Circuit de Catalunya Barcelona

The Circuit de Catalunya Barcelona is one of the more difficult race courses in the Formula One racing calendar.

The wind direction at the circuit can change drastically during the day, a significant factor given the importance of aerodynamics to modern Formula One cars. It is then hard to find a good setup since cars 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.
