Alonso reveals Aston Martin's engine vibrations cause numbness, could impact future

Fernando Alonso has revealed that severe vibrations from Aston Martin's Honda power unit leave his hands and feet "a little bit numb" after just 25 minutes of driving, prompting the team to limit his running. The two-time champion expressed "100 percent faith" in Honda to find a fix but admitted the timeline for a solution could influence his decision on whether to continue in Formula 1 beyond this season.

Why it matters:

This is not merely a performance or reliability issue; it's a significant driver health and safety concern with potential long-term consequences. Team principal Adrian Newey has warned of a risk of permanent nerve damage, forcing the team to artificially cap race simulations and practice running. For Alonso, at 44 years old and contemplating his future, the persistence of this problem adds a major physical and career-planning variable to his season.

The details:

• The issue stems from the Honda power unit in the new AMR26, which also caused reliability problems and limited running during pre-season testing.
• Alonso stated the vibrations are severe enough to be felt throughout the car, damaging components and transmitting directly to the driver's body.
• Driver Limits: Newey indicated Lance Stroll feels he can only manage about 15 laps under the conditions, while Alonso can push to roughly 25 before the numbness sets in.
• Adrenaline vs. Risk: Alonso clarified that the sensation isn't "painful" and adrenaline would allow him to push through if fighting for a win, but the unknown long-term effects over a full season are the real concern. "We don't know the consequences either if you keep driving like that for four months," he said.
• Development Push: Honda is working intensively on solutions, with some countermeasures already implemented on the car for the Australian Grand Prix weekend.

What's next:

The immediate focus is on managing the problem race-by-race, with Aston Martin forced to strategically limit its drivers' track time. The bigger question revolves around Honda's development speed.

• Alonso's faith in Honda is based on their history of overcoming early problems, as seen in their journey from being criticized to winning championships with Red Bull.
• However, he directly linked the resolution timeline to his career decisions: "The thing is probably the time that is required, and it’s not matching with my time in my career."
• If improvements come quickly, it could persuade Alonso to extend his career. A prolonged issue, however, may push the veteran toward retirement, adding a high-stakes human element to Honda's technical challenge.
