This rule ensures fair competition by preventing teams from using an unrestricted battery range.
- Energy storage can fluctuate by a maximum of 4MJ between its highest and lowest charge states during racing
- This limitation applies whenever the car is on track, including practice sessions and races
- The rule prevents teams from gaining unfair advantages through unrestricted battery management strategies
- Teams must carefully calibrate their energy recovery and deployment systems to stay within this window
