Both novelties are to enhance overtaking opportunities for the 22 drivers in the field and to allow for more variety in the race strategy. Further changes in the regulations: in the fourth and final qualifying heat, the use of fresh tires is now allowed. Moreover, teams have to determine and announce the tires for the start of the race after qualifying.
In the race, the time window for the two mandatory pit stops has been abandoned. Only in the first three laps and the three final laps of the race, no car is allowed to enter the pits for the mandatory tire changes
