Aston Martin's Bahrain test hampered by Honda parts shortage

Aston Martin's final day of pre-season testing in Bahrain was severely disrupted as a battery issue and a shortage of Honda power unit parts forced the team to abandon its run plan. Lance Stroll failed to complete a single lap in the opening two hours of Friday's session, capping a troubled first test for the new Adrian Newey-designed AMR26 car.

Why it matters:

The pre-season test is a critical period for teams to gather data, build reliability, and fine-tune their new cars. For Aston Martin, starting a new era with a landmark Newey chassis and Honda power, these repeated stoppages represent a significant setback. Limited mileage means less understanding of the car's potential and less time to solve problems before the competitive season begins, putting the team on the back foot from the very start.

The details:

• The team's issues stemmed from a battery-related problem that first appeared during Fernando Alonso's running on Thursday, curtailing his afternoon session.
• Honda Racing Corporation (HRC) confirmed the problem impacted their test plan and stated that, combined with a shortage of power unit parts, they had to adapt to a "very limited" run plan consisting only of short stints on Friday.
• The AMR26 has completed fewer than 400 laps across the three-day test, with neither Alonso nor Stroll enjoying a trouble-free day in the car.
• Despite the visible struggles, Fernando Alonso remained publicly optimistic earlier in the week, stating, "I think everything can be fixed" and that there is "a solution in place" for the team's problems.

What's next:

Aston Martin faces a race against time to diagnose the root cause of the battery issue and secure the necessary spare parts from Honda before the season-opening Australian Grand Prix. The team's immediate focus will be on maximizing the limited time between the test and the first race to implement fixes. Alonso's stated goal of fixing "everything that we can before Australia" will now be put to the test, with the team's early-season performance and reliability hanging in the balance.
