Aston Martin AMR22

[Ringleheim]

Looking straight down from above, you notice how little "coke bottle" shape the thing has.

It's interesting as on the one hand you don't want any bodywork at the back for diffuser purposes, but then you want the flanks big for the underbody downforce in that area. So you have to have a balance.

I will be interested to see how other cars handle that dichotomy.

These cars conceptually have taken us back to around 1980, 1981...which is kind of weird.

And damn...they are still such huge, heavy pigs!

The venturi looks like it's doing this... or am i seeing things?!

The two "kinks" could serve to energize the flow to prevent stalling of the diffusser and keep the flow attached while working the floor harder than possible without the kinks?

I was thinking it's to put the diffuser low pressure zone further forward to offset the lower front wing downforce from the higher wing centre

It still looks strange to only have one tail pipe. Like something missing

Nope the wastegate no longer needs to exit at the rear of the car. It can join the main exhaust pipe <450mm from the outlet.

The hinge design is also obviously designed to shed a vortex with that nice big triangle of metal sticking up in to the airflow at a slight angle to the stream.

There also doesn’t seem to be an outer part of the hinge, are they using the remaining outer section as a very big flexure hinge?

Are you not really reading to much into a render of a FW? I mean, only one side of the car has a pushrod

It’s great to finally see a proper impression of a 22 car, but the detail will be vastly different on track, including having proper cooling outlets, suitable for the ambient temperature conditions on that day

Looking forward to see how other teams have handled the sidepod designs before they all converge on the same idea again. It will be interesting to see who’s got the overall airflow philosophy correct

I’m not really sure why they did the launch with renders (really bad ones, at that) and a real car, there is quite a bit of detail on the real car.

The reason for separation of them was to increase the car engine volume isnt it? Why now they are going back to single pipe?

However, cars with long, narrow bellies will seek to mount the engine further back, and may have a short gearbox, and perhaps mount a push rod suspension. By contrast, F1 cars with short bellies will have the engine closer to the driver and will need a long gearbox. In that configuration there could be a pull-rod suspension.

The location of the radiators will also vary greatly depending on the chosen layout: there will be those who keep the elements of the cooling system above the engine (Alpine?) and those who try to place them on the sides.

What a scoop from Nugnes. I noticed too how far back the hump for the plenum was, they've pushed the ICE way back, so what's in all that space between the back of the cockpit and the engine?

I think they worked out it didn't help.

@jjn

Concerning the outside endplate dive plane.

Is therea rule that prevents that from being lowered and becoming a de-facto footplate?

I hope it doesn't decrease the sound, but I personally like this look more.
The waste gate pipes looked so weird

The minimum height is z200 and the rear of it has to be at least 75mm above the front edge

There's something visible in this image at the far end of the front wing. Another little metal triangle. I'm guessing that it is the location of a hinge point.

Certainly looks like it.
It would also appear that both elements (3 & 4) adjust.

I'm not seeing that.

You do realise there are photos of a real car too, right? They show both push rods...

Front directly above, yes there is little coke bottle. But from the front 3/4 view, you see a big under cut for the length of the sidepod. The coke bottle is just hidden from above.

cooling louvers have to sit inside this box - again AM look to have maximized the area they can use

Perhaps maximimizing the cooling openings with the gills has a stronger benefit than having the teardrop shaped side pods with cooling tunneled all the way to the back.

In other words, the Aston side-pods could be shaped the way it is, undercut and all, to get as much side-pod surface as possible into that bounding box so that they can maximise the number of cooling gills. The assumed result being that drag is much reduced and sidepod lift is much reduced.

Again, this hypothesis is only valid IF having the gills is really that much better than facing that drag from tunneling the cooling all the way to back.
