10 F1 cars suddenly limited to 30 km/h because of a software bug.
The bizarre incident where multiple Formula 1 cars were suddenly slowed to a crawl of around 30 to 35 km/h occurred during the formation lap of the Bahrain Grand Prix (hosted at the Sepang Circuit in Malaysia due to a scheduling twist).
What Caused the Glitch?
The farce was triggered by a software bug embedded in the mandatory power-unit control software supplied by the FIA. Under the 2026 technical regulations, cars are programmed with a safety-oriented wet-weather engine mode that automatically restricts electrical hybrid power deployment from 350 kW down to 250 kW to prevent sudden spikes in torque on slippery surfaces.
