Aston Martin's Vibration Woes Force Alonso to Abandon Chinese GP Bid
Fernando Alonso encountered severe physical discomfort during his Aston Martin campaign at the Chinese Grand Prix, with numbness affecting his extremities as the car battled dangerous vibrations. The reliability issues ultimately forced the veteran driver to retire, highlighting ongoing concerns the team and Honda are addressing with their powertrain.
Fernando Alonso has revealed that he experienced alarming sensations of numbness in both his hands and feet during portions of the Chinese Grand Prix, a concerning development that preceded his eventual retirement from the race in his Aston Martin.
The Spanish driver's exit from the event came as a result of excessive vibrations plaguing his vehicle throughout the afternoon, contributing to a frustrating conclusion to what had been a challenging race weekend.
Aston Martin and its engine supplier Honda have been making concerted efforts to mitigate the effects of these vibration problems, which have proven problematic for vehicle reliability and battery performance alike. The technical partnership continues to work toward solutions as they navigate the challenges presented by the current generation of power units.

Full Regulation Text
Article C5.2.9
Energy Storage State of Charge Range
Chapter: C5
In Simple Terms
The energy storage system (ES) in F1 cars must maintain a relatively narrow operating window while racing. The difference between when the battery is most charged and least charged cannot exceed 4 megajoules at any point the car is on track. This rule ensures fair competition by preventing teams from using an unrestricted battery range.
- Energy storage can fluctuate by a maximum of 4MJ between its highest and lowest charge states during racing
- This limitation applies whenever the car is on track, including practice sessions and races
- The rule prevents teams from gaining unfair advantages through unrestricted battery management strategies
- Teams must carefully calibrate their energy recovery and deployment systems to stay within this window
Official FIA Text
Difference between maximum and minimum state of charge of ES may not exceed 4MJ at any time car is on track.
Article C5.1.13
Engine Oil Consumption
Chapter: C5
In Simple Terms
F1 engines must be extremely efficient with oil consumption, using no more than 0.30 liters per 100 kilometers during normal racing conditions. This rule ensures teams develop reliable, well-engineered power units while preventing excessive oil burn that would give unfair performance advantages.
- Maximum oil consumption limit is 0.30 liters per 100km
- Applies during normal operating conditions only
- Promotes engine reliability and efficient engineering
- Prevents teams from using oil burn as a performance advantage
Official FIA Text
Engine oil consumption must never exceed 0.30l/100km in normal operating conditions.
Article 5
Conformity with the power unit homologation dossier
Chapter: APPENDIX C5: HOMOLOGATION AND DEVELOPMENT OF POWER UNITS, FUEL AND OIL FOR 2026-2030
In Simple Terms
F1 engines must be built in a way that allows the FIA to put official seals on them for inspection. The engine manufacturer and teams using that engine must prove to the FIA at any time that their engine matches the original approved design specification.
- Power units must be designed to allow FIA seals to be fitted for verification purposes
- Both engine manufacturers and teams must cooperate fully with FIA technical inspections
- Teams must demonstrate engine conformity with the homologation dossier whenever the FIA requests it
- The FIA has absolute discretion to demand compliance checks at any competition
Official FIA Text
All Power Units must be delivered such that the seals required under Article B8.2.9 can be fitted. Both the Power Unit Manufacturer and users of a homologated Power Unit must take whatever steps are required at any time by the FIA Technical Department, in its absolute discretion, to demonstrate that a Power Unit used at a Competition is in conformity with the corresponding Power Unit homologation dossier.
