It was no surprise when both Aston Martin’s retired from the Australian GP. Adrian Newey told the media on Thursday that reliability issues and dangerous vibrations made completing a race distance unrealistic.
What was unusual, however, is when both Fernando Alonso and Lance Stroll returned to the track several laps after ‘retiring’. Perhaps understandably, Aston decided to spend their Sunday focusing on data collection – accepting that points were unattainable.
In a minor miracle, Alonso managed to get himself into 10th place on lap 1. This excellent start put the AMR26 fairly high up the order, though it inevitably plummeted as the race continued.
Still, the prevailing view at Aston Martin’s is increasingly clear – a solid engine will unlock the AMR26. To achieve this goal, Honda have an important engine upgrade incoming.
The limiting factor for Aston Martin
It seems slightly nonsensical to say Aston Martin can take positives in a weekend where the AMR26 was so troubled. However, in these unique circumstances, there were some encouraging signs for the British team.
Fernando Alonso’s qualifying, where he finished in 17th (2.4 seconds off P1) was a pleasant surprise. Given how poor Aston’s performance looked in Friday Practice, their 2026 challenger was actually more competitive than anticipated.
Initial projections had Aston Martin around 4 seconds away from the very front.
Speaking post-qualifying, Alonso suggested this step forward is evidence of the car’s potential. The Spaniard mentioned that Aston unlocked two seconds between FP2 and qualifying purely by making set-up changes.
This demonstrates how limited Aston Martin’s track time has been in 2026 so far. Due to the Honda engine’s excessive vibrations, the AMR26 has not spent anywhere near enough time collecting data.
By extension, when the car is on track, the Honda power unit becomes a significant handicap. This results in a car that quickly runs out of battery deployment, and therefore goes far slower than it should be.
This is particularly damaging because it prevents Adrian Newey’s technical team from seeing how their 2026 car actually behaves.
Since the car is not pushed towards its limits (and is going especially slowly into high-speed corners) its aerodynamic performance and behavioural characteristics cannot be determined.
To make things worse, Aston Martin are forced to run with high fuel loads.
This counter-measure helps to mitigate the engine’s excessive vibrations, thereby depriving the British team of truly carrying out low-fuel runs.
When taking into account all these factors, Newey’s team believes the AMR26 is far more competitive than it looks.
The prevailing view is that even a slightly more reliable engine – durable enough for the team to stop doing excessive management – will unlock a huge amount of performance.
Therefore, the limiting factor in Aston Martin’s 2026 success will be the Honda power unit. This is not to say there aren’t other areas to optimise. At this stage of the season, everything can be improved.
Still, only when Honda’s engine gets in order can the team truly assess where they stand. On this front, a potentially season-defining upgrade is in production. (continues on next page)
