The 2026 Formula 1® Bahrain Grand Prix, held at Sepang in Malaysia, faced an unexpected delay as multiple cars encountered power unit issues during the formation laps. The wet track conditions, caused by a heavy tropical thunderstorm, contributed to a chaotic start, leading race control to suspend the race and display a red flag.
Several teams were affected by these technical problems, including Red Bull Racing, Ferrari, AlphaTauri, Audi, and Cadillac. Key drivers such as Max Verstappen, Lewis Hamilton, Liam Lawson, Gabriel Bortoleto, and Valtteri Bottas experienced difficulties related to their power units, which were suspected to be software-related gremlins rather than confirmed mechanical failures.
Max Verstappen, who had secured pole position, initially reported acceleration issues but was able to recover and continue during the formation laps. Similarly, Lewis Hamilton faced power unit problems that caused him to move slowly during the first formation lap before regaining normal performance. Other drivers, including Liam Lawson, Gabriel Bortoleto, and Valtteri Bottas, also reported similar issues, highlighting the widespread nature of the problem.
The race was set to be the first wet event under the 2026 regulations, with the tropical storm leaving the track conditions challenging. The start procedure was halted as the affected cars returned to the pitlane, resulting in a mixed grid. Race control indicated plans to revert to the original grid positions once the race resumes, but no detailed timeline has been provided.
At this stage, no official statements have been released by the teams or drivers regarding the precise cause of the power unit issues beyond the suspicion of software-related faults. The situation remains fluid, with further updates expected as the event progresses.
This disruption underlines the complexities teams face when adapting to new regulations and challenging weather conditions. The Bahrain Grand Prix in Malaysia is notable for being the first wet race under the updated technical framework, and the power unit issues experienced during the formation laps have highlighted potential areas for further investigation.
As the situation develops, the focus remains on resolving the technical problems to allow the race to proceed safely and fairly. The incident serves as a reminder of the ongoing challenges in managing advanced power unit systems in variable conditions within the Formula 1® championship.
