812 VS Rumors

@isot
And, those vents may actually be related to "heat ventilation" from the transmission, and, maybe, some extra source of power under the trunk deck...

 

Oh.. it could be...
But do you really think there is something in the trunk? There is a nice emergency kit, warning triangle and a bag with screwdriver and wrench

Fully agree !!!
Over 200 days on tracks in different Lotus....and yess light is right!
I love my Pista , ,,, but is is a different world...

I haven’t seen any of the main Youtubers getting one. Shmee, Mr JWW, theCarGuys, Salomondrin, Dragtimes,...

 

Have a look !!



But once again do not misunderstand me..,
I was just reaction to a post ...
I am lucky to have some Ferraris and love them ...

To

the regulations are putting a huge pressure on the car factories and I think Ferrari is doing bettes than others to keep the “Dna”
Even light cars manufacturers were obliged to increase the weight ...
But I will never deny the importance to try to keep the weight low...

Totally agree, my only other (additional) theory for the turning vanes which I am wrestling with is they produce an invisible vortex (tube of pressure) which runs down the side of the ‘C’ pillar sealing the flow on the rear deck and ensuring air is not ‘bled’ off the roof and directed on the rear wing...in addition there would be that high energy vortex on the outside of the wing in that complex zone where the wheel arch and winglets are, where they are clearly managing downforce and drag....tricky

Perhaps it’s a combination, would love to put it in a wind tunnel and see the actual results, I am sure we will get a graphic.

Question, why did they go out of their way to may the trunk difficult to use, that is, if it is a trunk. From the images, it does not open all the way to the rear, instead it lifts open inside the raised lip/spoiler. That is not a very useful approach...unless, it is not a trunk at all and that is instead a service cover not intended for cargo....

I don't see anything strange about it. I think the tailgate opens with a button and the usual luggage is provided to be placed in the trunk and on the bench behind the seats.

 

I cannot imagine that Ferrari would use a mechanized trunk liftgate (extra weight). The fact remains, it is very unusual. When combined with the extra tail depth and how far away you must stand (yellow line below) to even touch the trunk cover much less extend your reach to close it when full open, not to mention how difficult it will be to apply sufficient closing force when its on the other side of the raised spoiler....and below it as well...

I think there is something we don't know happening...

but, maybe it is carbon fiber and not aluminum and feather-light and requires very little force to close? But, still, to have to reach over the raised spoiler is odd for a cargo bay.

 

It looks like there's a seam for the rear to open right here. Image Unavailable, Please Login

 

On the aperta version, there has to be at least enough of a trunk to fit the hardtop.

Given that the two versions of the car won't differ internally (e.g. in terms of drivetrain / powertrain), the coupe's trunk should be at least as voluminous as the aperta's. If anything, because of the rear-end design differences, the aperta is likely to have a less useful trunk, even without the hardtop in it.

 

Those are the split lines for the bumper. The other bumper EOP (end of part) is below the spoiler at the sides of the rear fender.

Trunk lid was probably done this way to reduce complexity and weight of hatch and have a cleaner look at the back.

 

I think the aperta hardtop will stay at home, will not have anywhere to store it in the car, look how narrow it is compared to the space it would require...(see next post for image)

 

I don't think that is what is going on, image:

If instead it looked like this (removed seams) then I could see that

I think it'll fit in the car. We'll hopefully find out in a few days.

 

About the side vortices and vortex cones, these exist already in any fastback car, as shown below, created by the air flowing along the side windows and migrating towards the low pressure area at the roof:

Not sure how the flow off the VGs would interact with the vortex cones but I would expect their influence to be relatively small considering the volumes of flow involved.

One thing is for certain, there is not much downforce on the "trunk bonnet" otherwise it would crush/contort.

And, it appears it is at angle of 20-25 degrees before the spoiler lip, according to the link above that would reach optimum drag coefficient, the 'vortex generators' definitely disrupt the airflow, unclear, apart from dressing up an otherwise featureless surface, what their net benefit is.

Hopefully Ferrari will share their discoveries, otherwise it may just be a design feature with minimal performance benefit.

 

Yes thank you all, this is what Im curious about. When I look at the pics I see these as vents, but I suppose they could also be folds or something else.

 

I think it will open like a traditional boot. I think the rear panel can also be removed. My guess says two things going on here. Cut lines in the spoiler are for the entire boot to open and cut lines around the vented panel are so it can be removed. I imagine it’s either metal or glass underneath.

 

From this (1m52s forward)


it would appear the 'boomerang shaped vortex generators' of the 812VS would disrupt the airflow, impairing the ability to generate down-force at the tail, and, they do not appear to be actual vortex generators, only the "shark tail" housing the rear view camera is the shape of a vortex generator...so, those "carbon angles" on the back cover may be purely cosmetic...

found this interesting:
https://www.carthrottle.com/post/vortex-generators-how-do-they-work/

"On airplanes and Formula One cars, vortex generators are sharp-edged and often triangular to create the most effective vortex possible at very high speeds."

 

YESSS!

Ok now back on track....
When someone is ready to sell their Bianco Italia 812 Competizione, please let me know so I may find its fraternal twin.

I think that the louvered rear panel that is in place of the windshield is just the solid equivalent of the rear hatch lid. I'm going to say that there is absolutely nothing going on in the trunk. Its the same as the F12 and the 812. The lid opens the same way and it does not lift off because there is a camera on there that would have to unhook which sucks for a video connection. The seam that you are talking about is just the assembly seam between the CF bumper and the aluminum body. There is no difference here other than the windshield is gone which now seems a lazy approach after all the hype.

I think the noise we heard in the video is faked. In addition, there will be a marketing blurb or two about the aero improvement of the three slots behind the rear wheels but its just another repeat of a design element re-used from other Ferraris which is common for this design staff. Still wanting to know about the engine mods. The slow drip of info and the multiple release attempts has run its course for me. I bet next time they don't do this approach.
