Honda investigating Lance Stroll battery failures in Brazil

Honda chief engineer Shintaro Orihara has said the root cause of Lance Stroll's battery-related retirements at the Brazilian Grand Prix is not yet known. Stroll retired from the race after a battery issue, following a similar problem the day before, and the retirement was his 14th of the season.

Orihara said the team will check the data and the battery itself, and that it may take a few weeks to identify the cause. He stressed that counters must be found for next year to avoid the same issue recurring. Honda says the review could take around two weeks to complete, with the 2027 season a clear focus.

Honda CEO Toshihiro Mibe attended the race at Interlagos. Orihara said Mibe's presence trackside was a positive, as it would help the manufacturer's development in Japan. Aston Martin's Mike Krack also welcomed Honda executives at the event.
