Team also hoping for Grosjean with open "eyes" and functioning "brain" this weekend.


Like this?? :drunk: :drunk: :drunk:

Reports on the DRD definitely a part of Silverstone plans..

Scarbsf1 Tweeting the same...i just dont know personally..its just too good to be true.

Kravitz mentioned it as well, on the Sky F1 show, and Kimi told Lazenby that he'd had "small talks" with Red Bull.

It seems to have been engulfed in the Webber retirement/RB vacancy news flood..

Which is a shame cuz this is supposed to be a 'major' development...If it is tried and it works out as proposed,the 2nd half of the season would become a completely different ball game altogether.

Not for this race, in Silverstone the speed difference between the longest straight top speed and fastest corner is quite small. But if they can make it work from now on, that´s really good.

Its important even at Silverstone...The difference would still be significant because the device also supposedly increases rear downforce levels by anti-stalling the wing and increasing flow towards diffuser when cornering..

1.Silverstone is a high aero-df track..any addition in overall levels will help.

2.More downforce means improvement in tire heating issues,something that is the Achilles heels of the Lotus E21 when it comes to Quali..

3.More straight line acceleration with the Wing staller open..Lotus at the moment is very poor when it comes to overtaking on the straights..That will help.

All of this ofcourse depends on whether device works as planned..and obviously if Lotus decides to use it in Silverstone in the first place.

Of course it's on Kimi's car (could be on Romain's too) because he has tested the system before not Romain.

Even putting that aside,it makes sense to test it on KR......going by recent form ,means ending up 5th or 6th and that isnt going to do crap.

We need a win..taking the all or none approach is the way to go.

Didn´t know about that extra DF property, I thought it only took away drag at high speed.

If it does that, sure your number 1 and 2 pros are indeed worth, about 3, the advantage will be marginal. It will only cut drag down over the highest apex speed. And T1 is REALLY fast. That thing would only help in the very last part of the two longer straights, and only in laps where DRS is not avaliable.

Yes,it does do that,reportedly...See Scarbs and F1.com's explanation of the system from last year.Its still conjecture to some degree but thats the best we have.

About point 3,well thats not correct..The lotus device can be set to stall at any given speed limit ,even at one below the highest speed value through a fast corner.because at those high speeds(Scarborough suspects anything above 250 km/hr) the downforce is majorly provided by the diffuser which is enough for the aero load,the rear wing itself is not needed.


At Silverstone T6 is taken at 280 Km/hr,Turn 7 at 303 Km/hr and T1 at 302 Km/hr..The Lotus device's Stalling component can hypothetically work at all these 3 corners as soon as the car exceeds a speed roughly around 250 km/hr

To understand the device,here is Scarbsf1's Article..you can find more info from various other sources on Google.

It's not the only update the car has and not maybe even the most important one...the device is worth to 0,1-0,2 depending on track. New suspension and bodywork could be even more important ones.

Wasn't there a talk that DDRS is woth something like half a second when it was first introduced? Really that much of fuss for an update of 0.1 is rather silly, I guess.

it was said to be worth up to 0.5sec depending on the track. on fast tracks like Spa and Silverstone you could get as m uch as the mentioned 0.5

nope team denied the half second story written by autosport and told it's worth 0,1-0,2 at track like spa. Ideally it could be 0,5 but it takes away performance from other areas, that's why they haven't got it working so in the end the advantage could be a tehth or few but as long as it's step forward, everything goes.

I think that they're downplaying the device intentionally because of the competiton. If not, it's such a waste of time and money combined.

Source? I think 0,1-0,2 is total BS.

maybe but other teams has also studied it and said the advantage isn't that big in the end as it cost perfomance on other areas. 0,1 second in f1 is a lot of time.

It's not a lot of time if you develop it almost 2 years.

I think they were refering to the previous solution of their DRS. And that's why they were not using it at all.

At this point the resources have been spent so might as well take advantage of it. You live and learn etc. Also it'll pay dividends if they can now successfully implement it in future cars while other teams will have to waste resources figuring it out or miss the gains it brings.

My swing-o-meter has jumped back to insane unfounded optimism so waiting for Lotus to do their thing and **** everything up again. My body is ready.

Johnny Herbert on Sky, "The feeling down at Lotus seems to be that they wont be able to hang on to Kimi"

Added: Boullier "We think we've convinced Kimi to stay here" and "We know Red Bull are pushing hard to get him"

Boullier "We definitely intend to race the device"

Surely it would have been useful to make at least installation lap and not waste time doing that in FP2 if it is dry?

Boullier said there was "no need" to do installation laps when its so wet, Lazenby also said that Kimi had been unwell yesterday, possibly flu ?.

It's disappointing. They just* modified the rear cooling outlet indeed. Looks similar to the Williams now.

Sure it is. Half a second is MASSIVE.

I cant imagine they would have spent all this time working on it if it really wasn't worth much, though.

I've also got to wonder if getting this to work is maybe a priority for them in order to convince Kimi to stay? The device should be good for 2014 still, right?
