Mercedes GP MGP W01

they should just go and use some tungsten in their diffusor/floor.
would help in more then one way, and solve more then one problem.

maybe they are working on this already..but it takes mooooore time to get the damn tungsten in shape..

to me they look not very pro to me....I always have that famous duckworth quote on my mind :development is only necessary because of ignorance in the original design..or something along these lines..

locate your problem and erase it.they are fiddling around with this since ages....
who decides which carbonfibre system to use..they seem to lag in terms of plan B
or have no good analyses leading to their decision to do things ...as they had
coking floors since hour one ...had expected ferrari to struggle there ...

I am probably showing my ignorance here guys, so sorry for wasting your time... BUT

How is Merc's F-Duct supposed to work given that they do not have a sharkfin attached to their RW? How is the air supposed to be vented?

I have seen the "nostril" shaped things, but I can't see how they can be controllable by the driver, unless there's something very sneaky going on there.

it passes through the endplates....its an active system

I heard speculation that this was the case some time ago, but never saw any convincing evidence of this.

If it were true, there must therefore be huge losses in the air pressure arriving at the wing, unless of course it's only "signal" air which passes through the endplates and they've fitted the fluidic switch ON the wing. Given the size of the "nostrils", I suppose this is possible, but that would make the configuration of their system significantly different to that employed by every other F-Duct running team.

Do you have any images which support the theory?

The system was active in Spa as evidenced by Michael Schumacher using his left hand to seal the hole in FP1. Later they moved the hole lower down to make it knee operated. Micheal asked the team several times over the radio if the F-duct was working and they confirmed the system was working properly. The pitty is, this system seems to give a very poor stall compared to what all the other teams are doing. Force India seems to have a lot less drag and easily had more speed up the Kemel straight.

If you watched the shots of Schumi moving his hand, he did not hold it there for more than 2 secs, and then did the same action at the end of the straight. So any system did not require the activation hole to be continuously closed. You mention the hole being moved lower down, to knee height. Would this have been allowed? The tub cannot be modified, and there is no mention of any change in the stewards technical report.

The worrying thing for mercedes gp is the straight line speed of their car. The Mclaren & Force India have the best straight line speed and their F-Duct system works well, but Mercedes GP seems to be slower. Can anyone explain why is this happening to the team?

The W01 is probably in-between if the Mclaren and the F-India which makes them less aero-efficient than the mp4/25 but more downforce than the VJM which is gonna hurt them on tracks like Spa and Monza.

Just an inefficient car. They're having to up the AoA to get the downforce they lack in the corners but it really does hamper them on the straights. Stuck between a rock and a hard place.

[marcush.]

if they had more downforce than Force india how come they are slower through eau rouge allowing them to eat into their lead with ease....I´d think they have compromised exit speeds too much in their aim to adapt the car to the drivers liking maybe..or it really was just a factor of having an issue in eau rouge and paying the price in the run up to les combes.

the FI was even faster than RBRs in the eau rouge

so how much was the difference between fi and merc in eau rouge?

[siskue2005]

no idea , but one of the FI just swept past RBR(Vettel) through the Eau rouge
He did the same with Mercs aswell

[marcush.]

you ´d need a massive speeddifference through eau rouge to perform an overtaking move up to les combes.. say 15kph....thats a lot. possibly thes emoves were owed mor eto mistakes by the guys in front ...?

I don´t know what happend in Eau Rouge, but if a car would bottom out massivly there and another not, that could lead to some extra speed up the hill. IMO
