What Does PU-ANC Mean in F1?

PU-ANC stands for Power Unit Ancillary Components. It is an FIA term used for a group of supporting components connected to a F1 car's power unit.

Unlike major power unit elements such as the internal combustion engine (ICE), turbocharger (TC) or MGU-K, PU-ANC covers a range of smaller systems and components required for the power unit to operate correctly.

The FIA Technical Regulations identify exactly which components are classed as PU-ANC. Examples include parts of the intake system, high-pressure fuel system, fuel injectors, wastegate and pop-off valve systems, the main power unit oil tank, breather systems, ERS cooling components and parts of the hydraulic control system.
