Formula 1 returns home to Europe, for the Spanish Grand Prix in Barcelona. The teams know this place well. During the winter, the circuit is very popular for testing. The reason: Spains mild climate! The 4.7 kilometres are a good mix of quick corners and tight turns, which are pretty demanding, especially on the brakes. For example, immediately going into turn 1, the best chance to overtake after 16 seconds flat out on the start/finish straight.
