Norris Edges Antonelli by a Thousandth in Mexico City Practice

Lando Norris had the quickest time in final practice for the Mexico City Grand Prix, finishing 0.001 seconds ahead of Mercedes' Kimi Antonelli. A margin that small is effectively a tie, and it leaves the front of the order wide open going into qualifying.

Practice times are a rehearsal rather than a result, and a gap of a thousandth of a second is far smaller than anything a driver can feel from the cockpit. Still, the timesheet tells teams where their set-up stands and shows which cars are finding pace on the Hermanos Rodriguez circuit. McLaren heads into qualifying holding the top spot, and Mercedes can take encouragement from how close Antonelli came.

Qualifying will decide the grid, and with the top two separated by almost nothing, a small error, a traffic problem or a tyre that is not quite in its window could change the outcome. Mexico City's high altitude adds another variable, since the thinner air affects engine output and braking, so the two teams will be working to get the most out of their cars under unusual conditions.
