The Formula One and GP3 teams are no strangers to the Circuit de Barcelona-Catalunya (formerly known as the Circuit de Catalunya); not only have they raced there every year since 1991, they also conduct extensive testing at the venue.
Familiarity does not, however, lessen the challenge for car or driver. Barcelona's mix of high- and low-speed corners, plus its abrasive and rather bumpy track surface, makes for a physically and mechanically taxing race.
Tyre wear is particularly high and the varying winds that cut across the circuit mean an optimum set-up can be hard to find. For spectators Turn 1 (also known as Elf corner) is among the best places to watch, as it is one of the track's few overtaking opportunities.
For the drivers it is the final two turns, known collectively as New Holland, which provide one of the biggest challenges of the season. A fast exit is essential in order to maximise speed down the start-finish straight into Elf.
