Aston Martin began the 2026 season with a catalogue of technical weaknesses that left the team struggling on track and braced for more poor results. Drivers and engineers have logged deficits across the car, and Fernando Alonso called Monaco “zero positives,” warning fans to expect “another four or five races of painful results.” The team reported severe mid-corner understeer in low-speed turns, which it said is a deeper problem than a simple setup issue.
Alonso and team engineers flagged specific failures in the opening rounds: an engine power shortfall in Australia, an energy deficit in China, a chassis weakness revealed at Monaco, and gearbox troubles in Canada and Miami. The team says these issues affected the whole package rather than being isolated to a single area.
Development timing and a power-unit change contributed to the struggles. Aston Martin arrived late to winter testing after switching from customer Mercedes engines to a works Honda power unit. The new Honda unit suffered power and reliability shortfalls early in the season; team ambassador Pedro de la Rosa said Honda’s reliability had recently improved, but the overall package still lagged.
Adrian Newey, who joined as managing technical partner and has since been promoted to team principal, said the team’s new wind tunnel only produced a model in mid-April 2025. He said that delay produced roughly a four-month development setback after the aero-testing ban ended in January 2025. The team said it must make the most of the ADUO (a mechanism allowing limited in-season power-unit development) and expects larger upgrade packages in the second half of the year.
Monaco underlined the performance gap: Aston Martin qualified 21st and 22nd, more than three seconds off Mercedes pole-setter Kimi Antonelli. Alonso climbed from 21st to 10th and secured the team’s first championship point of 2026 after a post-race penalty for Sergio Pérez and several incidents opened a rare opportunity. The result owed much to an aggressive one-stop strategy amid two safety cars, a red flag and seven retirements. De la Rosa called the lone point “special,” suggested the chassis could be as quick as the fifth-fastest package at some circuits, and urged patience and unity while the team prepares upgrades and further analysis to determine whether the understeer will persist.
