Fernando Alonso's Canadian Grand Prix retirement stemmed not from mechanical failure, but severe back pain caused by Aston Martin's reclined seating position. The AMR26’s cockpit design, made more laid-back this season, aims to lower the center of gravity and reduce helmet turbulence for performance gains.
