Full Regulation Text
Article C5.2.7
ERS-K Absolute Electrical Power
Chapter: C5
In Simple Terms
The ERS-K (kinetic energy recovery system) is the hybrid power unit that harvests energy from braking. F1 regulations cap the maximum electrical power this system can produce at 350kW to maintain competitive balance and prevent any team from gaining an unfair advantage through excessive hybrid power.
- ERS-K electrical power output is strictly limited to a maximum of 350kW
- This applies to the absolute DC electrical power measurement of the kinetic energy recovery system
- The limit ensures all teams operate within equal technical parameters for the hybrid system
- Exceeding this power threshold would constitute a technical regulation breach
Official FIA Text
Absolute electrical DC power of ERS-K may not exceed 350kW.
Article C5.2.10
ERS-K Harvesting Limits
Chapter: C5
In Simple Terms
F1 cars can harvest a maximum of 8.5 megajoules of energy per lap from their braking system (ERS-K). The FIA can reduce this limit to 8MJ or 5MJ if needed, and teams can harvest an extra 0.5MJ under certain special conditions.
- Standard ERS-K harvesting limit is 8.5MJ per lap
- FIA can reduce the limit to 8MJ or 5MJ based on their determination
- Up to 0.5MJ additional energy can be harvested under specified conditions
- This energy comes from the car's braking system during each lap
Official FIA Text
Energy harvested by ERS-K must not exceed 8.5MJ in each lap. May be reduced to 8MJ or 5MJ depending on FIA determination. Up to 0.5MJ additional energy may be harvested per lap under specified conditions.
Article C5.2.11
MGU-K Mechanical Torque
Chapter: C5
In Simple Terms
The MGU-K (Motor Generator Unit - Kinetic) can only push a maximum of 500 Newton-meters of mechanical torque back to the engine. This limit ensures the hybrid system doesn't give cars an unfair power advantage and keeps the technology balanced across the grid.
- MGU-K mechanical torque is capped at 500Nm to prevent excessive hybrid power assistance
- The limit is measured relative to crankshaft speed, ensuring consistent regulation across different engine operating conditions
- This rule maintains competitive balance by preventing teams from exploiting the hybrid system for unlimited performance gains
Official FIA Text
MGU-K mechanical torque magnitude may not exceed 500Nm referenced to crankshaft speed.
