Alonso Frustrated as Aston Martin Grapples with Honda Battery Shortage Ahead of Australian GP
Fernando Alonso has expressed disappointment over Aston Martin's inability to secure spare batteries for its Honda power units as the team battles significant technical challenges in its inaugural campaign with the Japanese manufacturer. The Silverstone-based squad faces an uncertain start to the 2026 season, with excessive engine vibrations threatening to derail its Australian Grand Prix participation.
As Aston Martin prepares for what should be an exciting new chapter in its partnership with Honda, the team instead finds itself grappling with mounting frustration and supply chain complications. Fernando Alonso has made clear his dissatisfaction with the situation, particularly regarding the shortage of spare batteries available for the Honda power unit installations.
The partnership between the Silverstone-based team and Honda represents a works agreement for the current regulatory cycle, yet the early stages have been marked by considerable turbulence. Technical difficulties have emerged prominently during pre-season preparations, with excessive vibrations emanating from the engine proving to be a significant concern that threatens to undermine the team's competitive positioning.
What was intended to be a promising fresh start has instead become a test of resilience, as Aston Martin contends with both the technical complications plaguing its Honda power unit and logistical challenges surrounding component availability. The lack of spare batteries in particular has compounded the team's difficulties during what is already proving to be a trying launch phase for this new era.
The complications have become serious enough to cast doubt over the team's readiness for the first race of the season, with the Australian Grand Prix now uncertain as a potential starting point for Aston Martin's 2026 campaign.

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 C5.19
Energy Store
Chapter: C5
In Simple Terms
F1 teams can only use energy storage cells (batteries) in their power units that have been officially approved by the FIA. The FIA will approve these cells as long as the power unit manufacturer doesn't sign exclusive deals that would prevent other teams from using the same supplier.
- Only FIA-approved cells can be used in the Energy Store (ES)
- Power unit manufacturers cannot sign exclusive supply agreements for these cells
- The approval requirement ensures standardization and fair access across all teams
- This rule promotes competition by preventing one team from having sole access to superior battery technology
Official FIA Text
Only cells approved by the FIA Technical Department may be used in the ES. Subject for provision of the Article C18.2.5, the approval of the FIA Technical Department is conditional upon the PU manufacturer undertaking not to conclude any Exclusivity Agreement for the supply of such parts with the supplier.
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.
