Circuit de Barcelona-Catalunya officials have announced they will be the sole hosts of the two pre-season tests scheduled before the start of the 2016 Formula One season.
The tests will be divided into two four-day sessions, the first will run from February 22-25 and the second from March 1-4.
They also announced that all 2016 Spanish Grand Prix ticket holders will be able to attend the eight days of testing for free.

These dates have been brought forward following the alterations in the F1 calendar.
The changes have seen the season-opening Australian Grand Prix scheduled for March 20 instead of the more traditional April 3 slot. The tests were originally scheduled to run from March 1-4 and March 15-18, but the dates mentioned above have now been finalised.
Some team principles recently claimed that starting the season earlier will make life really tough for all of the teams, with Red Bull on the brink of being able to make the first test following uncertainty around its power supply.
Despite the various complaints, these tests actually give the teams an extra month to get the cars prepared and requires less travel compared to the 2015 pre-season tests.
This year's pre-season started on February 1 in Jerez which ran for four days, the teams then had to travel back to their respective main bases before travelling to the Circuit de Barcelona-Catalunya for four days of testing between February 19-22 and then a third test from February 26 to March 1.
These dates meant some teams were not ready in time for the first test with Force India, Sauber and Red Bull all failing to have their full specification cars ready.
With the extra month of preparation the teams now have for the 2016 season, we should see almost all teams arrive in Spain fully prepared.
