Very plausible
What would be the interaction in yaw between mid wing vortex and rear tyre squirt? What would happen if it has bad behaviour in yaw? I heard this weekend Mercedes has a certain limit of yaw angles in their wind tunnel, 33% less than Red Bull, could this behaviour in yaw angles above their limit produce correlation issues?PlatinumZealot wrote: ↑27 Feb 2023, 00:07Mercedes - Side pods wing pulls air down, but slim body brings in clean in-wash The large side pod wing, also makes a large vortex that is not possible with other designs. Result - Strong performance in yaw and lower speed turns.
It's only a hypothesis of course.
2022 it was reported that Hamilton gained 12 km/h top speed using a low-downforce wing in Canada.stonehenge wrote: ↑27 Feb 2023, 14:37Does anyone have a clue how much the impact of the rear wing on top speed is? Red Bull was running the optimal rear wing for Bahrain and got to a top speed of 326.9 km/h. Mercedes, with the barn door, got to 321.1 km/h. Obviously, we don't know what the fuel loads and engine modes were and so on, but I was still curious if, in theory, the new rear wing that Mercedes will bring next week could make up that difference or if the rear wing can only make up 1-2 km/h. If anyone has an idea I'd be very interested to know!
IIRC it was Geoff Willis who spec'd the BAR tunnel that Merc uses and is still with the team
Thanks! That's quite interesting. I suspect the difference won't be quite that much, but who knows. Mike Elliott said that they focused a lot of their development time over the winter improving the efficiency, so I do expect them to gain quite a bit on top speed next weekend. Efficiency seems a fairly reliable thing to develop and probably doesn't involve the same sim-to-track correlation issues as other areas. So it was a little strange to see Mercedes seem to lack so much top speed in testing. Could be some evidence of them holding back quite a bit. But really, we just need to wait and see, don't we?torpor wrote: ↑27 Feb 2023, 15:492022 it was reported that Hamilton gained 12 km/h top speed using a low-downforce wing in Canada.stonehenge wrote: ↑27 Feb 2023, 14:37Does anyone have a clue how much the impact of the rear wing on top speed is?

The comparison with Aston Martin is interesting for Mercedes because they supply Aston Martin with the engine, gearbox and rear suspension.

I believe its due to the whole aero-mechanics concept and aero maps. I don't want to pretend I know exactly how it works, but my guess is that, if they run the car that low, the way they generate downforce would be uncontrollable and my guess is that when Wolf says 'our floor would break' he means bouncing or porpoising uncontrollably to the point that the floor has not been designed to sustain that force tolerance.Venturiation wrote: ↑28 Feb 2023, 00:35pursue_one's wrote: ↑27 Feb 2023, 23:59AMuS reports that apparently the ground clearance of the RB19 is at least 10 millimetres below everyone else.

Can someone explain what else affects the ride height and how is Mercedes is limited while using the same suspension as amr23?
Could it be just setup of the rear suspension or more the floor shape and front suspension
