Norris demands McLaren investigation after battery failure ruins Monaco qualifying

Lando Norris will line up from the fourth row at the Monaco Grand Prix after a battery failure derailed his weekend, with the McLaren driver calling on his team to urgently investigate what went wrong following a difficult qualifying session at the Circuit de Monaco.

Norris, who won in Monaco last year, finished eighth in qualifying — a result compounded by the loss of track time in FP2 when his car suddenly shut down on circuit. The breakdown triggered a stewards’ inquiry into why marshals were unable to move the stricken car to safety, with a dolly ultimately required to tow it away.

In an attempt to resolve the issue before Saturday’s running, McLaren worked through the night and replaced the wiring harness, also changing the ESME pack within the permitted allocation. The team confirmed they breached the sport’s 10pm curfew in doing so, releasing a statement acknowledging the decision was made to “investigate and address the issue comprehensively.”

Speaking after qualifying, Norris was candid about the scale of the challenge ahead. “Tricky day. We’re clearly off the pace and need to find time all across the lap,” he said. “Frustrating to lose track time today, as that’s always important here in Monaco. The car simply turned off, so we need to investigate what happened there.”

Norris acknowledged that a repeat of his 2024 Monaco victory looks unlikely from his current grid position. “Realistically it’s going to be difficult to compete at the front of the field this weekend based on where we are compared to the competition,” he said. “It’s not necessarily a surprise, but it’s not where we want to be, so we’ll work hard to understand what we’re missing and try to recover where we can.”

The curfew breach adds a regulatory dimension to McLaren’s weekend troubles, with the team facing potential scrutiny from officials on top of the technical problems already under investigation.
