World champion Max Verstappen posted the fastest time Thursday on the first day of Formula 1 preseason testing in Bahrain.

The Red Bull driver posted his fastest lap of 1:32.837, 0.029 seconds quicker than Aston Martin’s Fernando Alonso, who posted 60 laps.

Verstappen completed 157 laps in the team’s new RB19, the only driver to take every lap Thursday.

“It’s a bit of an evolution from last year,” Verstappen said of the car afterward. “I think last year was more a time where you were really adapting to the car, really understanding what you had to do.

Ferrari’s Carlos Sainz and Charles Leclerc were third and fourth fastest on Thursday, the first of three days of testing at the Bahrain International Circuit. Nineteen drivers in all took test runs Thursday.

F1’s opening race is next weekend at Bahrain.

Verstappen will split time Friday with teammate Sergio Perez, who then gets an entire day driving Saturday.
