Honda 'not happy' with performance and reliability after Aston Martin testing setback

Aston Martin and Honda's final pre-season test in Bahrain was severely hampered by a battery issue and a shortage of power unit spare parts, limiting Lance Stroll to just six laps on the final day. Honda's chief engineer admitted the manufacturer is "not happy" with both performance and reliability, casting a shadow over their new works partnership just two weeks before the season opener in Australia.

Why it matters:

This rocky start tests the foundation of the highly anticipated works partnership between Aston Martin and Honda from its very first season. Persistent reliability issues and a lack of spare parts so close to the first race could derail their development program and leave them on the back foot competitively, undermining their goal of challenging the established frontrunners.

The details:

• The problems began on Thursday when a battery issue curtailed Fernando Alonso's running after 68 laps.
• The issue spilled over to Friday, compounded by a critical shortage of spare parts for the power unit, forcing the team to implement a severely limited run plan.
• Lance Stroll managed only six installation laps on the final day without setting a timed lap, bringing Aston Martin's total for the six days of Bahrain testing to under 400 laps—a significantly low mileage compared to rivals.
• Shintaro Orihara, Honda's trackside general manager, confirmed the team failed to achieve its mileage target for the test.
• Despite the troubles, Orihara emphasized a unified effort between Honda's base in Sakura, Aston Martin's factory in Silverstone, and the crew in Bahrain to diagnose and find solutions.

What's next:

The clock is ticking for the new partners to find fixes before the Australian Grand Prix. The collaborative effort mentioned by Honda will be under immense pressure to improve both reliability and performance in a very short timeframe.

• Any lingering issues in Melbourne would put the team at an immediate strategic disadvantage for the opening rounds.
• The situation highlights the intense challenge of a new manufacturer-team alliance in a cost-cap era, where spare part logistics and rapid problem-solving are as critical as pure performance.
