Technical reference guide
FIA · 2027 · Issue 3How to read definitions, geometry and component tables.
Definitions and geometry
The appendices define technical terms and the reference volumes used to check the car. Car mass includes tyres, driver and driver ballast, but excludes fuel. CAD construction geometry is not automatically a legality boundary; the specified final volumes and surfaces matter.
Drawings and supply boundaries
The drawings clarify measurement conventions, component locations and safety indicators. Supply and sealed-component boundaries are separate columns in the power-unit tables. A component included in one boundary is not automatically included in another. Upgrade permissions remain subject to their stated conditions.
Component classification
The classification table identifies component categories, system boundaries, included items and exclusions. Read the complete row with the corresponding article; a familiar component name alone does not establish whether a team may obtain or share its design. This guide condenses the appendices rather than reproducing their engineering tables.
