Article 3.11
Minimal incidental changes due to modifications to other PU components
Chapter: APPENDIX C5: HOMOLOGATION AND DEVELOPMENT OF POWER UNITS, FUEL AND OIL FOR 2026-2030
In Simple Terms
Teams can make small, necessary changes to one power unit part if they've modified a different part on a different upgrade schedule. These minor tweaks need official approval before implementation. Think of it as allowing knock-on adjustments when upgrading components.
- Small unplanned changes to PU components are allowed if they result from upgrades to other components
- The different components must be on different upgrade schedules to qualify
- All modifications require approval through the official process in Article 3.10.a
- These are truly 'incidental' changes only—not major redesigns
Official FIA Text
Minimal incidental changes may be carried out on PU components as a consequence of changes made to another PU component with a different upgrade schedule. Such modifications are subject to the approval process outlined in Article 3.10.a of this Appendix.
