Aston Martin's testing woes continue with Alonso stoppage

Aston Martin's troubled pre-season hit another snag on Thursday when Fernando Alonso was forced to stop his car on track in Bahrain due to a dramatic engine issue, compounding the team's lack of running ahead of the new Formula 1 season.

Why it matters:

Reliability is the foundation of any testing program, and these repeated stoppages severely limit the team's ability to gather crucial data and develop the car. With the season opener just days away, Aston Martin is running out of time to solve its problems and risks starting 2026 on the back foot against rivals who have enjoyed smoother preparations.

The details:

• The incident occurred during the second day of the final pre-season test in Bahrain. Fernando Alonso, who took over from Lance Stroll, had completed 68 laps before the problem arose.
• The car initially slowed after Turn 3 with an apparent issue before a major spike in engine revs at Turn 4 forced Alonso to stop the AMR26 completely.
• The session was red-flagged as mechanics recovered the car, and Alonso walked back to the pits.
• This follows a disrupted first day of the test, where Lance Stroll spun into the gravel, further eating into the team's track time.
• Aston Martin's pre-season challenges began earlier, with the team missing the first three days of a shakedown test in Barcelona, putting them on the back foot from the very start of their 2026 program.

What's next:

The team faces a race against time to diagnose and fix the latest issue before the final day of testing. Every lost lap represents lost data and development opportunity. If these reliability gremlins persist into the first race weekend, Aston Martin could find itself playing catch-up in the competitive midfield from the very first lap of the new season, a costly position for a team with ambitions of moving further up the grid.
