The biggest disappointment of the first half of the 2026 Formula 1 season has undoubtedly been Aston Martin. Following Lawrence Stroll‘s enormous investment in expanding the Silverstone-based team’s facilities and recruiting some of the sport’s brightest engineering minds—most notably Adrian Newey—the team was widely expected to emerge as one of the championship contenders this year.
However, it became clear from the very first private pre-season tests at the Circuit de Barcelona-Catalunya that the AMR26 project was facing far more than just delays in assembling the new car. The Silverstone outfit has endured a difficult campaign due to the significant shortcomings of the Honda RA626H power unit, combined with an aero-mechanical package that has failed to live up to the expectations associated with Adrian Newey’s renowned expertise.
The statistics from the opening phase of the championship paint a bleak picture. Aston Martin’s green cars have consistently occupied the back of the grid and have completed the fewest laps of any of the eleven Formula 1 teams across the first nine race weekends of the season.
A new specification of the Honda power unit is expected to make its debut at the Dutch Grand Prix, thanks to the opportunity provided by the latest homologation regulations under the ADUO framework. Engineers at Honda’s Sakura facility, where the Formula 1 engines are developed and built, are aiming to significantly improve reliability while recovering at least part of the substantial performance deficit that has plagued the team.
The scale of Aston Martin’s struggles is highlighted by the qualifying figures. On average, the team’s fastest qualifying lap has been approximately 3.5 seconds slower than pole position. Honda General Manager and Trackside Chief Engineer Shintaro Orihara recently outlined the Japanese manufacturer’s strategy to improve the competitiveness of its Formula 1 power unit.
The Japanese executive confirmed that the updated RA626H specification is scheduled to debut during the Formula 1 weekend in the Netherlands. Honda is focusing its efforts on redesigning both the combustion chamber and the pre-chamber geometry. The primary objective is to improve reliability, because as performance increases, ensuring durability becomes an even greater engineering challenge.
Over the past few weeks, the upgraded engine has undergone extensive dynamometer testing. Individual cylinder testing has already been completed, while the latest modifications are currently being validated with the complete V6 power unit on Honda’s full-scale engine test bench. Orihara also revealed that engineers are carrying out additional evaluations of energy consumption during transient operating conditions.
Honda’s chief engineer declined to reveal the power figures recorded during the bench tests, although he expressed confidence in the progress achieved so far. He acknowledged that the new specification will not be a miracle cure for all of the team’s current problems, but stressed that it is intended to provide a solid technical foundation from which the RA626H power unit can continue its long-term development.
It is also clear that a significant portion of Aston Martin’s future performance improvements will have to come from aero-mechanical development. Adrian Newey admitted that work on the 2026 car only began in mid-March 2025. That considerable delay prevented the team from exploring alternative design concepts and ultimately forced engineers to commit too quickly to an aerodynamic package that proved overly ambitious.
The legendary British designer also explained that the chassis is substantially overweight because of the integration requirements of the power unit and the need to manage vibration levels effectively. The second half of the 2026 Formula 1 season will reveal whether Honda and Adrian Newey have learned from their respective mistakes and whether they can begin looking towards the medium-term future with renewed confidence.
