Vowles: Sainz's comments have helped us already

      When drivers change teams, but have the opportunity to participate in post-season tests, teams usually use these tests to tune the seat, steering wheel and pedals so as not to waste precious time on them in pre-season testing. In the case of Williams, things are a little different. Carlos Sainz's comments on the results of tests last December were taken into account, the team will put the finalized parts already in the pre-season tests. James Vowles, team manager: "In the first tests Carlos immediately demonstrated the highest professionalism, from the beginning acted clearly, providing us with accurate feedback and giving us the direction in which we need to add. Carlos was focused on using the data to make decisions. He made a few changes throughout the day and the lap times spoke for themselves. We have already incorporated his feedback into the design of the car. Normally it's quite difficult to do that, but Carlos' advice has helped us a lot."
