Software Bug Causes ‘Lego Race’ Chaos at Bahrain GP

Published: October 4, 2026, 11:27 pm

The Bahrain Grand Prix held in Malaysia descended into chaos after a software malfunction crippled multiple cars just before the race start. The technical failure, which stripped vehicles of their speed, prompted Max Verstappen and Lewis Hamilton to compare the bizarre scenes to a “Lego race.” The issue stemmed from a bug within the engine software responsible for managing electrical power deployment during wet conditions. Audiences were treated to the bizarre sight of many of them struggling to move, and when the cars set off on formation laps behind a safety car to test the conditions. Low grip and specific aspects of the circuit layout, a bug in the software that mandates how the engines’ electrical power can be used in wet conditions had been triggered by a combination of low engine speeds. I had to stop on track and stop the car and engine and restart it.

A tropical downpour had already forced an hour-long delay to the start of the race. When the event finally commenced, the software error triggered a loss of momentum for several drivers, including those starting on the front row. Verstappen, who ultimately claimed his first victory of the 2026 season, described the experience as insane, noting that at one stage the field was five-wide on the straight because engines were struggling to maintain pace. Hamilton, who finished third, joined the Red Bull driver in the post-race conference to confirm he had also experienced the issue, remarking that he had never encountered such a situation before. Largely because there has been so little running in the wet this year.

Verstappen noted that he initially triggered the problem and was left confused in his cockpit, questioning if the rest of the field was waiting for him. He later compared the visuals of the struggling cars to a show run featuring battery-powered Lego F1 models held at the British Grand Prix earlier this year. Mercedes driver George Russell, who was forced to retire from the race due to an engine failure, commented that the overall experience did not feel like a typical Formula 1 event. I triggered (the problem) first and then I looked in my mirror, I was like: ‘Wait, are they waiting for me or what’s going (on). And I saw you (Hamilton) by yourself crawling, then we did a lap and then I see eight other cars crawling still.

Nikolas Tombazis, the FIA’s single-seater director, acknowledged that the governing body would conduct a full investigation. He explained that the software had undergone testing but had not been evaluated under these specific, high-complexity conditions. While admitting that the sport aspires for simplicity, Tombazis emphasized the inherent difficulty of balancing electrical and combustion energy while ensuring sporting fairness between teams. He stated that a full debrief is required to prevent a recurrence, though he stopped short of offering a guarantee that such failures would never happen again.

The incident highlights the ongoing challenges introduced by this year’s hybrid engine regulations, which demand a near 50-50 split between internal combustion and electrical power. These engines are fundamentally energy-starved, often leading to complex, counter-intuitive driving behaviors that have sparked complaints throughout the season. Rules are already slated to change next year to address these energy-management issues.

McLaren team principal Andrea Stella reflected on the event, noting that while the start was not ideal for the sport’s presentation, the technical hiccups are perhaps inevitable during the first year of such complicated new regulations. He praised the broader efforts to make the racing competitive despite these early hurdles.

Beyond the software glitches, the race marked a significant turning point for Red Bull. Verstappen’s victory, his 72nd in Formula 1, capped a dramatic comeback for the team. After a difficult start to the year that saw them struggle as the fourth-fastest team, performance-related clauses in Verstappen’s contract had sparked speculation about his future. However, the Dutchman opted to stay, citing his faith in the team’s ability to recover. Following a string of recent upgrades, including a new floor introduced in Baku, Red Bull has finally found the pace required to challenge for the front, proving that their recent competitiveness is more than a temporary surge.
