Alonso's Canadian GP retirement traced to AMR26's reclined cockpit position

Fernando Alonso retired from the Canadian Grand Prix at Circuit Gilles Villeneuve on lap 23 of 68 after suffering increasingly severe back pain linked to the AMR26’s cockpit geometry. Aston Martin’s chief trackside officer Mike Krack confirmed the cause was a more reclined seating position introduced for the 2026 car, a deliberate design choice aimed at lowering the centre of gravity and reducing the driver’s helmet exposure to airflow.

Alonso described the discomfort as cumulative and ultimately unbearable. “I felt increasingly uncomfortable,” he said. “The position wasn’t right and since we were out of the points, far from the points zone, and with no threat of rain, we decided to put an end to the pain. We tried to adjust a few things last night, but it didn’t work.”

Between Saturday and Sunday, Aston Martin technicians worked with Alonso to modify the seat itself — a carbon fibre unit moulded to the driver’s body — to determine whether the problem lay with that specific component. It did not. The seat showed no defect, pointing instead to the fundamental cockpit layout as the root cause.

Onboard footage from the race illustrated the severity of the issue, showing Alonso repeatedly moving his left hand from the steering wheel toward the inside of the cockpit between corners, including on the straight before the final chicane and approaching Turn 8.

Krack noted that the Circuit Gilles Villeneuve kerbs compounded the problem. Drivers use the kerbs more aggressively in Montreal than at most other venues, and the resulting vibrations amplified the pressure on Alonso’s back with every passing lap. “He hasn’t felt completely comfortable for a while now — never to the point of becoming a real obstacle, but it’s like a pressure point that gets worse lap after lap,” Krack said. “I think we need to reconsider the seating position a bit.”

The retirement was particularly costly given the context. Montreal had shaped up as Aston Martin’s strongest weekend of a difficult 2026 campaign. Alonso had reached SQ2 in sprint qualifying and was running inside the top ten during the grand prix before the back pain forced the team’s hand. The broader picture for Aston remains troubling, with the AMR26 carrying well-documented issues centred on its power unit alongside this newly surfaced ergonomic concern.
