Nyck de Vries opened the Formula 2 weekend from the Hungaroring on top of the timesheets, laying down a 1:29.236.
The Dutchman is looking to extend his lead in the championship this weekend, as he currently holds a 31 lead over Nicholas Latifi, who failed to finish the practice session inside the top ten.
There was one red flag during the session as Ralph Boschung, who returns to the F1 feeder championship this weekend with Trident, crashed at Turn 1, appearing to lose the rear of the car as he lapped the circuit.
De Vries also had a spin during the session but managed to avoid making contact with the barrier.
