Carlos Sainz set seventh fastest in fifth day of Barcelona pre-season test and he is only made a red flag in the early afternoon. Significantly modified Toro Rosso successively made 85 laps without any trouble. They are adapted short-nose like Williams F1, and tighten the rear of STR-10.
Following the test Sainz say that he felt great improvement specially grip and balance.
“It was very nice to drive the car fitted with the update package. That meant much of my time was spent collecting valuable aero data for the engineers to study. Then towards the end of the morning, I managed to do a real run.” He told official team website.
“I could immediately feel an improvement in the car, in terms of its overall grip and balance. That was a very positive and motivating feeling for the rest of the day. We did have an issue that cost us some track time in the afternoon, but the guys did a great job to fix it and get me out on track again, with enough time to do two more useful runs before the chequered flag.”
Phil Charles (Chief Race Engineer) – “As planned, we had various updates, as part of a new package, to try for the first time and so the bulk of the day was given over to aero and other measurements. It all went well, although we did lose some time in the middle of the day.”
“Generally, the new parts produced encouraging results. In the afternoon, apart from a couple of aero tests, we also did some mechanical work. Carlos did a good job, running Hard and Medium Pirellis throughout the day.”
