SINGAPORE (AP) — The FIA has defended its handling of the Formula 1 car software bug which delayed the start of the Bahrain Grand Prix in Malaysia last weekend and pledged it will “strengthen” how the code is tested in future.
Several drivers, including seven-time champion Lewis Hamilton, were left stuck on track
when their cars lost power and had to be restarted on formation laps before Sunday's race.The on-board software failed to cope with drivers
taking a more cautious approach ahead of the first wet race for the 2026 cars, which have a near 50-50 split between engine and electrical power.
The FIA, the governing body for F1, on Thursday said its investigation found that cars “experienced a loss of power beyond the original intent and that could not be recovered.”
After the cars were stuck on track, the start was suspended as the FIA rushed out a software update. The race eventually started almost an hour later, with no obvious software-related incidents, though the track had dried much more by then.
The FIA says that update will be used again if it rains at this week's Singapore Grand Prix — the forecast says that's likely — with more changes at the following race on Oct. 25.
“As a result, the configuration established for the Sepang event will be reinstated for the Singapore Grand Prix should similar weather conditions be expected,” the FIA said. “Additionally, a further update to the wet weather software will be released for the United States Grand Prix.”
The FIA added that it, the teams and engine manufacturers “will continue to strengthen power unit software testing and verification capabilities, enhancing the overall validation process through independent assessment and collaborative feedback.”
Drivers were scathing of the software bugs last week in Malaysia. Hamilton likened driving the sluggish cars to gimmicky pre-race exhibitions the drivers have done previously and four-time champion Max Verstappen called for a “lesson learned.”
The FIA said it had conducted testing on the software which failed last week, but that took place in two practice sessions which were largely dry ahead of races in Belgium and the Netherlands.
