F1 Brazil GP live commentary and updates – sprint qualifying

Norris purple in sector one on his first flying lap. This is looking good so far as the timesheet is concerned but the in-car footage is revealing some gruesome understeer.

1m10.311s for Norris – but Piastri is faster with 1m10.286s.

Yuki Tsunoda first out of the garages and taking his place at the head of the queue to exit the pits when the lights go green. Remember SQ1 is just 12 minutes long so this will be fast – and some people will come out furious.

And as the engines fire up, the sun is still shining. Track temperature is 43C and ambient is 19C.
