Lewis Hamilton’s dream of claiming a record-breaking eighth Formula 1 world championship has been dealt a significant blow by his former team.
The 2026 season has set up one of the most intriguing title battles in recent memory, with Hamilton pitted directly against the Silver Arrows in the standings.
Mercedes currently hold the upper hand in power unit performance, sitting top of the class in that regard regardless of the ADUO ruling’s implications.
Ferrari, however, have been widely regarded as the superior package when it comes to the car’s chassis, keeping Hamilton and the Scuderia firmly in championship contention.
The key vulnerability for Mercedes throughout the season has been reliability, with both George Russell and Kimi Antonelli suffering damaging DNFs at crucial moments.
That weakness now appears to be closing, with Toto Wolff’s team identifying the root cause of the terminal failures that have affected their cars this season.
Technical director James Allison addressed the issue openly on the team’s Nu Silver Arrows Radio Show, expressing cautious confidence that the problems are now understood.
“I think anyone who’s a keen watcher of the sport will have seen that this has laid a few Mercedes engine cars low over the season so far,” Allison said.
He added: “They’re not all identical, but they do sort of originate in the same broad part of the battery, and I think that most of the areas of risk have been understood.”
Allison explained that the team refers to the battery as the “module” and indicated that phasing in new modules during the racing season should help improve reliability across the fleet.
“Obviously for us, that’s an important thing. These DNFs are very, very painful,” the technical director confirmed.
In the drivers’ championship, Antonelli leads the way on 156 points, with Hamilton second on 115 and Russell third on 106, meaning the gaps remain very much closeable.
In the constructors’ standings, Mercedes hold a 72-point advantage over Ferrari, a buffer that could grow considerably if the battery issues are truly resolved.
The next opportunity for both teams to make their mark comes at the Austrian Grand Prix, scheduled for June 26 to 28.
