Ferrari looked in good shape, as might have been expected on a track that lends itself to the car’s strong cornering performance.
But Mercedes, with George Russell in fifth 0.933secs off the pace and championship leader Kimi Antonelli in 13th, appeared to have some work to do.
Antonelli did not complete a qualifying simulation lap in the second session.
His first had to be abandoned when Franco Colapinto crashed his Alpine at the last corner, and his second came to grief when he made an error going into the chicane.
Antonelli was complaining all session about rear brake locking, but he was on a par with Norris’ time in the first sector on both laps before they were curtailed.
Behind Russell, Red Bull’s Isack Hadjar was sixth fastest, ahead of Racing Bulls’ Liam Lawson and McLaren’s Oscar Piastri.
Audi’s Nico Hulkenberg and Racing Bulls’ Arvid Lindblad completed the top 10.
