Aston Martin and Honda Battle AMR26 Woes, But Two-Second Gap Remains Daunting

Aston Martin and Honda are making headway on the issues plaguing the AMR26, but the car remains at least two seconds off the pace in qualifying. Reliability problems early in the season delayed track time, while vibrations and abrupt gearshifting have hindered driver confidence. Fernando Alonso says fixing the drivetrain finesse might gain only half a tenth, not the missing seconds.

Why it matters:

Aston Martin's ambitious design, led by Adrian Newey, aimed for aerodynamic gains through aggressive rear-end packaging. However, the compromises—including a novel double-deck battery and relocated electrical motor—have created knock-on reliability problems. The team is learning on the fly after curtailed testing, and the gap to Mercedes-powered rivals remains stark.

The details:

• Driveability fixes limited: Alonso stated that smoother downshifts and engine braking would improve confidence but not performance. “Maybe half a tenth,” he said. He called driveability the "number one" priority for Canada.
• In-house gearbox: For the first time since the late 2000s, Aston Martin built its own gearbox. Integration with Honda's power unit—especially under new 2026 regulations—adds complexity.
• Honda's progress: Chief engineer Shintaro Orihara said battery reliability is now resolved. The focus is on energy management and controlling the unique behavior in partial throttle and engine braking phases under new regulations.
• Engine deficit: Beyond driveability, the Honda unit is short of the benchmark Mercedes in horsepower and electrical deployment. That alone accounts for a significant chunk of the time loss.

What's next:

The team is iterating on software and control strategies to tame the powertrain. But as Krack noted, new issues emerge as old ones are solved. Real performance gains will require a more powerful engine and aero optimization—both likely months away. The short-term goal is simply to maximize track time and gather data.

Meanwhile, Alonso remains pragmatic: “We need to improve, but we won't find two seconds from driveability.”
