Power unit homologation and development
FIA · 2027 · Issue 3An approved dossier controls specifications and permitted upgrades.
An approved reference specification
A manufacturer submits a homologation dossier covering its power unit and updates it when approved changes are introduced. A sealed reference unit supports conformity checks. The dossier applies to every supplied team, with narrowly defined exceptions for fuel, oil or installation changes. Customer teams receive installation information and equivalent operating capability under the specified supply requirements.
Controlled development
Upgrades follow the component schedule; reliability, safety, cost or supply changes require the applicable approval process. Additional Development and Upgrade Opportunities depend on the FIA’s engine-performance assessment and the eligibility rules. They are not unlimited development rights. The appendix also governs availability to customer teams, deadlines, unused allowances and proof that race units match their approved dossier.
