Haas F1 Team driver Romain Grosjean had a methodical day of testing Wednesday at Circuit de Barcelona – Catalunya, amassing 96 laps round the 4.655-kilometer (2.892-mile), 16-turn track.

Grosjean systematically worked through a variety of baseline setup configurations on the Haas VF-17 throughout the morning before experimenting with the full range of Pirelli’s tire compounds in the afternoon.
Grosjean’s quickest time was a 1:21.887, earned on his 66th lap while utilizing a set of Pirelli P Zero Purple ultrasoft tires. It placed him 10th among the 14 drivers who took to the racetrack.
The morning session mirrored the schedule teammate Kevin Magnussen followed Tuesday – a series of early laps on the White medium tire after an installation tour on the Orange hard option, followed by a switch to the Yellow soft compound to exploit its increased grip. Grosjean’s best time in the morning was a 1:22.428, secured on his 36th lap. He tallied 54 laps before the mandatory lunch break.
Haas F1 Team ceded 90 minutes of run time in the afternoon to fix an exhaust issue. The shortened run plan meant valuable race simulation laps were condensed following double stints trialing the Red supersoft and Purple ultrasoft tires, the latter of which Grosjean used to secure his fastest lap. There were two red-flag stoppages in the day’s closing minutes, denying Grosjean the opportunity to surpass 100 laps.
Mercedes’ Valtteri Bottas set the quickest time (1:19.310) and Red Bull Racing’s Max Verstappen ran the most laps (102).
