The 19th round of the 2019 FIA Formula One World Championship began with practice Friday at Circuit of the Americas as teams prepared for Sunday’s United States Grand Prix.
Two 90-minute sessions – FP1 and FP2 – on the 5.513-kilometer (3.426-mile), 20-turn circuit ran under mainly clear but cool conditions.
With air temperature hovering at just 8.6 degrees Celsius (47.48 degrees Fahrenheit) and track temperature at 14.1 degrees Celsius (57.38 degrees Fahrenheit) it was a frigid start to track activities in the morning. Both Haas F1 drivers started proceedings turning laps on the Pirelli P Zero Yellow medium tires before trialling two new sets each of Pirelli’s 2020 prototype Red soft rubber. Their final runs, now utilizing the standard soft compound, netted both Grosjean and Magnussen their quickest laps of the session. Grosjean posted a 1:35.356 for sixth fastest while Magnussen clocked a 1:35.659 to take 10th overall.
FP2 brought a slightly milder climate with air temperature climbing to 15.6 degrees Celsius (60.08 degrees Fahrenheit) and track temperature topping 24.9 degrees Celsius (76.82 degrees Fahrenheit). Unfortunately for Grosjean, his afternoon run-plan was brought to an abrupt halt with only four laps complete. Running off track and into the barriers while negotiating turns five and six ended the Frenchman’s session and brought the day’s solitary red flag stoppage. He had banked a 1:35.780 on a set of medium tires before the contact – placing him 18th overall. Magnussen started off on the White hard tire before switching to a set of Red softs. He logged his best time of 1:35.422 on a qualifying simulation, 17th fastest on the timesheet at the checkered.
Between the two sessions, Haas F1 Team ran a total of 79 laps – 51 by Magnussen and 28 by Grosjean.
