For the second and final day of the first in-season test of the year, Carlos Sainz was behind the wheel of the STR10. After Pierre Gasly had racked up the miles yesterday, the Spaniard also had a lot of track time, going past the century mark, completing the second highest number of laps on the day. Now, there’s just time to assess the results of these two productive days in Barcelona, before heading off to Monaco, where track action for the most glamorous race on the Formula 1 calendar gets underway one week from tomorrow.
Phil Charles (Chief Race Engineer)
“We can ignore our lap times, because today was actually very good for us. We completed a lot of laps and apart from a few minor things, I can say we have ticked off all the boxes on our work sheet, provided by the factory and from what came out of our race debriefs. This morning we fitted the rake to the car to get some extra aero data and also did some brake work. Then we continued with our runs for more aero work, before finishing the morning with some set-up testing. After lunch, we concentrated on long run tyre evaluation and because that went well, we managed to fit in some more set-up work right at the end.”
Carlos Sainz (Car 55)
“The plan today was focussed mainly on long runs, trying to see what we could learn about the car with high fuel loads. That was the configuration which proved to be our main weakness over the Grand Prix weekend here at this circuit. We managed to do 126 laps, we learned a lot and now we have to make the most of that over the forthcoming races.”
