Sources: 2. Developments: 2. Formula 1 drivers have voiced significant concerns regarding technical and powertrain regulations. Max Verstappen initially defended his criticisms of current engine regulations, specifically targeting the heavy reliance on electrical energy. He suggested that some commentators misunderstood the technical complexities and flaws within the system, a sentiment echoed by engineer Mario Illien, who warned that excessive electrical emphasis could increase costs and diminish the sport's spectacle. Following the Mexico City Grand Prix, the criticism expanded to include the 2026 powertrain regulations. Lewis Hamilton and Lando Norris expressed frustration with provisions allowing the FIA to limit electrical power output at high speeds, a phenomenon referred to as clipping. Hamilton described these settings as the worst in the sport's history, arguing that speed limits at the end of straights prevent overtaking and negate the slipstream effect. Verstappen added that this clipping effect specifically reduces overtaking opportunities into Turn 1. ## Timeline ### 2026-11-04: Lewis Hamilton criticizes F1 2026 engine regulations Lewis Hamilton and Lando Norris have criticized the 2026 Formula 1 engine regulations, claiming power output limits at high speeds prevent overtaking and diminish racing quality. 2 sources. https://clstr.news/cluster/lewis-hamilton-criticizes-f1-2026-engine-regulations ### 2026-10-18: Max Verstappen defends criticism of Formula 1 engine regulations Max Verstappen has defended his criticism of Formula 1's hybrid power unit regulations, arguing that the heavy reliance on electrical energy impacts racing and that some critics misunderstand the technicalities 2 sources. https://clstr.news/cluster/max-verstappen-defends-criticism-of-formula-1-engine-regulations --- Cite as: Formula 1 driver criticism of engine regulations.
