The beginning of the primary wet-weather race of the 2026 System 1 season descended into chaos. Chief Max Verstappen was the primary to endure from a scarcity of energy whereas driving slowly in the course of the formation laps behind the protection automobile, after which Lewis Hamilton got here to a standstill and a number of other different vehicles adopted.
Race management was compelled to cease the formation lap with a purple flag, after which there was a 40-minute delay earlier than followers really acquired to see some F1 motion.
FIA single-seater director Nikolas Tombazis confirmed to media together with Autosport {that a} bug within the software program provided by the FIA and developed along with the groups over the course of a number of years was answerable for the chaos.
“We did not handle to check the software program as extensively as we might have favored as a result of there’s been little or no moist working this 12 months. There was a little bit of a mix of circumstances which brought on this bug to kick in,” Tombazis mentioned throughout an impromptu media session post-race.
“Mainly, on the formation lap, some vehicles went very slowly and nearly got here to a standstill. There was a little bit of a concertina impact between vehicles and a few vehicles nearly stopped fully. That bug prevented then the ability to be redeployed and for the vehicles to begin once more.”
That is intently associated to the discount in electrical energy to 250kW in moist circumstances.
Though the software program required for this was examined by a number of groups, together with Crimson Bull and Racing Bulls, it was not examined within the circumstances behind the protection automobile – and due to this fact not at these extraordinarily low speeds.

On the Sepang Worldwide Circuit, these low speeds have been reached in sure minisectors, with all the implications that adopted.
“It was primarily in some sectors the place the complete energy was diminished. I do not know precisely what velocity that was, however some vehicles reaching this very low velocity one way or the other entered right into a loop, which meant they could not re-accelerate after which it appeared as in the event that they got here to a cease.”
In apply, this left drivers feeling as if the throttle pedal was not responding, one thing Oliver Bearman advised the media with some shock.
“I’ve by no means seen or felt something like that. I used to be shocked that… I did not even know that the FIA might management our throttle pedal. That was fairly scary, really,” the Haas driver mentioned.
“My throttle pedal simply stopped working. It was prefer it was not linked and the engine was simply idling. It was so bizarre, I imply, stunning.”
One of many questions is why the inner combustion engine was additionally affected, when that shouldn’t be the case at extraordinarily low speeds. The FIA doesn’t but have a proper reply to that query, however the preliminary suggestion is that the bug brought on all throttle enter to go in direction of recharging the MGU-Ok, which explains why drivers felt there was no response from the throttle pedal in any respect.
At first look, it appeared as if the Mercedes-powered vehicles have been much less affected by the difficulty than different producers, however Tombazis defined that there isn’t any technical motive for that. It was merely associated to the speeds reached in sure minisectors.

“Not all vehicles reached the identical low speeds on the formation lap. There was a little bit of a concertina impact. I feel Max slowed down rather a lot, being on the entrance, after which some vehicles braked more durable as they have been shocked and so forth. That brought on some vehicles to expertise the issue and a few others to not expertise it.”
How the FIA offered F1 groups with an emergency repair
The FIA then needed to react shortly to get the race close to Kuala Lumpur beneath means in spite of everything, as Tombazis defined when requested by Autosport.
“Fortuitously, our guys understood the difficulty very, in a short time. I feel the replace was finished very competently. It was clearly a rush job. The precedence was to get working as shortly as doable once more, so I feel the response time was fairly quick,” he mentioned.
“It wasn’t an ideal job and, clearly, we did not check the updates, however I feel it was the way in which to deal with such a case.”
In apply, the replace meant that the FIA lifted the power restrict constraint – the restrictions related to the 250kW restrict – for the minisectors through which the low speeds had triggered the bug. Logically, this isn’t a watertight resolution going ahead, but it surely was an emergency measure to make sure the race might go forward.
“In among the sectors, a few of these reductions of energy have been overridden,” Tombazis confirmed. “Clearly, we did not have 5 days to do the updates. We solely had a couple of minutes, however luckily, I feel we managed to do it with out compromising any security, any racing or equity.”
How might this occur within the first place?
After the FIA replace, all of the groups nonetheless needed to set up the modified software program, which explains the delay earlier than the restart. The Bahrain Grand Prix in Malaysia was saved consequently, however that also doesn’t clarify how the FIA might have missed this subject all through all its preparations and why it solely surfaced in spherical 16 of the championship.
“The software program was examined. It simply wasn’t examined in these particular circumstances,” Tombazis replied. “What caught us out was the truth that vehicles went in that very, very low velocity, which was not usually contemplated.”

Throughout the tyre assessments through which the software program was examined, the extraordinarily low speeds have been understandably not reached. Nonetheless, there’s a essential counterargument to that: within the rain, the probability of a security automobile – and due to this fact low speeds – could be very excessive. Ought to the FIA not have anticipated that, and was that the governing physique’s largest mistake?
Requested that query by Autosport, Tombazis responded: “Properly, any bug is a product of a mistake. I do not know of any software program that does not have bugs and updates. Your pc in all probability will get up to date each three days and people are all bugs.
“After all, anticipating these items is what one hopes to do, however generally some very mixture of occasions is not correctly anticipated and causes the issue. I feel if we had had a bit extra testing, we in all probability would have managed to catch it in time and to not have such a scenario.”
Though the reason for this drawback is now recognized and a short lived repair has been launched, the FIA nonetheless has many inquiries to reply internally – additionally to make sure that it doesn’t occur once more.
“We might all prefer it to be less complicated, however the reality is when you’ve got as a lot electrical power, it does make it extra difficult. I feel you respect that the race has now completed about one hour in the past and we’ve not finished a full debrief of the scenario to see how we are able to keep away from such a problem.
“Each race, now we have a protracted debrief afterwards the place we determine criticalities. Clearly, that was a significant criticality and we’d like to verify we keep away from it.
“However can I assure it can by no means occur once more? This particular drawback, sure. An issue, no. However we are going to do our greatest to keep away from it, after all.”
