The Circuit de Barcelona-Catalunya is a 4.655 km circuit in Montmeló, Catalonia, Spain. With long straights and a variety of corners, the Circuit de Barcelona-Catalunya is seen as an all-rounder circuit. The wind direction at the circuit can change drastically during the day, a significant factor given the importance of aerodynamics. It makes the setup of the cars crucial as it can have massive aerodynamic drag and understeer on one part of the circuit in the morning, but suffer oversteer at the same part of the circuit in the afternoon! These changeable conditions can make for unexpected performances from some teams during the race.
