Mercedes-Powered Teams Voice Frustration Over Technical Documentation Gaps
Customer teams running Mercedes power units have expressed discontent regarding incomplete technical materials for the AMG F1 W17 EQ Performance. The teams appear to be missing critical sections of the instruction manual needed for optimal setup and operation of their vehicles.
Friction has emerged among the satellite operations utilizing Mercedes engines, with multiple teams reporting dissatisfaction over what they characterize as incomplete technical support documentation. The issue centers on the AMG F1 W17 EQ Performance manual, where customer teams claim several pages of essential information have been omitted from their copies.
The missing documentation has prompted concerns about competitive parity and operational efficiency, as teams suggest they lack crucial guidance that could impact their performance throughout the season. This shortfall in technical materials has become a notable point of tension between Mercedes and its customer operations, highlighting potential communication gaps in the transfer of vehicle specifications and operational procedures.
The situation underscores broader questions about the level of support and resources allocated to customer teams compared to the factory Mercedes operation, a dynamic that continues to shape the competitive landscape in Formula 1.

Article 2
Information provided by the PU Manufacturer to their customer F1 Teams
Chapter: APPENDIX C5: HOMOLOGATION AND DEVELOPMENT OF POWER UNITS, FUEL AND OIL FOR 2026-2030
In Simple Terms
Engine manufacturers must give F1 teams detailed plans and specifications of their power units in two stages: a preliminary version by August and a final version by November of the year before competition. If anything significant changes after August, the manufacturer must notify teams immediately, and if teams think the changes are unfair, they can ask the FIA to investigate within 7 days.
- Engine manufacturers must provide preliminary technical specifications and 3D models to teams by August 1st of the year before competition
- Final detailed specifications, operating parameters, and installation procedures must be submitted by November 1st
- Any significant changes after August 1st require immediate notification to customer teams and FIA approval
- Customer teams have 7 days to challenge unreasonable changes, with the FIA deciding within 14 days whether modifications are acceptable
Official FIA Text
Any PU Manufacturer intending to supply a Power Unit to an F1 Team during a Championship (year N) must: a. Declare to the FIA, before 1 August of year N-1, that they provided to their customer F1 Teams: i. An initial full external space model of the Power Unit including details and locations of all physical interfaces required by the team to install the Power Unit. ii. Preliminary estimates of important operating parameters such as heat rejection, fuel mass and density, clutch shaft stiffness and engine stiffness. b. Declare to the FIA, before 1 November of year N-1, that they provided to their customer F1 Teams: i. A final full external space model of the Power Unit including details and locations of all physical interfaces required by the team to install the Power Unit. ii. Firm predictions of important operating parameters such as heat rejection, fuel mass and density, clutch shaft stiffness and engine stiffness. iii. Initial details of any other parts, procedures, operating conditions and limits or any other information required by the team to install and operate the Power Unit as intended. After the 1 August of year N-1, any significant change compared to previous communication, must be notified to the customer F1 Teams in due time. Should a Customer Team consider that the change has an unreasonable impact on the Power Unit installation in the car, they may contact the FIA within 7 days of the notification. The FIA will then contact the relevant PU Manufacturer and its customer F1 Teams in order to conduct its investigation. If the FIA is satisfied, in its absolute discretion, that these changes are acceptable, the FIA will confirm to the PU Manufacturer and the customer F1 Teams within 14 days that they may be carried out.
Article 1.2
Homologation dossier contents
Chapter: Appendix C5
In Simple Terms
Before a team can use a new power unit in F1, they need to submit a complete package of paperwork to the FIA. This package must list every major power unit component, all the smaller parts, and other required documents following a specific FIA template (FIA-F1-DOC-C047). Think of it as getting your engine approved before you can race.
- Teams must document all Power Unit (PU) Elements - the major components like the engine, turbo, and MGU systems
- A detailed list of Minor Parts must be included - smaller components that make up the power unit
- All submissions must follow the official FIA-F1-DOC-C047 format and template
- This homologation process is the approval system that ensures all power units meet F1 regulations
Official FIA Text
Dossier must include details of all PU Elements, detailed list of Minor Parts, all required documents, submitted per FIA-F1-DOC-C047.
Article C17.4.2
TRC/FSC Supply Provisions
Chapter: C17
In Simple Terms
This rule explains how teams that supply parts to customer teams must do so fairly. If a supplier team doesn't give a customer team certain components, they have to follow the same rules as regular teams, except for one special exception. Teams that aren't in a supplier-customer relationship must follow standard equipment rules.
- Supplier teams must provide TRC (Transferable Race Components) or FSC (Freely Supplied Components) to customer teams on fair terms
- If components aren't supplied to a customer team, the supplier team follows standard LTC (Limited Transfer Components) rules with one exception
- Teams without a supplier-customer relationship must follow standard LTC equipment regulations
- Article C17.4.5 provides a specific exception to standard rules for certain supply situations
Official FIA Text
Provisions regard supply of TRC or FSC to Customer Team. If component not supplied to Customer Team, rules identical to LTC except Article C17.4.5 applies. Teams not in Supplying-Customer relationship must observe LTC rules.
