Everything you need to know about the new F1 2026 engine rules
Formula 1 has revamped its power unit rules for 2026, following 12 seasons of stability. The primary adjustment is the increased emphasis on electric power, with the new units aiming for a 50/50 balance between electric and internal combustion engine output. Although practically, the internal combustion engine is set to still provide the bulk of the power during a lap. The 2026 F1 power units consist of a 1.6-liter turbocharged engine incorporating various components like the turbocharger, battery, control electronics, and the motor-generator unit. The electric power is generated by the MGU-K, anticipated to deliver 350kW, a significant jump from the previous generation. The complex MGU-H from the former era has been eliminated in favor of an enhanced MGU-K setup for 2026.
Furthermore, new terms like ‘overtake mode’ have been introduced in context with electrical power management. ‘Recharge’ is now the official term for storing additional energy in the battery, with various methods available for drivers to replenish it. Additionally, sustainable fuels will be a key feature in 2026, with teams required to use advanced sustainable components meeting strict emission standards. Fuel sustainability will be checked by the FIA in partnership with specialist third-party organizations and provided by fuel suppliers like Shell, Petronas, Aramco, Castrol, and ExxonMobil.
