RB20 speculation

[lio007]

Did some messing around with various photos and ended up with this one that might give the best view of the inlets so far

The part of the engine cover, where the Honda badge is located looks really odd from that angle.

I think we'll see quite aggressive slides on the engine cover between the massive wall and the engine cover proper. Potentially they have facility to fit cooling louvres on the inside face of the 'wall' and contain the cooling losses and cockpit losses in that area before moving them down towards the beam wing.

Something like this where your cooling outlets are in blue. But potentially a more aggressive downwash in the channel too. Not to mention my engine cover is enormous in comparison etc.etc. You'll have to forgive the sloppy 5 minute CAD job, but I think it illustrates the point.

I'm not sure that RB will retain their aerodynamic efficiency with these changes.

What if that strange engine cover is a device to stall the rear-end under certain conditions?

Based on what? It was not an accident the previous two cars were aerodynamically efficient. It's part of their philosophy. I'd be very surprised if this car wasn't less draggy than RB19.

I have linked this video before. I think this is the best video to see the inlet. Pause at 17 sec and move the video a bit back and forth. The dark patch is the inlet.

I think that's right. The opening seems similar to last year, it's just that the inlet has a roof instead of a ledge.

Would be funny if there's an S duct or a vertical W14 inlet in the end

I feel like an s-duct is possible

To me all signs point to a low drag ethos, even moreso than '22 & '23.
Carved out roll hoop
Blended halo mounting
Changed from a slotted nose to a simpler nose
Smooth continuous sidepod topside
Noisy air ahead of sidepod funneled outboard incl inlet spillover

Aside regarding RB20 generally: they flipped the sidepod inlet 180*, added waterslides and W14 engine cover shoulders, yet many incl. myself were expecting a conservative evolution of the RB19, and Newey even mentioned they may have been to too timid, yet this seems not to be the case. This may point to the RB19 being more of a RB18B as some have surmised, which suggests the RB18 line, as good as it was, wasn't apparently the optimal form for the '22 aero regs while all the while suggesting that it was. Will the RB20 philosophy be better than the RB18 philosophy? Time will tell.

Might be possible on the shoulders but wouldn't be legal in the main waterslide/gulley due to the legality box for the louvers which is pretty high up at its lowest face nor does it rise up to the top of the engine cover which might also preclude louvers in the shoulder valleys/waterslides, whatever we're calling them. Did Merc, AMR, or anyone else install louvers inside the shoulder gulleys last season?

Could they put them in the top face of the shoulder like a 2007 "chimney"?

Merc had louvers in them last year.

They could do the slots like on the 2022 Ferrari's "bathtub" sidepods

Tbh in this video I can see vertical line there. For me it's visible from 0:10 to 0:13. If I had to bet I would bet that RB20 will have an S-duct
