The FIA has confirmed that significant changes will be made to the Drag Reduction System at five Formula 1 tracks.
The governing body analysed DRS at various tracks and has made changes that will either facilitate overtaking, or make it harder at a circuit where it was deemed not enough of a challenge.
These changes will be implemented at Bahrain, Jeddah, Melbourne, Baku and Miami, and involved the adjustment of the detection and activation zones.
For the upcoming Australian Grand Prix at Melbourne the fourth DRS zone will be reinstated, after previously being taken away last year on safety grounds.
