Alonso: Aston Martin gains modest
Fernando Alonso has revealed that recent improvements to Aston Martin's driveability represent only incremental progress, with the AMR26 continuing to struggle significantly against its competitors. The team and Honda remain committed to identifying and resolving the fundamental issues affecting the car's performance, though a substantial performance gap persists in qualifying trim.

Incremental Progress Falls Short of Target
Fernando Alonso's assessment of Aston Martin's recent technical developments paints a sobering picture of the team's struggles with the AMR26. The Spanish driver indicated that driveability enhancements achieved thus far translate to approximately "half a tenth" of lap time—a modest gain that underscores the magnitude of the challenge facing the Silverstone-based outfit and its Japanese engine supplier Honda.
The revelation comes as the partnership continues its methodical approach to diagnosing and rectifying the multifaceted issues that have plagued the car since its initial introduction to competition. Despite these ongoing efforts, the AMR26 remains positioned at least two seconds adrift of the pace in qualifying conditions, a deficit that highlights the depth of work still required to bring the package up to competitive standards.
Systematic Problem-Solving Approach
Aston Martin and Honda have publicly reaffirmed their commitment to what they characterize as a drilling-down process into the root causes affecting the AMR26's performance envelope. This methodical approach reflects the complexity of the issues at hand, which extend beyond simple aerodynamic or setup adjustments.
One of the earliest obstacles encountered by the team involved reliability concerns. These issues created a significant impediment to the developmental work necessary to understand the car's fundamental characteristics and behavior. The reliability problems created a bottleneck effect, delaying the accumulation of track data and restricting opportunities to test potential solutions in race and practice conditions.
Powertrain Complexities
The technical difficulties extend into the powertrain architecture itself, with multiple problematic elements requiring attention. Vibrations transmitted through the chassis represent one notable concern among the various issues affecting the drivetrain's integration with the rest of the car. These vibrations, stemming from the engine and transmission systems, have proven difficult to isolate and eliminate, requiring careful diagnostic work to identify their origin points.
The involvement of Honda as the engine partner means that solutions often require close collaboration between the engine manufacturer and Aston Martin's chassis engineers. This coordination is essential given that many powertrain-related issues manifest as handling problems or chassis vibrations that can mask their true source. Understanding whether an issue originates from the power unit itself or from how that unit interfaces with the car's structure demands expertise from both organizations working in concert.
Performance Gap Analysis
The two-second deficit in qualifying trim represents a substantial performance shortfall that cannot be attributed to a single factor. Rather, the cumulative effect of multiple issues—some reliability-related, others pertaining to driveability and powertrain integration—has created a situation where the car lacks the overall efficiency and consistency required to match the performance of leading competitors.
Qualifying performance serves as a critical benchmark in Formula 1, as it determines grid positions and provides a clear, objective measure of a car's peak performance capability. The scale of the gap evident during qualifying sessions suggests that fundamental work remains necessary across several areas of the car's design and operation, rather than simple refinements being sufficient to close the margin.
Looking Forward
Alonso's candid assessment regarding the limited scope of recent improvements demonstrates a realistic perspective on the work ahead. Rather than overstate the significance of marginal gains, the driver's acknowledgment that recent progress amounts to only "half a tenth" reflects an understanding that the journey back to competitiveness will require sustained effort and likely more substantial technical breakthroughs than have thus far materialized.
The continued partnership between Aston Martin and Honda underscores both organizations' commitment to resolving these issues systematically. The complexity involved—spanning reliability, powertrain integration, vibration management, and overall driveability—demands sustained focus and comprehensive problem-solving approaches that extend across multiple technical domains.

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.

Chapter: C5
In Simple Terms
The ERS-K (kinetic energy recovery system) is the hybrid power unit that harvests energy from braking. F1 regulations cap the maximum electrical power this system can produce at 350kW to maintain competitive balance and prevent any team from gaining an unfair advantage through excessive hybrid power.
- ERS-K electrical power output is strictly limited to a maximum of 350kW
- This applies to the absolute DC electrical power measurement of the kinetic energy recovery system
- The limit ensures all teams operate within equal technical parameters for the hybrid system
- Exceeding this power threshold would constitute a technical regulation breach
Official FIA Text
Absolute electrical DC power of ERS-K may not exceed 350kW.
