Photo overview | F1 teams experience useful second day in Barcelona

The Formula 1 teams were again busy improving their cars on the second day of testing in Barcelona. Where Mercedes and Red Bull Racing had to solve problems, Ferrari and McLaren again made a good impression.

It is not easy for the teams to get a strong car onto the track this season. Because of the new regulations they have to tinker with the new cars and they encounter problems they didn't encounter before. Lewis Hamilton and Sergio Perez, for example, had some problems with their cars.

Nevertheless, all teams made ample use of the day again on Thursday to carry out various tests to prepare for the new season. Besides the data collected by the teams, the laps made by the drivers provided some great images. We put a number of photos in a row.
