Preparing for an F1 race is a team effort, involving many departments and a variety of different roles. A lot of work takes place in the factory to enable the race team to hit the ground running at the track, and for the drivers to be in the best position possible on Friday for FP1.
Every track is different with its own unique characteristics. The main differentiator between the tracks is the layout, so the balance between corners and straights, and the corner types. But characteristics also refer to the tarmac, the weather, the kerbs, the run-off areas. All of these things are factored into setting up the car and how the drivers tackle a lap.
