Formula 1 has confirmed details of the three DRS zones which will be used for this weekend’s inaugural Miami Grand Prix.
Each zone on the 5.4-kilometre Miami International Autodrome will have its own detection point.
Two of the zones are situated on long, high-speed sections, though drivers will not be able to use DRS for the first few hundred metres of each..
The first detection points is shortly after turn eight, though drivers cannot activate DRS until 67 metres after turn nine. This forms part of a long, high-speed section through turn 10, leading to a potential overtaking spot at turn 11.
The second DRS detection points follows at the end of sector two, 73 metres after turn 16 where a tight, straight section begins. Again, drivers cannot activate DRS until 450 metres after that corner.
The final detection zone is at the opposite end of that straight, 19 metres after turn 17, a sharp left-hand hairpin. Drivers can then open DRS at the apex of turn 19 at the end of the lap.
Three DRS zones has been typical of the venues F1 has visited so far this season. Only one track, Imola, had fewer. Albert Park initially boasted four, but that was cut to three following the first day of running.
The speed trap for Miami International Autodrome has been places 200m before turn 17, at the end of the long back straight and in theory when drivers should be at absolute maximum speed, despite the proximity of the walls.
