The FIA’s Charlie Whiting has confirmed that there will be two DRS zones at each race – if the circuit layout allows it – starting from Montreal.
The two zones will have to be consecutive, as the wing will be activated at the same point.
In Montreal they will be the last straight and the pit straight.
Whiting said the software that allows the use of two zones first became available for Turkey, but it wasn’t yet proven.
“We only had the software available in Turkey,” he said. “I thought it was too new and I wanted to make sure there were no bugs in it. We didn’t think there was anywhere suitable here, because they have to be consecutive straights, ideally, because it becomes more complicated the further apart they are.
“The first realistic opportunity we felt was Montreal. And in Valencia as currently planned it will be between Turns 10 and 12, and again between 14 and 17.”
