171 laps of the Catalunya Circuit totals 796 kilometres. That’s the distance Sebastian Vettel reeled off in the SF71H on this the first day of the second and final pre-season test session. This time, the weather behaved itself with air temperature reaching 15 degrees and the track hitting 26. Only wind in the afternoon affected the session.
Scuderia Ferrari set to work on the dot of 9, the car doing some laps fitted with sensors to acquire data linked to the aerodynamics. After that came some relatively long runs, switching between the Soft and Medium compound tyres. It was on the latter that Seb set his fastest time in 1’20”396, on his 66th lap.
“It was a good day’s work,” commented Seb at the end of the session. “We managed to get through our programme, even if the conditions weren’t always ideal, because of the wind.”
