Honda Power Unit Woes Leave Aston Martin in Critical Supply Situation Ahead of Melbourne
Aston Martin faces a precarious reliability crisis as the team grapples with a severe shortage of functioning batteries for its newly integrated Honda power unit. With only two operational units remaining, the British outfit finds itself in an increasingly difficult position ahead of the Melbourne Grand Prix.

The partnership between Aston Martin and Honda has already hit turbulent waters, with the Silverstone-based team confronting a worrying shortage of working batteries for the Japanese manufacturer's latest F1 engine specification.
Team officials have revealed that Aston Martin's reserves have dwindled to just two serviceable batteries, leaving the squad operating in what they candidly describe as a "scary place" when it comes to power unit dependability. This concerning shortage threatens to complicate preparations for the upcoming Melbourne round.
The battery supply crisis represents one of the early challenges facing this new partnership between Aston Martin and Honda as they embark on their collaborative journey in Formula 1. With such limited backup options available, the team faces mounting pressure to ensure maximum reliability throughout the forthcoming races, as any component failures could prove deeply problematic given the current stock levels.
This reliability headache adds another layer of complexity to what promises to be a demanding start to the season for Aston Martin as they integrate Honda's power unit into their operational framework.

Article 5.1
Definition of a New PU Manufacturer
Chapter: SECTION C: TECHNICAL REGULATIONS
In Simple Terms
A 'New PU Manufacturer' is a company entering F1 for the first time that hasn't built power units before (2014-2021) and hasn't inherited significant technology from existing manufacturers. If approved by the FIA, they receive special benefits and exemptions for 5 years (from 3 years before entry through 1 year after). The FIA evaluates applicants based on their facilities, engine experience, and ERS system knowledge.
- New PU Manufacturers must meet two conditions: no prior homologation since 2014 AND no significant inherited IP from established manufacturers
- Approved new manufacturers receive a 5-year window of special rights/exemptions (N-3 to N+1 calendar years)
- The FIA has absolute discretion in granting status and evaluates applicants on infrastructure investment, ICE experience, and ERS system expertise
Official FIA Text
A PU Manufacturer intending to supply PUs for the first time in year N, will be considered to be a "New PU Manufacturer" if it (or any related party): a. has not homologated a PU at least once in the period 2014-2021; and b. has not received any significant recent Intellectual Property from a PU Manufacturer who is not a New PU Manufacturer, subject to the conditions outlined in Article 5.2 of this Appendix. (together, for this Article 5 only, the "Necessary Conditions") The "New PU Manufacturer" status will be granted by the FIA, at its absolute discretion, for the complete calendar years from N-3 to N+1. In order to be granted the "New PU Manufacturer" status, the PU Manufacturer in question must, upon the request of the FIA, provide the FIA with all of the detailed information or documents requested by the FIA describing the commercial background and details of the PU Manufacturer's business, the Intellectual Property owned by the PU Manufacturer and the technical relationship between the PU Manufacturer and any other related entity or persons (the "Requested Documentation"). PU Manufacturers granted a "New PU Manufacturer" status are given additional rights or exemptions in certain provisions of the Technical, Sporting and Financial Regulations. In order to assess whether the Necessary Conditions have been satisfied by a PU Manufacturer, the FIA will assess the Requested Documentation provided by the PU Manufacturer with regard to three factors: a. Infrastructure: the necessity for the PU Manufacturer to build facilities, invest significantly in assets, and hire personnel with prior Formula 1 experience; b. ICE status: the prior experience of the PU Manufacturer in Formula 1 Internal Combustion Engines, and potential possession of significant recent Intellectual Property; and c. ERS status: the prior experience of the PU Manufacturer in Formula 1 ERS systems, and potential possession of significant recent Intellectual Property.
Article B8.2.2
Power Unit Element Limitations
Chapter: B8
In Simple Terms
Each driver has a limited allocation of power unit parts they can use across a season. The most restrictive components are the engine, turbocharger, and exhaust (3 each), while some parts like the energy store and control electronics are limited to 2, and smaller ancillary components to 5. Once a driver exceeds these limits, they face grid penalties.
- Engines, turbochargers, and exhausts are limited to 3 per driver per season
- Energy storage units (ES) and control electronics (PU-CE) have tighter restrictions at 2 per season
- MGU-K units are also limited to 2 per driver
- Ancillary power unit components have the most generous allowance at 5 per season
Official FIA Text
Each driver may use no more than: 3 engines (ICE), 3 turbochargers (TC), 3 exhaust sets (EXH), 2 energy store units (ES), 2 control electronics units (PU-CE), 2 MGU-K, and 5 of each Power Unit ancillary component (PU-ANC).
Article C5.19.1
FIA Approved Energy Store Cells
Chapter: C5
In Simple Terms
F1 teams can only use energy storage cells (batteries) that have been officially approved by the FIA. Manufacturers must submit their cell designs for approval by November 1st of the year before they plan to use them, ensuring all teams use safe and regulated components.
- Only FIA-approved cells can be used in the energy storage system
- Power Unit manufacturers must submit approval requests to the FIA Technical Department
- Approval deadline is November 1st of the preceding year
- This regulation ensures standardization and safety across all F1 teams
Official FIA Text
Only cells approved by the FIA Technical Department may be used in the ES. The approval request form must be sent by the PU Manufacturer to the FIA before the 1st of November of the preceding year.
