McLaren welcomes F1 2026 power unit rule changes
Formula 1 stakeholders have refined the controversial 2026 power unit regulations, with McLaren emerging as a vocal proponent of the adjustments. The changes, set to be implemented ahead of the upcoming Miami Grand Prix, specifically target the elimination of the counter-intuitive "lift and coast" driving style that was anticipated to plague qualifying sessions.
The previous iteration of the 2026 power unit rules, which mandate a near 50-50 split between combustion and electric energy, presented significant challenges. Drivers found themselves unable to employ their natural driving style in qualifying, with energy-starved cars forcing them into an unusual strategy.
To achieve an optimum lap time, competitors would have to lift off the throttle early on straights and coast through fast corners, primarily to charge the battery. This approach not only compromised qualifying performance but also raised safety concerns due to elevated closing speeds between cars.
The core issue stemmed from drivers being penalised for pushing harder through corners, as it would prematurely deplete their power unit's energy on subsequent straights. The refined regulations aim to rectify this by increasing the super clip limit from 250 to 350kW and reducing the harvesting limit from eight to seven MJ.

These adjustments are designed to significantly reduce the necessity for drivers to "lift and coast" into corners.
Mark Temple, McLaren's technical director for performance, highlighted the positive impact on the driver experience. "The biggest impact is from a driving point of view," Temple told Motorsport.com. "The idea is to get rid of some of these things that the drivers don't like doing in qualifying - the idea of the car coasting for a long period of time into the high-speed chicane rather than a more natural feeling of staying on full throttle and then braking harder."
Temple further elaborated on how the changes will enable a more conventional approach to racing. "There are two parts to it. One of them is what we call lift and coast, which should no longer be a thing in qualifying, which is where the driver actually lifted off the throttle and then coasted into the braking zone and then hit the brakes," he explained. "We've now got a situation where it's more efficient and that's controlled by the power unit, so the driver can stay at full throttle and the power unit will recover the energy, straight mode will stay active, so the car slows down less."
While the immediate changes are welcomed, McLaren team boss Andrea Stella suggested that further refinements might be necessary in the long term. "I think the changes that are implemented for Miami are a positive step in the right direction," Stella commented. "There's already something in the pipeline to further improve what's been put in place for Miami. I think Formula 1 as a community should remain quite open, that once we observe the outcome and the effect of this package of changes, we may have learned more about the new regulation and further tuning may be required."

The FIA, F1's governing body, is also trialling a "low power start detection system" as part of the ongoing evolution of the 2026 regulations. This proactive approach underscores the sport's commitment to ensuring competitive and safe racing as it transitions to the new power unit era.
