We haven't been running with much rake have we?

their new exhaust design makes absolutely no sense to me as long as the acer duct is still pointing toward the inboard wheel floor junction.

if they are going to mimic the lotus/merc inboard blowing, why not make the coke bottle area narrow like days of old/lotus/merc?

i can understand if they didn't have time to remake the whole internal radiator cooling flow path, but the current design looks like the worst of all worlds to me: messed up coke bottle area flow to the diffuser due to both the physical presence of the acer duct and the unaccellerated exit flow from the acer duct being dumped right into that flow field at the wrong angle. i can't believe that the acer duct shape alone is enough to entrain air down to the floor without the exhaust helping it by blowing from inside it. (and i'll add gary anderson's comment about the extra lift producing area on the upr sidepod, but that is hearsay...)

if they are going to eventually fully mimic the lotus/merc inboard blowing design, no problemo. but why test this in-between design?

i previously got temporarily banned for bad-mothing the ferrari exhaust and aero, but as an aero and mechanical engineer, the design shown today just seems awful.

Really? The times are pretty good for something awful

I see that you didn't change your habits...
I think that it is always extremely difficult to judge a car design from the outside
only lap times and race results will tell.
this morning lap time seems not so bad: early in the morning, hard tyres...

Wow!!! An engineer!!! I do not think Ferrari has any of those!

As you seem more knowledgeable, would you mind posting your analysis of the Merc in that thread?

[Ferrari_Tifosi88]

Hello,

New to this site. I found it looking for updates on the...well... updates lol

I got to say given the track time this morning, these updates look promising, at least i hope so. You guys give a great deal of technical analysis

They didn't mess up the coke bottle area, the cleaned it up. And you're wrong about unaccelerated air from the Acer Ducts.
It's called 'Aspiration', it's been used by teams before mostly in early 2000's and you should have a look at the following paper:
Parra and Kontis in their 2006 paper, Aerodynamic effectiveness of the flow of exhaust gases in a generic formula one car configuration, published in the The Aeronautical Journal

I'll save you some time:

"Due to the characteristic configuration of a Formula One car, the exhaust pipes pass through the chamber located directly behind the radiators. This chamber is normally shaped so that it enhances the outflow of gases. However, an extra outflow could be generated by inserting the exhaust pipe into a bigger diameter duct to create a mixing stream. Such mixing is believed to generate an aspiration along the outer duct, based on the same principles of operation as an ejector pump. Because this enveloping duct connects the chamber behind the radiator with the atmosphere, an outflow of gases through this passage would increase the efficiency of the radiator,"

Anyhow, as I said it looks to me, and to most people that Ferrari have in fact cleaned up the coke bottle area but you're entitled to your opinion. We'll see how these updates work.

edit: notice temp stickers towards bottom of endplate

Looks like they only moved the acer logo

[kebab]

The sidepod actually looks flat from the Shell to the acer.
