Formula 1 has introduced changes to its 2026 power unit regulations in response to 'yo-yo racing,' a back-and-forth style of battling driven by battery energy management. The tweaks, effective for this weekend's Miami Grand Prix, reduce qualifying energy harvesting and increase super clipping power. Drivers remain divided on whether the new rules improve racing.
The 2026 Formula 1 season features lighter chassis and power units with a near 50:50 split between electrical and combustion energy, leading to 'yo-yo racing.' Drivers manage battery levels by downshifting on straights, lift-and-coasting into corners, or using super clipping at full throttle. This has resulted in more overtakes, such as 120 at the Australian Grand Prix compared to 45 in 2025, but battles often see cars passing and re-passing due to varying energy states, as seen in China and Suzuka. FIA single-seater director Nikolas Tombazis noted that automotive industry pressures toward electrification shaped the rules, drawing manufacturers like Audi and Honda. F1 CEO Stefano Domenicali warned against letting competitors dictate regulations, citing Renault's departure at the end of 2025. Drivers' opinions split sharply. Lando Norris described an unwanted overtake on Lewis Hamilton at Suzuka's 130R: “I didn’t even want to overtake Lewis... This is not racing, this is yo-yoing.” Hamilton countered positively, saying the cars allow close following through high-speed corners like karting. Max Verstappen called the rules “anti-racing” and “Formula E on steroids,” deeming them “fundamentally flawed.” Mercedes teammates Kimi Antonelli and George Russell, leading the championship, have praised the racing. Ahead of the Miami Grand Prix, the FIA reduced qualifying harvesting from eight to seven megajoules and raised super clipping from 250 to 350 kilowatts to minimize lift-and-coast and speed differentials. These changes follow safety concerns, including Oliver Bearman's high-impact crash in Japan after closing rapidly on Franco Colapinto's Alpine due to energy differences.
