This is actually turned out to be pretty tricky. Startfinish straight isn’t long enough to gain full DRS effect, so we have only one alternative which is back straight with a fast kink in the middle of it. In my view, to make DRS really work for the driver it should be detected on the exitentry of a slow chicane before back straight and activated right before the kink of turn 11 and going on until braking for turn 12. If they’ll all be safe through the kink with their wings open the it will be fine. Otherwise i think they’ll move the zone to startfinish straight for safety reasons since it is longer than the backstraight pre & post turn 11 parts.
Spain: Pit straight. Right before braking into Elf & Renault. It could be a nice option placing it before hairpin of La Caixa, but i don’t think it will work well, because we got Campsa before it – an ultra-fast right hander. Look for Melbourne DRS zone right on the out of fast corner to see how well it works. No really well, isn’t it.
Monaco: Should be in tunnel, but the kink in the tunnel is not that easy at all, i think safety will come into play here as in Turkey as well. But where are the alternatives? I don’t believe in a DRS zone between Anthony Noghes and St.Devote, at all. On the other hand, zone from St.Devote up through Beau Rivage and into Massenet and Casino looks like fun with some options in terms of racing line. Although very easy to defend still. This is one of the circuits where FIA will consider is it necessary at all to have a DRS zone in the race.
Canada: Back straight between hairpin and chicane, as many said. No doubts here. Plenty of room for detection line and activation zone itself. Could be real fun into last corner.
Valencia: Straight after bridge and turn 10, detection is straight on the exit of 10 or in the middle of the bridge before it. But in the interest of spectators they might use pit straight, right from last turn. Turn one shouldn’t be a problem with wing open, but you never know.
UK: Hangar straight, Wellington straight does not looks credible for the job – it is shorter, and opens with a slow speed turn. Passing move assisted by drag reduction doesn’t seem realistic. It is the new pits the year, by the way! First lap madness at the Arena and diving into the pits straight after the Stowe sounding like fun!
Germany: My guess is they’ll use it either before the chicane at the end of the lap or put in before turn one. The latter seems more realistic, because of solid straight length, slow turns before and after and lots of grandstands around.
Hungary: Pit straight zone, no options.
Belgium: Kemmel straight seems like it, with detection line into Eau Rouge. It could be neat to have a zone before Bus Stop, but Blanchimont can be tricky with race fuel and wing opened and it is bloody fast without lots of runoff. Safety first!
Italy: This track is one big DRS zone! I think, given that there’s no more F-Duct this season, FIA will look closely whether it is really necessary to use DRS in Monza at all. If it will be used, it is going to be pit straight, for many many reasons.
Singapore: Straight before Turn 7, the only place when you really have a chance to pull DRS-assisted move.
Japan: This is a tricky one, isn’t it? My guess it will be pit straight. Back straight looks less likely simply because of a fast exit out of Spoon and completely flat out 130R – there will be no brakes applied to automatically shut down the wing and i think nobody wants to see a car spinning out of control at around 300 kmh. To add even more question marks to the puzzle, the entry of turn one is really late and almost flat as well. But with the fuel on i think there will be a bit of braking into turn one for most of the race.
Korea: Back straight, nice and simple. Detect into turns one and two, open up before braking at turn 3.
India: No real guess, but back straight looks like a solid host to DRS zone.
Abu Dhabi: They are going to make changes to the layout this year, aren’t they? If not, straight after turn 7 hairpin is the way to go in my opinion.
Brazil: Start finish straight, i’m pretty sure about that. Detection at the exit of Juncao, activation after Subida Dos Boxes. Back straight after never ending Curva Do Sol doesn’t looks like a healthy option, to be honest.
