Chapter: C12
In Simple Terms
The upper part of the energy recovery system (ERS) battery cannot be positioned too far forward in the car. Specifically, any portion of the battery that extends above a certain height must stay behind a defined forward limit line. This rule ensures cars maintain proper weight distribution and safety standards.
- The restriction applies only to parts of the ERS battery above a specific height threshold (Z=51)
- The battery's forward position is limited by the fuel tank's forward boundary line
- This regulation affects car design and packaging in the rear of the vehicle
- The rule maintains consistent technical standards across all competitors
Official FIA Text
