FIA to Investigate Software Bug That Limited F1 Cars in Malaysia

What changed

A software bug made multiple Formula 1 cars lose or limit power in the wet conditions before the Bahrain Grand Prix in Malaysia. Max Verstappen and Lewis Hamilton said the formation laps looked like a “Lego race”; Verstappen won, Hamilton finished third, and Mercedes’ George Russell retired with an engine failure.

The FIA will investigate. The bug affected software controlling electrical power when engine speeds and grip were low, alongside specific features of the circuit.

Why it matters

The bizarre sight of cars crawling behind the safety car was not just a rainy-day embarrassment. It exposed how tightly modern F1 performance depends on software deciding when the hybrid system can deliver power.

The cars had been tested, but not in this particular combination of low grip, low engine speed and circuit layout. That gap mattered immediately: drivers could not simply drive through the problem. Hamilton had to stop, switch off the car and restart it.

That makes this a sporting issue as much as a technical one. A system intended to manage wet-weather electrical power instead left several front-running cars struggling to move, while drivers tried to work out whether everyone else was having the same problem.

The wider problem is already shaping the championship. This year’s hybrid engines split power almost evenly between combustion and electricity, but they cannot always deploy their full combined output. Rules will change next year to alter that balance. The investigation should show whether this glitch was an isolated software failure or another sign that the power-management rules have become too complicated for the conditions F1 actually races in.

The FIA says it can prevent this specific problem from returning, but cannot promise that no other software issue will emerge. That is a modest guarantee, and probably the honest one. Modern F1 may be the fastest racing in the world, but for nearly an hour in Malaysia, its most advanced cars behaved like they had forgotten how to start.
