The recharge limit works: reduced superclipping, and Montreal helped
Energy recovery management has quickly become one of the first major technical talking points of the 2026 Formula 1 season. Not because hybrid systems are anything new to Formula 1, but because the new balance between electric power, aerodynamic drag, and active systems has made a phenomenon far more visible than in previous years: clipping, and especially superclipping.
The issue became impossible to ignore after Suzuka. The clearest example came on the stretch after Spoon Curve, where drivers exited under full acceleration and kept the throttle pinned all the way toward 130R, only to run out of available electrical energy before reaching the corner. At that point, the car did not simply stop gaining performance. Instead, it effectively began to coast, arriving at the chicane with speed dictated more by energy management than outright pace. In qualifying, where a lap should represent the purest form of attack, the sensation was almost paradoxical: cars flat-out on the throttle, yet already being held back by the system.
The numbers from the opening races illustrate the trend clearly. In Melbourne, George Russell accumulated 4.72 seconds of superclipping across 12 separate events, along with an additional 1.96 seconds of lift-and-coast. In Shanghai, that figure climbed dramatically to 9.60 seconds over 11 events. At Suzuka, the circuit that truly brought the issue into focus, Kimi Antonelli recorded 5.32 seconds across 8 events. Then came Miami, where the phenomenon surged again, with 9.92 seconds of superclipping across 17 separate interventions. At that stage, this was no longer a minor technical footnote, but a structural part of a qualifying lap.
That is what prompted the FIA to intervene with revised ERS recovery limits for qualifying. The intention was not to remove electrical energy management from the equation, because in Formula 1’s 2026 regulations, hybrid deployment remains central to performance. The real objective was to stop teams from chasing battery energy in unnatural ways, creating situations where drivers experienced deceleration despite keeping the throttle fully open, or were forced into awkward lift phases purely to recharge the battery. Put simply, the goal was to make qualifying less of an energy accounting exercise and more of a genuine limit-pushing challenge.
The Canadian Grand Prix provided the first genuinely meaningful test. In Montreal, the maximum recovery limit was set at 6 MJ per lap, significantly lower than circuits such as Monaco, Hungary, and Singapore, where the cap rises to 9 MJ. It was also below medium-range tracks like Miami, Spa-Francorchamps, Barcelona, Austin, and Qatar, which sit at 8 MJ. The reasoning is straightforward: a single fixed number cannot work everywhere. The limit must reflect the circuit’s energy profile.
The Canadian results should be viewed through exactly that lens. Clipping and superclipping did not disappear in Montreal. George Russell still recorded 6.00 seconds of full-throttle deceleration across 8 events. However, compared to Miami, the improvement is striking. In Florida, the equivalent figure was 9.92 seconds across 17 events. In Canada, total clipping and superclipping time dropped by around 40%, while the number of interventions was cut by more than half. Electrical energy management still shaped the lap, but it became less fragmented, less artificial, and less dominated by constant system-imposed micro-decelerations.
The explanation lies in the relationship between recoverable braking energy and the FIA’s imposed ceiling. Miami and Montreal showed remarkably similar braking characteristics in the analysed data. Miami featured a braking percentage of 16.86%, while Canada came in at 16.74%. The braking severity index was also identical, rated at 2 for both circuits. That means the difference was not really about the amount or intensity of braking opportunities, but about how closely the energy naturally recoverable under braking aligned with the FIA’s maximum recovery limit.
In Miami, the car could recover approximately 4.8 MJ net through braking. But with a higher permitted limit, teams still needed to find a substantial amount of additional energy outside those natural recovery zones. In Montreal, by contrast, the 4.3 MJ net recoverable under braking sat much closer to the 6 MJ cap. That left only 1.7 MJ to make up elsewhere. This is the technical heart of the issue: not the absolute number of heavy braking zones, but how close a circuit allows teams to get to the ERS ceiling without resorting to artificial strategies such as partial throttle, lift phases, or excessive superclipping.
That is why qualifying in Canada felt easier to interpret. Not because the problem vanished, but because it returned to a more acceptable scale. Six seconds of superclipping remains significant, especially over a single qualifying lap. But it is fundamentally different from nearly ten seconds spread across seventeen interventions. In the first case, energy management influences the lap. In the second, it starts to define the lap more than the driver does.
There is, however, an important caveat: Montreal itself helped. Circuit Gilles Villeneuve is built around heavy braking zones, sharp acceleration phases, and long high-speed sections. It naturally offers strong energy recovery opportunities under braking, but at the same time, it could have exaggerated the issue had the recovery cap remained too high. That makes it an ideal circuit for testing whether the FIA’s calibration works, but also one that naturally favours better outcomes. With braking severity comparable to Miami, cooler temperatures, and virtually no thermal penalty, the system enjoyed more favourable conditions for energy recovery without distorting the lap too aggressively.
That is why the conclusion cannot simply be that 6 MJ is the perfect number. That would be far too simplistic. What Canada actually demonstrates is something more nuanced: the limit must be tailored to the circuit. Where the track naturally allows substantial energy recovery, the ceiling can remain higher. Where the gap between available energy and the permitted maximum becomes too large, lowering the cap becomes necessary to prevent excessive clipping and superclipping.
In that sense, Montreal offers a credible direction for Formula 1. The FIA does not need to strip hybrid complexity out of qualifying, nor should Formula 1’s 2026 rules turn battery deployment into a marginal factor. But it does need to ensure that a qualifying lap is not distorted by a constant need to recharge. Canada showed that when the maximum recovery limit is brought closer to the energy a circuit can realistically generate, superclipping decreases, and qualifying returns closer to its intended nature: a balance between car, driver, and strategy, without strategy becoming the only story.
The successful deployment of custom ERS recovery limits in Montreal therefore marks a significant victory for the ongoing refinement of the 2026 technical regulations. By adapting the energy ceilings to match the specific stop-and-go telemetry of the Canadian circuit, the FIA has demonstrated that it can preserve the core integrity of a qualifying lap without neutering the sophisticated hybrid power units. As the championship moves toward venues with vastly different energy demands, maintaining this tailored, circuit-specific approach to energy caps will be vital. If the governing body can replicate this operational balance across high-speed, low-braking layouts later in the season, Formula 1 will successfully navigate its power-delivery growing pains, ensuring that driver bravado and raw mechanical engineering remain the defining metrics of single-lap performance.
