Torrential Rain and Software Failures Halt Formula 1 Bahrain Grand Prix in Sepang

Monsoon downpour halts Malaysian start

The start of the 2026 Bahrain Grand Prix at the Sepang International Circuit was delayed on Sunday morning following torrential monsoon rainfall. The race, representing the sixteenth round of the Formula 1 World Championship, was originally scheduled to begin at 09:00 Italian and Spanish time. Heavy precipitation flooded multiple sections of the track north of Kuala Lumpur, creating deep standing water that compromised vehicle handling. The safety car and medical car both struggled with aquaplaning while assessing the asphalt during reconnaissance runs.

The medical team reports that there is a considerable amount of standing water around the circuit. The current conditions are not suitable to start the race.

Race officials postponed the start while waiting for track drainage to improve, noting that downpours remained steady across the venue.

The intensity of the rain has remained constant over the last 10 minutes and no improvement is expected for the next 5 to 10 minutes.

Software failures strike formation lap

Approximately 40 minutes after the scheduled start time, race control initiated a formation lap behind the safety car to evaluate track drivability. During the two planned evaluation laps, several cars encountered severe technical disruptions. Ferrari-powered vehicles suffered sudden software and electrical communication shutdowns caused by the extremely low speeds maintained behind the safety car. Lewis Hamilton was the first driver affected when his Ferrari stopped completely on the racing line, forcing following drivers to overtake him. Hamilton was able to restart after his pit wall executed a remote software reset. Shortly afterward, both Haas drivers, who also use Ferrari power units, stopped along the track edge with identical software communication failures. With disabled cars stranded around the circuit, race control waved red flags, suspended the start procedure, and recalled all remaining cars to the pit lane.

Relocation context and qualifying order

The event is taking place in Malaysia rather than Sakhir because the Bahrain Grand Prix, originally scheduled for April, was relocated due to the military conflict between Iran and the United States in the Middle East. The move returned Formula 1 to Sepang for the first time in nine years after dry weather had held throughout the practice week. Saturday qualifying established Max Verstappen on pole position after the Red Bull driver set a lap time of 1:35.130. Hamilton qualified second, finishing 0.298 seconds behind Verstappen. Isack Hadjar recorded the third-fastest time for Red Bull but incurred a five-place grid penalty for changing power unit components. Drivers championship leader Kimi Antonelli qualified fourth for Mercedes, followed by Charles Leclerc in fifth, Lando Norris in sixth, Oscar Piastri in seventh, and George Russell in eighth.

Grid status and restarting procedure

Following the red flag and pit lane recall, the FIA confirmed that the original qualifying order will remain valid for the eventual standing or rolling start. Max Verstappen retains pole position alongside Hamilton on the front row, while Spanish drivers Fernando Alonso and Carlos Sainz will start from 12th and 13th positions respectively. Mechanics in the pit lane were permitted to work on the cars and reset electronic systems while drivers waited under umbrellas in their garages. Race control has not yet announced an official revised restart time as teams await improved track drainage.
