Lando Norris led the way in the opening Formula 1 practice session of the 2025 Spanish Grand Prix at Barcelona.
There was no early evidence of McLaren having its form upended by the much-anticipated changes to the FIA's flexi-wing compliance testing, with Norris quickest both in his initial run on the hard tyre and the first push laps on the soft.
Though he may have been ever-so-slightly aided by logging his lap marginally later than his main rivals, Norris ended up comfortably clear with his 1m13.718s effort - 0.367 seconds up on the Red Bull of Max Verstappen.
Norris's championship-leading team-mate Oscar Piastri was off his team-mate's pace both on the hard and on the soft, which in the end left him six tenths off - beaten also by the Ferraris of Lewis Hamilton and Charles Leclerc.
The Mercedes cars were absent from the top half of the classification - but they logged their fastest laps early and did so on the medium tyre instead of the soft, George Russell in 11th with six tenths in hand over rookie team-mate Kimi Antonelli down in 18th.
Of the 'midfield' squads, Racing Bulls stood out with Liam Lawson in sixth, the Kiwi two and a half tenths up on Haas driver Ollie Bearman.
It was an incident-free hour of running, the only real moment of note coming when Haas' FP1-only driver Ryo Hirakawa went into the gravel trap at Turn 10.
Le Mans 24 Hours winner Hirakawa, driving for Haas in relief of Esteban Ocon as part of the team's Toyota tie-in, bounced back from that to place 17th, seven tenths off Bearman on the same tyre.
The other FP1-only driver, new-for-2025 Williams junior Victor Martins, was 19th, six tenths back from Carlos Sainz in Alex Albon's car - with both drivers doing their second runs on mediums.
