Pretty good view of the HXs here. I'm inclined to think that the entire installation is not that much shorter (fore-aft) rather that the rads are now narrower yet longer. Just a guess. It would fit with their other mass centralization efforts;

--centerline rad divided and moved forward (vs RB19)
--FW adjuster inboard
--sidepod rads flipped 180* (these dual pass radiators now have their return sides facing outward, on both side of the car this can be seen, with the collectors/connex now inboard)
--and now potentially the additional narrowing of these sidepod rads; narrowing them would bring mass inboard
--will they eventually move the steering rack backward as McLaren have?

I love this photo, you can see the duct from the vertical slot (it disappears behind the rest of the cooler ducting without appearing to blend in); with the roll bar duct going straight to a heat exchanger above the ICE, your idea of using the vertical intake for combustion air could have legs - the compressor would create significant suction. Also, it would seem to be a strange idea to use intake air for the ICE to cool other items before going into the turbo compressor - although I can see a certain logic to it.
Any raising of the CoG from moving the upper HX forward will have been more than mitigated by splitting the pod HX’s into an upper (in a ‘standard’ position) and lower (almost laying on the floor).

I wouldn't put it past RB to use the PU to impact aero as they have on the exhaust side in the past. Did RB convert to water to air intercoolers or are they still using air to air? It could be an intercooler on top of the PU that the roll hoop is feeding even though it looks like the lower V is an air to air.

So the radiators are in a v arrangement (>). I wonder where the innermost cooling slot actually goes, as it looks like it doesn't feed into the sidepods from this picture.

It does, if you zoom in on this photo you can see the side vertical duct merges with the “plenum” from the sidepod horizontal intake, distributing cooling air into the V Radiator setup.

lots of new fresh pictures on twitter from the rb. I have to say. The journalists are so easy. RB could have come out with whatever and journalists would have gone crazy. There is no doubt the car is fast, cause rb always is and they know what they are doing, and it has bold choices. But the level of mass histeria with this car at the moment is just. Almost monte pythonsk in its exageration.

Spot on. I think it will be the car to beat but others aren't as far away as Bahrain last year in my opinion.

According to Stella the gap will be bigger compared to Abu Dhabi. Now it's not clear if he was talking about McL only or all the others as well.

Verstappen won with no effort and Perez finished 3rd after starting from P9 and stuck in the midfield for the entire first stint lapping miles faster than everyone else bar Max.

Verstappen won most races with no effort last year

I think both Abu Dhabi and Bahrain tend to exaggerate McLaren weaknesses more given the straights, and traction zones. So I think it would be true that the statement was relative to McLaren. Let us not forget that Charles kept up with Max for most of the first stint and Ferrari being poorer on the harder compounds meant he couldn't do the same for the last stint. This year Ferrari no longer have that issue and historically Ferrari always does well at Bahrain. Even the SF23 was on pace for second (after RB19) before the engine failed for Charles. I think at least as far as Bahrain goes, it won't be 7 tenths or 8 tenths gap that we saw last year. I expect it to be within 3 tenths personally at least between RB and Ferrari.

Some good close-up footage of the car:

The closeup of each (still slightly oblique angle ) sidepod with detail of the primary cooling matrix .... can anyone else "visualise" that the stack of aluminium above what appears to be the liquid coolant plane, and also exit to vacant space at top internal of sidepod, seems possible to be tubes running vertically away from liquid plane ?

In effect a "honeycomb" type arrangement to exit from liquid plane, possibly to extract from each individual site as vertical chimney in multiple.
Used in photography lighting at scource exit to constrain immediate scattered output then to direct it more effectively from scource.

IF so, a possibility to increase surface area in contact with immediate flow conditioning to improvement of primary matrix performance. A hybrid of liquid plane to deliver the heat, then more air management on that panel to extract at higher potential.

Comparison Diffuser RB19(left)/RB20(right)

Now that we can clearly see that the sidepod exists, purely for aero reasons (all the space 'in the V' wedge is empty, the ramming-in air, simply diverges to the two radiator faces - one upwards and one downwards); isn't there now more volume of 'empty chamber' than the RB19 ? What I call as empty chamber is the available volume for the air from the ram-inlet opening until the radiator face.

Isn't there more heat-absorbing-capacity (due to more air) sitting there inside the sidepod, say for the duration in between a car slowing down massively for a 300 degree turn (say turn 10 in Bahrain) and until it accelerates next ? (akin to putting a larger capacitor in parallel to the load in a ckt)

[Farnborough]

The top rear suspension arm different too in the diffuser comparison images.

Primary, topmost link, the same but with next down having more inclination .... looks like the top rear leg ? moved.

It doesn't, they are separate. I'm guessing they feed the turbine inlet as suggested earlier in this thread.

So the triangular split inside the air scope is just part of the roll bar ?

looking at opening size i was thinking that both opening on the sidepods (vertical ad horizontal) was used for side pod radiator... (with separated or joined flux) but you are right from the photos is clear that the vertical inlet go somewhere else..

i'm skeptical about the idea of engine feeding: in an hot summer day the air near the tarmac is hotter, in a wet race it have more spray... so is not a good place to put a engine air intake...

but if they can use the engine suction for some aerodynamic trick.. hat off to Newey.... again...

That's a very interesting theory. Could this be a way to use the engine to drive the aerodynamics again?

That's my guess. And the air it would be ingesting is negligably different in temperature from the roll hoop.

In the first image from this post, look at the vent to outside of the "top tube" exit, noted with a blue arrow ..... now look just behind that on the car to a semicircle carbon shroud sticking up into the air, has the profile of tube internal along with mounting points on it .....seperating front shoulder inlet portion of the tube from the rear outlet, while letting the flow from primary heater matrix to exit out towards the rear near wing.

This panel separates the top tube into two discreet sections.
