Zak Brown reveals overnight rebuild after Norris issue as McLaren targets Monaco surprise
McLaren’s mechanics endured a long night in Monaco after the mysterious technical problem that prematurely ended Lando Norris’ Friday running, with CEO Zak Brown admitting the team is still searching for a definitive explanation.
The reigning World Champion’s second practice session came to an abrupt halt when his car suddenly lost power, forcing him to stop on track and depriving him of valuable mileage around one of the most demanding circuits on the Formula 1 calendar.
With qualifying often deciding the outcome of the Monaco Grand Prix, every lap matters. That made Friday’s interruption particularly frustrating for Norris and the McLaren engineers, who were left with limited time to identify the source of the problem before Saturday’s crucial sessions.
McLaren replaced components as a precaution
Speaking to Sky Sports F1, Zak Brown revealed that the team was unable to conclusively determine the exact cause of the failure, prompting McLaren to take an aggressive approach overnight: “It wasn’t positive what the final issue was on Lando’s car – was it battery or electric related. So we decided to change everything as a precaution.”
The uncertainty surrounding the fault highlights just how difficult modern Formula 1 systems can be to diagnose, particularly when electrical and hybrid components are involved. Rather than risk a repeat failure during qualifying, McLaren opted to replace multiple parts in an effort to eliminate any potential weaknesses.
Brown also praised the effort of the team members, who remained at the circuit until the early hours of the morning: “The team was here until about 3am but it looks like we are making some improvements today.”
That overnight work could prove vital. Monaco rewards confidence and rhythm more than almost any other track, and ensuring Norris has a fully reliable car underneath him is the first step toward extracting maximum performance.
McLaren realistic about qualifying expectations
Despite signs of progress, Brown remains cautious when assessing where McLaren fits into the competitive order heading into qualifying.
While the Woking-based team has introduced circuit-specific updates for Monaco and continues to search for improvements in tyre preparation and mechanical balance, Brown acknowledged that the leading teams still appear to have an advantage.
Asked whether McLaren could secure a place on the second row of the grid, he offered a measured response: “I’d like to say yes but I think that’s me being a bit optimistic. Mercedes, Ferrari and Max… I think third row unless someone makes a mistake which unfortunately in Formula 1 they don’t do very often.”
The comment reflects the current reality at the front of the field. Ferrari has shown impressive pace throughout the Monaco weekend, Mercedes remains a benchmark in qualifying trim, and Max Verstappen continues to extract exceptional performance from his Red Bull in decisive moments. Even so, Brown stopped short of ruling out a stronger result.
“Second row wouldn’t shock me but I might be in the optimistic side.”
Qualifying remains the key opportunity
With overtaking notoriously difficult around the narrow streets of Monte Carlo, qualifying is likely to determine the shape of McLaren’s weekend. If the overnight changes have resolved Norris’ reliability concerns and the team can unlock a few more tenths of performance, a place near the front of the grid remains achievable.
Whether that translates into a second-row start or a battle for the third row will depend on execution, traffic management and the team’s ability to maximise every opportunity during a session where margins are expected to be incredibly small.
For now, McLaren can at least take some comfort from the fact that Norris is back on track. The mystery surrounding Friday’s failure may not be fully solved, but the team’s response has ensured it enters qualifying with renewed confidence and a car prepared for one of the most important sessions of the season.
