Unlike major power unit elements such as the internal combustion engine (ICE), turbocharger (TC) or [MGU-K](https://www.f1-fansite.com/glossary/mgu-k-motor-generator-unit-kinetic/), PU-ANC covers a range of smaller systems and components required for the power unit to operate correctly. ### What are Power Unit Ancillary Components? In simple terms, **ancillary components are the supporting parts around the main F1 power unit**. 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. Not every component attached to the power unit is a PU-ANC. The [FIA](https://www.fia.com/system/files/documents/fia_2026_f1_regulations_-_section_b_sporting_-_iss_08_-_2026-08-05_7.pdf "FIA 2026 F1 Regulations - Section B [Sporting] - Iss 08 - 2026-08-05") specifically marks the components that belong to this category in the PU-ANC column of its Technical Regulations. ### How many PU-ANC components can an F1 driver use? For the **2026 Formula 1 season**, the regulations specify a basic allocation of **five of each PU-ANC component**. However, every driver is permitted one additional unit during the 2026 Championship, effectively giving drivers an allocation of **six** before a grid penalty is triggered. This is why FIA technical delegate reports during the 2026 season generally refer to drivers being allowed six new PU-ANC units. ### What happens if a driver exceeds the PU-ANC limit? PU-ANC is part of Formula 1's restricted power unit component system. If a driver exceeds the permitted allocation, the first additional component of that type results in a **10-place grid penalty**. Further additional components of the same type result in **five-place grid penalties**. The regulations also allow PU-ANC components to be transferred between a driver's sealed power unit elements without automatically causing a penalty. ### PU-ANC meaning in short **PU-ANC = Power Unit Ancillary Components** It is the FIA classification for specified supporting components used around an F1 power unit. **2026 allocation:** 5 + 1 additional unit = 6 **First unit above allocation:** 10-place grid penalty **Further additional units:** 5-place grid penalty Here you can see the [2026 used power element for each driver and grid penalties they served](https://www.f1-fansite.com/2026-formula-1-season/2026-used-formula-1-power-unit-elements/).
