Article 3.7
Minor modifications to Power Unit components
Chapter: APPENDIX C5: HOMOLOGATION AND DEVELOPMENT OF POWER UNITS, FUEL AND OIL FOR 2026-2030
In Simple Terms
Teams can make small changes to their power unit parts, like switching suppliers or updating branding, without needing a completely new design. These tweaks don't significantly affect how the engine performs and just need FIA approval to be allowed.
- Minor modifications include cosmetic changes like different branding or supplier switches
- Changes must have little to no impact on reliability or engine performance
- All modifications require approval through the official FIA process (Article 3.10.a)
- This rule allows practical updates without triggering major technical restrictions
Official FIA Text
Minor modifications may be made to Power Unit components subject to the approval process outlined in Article 3.10.a of this Appendix. Such modifications may be (but are not limited to) due to different branding, a change of supplier, a change of part number, etc. and may have no or very limited effect on reliability or functionality.
