C5.2.10 The energy harvested by the ERS-K Recharge, as measured at the CU-K HV DC Bus, must not exceed a limit of 8.5MJ in each lap, subject to the following additional conditions: i. This limit may be reduced to 8MJ at Competitions where the FIA determines that the maximum possible energy harvested per lap attributable under braking and in partial load is no more than 8MJ. ii. This limit may be further reduced to no less than 5MJ for Sprint Qualifying and Qualifying sessions at Competitions where the FIA determines that the harvesting strategies required to achieve the above limit are excessive, subject to the conditions specified in Article B7.2. iii. Up to 0.5MJ of additional energy may be harvested in each lap subject to the conditions specified in Article B7.2. The vehicle fundamentals used to determine the above limits will be provided in the document FIA- F1-DOC-034. 2026 Formula 1: Technical Regulations 27 February 2026 C6 5 C 0 SECTION C: TECHNICAL REGULATIONS C5.2.11 The MGU-K mechanical torque magnitude may not exceed 500Nm.

C5.2.8 Additionally, and subject to Article B7.2.1, the electrical DC power of the ERS-K used to propel the car may not exceed: i. When Overtake is not active: P(kW) = 1800 – 5 * car speed (kph) when the car speed is below 340kph P(kW) = 6900 – 20 * car speed (kph) when the car speed is equal to or above 340kph and below 345kph P(kW) = 0 when the car speed is equal to or above 345kph ii. When Overtake is active In Override Mode up to: P(kW) = 7100 – 20 * car speed (kph) when the car speed is below 355kph P(kW) = 0 when the car speed is equal to or above 355kph. C5.2.9 The di_erence between the maximum and the minimum state of charge of the ES may not exceed

C5.12.4 Except for conforming to Article C5.2.8, the driver maximum power demand cannot be reduced by more than 150kW at the start of any power limited pending period, and the power reduction will remain fixed for a minimum of 1s. Further exceptions are permitted for specified circuit sectors, subject to Article B7.2.1. C5.12.5 The driver maximum power demand cannot be increased during any power limited pending or

C5.12.5 The driver maximum power demand cannot be increased during any power limited pending or power limited period, except when the overtake mode Boost is selected by the driver, or, subject to Article B7.2.1, when a reset of any power reduction is permitted. C5.12.6 Unless the electrical DC power of the ERS-K is negative, and subject to Article B7.2.1, the driver

C5.2.8 Additionally, and subject to Article B7.2.1, the electrical DC power of the ERS-K used to propel the car may not exceed: i. When Overtake is not active: P(kW) = 1800 – 5 * car speed (kph) when the car speed is below 340kph P(kW) = 6900 – 20 * car speed (kph) when the car speed is equal to or above 340kph and below 345kph P(kW) = 0 when the car speed is equal to or above 345kph ii. When Overtake is active In Override Mode up to: P(kW) = 7100 – 20 * car speed (kph) when the car speed is below 355kph P(kW) = 0 when the car speed is equal to or above 355kph. C5.2.9 The di_erence between the maximum and the minimum state of charge of the ES may not exceed

C5.12.7 The electrical DC power of the ERS-K may not be reduced at rates greater than those specified in Article C5.12.6, unless: • the theoretical MGU-K power resulting from reduction at rates equal to those specified in Article C5.12.6 is negative; • the ICE power is negative and the ERS-K power needs to be reduced further to achieve the driver demand; • the ERS-K power needs to be reduced further to achieve the maximum power permitted by Article C5. 2.8; • the driver power demand is negative; • a gearshift is in progress. • car speed is below 210kph.
