Martin Brundle's worrying Aston Martin verdict raises more questions for Lawrence Stroll

It's not a great time to be the F1 team running Honda power units, as Aston Martin are continuing to learn.

Lawrence Stroll's team have had disastrous reliability issues throughout the 2026 season, often linked to their power units, while their straight line speed has also been down on their competitors.

The team owner's son Lance Stroll retired from the Brazilian Grand Prix last Sunday with what Honda characterised as an ERS issue in the power unit, his 13th retirement of the season and the 14th time he failed to complete enough laps to be a classified finisher.

Sky Sports commentator Martin Brundle revealed that the older Stroll is 'at his wit's end' about the continued power unit struggles, with new reliability issues popping up on what feels like a weekly basis.

Aston Martin owner 'doesn't know what to do' about Honda issues

The long-time commentator and former driver said: “We were talking to Lawrence Stroll, the boss, about it. He’s at his wit’s end. He doesn’t know what to do about these endless reliability issues and non-finishes in the team.

“What are they going to do for next year? Have they got different ideas, different people to sort the problem out? The battery pack, the ERS, the energy recovery system and just the power deficit they’ve got.

“That’s the problem Aston Martin have at the moment: Where do they go from here?”

Honda boss: We need to find root of Stroll issue

After the power unit failure at Interlagos, Honda's Shintaro Orihara said that the power unit supplier are aware of what the problem was on the Canadian's car, but not the root cause of the issue - with a thorough investigation set to take place before the next race in Las Vegas.

“The race began well from a power unit perspective until we suffered an ERS issue on Lance’s car on Lap 30," he said after the race.

"From the data, we suspect it’s the same problem as yesterday and we need to find the root cause of this before the next race.

“Fernando’s eighth place on the grid is our highest starting position of the year with Aston Martin and that is encouraging. In the mixed weather conditions during the race, we kept adapting the power unit settings well to the wet and the dry running.

“The overall result today is better considering the tough outcome we had at the last event. The work will now continue in the UK and Japan to prepare for Las Vegas Grand Prix.”
