Severe Vibration Issues Force Aston Martin to Restrict Driver Stint Lengths in 2026 Campaign
Aston Martin is grappling with dangerous vibration levels from its Honda power unit that are compelling the team to cap driver running at just 25 laps per session to prevent potential hand and nerve injuries. Team principal Adrian Newey has disclosed the extent of the problem, which emerged during the challenging pre-season testing phase marked by multiple reliability concerns.

Aston Martin faces a significant technical challenge as it navigates the early stages of its partnership with Honda, with vibration problems from the power unit proving so pronounced that they're restricting how long drivers can safely spend behind the wheel.
The severity of the vibration issue has reached a point where team leadership must implement protective measures to safeguard driver health. According to Aston Martin team boss Adrian Newey, the oscillations are intense enough to risk causing nerve damage to the hands if drivers remain in the car beyond approximately 25 laps during any given session.
The collaboration between Aston Martin and Honda has encountered considerable difficulties from its inception. The pre-season testing program revealed a troubling pattern of reliability setbacks that substantially limited the running time available for the AMR26. Beyond the mechanical failures that plagued early development, the vibration characteristics of the power unit have emerged as a particularly concerning issue requiring immediate attention.
This constraint on driver exposure time represents a substantial obstacle as the team works to develop and optimize the 2026 season car. With testing opportunities already compromised by reliability problems, the additional limitation on lap count further restricts the data gathering and development work that Aston Martin can accomplish during crucial preparation phases.

Article 2.2
2026 Power Unit Regulations
Chapter: Chapter II - Power Unit Changes
In Simple Terms
2026 brings major engine rule changes. The complex MGU-H is removed to cut costs and attract new manufacturers. To compensate, the MGU-K becomes much more powerful and the battery is bigger. The goal is simpler, more sustainable power units that are still cutting-edge.
- MGU-H removed from power units
- MGU-K power increased significantly
- Larger energy store capacity
- Aims to attract new manufacturers
Official FIA Text
For 2026, the power unit will comprise a 1.6 litre V6 turbocharged internal combustion engine with a significantly enhanced electrical component. The MGU-H will be removed. The electrical power output will increase substantially with a more powerful MGU-K and larger energy store.
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 B11.2.7
TCC Opportunities
Chapter: B
In Simple Terms
Teams are limited to specific testing opportunities throughout the year: one private 5-day test and two public 3-day tests before the season starts, plus a 1-day test after the season ends. They can also do tire testing (up to 40 car days) and one 1-day substitute driver test. These rules prevent teams from gaining unfair advantages through excessive testing.
- Pre-season testing limited to one 5-day private test and two 3-day public tests
- Post-season testing restricted to one 1-day test only
- Out-of-competition tire testing capped at 40 car days maximum
- One additional 1-day test allowed for substitute drivers
Official FIA Text
TCC limited to pre-season private collective testing (one 5-day test), pre-season public collective testing (two 3-day tests), post-season test (one 1-day test), out-of-competition tyre testing (maximum 40 car days), and substitute driver test (one 1-day test).
