I think it is a blown wing.

I don't know if it can stall or turn off like an F-duct, but indications seem to say it is adding down-force to the wing.

As you know the main plain is blown by the slots on the pylons and endplates, the pylon slots shoot jets of area span-wise across the wing. The effect is a high velocity peak running across the underside of the wing in a V-shape.

I have not put in the slots in the end-plates though, those would make a very interesting shape as those air streams would interfere with the ones coming from the pylon.

It is very clever of Lotus to put the slots in the pylon and end-plates in a reaction to the ban on slotted rear wings.
Yeah but they could make bigger slots/slits in the RW then those on the pylon as we have said you can have slots in the middle 15cm.

here we go again, everything against lotus. first their ride-height device banned when was already devoloped with E20, then now when they created their own DDRS (after many protest about regulations) is also banned. same happend with their F-duct 2010. when they created their own F-duct, FIA banned them for next year :roll:

Lol ? If anything this hurts mercedes more cause they have had it from start, and in 2010 everyone had an F-duct except 3 backmarkers so it affected everyone the same.

i didnt make consumption who will this hurt more, ofc merc will be the one who will suffer the most. but mercedes like mclaren that year, they had it from the start they had advantage of her for whole season. lotus on other case spend money for something what will they throw aways for few races. and like I said same thing happend them for ride-height device, they spend money and time for devoloping sistem, even FIA gave them permission to be banned before first race. CONSPIRACY!

They never planned to race the ride height stuff, they have said that in an interview before the season, they just looked into it for the future 2013 and beyond, but it was banned before this season so ofc it was a setback but prob not for this car or any car infact.

They were quite aware that it would be banned right away (they know there is something about movable aero in the rulebook), but on the off-chance the FIA doesn't know that it can't hurt to ask.

Good riddance. And Lotus was probably against it as well, they rather hesitate to include complicated solutions that force them to rearrange the innards of a car after last year (they have no fancy EBD and the pylon system for the rear wing is very well contained in the rear engine cover).

The minute that the Merc DDRS system was cleared of illegality in China (I believe?) there was an expectation that, whilst the system would be allowed for this year as it doesn't contravene any rules so-to-speak, the loophole which allows it to be deemed legal would be closed for 2013. This is more of a confirmation of the expected result, not at all out of the blue!

As all the teams knew that the DDRS was likely to be outlawed for 2013 a lot of teams appear to have not bothered looking at introducing it due to the fact that the gains it seems to offer aren't massive (far from the silver bullet like the 'full' F-Ducts of 2010/2011 EBDs) and any money invested would effectively be thrown away at seasons end. Lotus had the option of developing it or leaving it alone knowing all this and went for it anyway so don't think for a minute that the FIA decided to make it illegal only after Lotus had developed their iteration of it.

Funny that Ross Brawn keeps telling it would only cost a few thousand pounds. He looks very eager to forget that for the same concept the W03 has, you would need to repackage the entire car, build a new chassis and of course make sure it does work. Him downplaying the costs makes me believe a DDRS brings more then just a tenth.

Well for next year if it wasnt banned ppl would add it, and its not like they would need to make big changes to their cars to incorporate it from start.

From the start probably not, although if it was allowed next year I could imagine several teams taking the idea to the extreme, shedding extra drag at the rear wing, front wing, diffuser and who knows at whichever place they could find. Implemented such a car wide system would cost huge sums.

I think it shouldnt have been banned, yet another innovation we can kiss goodbye to, I think its great to find these systems and try and find out how they work, what are the grounds on banning it because it cannot be cost as RB has already discussed, every great innovation gets banned.

F ducts, DDD's, DDRS, EBD's, I think its time they allowed a bit of innovation IMHO :D

There has to be sense in everything even cost cutting, i mean sure brawn says its cheap it might not be as cheap as he says but then again its not a DDD or an EBD which were immense things that meant you were behind if you didnt have them, this DDRS is far from giving an advantage to Merc or Lotus, so i dont get why ppl couldnt have had the opportunity to explore it alittle more.

Also for a team like Lotus if we for sake being say they win this years championship, that will prob mean that the extra cash from winning will outweigh the cost that it took to develop this DDRS for this year even if the DDRS just gave them 0.1, that was worth it.

Regardless of how it works, I think its a dual system, others think its purely passive, I dont believe it is in the interests of the sport to ban it, :)
