Formula 1's ruling body, the FIA, has added a third DRS zone to the Marina Bay circuit for this weekend's Singapore Grand Prix.
In an attempt to boost overtaking at the street circuit, a new DRS zone has been added between Turns 13 and 14.
The detection zone will be placed 102 meters before Turn 13.
The other two DRS zones, which were already in place in previous races at Marina Bay, are located on the pit straight and between Turns 5 and 7.
Drivers are allowed to use the DRS freely during practice and qualifying in the designated zones and when they are running within one second of the car ahead in the race.
