Overview
- An FIA spokesperson says the session was pre-planned and will cover 2026 power unit and chassis topics, with the compression interpretation on the agenda.
- Reports indicate Mercedes and, to a lesser extent, Red Bull can satisfy the static ambient test yet achieve a higher effective ratio at operating temperatures.
- Article C5.4.3 defines the check as a static, ambient procedure approved in each manufacturer’s homologation dossier, creating tension with the broader compliance clause.
- Audi, Ferrari and Honda have formally sought clarification after the FIA initially appeared comfortable with Mercedes’ interpretation, with major rewrites viewed as unlikely before mid-season or 2027.
- The Additional Development and Upgrade Opportunities system offers disadvantaged suppliers extra ICE upgrades based on power assessments in blocks of six races.
