For the first time since its introduction in 2011 in the Formula 1 World Championship, the DRS will be the subject of four dedicated zones at Melbourne Park, on the occasion of the Australian Grand Prix next Sunday. Mounted on the rear wing of the single-seaters, this opening device, authorized only in certain sections of the circuit, allows the single-seaters to reduce their drag, which facilitates overtaking in the race. They were until then two or three in number per Grand Prix.
