Drivers at the Miami Grand Prix said the tweaks tested there did not eliminate battery-influenced superclipping, excessive closing speeds or problematic overtaking, and they called for further technical fixes. Lando Norris urged the sport to “get rid of the battery,” saying the measures were only a small step in the right direction. All three podium finishers, Kimi Antonelli, Lando Norris and Oscar Piastri, delivered a blunt assessment that the changes were incremental rather than a complete solution and said the situation “isn’t at the level Formula 1 should still be at yet.”

McLaren’s Oscar Piastri described the wheel-to-wheel racing in Miami as “random,” saying frequent position changes with Mercedes’ George Russell were driven by differing energy-harvesting and deployment patterns and by variable availability of Overtake Mode. Piastri cited Russell closing from roughly one second to make a straight-line overtake as an example of the large closing speeds that make defending extremely difficult. He said he had been unhappy with one of Russell’s moves but later acknowledged he had executed a similar maneuver himself. Piastri praised cooperation between the FIA and F1 on the tweaks and said the reduced harvest limit in qualifying has helped a bit, but he warned current hardware limits mean more substantive fixes would require complex technical work and questioned how quickly such changes could be implemented.

Norris said the tweaks had not yet produced the flat-out qualifying laps the sport needs and complained that drivers remain penalized when trying to go flat-out. The Miami changes included a reduction in recoverable energy in qualifying, kept at eight megajoules for Miami and Suzuka, and an increase in the on-throttle energy recovery rate intended to discourage battery-recharge tactics and reduce lift-and-coast.

Antonelli, the Miami winner who extended his early championship lead with a third consecutive victory, agreed qualifying felt better but warned that closing speeds, active aero and battery characteristics still pose major race concerns. Drivers and teams remain skeptical that the tweaks fully address overtaking and wheel-to-wheel stability and called for further power-unit and deployment fixes after the opening three rounds prompted the adjustments.
