Circuit de Barcelona-Catalunya

The Circuit de Barcelona-Catalunya has been the home of the Spanish Grand Prix since 1991 and serves as F1's primary testing venue. This 4.657-kilometer circuit near Barcelona features a challenging mix of high-speed and low-speed corners that provide an excellent barometer of car performance, making it invaluable for teams' development programs.

The track is notoriously difficult for overtaking due to its combination of fast corners that disturb aerodynamic performance when following closely. However, the long main straight into Turn 1 does offer opportunities, and the high-speed final sector punishes any car lacking downforce. The abrasive surface and hot Spanish sun create severe tire degradation.

Catalunya has produced legendary moments, including Michael Schumacher's first Ferrari victory in the rain in 1996 and Max Verstappen becoming the youngest ever Grand Prix winner in 2016 after the two Mercedes drivers collided on the opening lap.
