Severe Vibrations Force Alonso's Early Exit at Chinese Grand Prix
Fernando Alonso's Chinese Grand Prix weekend came to a premature end due to persistent vibration problems stemming from Honda's power unit. The excessive vibrations left the driver unable to maintain proper control of his vehicle, ultimately leading to his retirement from the race.

Fernando Alonso's Chinese Grand Prix campaign ended in frustration as Honda's vibration issues proved too severe to overcome during the event. The relentless vibrations plaguing the car caused significant physical strain on the driver, with Alonso reporting that the intensity was so extreme he "struggled to feel my hands" during his time on track.
The technical problems originated from Honda's power unit, which generated excessive vibrations that compromised both the driver's comfort and vehicle performance. Unable to continue operating the car under such difficult conditions, Alonso was forced to bring his machine into the pits and retire from the race.
This mechanical setback highlighted the ongoing challenges Honda has faced in addressing reliability and vibration-related concerns on its power units this season. The severity of the issue underscores the critical nature of resolving these technical problems for the team moving forward.

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 C17.1.7
Safety and Reliability Claims
Chapter: C17
In Simple Terms
F1 teams are responsible for making sure their cars are safe and reliable. This rule means a team can't blame other parties (like rival teams, suppliers, or the FIA) for safety or reliability problems that are actually their own responsibility.
- Teams must take responsibility for their car's safety and reliability
- Teams cannot make claims against other parties for issues they are responsible for
- This prevents teams from unfairly blaming competitors or external parties for their own mechanical failures
- Promotes accountability and fair competition among F1 teams
Official FIA Text
F1 Team responsible for safety and reliability issues shall not make claims against other parties inconsistent with that responsibility.
Article B8.2.1
Power Unit Conformity
Chapter: B8
In Simple Terms
Teams can only use power units (engines) in races if every part of that engine was approved by FIA officials when it was first introduced. This means all components must match what the team originally submitted and had checked off as legal.
- Only approved power units are allowed in races
- Every component must conform to the latest homologation dossier
- Parts must have been approved at the time they entered the race pool
- Teams cannot modify or substitute unapproved engine components
Official FIA Text
The only Power Unit that may be used at a Competition during the Championship is a Power Unit which is constituted only of elements that were in conformity, at the date they were introduced in the Race pool, with the latest submitted and approved homologation dossier.
