in upcoming races. The FIA’s decisive action reflects its commitment to ensuring fair competition and prioritizing driver safety in Formula 1.
