The battery enigma looms over Mercedes' leading campaign.

      Mercedes might be hiding a potential flaw beneath their strong start to the 2026 season. George Russell’s retirement while leading in Canada was due to a battery malfunction, and the team remains uncertain about the specifics of the failure. An Austrian newspaper, Osterreich, reported that the damaged battery was so extensively compromised that it couldn’t be flown back to Europe for examination. Consequently, it is being shipped by sea across the Atlantic for safety reasons. "The battery in Canada was a complete loss," stated the article. "Air transport was deemed too hazardous." This means that Mercedes engineers are faced with a frustrating delay before they can conduct a thorough forensic investigation. "The engineers responsible will have to wait before they can begin looking into the cause," the newspaper noted.

      The faulty component has been replaced for the Monaco race, but concerns heightened on Friday when Lando Norris, a McLaren driver powered by Mercedes, halted on track during the second practice session due to what appeared to be an electrical issue. Italian publication La Gazzetta dello Sport suggested the problem was battery-related, although McLaren's chief designer Rob Marshall stopped short of confirming that. "It could be anything, but it’s electrical," he remarked. The stoppage also led to a 30,000 euro fine after marshals were unable to shift the car into neutral. According to the stewards, "The team admitted that it had placed transparent tape over the button that needs to be pressed to activate the CDS for aerodynamic reasons."

      This incident coincided with McLaren's celebration of its 1000th grand prix in Monaco, although the team acknowledged some creative accounting. "No, we haven’t forgotten how to count," spokesperson Luca Colajani told Bild. "This statistic, stating that we’re racing our 999th event, includes the Indianapolis GP (of 2005). We counted that one even though we only completed the formation lap."

      While McLaren and Mercedes seek solutions, Ferrari has emerged as the frontrunner in Monaco. George Russell remarked that the Scuderia’s speed was anticipated. "Many believed we were just talking, but clearly not," he said. Russell acknowledged that Max Verstappen’s performance had also surprised Mercedes. "Red Bull was a shock for us," he explained. "We knew this track would be challenging, perhaps more so than we had expected."

      At the same time, Mercedes team principal Toto Wolff asserts that the championship contest between runaway leader Kimi Antonelli and Russell is currently free from team orders. "We will avoid team orders for as long as possible - and if feasible, not at all," he told Bild. "We don’t think we need them, and we allow the drivers to race." He admitted that the two drivers nearly crossed boundaries in Canada. "In Canada, they almost went too far, but we clarified that in a discussion," the Austrian shared. "Kimi and George understand their responsibilities to Mercedes." "Naturally, drivers prefer to win the Drivers’ World Championship over the Constructors’, but the team must come first."
