Overview

• The FIA will monitor each engine’s average ICE output over the opening five race weekends and grant extra development money, dyno hours and re-homologation rights to any manufacturer more than 3 percent down.
• Regulators say the 2026 power-unit formula is simpler—with a 50/50 electrical-thermal split, removal of the MGU-H and active-aero overtaking modes—to lower the risk of runaway performance gaps.
• Single-seater director Nikolas Tombazis cautioned that some teams remain secretive with simulator and power-unit data, giving the FIA levers to intervene if transparency falls short.
• Williams has publicly accepted its FW47 will struggle in high-load corners through 2025 as it channels resources into a targeted chassis redesign for the 2026 rules package.
• Driver adaptation remains under scrutiny, with Lewis Hamilton battling rear instability at Ferrari and George Russell stressing patience as Mercedes refines its next-generation car.
