Alonso Opts Out: Physical Toll Forces Early Exit in China
Fernando Alonso made the decision to withdraw from the Chinese Grand Prix after experiencing numbness in his extremities caused by excessive engine vibrations. The discomfort left the driver feeling there was insufficient reason to continue competing in the race.

Engine vibrations proved too much for Fernando Alonso to overcome during the Chinese Grand Prix, as the persistent physical effects forced him to call time on his race early. The Aston Martin driver found himself battling numbness spreading through his hands and feet—a direct result of the mechanical disturbances emanating from his power unit throughout the event.
Faced with mounting discomfort and seeing no viable path to a meaningful result, Alonso made the pragmatic choice to bring his car to a halt rather than soldier on through the remainder of the grand prix. The combination of the physical toll and lack of competitive opportunity left little incentive for the two-time world champion to continue his Sunday.
It was a frustrating conclusion to the weekend for Alonso, who ultimately found the race conditions untenable as the technical issues continued to plague his driving experience in Shanghai.

- Turbocharger maximum speed is capped at 150,000 rpm
- Rule ensures engine reliability and prevents excessive power gains
- Violation can result in engine component failure or competitive advantage
- Teams use electronic limiters to monitor and control turbo speed

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.
