Mercedes AMG F1 W05

We'll see. Coming race will give very subtle hints towards it. The downforce package run on Canada will partly shape how the W05 will go to Spa. Especially underfloor development will be determining it.

Agree. Merc may very we see that the straight line speed and acceleration gained by substantially reducing DF could outweigh whatever is made up in the twisties. I'm certain the calculations for such things has been poured over for quite some time.


And whoever posted that rb10's ability to go flat through some turns was dead right that it only has to do with the Merc engine having so much more power. W05 I'm sure is set up different than that of A lower powered car due to it's significant power advantage as well, the car behaves very different starting with the squat (off and on camber) W05 must churn out with the amount of torque it carries. The telemetry charts must be a hyperbole to that of everyone else

Maybe. Not convinced though. W05 wasn't flat trough T16 in barcelona, whereas RBs were. I'd say RB10 is more likely to take it flat as the renault PU has a lot less grunt.
Also, in china vet and ric were on 100% throttle half was trough the long T13, both mercs had to wait almost till the end to go flat out. Exit speed was almost the same, just that merc had too much power available mid corner, so it wasn't possible to just floor it and ride the wave of downforce to carry you trough.
I expect a similar situation in eau rouge.

Right, that doesn't necessarily mean Merc has less DF, it could be that it has more torque available given the pedal demand. If exit speed was almost the same, both cars are likely similar on DF. So in Spa, we'll have to look at speed through eau rouge more than pedal position.

Yes, that's what I said.

double monkey seat Like Montecarlo ...

[astracrazy]

its the same design but i don't think its the same - at least by comparing it to this picture



the bottom element looks like a shallower aoa (more horizontal). Can't be confirmed though until we see better pictures

[OO7]

They look the same to me.

They look the same to me.

It''s the same setup look at p.145 from pictures off the monkeyseat from the MonacoGP.

If you look at the Monaco one there is a more horizontal black piece above it, I think it looks more horizontal from the front than it does the back (I think both are the same).

[dren]

Looks the same to me as well.

[astracrazy]

i don't think i explained the part i'm looking at properly i was talking about the very bottom bit of the multi element monkey seat. But it wouldn't make sense anyway to lower the aoa of this anyway so i'm looking for something thats not there i think

[turbof1]

Could very well be that it got shipped this way out of Monaco. It's very time-consuming to completely strip down the car, so they only dissasemble what is necessary to get it all packed and shipped in time; then they have enough time in Canada to to remove and add parts to have a correct Canada set up.

It could also be a permanent solution, this monkey seat. Above all, I really don't believe it's a new one.

[zioture]

Wait and see, but my opinion this monkey seat is similar to the operation of the exhaust blown

The very long 8th gear chosen by Mercedes, so that they have almost exclusively ran using 7th, might actually have been compromising the W05hybrid so far. It is good for 480Km/h at 15000rpm or, more realistically, 360Km/h at 11250rpm, but it is compromising the transition to the other gears. Where would they be with shorter or more closely spaced gears ?

In the graph below the diagonal lines extend to 13000rpm. I've laid down vertical markers at 10500 and 12500rpm, which I arbitrarily choose as the range one would like to be in, and horizontal markers at 10500 after the upshift. When upshifting from 4th to 5th or from 5th to 6th, they have to get well out of that range (other teams not, or just barely).
The crossover points I calculate for being at 10500 after the shift are:

Shift up to:    2nd     3rd     4th     5th     6th     7th     8th
Shift rpm:     12405   12617   12763   13133   12956   12469   11601

Either they are going all the way to 13000rpm all the time (might well be that the power unit is that good, after all Force India made a similar choice), or they are shifting to 10200rpm or something like that, reducing the fuel allocation by a tiny margin for a fraction of time (my theory is that this is a feature, not a bug, in a car in the high side of fuel usage). It is difficult to tell from the telemetry overlays as there is some sort of time averaging going on, meaning that we do not get to see the real rpm just before and after the shift.
They could have left 4th and 8th where they are but chosen more closely spaced 5th, 6th and 7th. Somehow they chose not to. Why? Is there any reason to almost completely avoid using 8th gear? Any significant advantage to doing less shifts?
