Mercedes Faces New F1 Threat From Upgraded McLaren

McLaren’s latest Formula 1 upgrade package has put the team in position to pressure championship leader Mercedes through the rest of the 2026 season, according to Formula 1 lead commentator David Croft.

CroSources said the step forward was clear around the Hungarian Grand Prix, where McLaren arrived aiming to cut the deficit to Mercedes after what was described as a demanding first half of the year. Lando Norris then secured his first grand prix win as the reigning champion.

Hungarian GP upgrade signals a pace shift

Speaking on the F1 Show, Croft credited McLaren for introducing updates that delivered “genuine pace” and, in his view, allowed the Woking team to turn the tables on its own power unit supplier. He said the team’s understanding of the power unit had improved significantly compared with the start of the year, noting that the season is now 11 races in.

Croft also pointed to recent form at the Hungaroring when weighing how surprising McLaren’s Hungary performance should be. He said McLaren had finished 1-2 in Budapest for the last two years, while adding that the strength Mercedes showed in Monaco made the scale of McLaren’s progress more notable.

He added that he did not consider Mercedes inherently weak at a circuit like Budapest, while acknowledging that Monaco’s outcome could have been influenced by driver-specific factors, including the weekend he described as exceptional for Kimi Antonelli.

Title picture: Norris faces a large points gap Norris sits fifth in the drivers’ standings with 128 points. He is 91 points behind championship leader Kimi Antonelli, the figures Croft discussed when assessing whether the championship battle can tighten.

Croft argued the deficit is not necessarily decisive, saying the drivers’ championship remains “very much up for grabs” and that Norris is not so far back that he cannot recover the gap. He framed the question as whether McLaren can sustain the momentum after the summer break.

Decisions after the summer break

Beyond outright pace, CroSources said McLaren will need to maximise every advantage and make clear choices on execution. One of the key questions he raised was whether the team will focus its efforts around Norris, and how that approach could intersect with a renewed push in the constructors’ championship.

While the upgrade has drawn praise, the durability of the progress remains uncertain. Croft’s comments highlighted that the competitive order can still vary by track and weekend, making McLaren’s ability to repeat its Hungary-level performance a central storyline for the remainder of 2026.
