La Formule 1 prévoit des ajustements des unités de puissance pour la saison 2027

Les parties prenantes de la Formule 1 ont convenu en principe de rééquilibrer la puissance des unités motrices à partir de l'année prochaine. Ces changements visent à répondre aux préoccupations concernant les systèmes hybrides actuels introduits en 2026. Les responsables envisagent également une transition à plus long terme vers des moteurs plus simples.

La FIA, les écuries, les motoristes et la direction de la Formule 1 ont décidé d'augmenter la puissance du moteur V6 de 50 kW pour atteindre 450 kW, tout en réduisant le déploiement du moteur électrique du même montant à 300 kW. Cet ajustement sera rendu possible par des limites de débit de carburant plus élevées et devrait permettre de maintenir des niveaux de charge de batterie plus élevés pendant les tours, tout en réduisant les différences de vitesse lors du phénomène de « super clipping ». Les discussions se poursuivent sur l'augmentation de la limite de récupération du moteur électrique au-delà de 350 kW et sur l'accroissement de la capacité de la batterie de 4 MJ à 5 MJ.

McLaren team principal Andrea Stella has revealed that Formula 1 teams and the FIA are in talks about potential hardware tweaks to the 2026 power units. These could include larger battery capacity or increased fuel flow to improve driving dynamics. Recent regulation adjustments ahead of the Miami Grand Prix aim to address some issues, but more substantial changes may take time.

Formula 1 CEO Stefano Domenicali has called for stakeholders to agree on the next generation of power unit regulations as early as this year. He emphasized the need to act quickly due to long lead times, while respecting investments from manufacturers like Audi and Honda. Domenicali backs lighter, simpler engines centered on sustainable fuel and strong internal combustion.

Formula 1's new power units for 2026 are making race starts more difficult, as highlighted during the Bahrain pre-season test. Without the MGU-H component, engines must rev higher and longer to optimize turbo performance, prompting teams to seek regulatory changes. Drivers warn that botched starts could cost multiple positions on the grid.

Formula 1 CEO Stefano Domenicali expressed confidence that the series will adjust its new 2026 technical regulations to address concerns from drivers and fans. He highlighted increased overtaking and growing global interest despite issues in qualifying sessions. Stakeholders are meeting to implement short-term changes ahead of the Miami Grand Prix.
