F1 Cars Got Stuck in Idle. The Fix Was a Software Patch

At the rain-hit Bahrain Grand Prix (held in Malaysia, at Sepang) on October 4, Formula One cars lost power behind the safety car on the formation lap. The cause was a bug in the wet-weather energy software every team has to run, and the FIA, which supplies that software, pushed a fix to the whole grid while the race was halted. Here's how a 1,000 hp car gets stuck in idle, and who shipped the bug. Should the cars that stalled have been allowed to restart, or was Alonso right? As of October 8, 2026. The FIA has promised a full review with the teams and engine makers and had not published findings. Why the petrol engine was affected has no formal answer yet; the throttle-to-recharging explanation is Motorsport.com's report of the initial suggestion. GPblog argues the re-upload technically breached parc ferme; the rules allow changes for weather. SOURCES Formula1.com, race report: https://www.formula1.com/en/latest/ar...
