FP1: Verstappen leads Bottas and Hamilton in opening Hungaroring practice session

Championship leader Max Verstappen set the fastest time in sweltering conditions in first practice for the Hungarian Grand Prix, ahead of Mercedes pair Valtteri Bottas and Lewis Hamilton. The session was briefly red-flagged for Yuki Tsunoda's Turn 4 crash with 18 minutes left.

Verstappen, running the Honda engine that sustained the 51G impact in his Lap 1 crash at the British Grand Prix, was fastest out of the gate with hard tyres at the Hungaroring and switched to softs after Tsunoda's red flag. He set the fastest time of 1m17.555s, clear by just 0.061s.
