Day two at the Barcelona Circuit saw new Haas driver Kevin Magnussen behind the wheel where he had another productive outing with the Haas VF-17. After taking to the 4.655-kilometer 16 turn track as soon as it opened at 9 a.m. local time, Magnussen ended the test nine hours later with 118 laps on the board to total 549.29 kilometers (341.313 miles), the most of any driver.

The result more than doubled Magnussen's total from Monday when he ran 51 laps and it shattered Haas F1 Team's mileage total from any previous test at Barcelona. Prior to Tuesday, the most laps Haas F1 Team ran in a single-day test at Barcelona was 105 on May 18, 2016.

In addition to logging the most laps, Magnussen remained fast. He set the fourth-quickest time with a 1:22.204 on his 103rd lap shod on a set of Pirelli P Zero Red supersoft tires.

He began the morning session with a series of reconnaissance laps, first using the Orange hard tire before optioning between the White medium tire and the Yellow soft. After five laps of systems checks, it was time for some outright running, first with White mediums and then on Yellow softs. As the clock ticked closer to the mandatory lunch break, Magnussen's times ticked downward too. His best time in the morning was a 1:23.200, secured with Yellow softs on his 36th and final lap of the session to put him fourth overall.

The afternoon segment saw Haas F1 Team sample nearly all of the tires in Pirelli's lineup with the Orange hard, White medium, Yellow soft and Red supersoft each getting a workout. Magnussen made the most of the day's second half, knocking out 82 laps. The team practiced their pit stops, bolting on four new fresh tires to the Haas VF-17, and sending Magnussen back onto the track. The Red supersofts provided the most grip, and Magnussen unsurprisingly knocked down his quickest time in the day's final 30 minutes.

“A good day. I got the most laps of anyone, so that's sums up our day pretty well, with lots of running,” said Kevin. “That's what it's all about here at winter testing. We want to put as many miles on the car as possible, to find all of these little problems that can creep up during the season, to catch them as early as possible. I'm very happy with the feeling I have in the car and in working with the team. It's been good to get back in a car again.”

Teammate Romain Grosjean takes over the Haas VF-17 for the remaining two days to finish out the first week of testing. Then, after a four-day break, teams return to Barcelona for the second and final round of preseason testing March 7-10. Magnussen drives March 7 and March 9, and Grosjean drives March 8 and March 10.
