The Honda power unit causes a 1.5 second per lap deficit for the Aston Martin AMR26. This performance gap prevents the team from using the aerodynamic advantages of the chassis designed by Adrian Newey. Severe vibrations from the engine cause physical issues for the drivers. Lance Stroll manages only 15 laps before the vibrations become problematic. Fernando Alonso can complete roughly 25 laps before experiencing similar issues. These vibrations also cause rapid battery wear and broken components. The team spends track time fixing reliability issues instead of improving speed.
The AMR26 remains unreliable.
The technical leadership at Silverstone
Lawrence Stroll invests heavily in the team infrastructure. He built the AMR Technology Centre and a new wind tunnel at Silverstone. Andy Cowell became the Chief Executive Officer on 1 October 2025. Enrico Cardile serves as the Chief Technical Officer. Adrian Newey works as the Managing Technical Partner. He earns a salary that reaches £30m with bonuses. Newey began his role on March 1 2025. He has 13 drivers’ championships and 12 constructors’ titles. Newey worked with the teams at Williams, McLaren, and Red Bull. He helped win championships in 1992, 1993, 1994, 1996, 1997, 1998, 1999, 2010, 2011, 2012, 2013, 2021, 2022, and 2023. His arrival in 2025 followed a negotiation with Red Bull to leave his role as chief technical officer. Dan Fallows serves as the technical director. He worked under Newey at Red Bull from 2006 until 2021.
Technical specifications for the 2026 season
The 2026 regulations mandate a 50/50 split between electrical power and the internal combustion engine. The removal of the MGU-H forces engineers to manage energy through the MGU-K. Teams must use 100% sustainable fuel.
| Feature | 2026 Regulation Detail |
|---|---|
| Power Split | 50% Electrical / 50% ICE |
| Fuel Type | 100% sustainable fuel |
| MGU-H Status | Removed from regulations |
| 2026 Cost Cap | $215 million |
| Newey Salary | £20m to £30m |
| Alonso Contract | Until the end of 2026 |
The complex transition to these rules creates difficulty for manufacturers. Honda is working on an engine upgrade for Zandvoort to improve the internal combustion engine.
Physical limits for Alonso and Stroll
Fernando Alonso is 45 years old. He has not won a race since 2013. His contract with Aston Martin lasts until the end of 2026. Lance Stroll faces pressure to provide feedback on a fragile car. Stroll finished third at the Azerbaijan Grand Prix as a rookie. He was the youngest driver to finish on a podium at age 18. Stroll drove for Williams in 2017 and Racing Point from 2019 to 2020. He scored his first points in Montreal and had a podium in Italy. You know the physical toll of a heavy car. Stroll also had collisions with Sebastian Vettel and Carlos Sainz Jr. in his earlier career.
Honda engineering and historical context
Shintaro Orihara, Honda’s trackside general manager and chief engineer, said the team realized the scale of performance and reliability problems in January. The team found performance was inconsistent. The removal of the MGU-H makes maintaining boost pressure difficult. Honda re-entered the sport in 2026. They previously supplied McLaren from 2015 to 2021. They also supplied Toro Rosso in 2018. Red Bull used Honda as a works partner from 2019. Honda left F1 at the end of 2021. The company noted its interests as a car manufacturer were better represented elsewhere.
Honda struggles.
The engine vibrations remain a problem. The team is trying to fix the issue through the chassis. Honda has a deep history with hybrid technology. They want to use F1 to test sustainable energy systems for everyday vehicles.
Financial compliance and Stroll’s investment
Lawrence Stroll spends more than his original budget. He spent money on engineers and facilities. The F1 cost cap for 2026 is $215m. Aston Martin had a procedural breach in 2024. This breach involved an administrative delay regarding an auditor signature. The FIA confirmed the team stayed within the $135m limit for 2024. The FIA maintains flexibility to judge breaches individually, rather than using a one-size-fits-all approach when they evaluate if a team exceeded the spending limits set for the season. Driver salaries and the pay for the three highest-earning staff members are not part of the cap.
Manufacturing changes at Silverstone
Aston Martin is building its own gearbox. They no longer buy this component from Mercedes. This change follows the end of their exclusive engine and component supply deal. The team brings all parts for manufacture in-house at the Silverstone facility. This facility is now fully operational. The team works to integrate the Honda power unit with the chassis.
The roadmap to recovery
The team must stabilize the power unit to use the Newey chassis. Improving the internal combustion engine is the priority for the Zandvoort upgrade. The gap to the front-runners remains large. The team spent its development budget on reliability fixes. Will the Zandvoort upgrade fix the ICE deficit?
The partnership is a long-term project.
