Mercedes AMG F1 W03

Maybe they don't know how to add rear DF in a way that doesn't completely ruin their drag. And removing the FW cascades is so much easier than redesigning the complete rear.

PS: Your analogies stink. They don't work. Their rear wing isn't kaput (it just doesn't work as well as hoped) and changing something in the front certainly affects the rear (balance- and aero-wise).

Yep it's way easier to stab the 3 remaining tyres then change the flat tyre.

Last year they also lacked grip at the rear. This year with a way longer wheelbase which gives you a larger area to create more downforce and you still lack grip at the rear? Deja Vu?
I agree that removing the fw cascades makes the car more stable. But more stabilizing doesnt neccesarily mean "progres".
Comparing to other teams they are falling back. So their is no progress.

But according to you they are doing whats right. And thats given them p 13 and 18 today. Way to go!

The longer wheelbase doesn't really help to shift DF to the back (granted, a longer floor could help but the main sources of rear DF have nothing to do with wheelbase). Maybe they just can't design a good rear wing or diffuser.

It's not just stability that is affected by a more even balance. A higher front DF would help on turn-in, but if the rears can't work under such cornering it is simply wasted drag. Further it ruins the feel for the drivers (forced to turn the wheel slower, or compensate when the rears slide) and leads to excessive wear.
They didn't try to make progress they where trying to save some points. When they did try to make progress that didn't work either.

May be they are not exploiting the rules by adding fins to the brake ducts at the rear .. no proper airflow under the car, lack of airflow to the beam wing-diffuser, poor internal airflow and their decision not to use the exhaust gasses to target one particular area at the rear..

[Vasconia]

Taking into account that Rosberg will start at 23th position they could re-introduce this new ddrs and start from the pit, at least it could be a good opportunity to check the sistem properly. What do you think?

If they don't take this opportunity... facepalm.

They only time they ran it was on friday which was a washout and since nico had a gearbox problem in warmup they did not get an opportunity to test it completly.. maybe just maybe for monza.. i believe that the passive f-duct will help alot at monza as it can be used anytime and at any given point of the track unlike DRS. But by stalling the rear wing no doubt gives a straight line boost but what gear ratio will they have to set top gear on. and arent the gear ratios set during winter testing ?

This why I say that they shoult test it today, Nico is not going to do anything important today so to check the system will be very valuable. Anyway, they should have prepared it for these two races when its more useful...

Note the difference in the air intakes.

I still think the device is a downforce adder, and I think this confirms it somewhat.

[Owen.C93]

Why.

[beelsebob]

The nice thing about Merc doing this is that they can do it rather better than Lotus – they don't need to tune their "device", as they can use their DDRS's airflow as a fluidic switch for it.

[superdread]

I still think the device is a downforce adder, and I think this confirms it somewhat.

Stalling a wing by blowing air on it from far away seems rather unlikely.

But, as the friction in the duct and the lower exit rob the air (that would otherwise go directly to the wing) of flow rate and energy, wouldn't the system result in a net loss of rear wing DF? (this would be offset by the monkey seat DF or reduced drag of the main wing or something)

These changes were required for Monza so there is nothing new. Let's see what improvement they would come in Singapore. I think by the end of the season we will have one Mercedes driver on the podium

They have the Magny Cours test prior to Singapore, so that will at least help them to get whatever's planned properly tested before that race.

Well, maybe we focus too much on aerodynamic. Maybe they have some serious problems with setting up the car at the suspension area.
Mid-Corner Understeer is often because of a lack of balance between the front and rear suspension.

[marcush.]

i´d think having the left side tyres run too hot and outside the working range and the right side tyres too cold outside the working range hints at a serious problem of understanding or managing weight transfer ...maybe simplified too much weight transferred?

[yener]

They are still improving their top speed. So i would say there is no tyre management problem or they just dont care.

How so?
Their imbalance has put them in the dilemma of either adding rear downforce (which will cost them a lot of drag, as their rear wing is rather inefficient) or losing front downforce (which lowers overall downforce, gives them more top speed but ruins the cornering).
Apparently going for top speed is faster (or Mercedes thinks it's faster), but that's really just a question of setup not of the design of the car.
What they really need is a more efficient rear wing, and in my opinion that is the aim of their blown rear wing (or maybe not).
