The first round of pre-season testing for the Fórmula 1 in 2026 ended with a scenario of genuine concern for two specific teams on the grid. Aston Martin and Cadillac left Circuito of Enquanto the new technical regulations for engines and aerodynamics promised a revolution in the category, practical reality showed that reliability is still a severe obstacle for projects fresh from the drawing board.
The activities carried out between Wednesday and Friday revealed patterns of breaks that prevented full compliance with the schedules planned by the engineers. Cadillac, which makes its official debut as the 11th team in the championship, faced difficulties in keeping its cars in constant operation during the morning and afternoon sessions. On the other hand, the Aston Martin, now powered by the Honda engines, recorded the lowest mileage among all competitors, showing a significant delay in relation to direct opponents in the development of the AMR26 model.
The data collected over the three days of testing points to a considerable technical disparity at the start of this new era of competition. Durante the track work, it was observed that:
- The total mileage of the Aston Martin was just 206 laps, the worst rate on the grid.
- The Cadillac totaled 320 spins, ahead of only the Alpine, Mercedes and Aston Martin.
- The Cadillac’s lap time was 3 seconds behind the leaders in specific sessions.
- Engine failures and overheating were the main reasons for outages in garages.
Technical difficulties mark the debut of Cadillac in the category
The North American team Cadillac experienced intense and problematic days in their first official track experience on the modern Fórmula 1. On Thursday, driver The incident limited the Mexican’s track time, although his teammate, Valtteri Bottas, managed to record the eighth fastest time that same day, showing flashes of potential.
Friday, however, brought new setbacks for the operation led by Graeme Lowdon, with Bottas being parked early in the morning due to mechanical problems. The Finn only managed to return to the asphalt in the final hour of the session, totaling just 37 laps in his driving shift. Apesar of Pérez’s effort in the afternoon to make up for lost time, the team ended the week with the fourth lowest total mileage, highlighting the team’s lack of resistance.
Ferrari power unit performance in contrast
Although Cadillac uses engines supplied by Ferrari, the American team’s performance contrasted sharply with the results obtained by Haas, another customer of the Italian manufacturer. The Haas demonstrated impressive solidity, accumulating 390 laps without registering any type of serious failure with the drivers Oliver Bearman and Esteban Ocon. Essa reliability difference suggests that the Cadillac problems may be more linked to the integration of the chassis and peripheral systems than to the power unit itself.
Team principal Graeme Lowdon has sought to remain calm in his public statements, stating that the car serves as a basic platform for future development. Ele highlighted that despite the setbacks that curtailed race plans, feedback from drivers on the handling has been positive and accurate. Lowdon emphasized that serious drivability problems would be more worrying than reliability failures at this embryonic stage, treating incidents as part of a debut team’s learning process.
Performance crisis and internal frustration at Aston Martin
The situation at Aston Martin seems even more delicate, with strong statements coming from its main protagonists after the end of testing. Lance Stroll did not hide his pessimism when stating that the team appears to be around four seconds behind the top teams at the moment. The Canadian driver even mocked the technical situation, commenting that the new car’s paintwork was the only visible positive point of the project so far, which generated immediate repercussions behind the scenes.
Fernando Alonso also showed clear signs of irritation, being seen in the pits in moments of visible frustration during Thursday’s sessions. The two-time world champion had previously warned about the difficulties expected at the start of the season, focusing his hopes on an evolution for the second half of 2026. The arrival of Adrian Newey to the technical team has not yet had the expected immediate effect, with the designer himself admitting that the development schedule is months behind schedule.
Rumors about the Honda engine and the cooling challenge
Speculation in the paddock indicates that the main bottleneck of the Aston Martin lies in the new power unit developed by Honda, which replaces Mercedes as supplier. Relatos point out that the engine would be suffering from constant overheating problems, which forces the team to operate the equipment below the ideal speed to avoid permanent breakdowns. Embora Alonso has publicly denied that the engine is solely to blame, the recent history of statements from Honda leadership confirms that development did not follow the original plan.
The integration between the AMR26 chassis and the Japanese engine has proven to be a complex challenge, requiring drastic changes to the internal aerodynamics to improve airflow. Mike Krack, track director, recognized that the level of work required to catch up to competitors is immense and that the team has not yet reached the desired level of competitiveness. Ele reiterated that the package has latent potential, but that exploiting this performance will require redoubled effort in the weeks leading up to the first official race.
Perspectives for the sequence of pre-season work
The Fórmula 1 schedule foresees the continuation of activities at Bahrein next week, with live broadcasts scheduled to follow the teams’ progress. Para Cadillac and Aston Martin, the next few days will be crucial for carrying out emergency adjustments to systems that have experienced critical reliability failures. The focus will temporarily move away from the search for fast lap times to prioritize keeping the cars on the track for as long as possible, with the aim of collecting the data necessary to refine the projects.
Engineering teams at Silverstone and at the Cadillac base must work in uninterrupted shifts to process the telemetry information obtained in this first round. The pressure for results is high, especially considering the massive investment made by Aston Martin in infrastructure and in hiring renowned technical talent. The current scenario shows that, in a regulation as complex as that of 2026, previous experience and efficient systems integration are worth as much as boldness in aerodynamic design.
Expectation of constant evolution
The nature of the pre-season allows rapid developments to take place between one week of testing and the next, but the mileage deficit accumulated by Aston Martin and Cadillac represents a loss of precious time. Cada volta não completada significa menos dados sobre o desgaste de pneus, consumo de combustível e comportamento térmico dos componentes sob condições de corrida. The race against time is now the main opponent of these two teams, who need to prove that their concepts are viable before the official opening of the championship.
