An extra DRS zone has been added for the Australian Grand Prix this year.
A single DRS zone was used during last year’s race, the first in which DRS was used.
This year drivers will have the opportunity to use DRS twice per lap, as Sauber’s head of track engineering Giampaolo Dall’Ara explained:
“Historically overtaking has been difficult in Melbourne, but this time there will be two DRS zones.”
Kamui Kobayashi said the unusual nature of the Melbourne track may not give an accurate impression of how competitive the team is in the first race of the year.
“The Albert Park circuit itself has a very nice layout,” he said. “The fact it isn’t a permanent race track, and therefore very slippery at the beginning of the weekend, doesn’t make the set up work for the first Grand Prix any easier, but to adapt to the improving grip level is a challenge for everyone.”
