Honda's power unit lasted only five laps during the Formula 1 Mexico Grand Prix, according to reports from the event. The Japanese manufacturer's engine suffered an early failure that forced a premature retirement, raising questions about reliability at the high-altitude Autódromo Hermanos Rodríguez circuit.
Details regarding the specific cause of the failure and which team or driver was affected were not immediately available. The Mexico City circuit's elevation of over 2,200 meters places unique demands on power unit cooling and performance, which has historically challenged manufacturers.
Honda, which supplies power units to Red Bull Racing and Visa Cash App RB, has generally shown strong reliability in recent seasons. The early exit represents a rare setback for the Japanese manufacturer's F1 program as it prepares for its final season before new regulations take effect in 2026.
