Ferrari 150° Italia

[Robbobnob]

have to hand it to Ferrari, that is some impressive packaging.

Sure makes the Mclaren (from the launch car) seem quite obscene

I don't think that's the case. They've had enough time to manufacture spares. I think difference between both wings might be very slight and specific to circuit or driver linkings.

They'll bring both specs, it's standard practice, teams do it all the time. People just get too dramatic these days.

I know, I remember them bringing both specs for most races last year as after they added third flap.

Red Bull and Ferrari exhausts are both similar and very different.

Basically, they have the same position of the exhaust, but the Ferrari goes over the top of the floor and diffuser and the Red Bull goes under the floor to feed the diffuser.

i agree that the ferrari exhaust gasses go over the top of the floor and not under it but i disagree about the diffuser. i think it doesnt go over the top off the diffuser, just around the sides. the reason i think that is look at the gurney flaps on the diffuser. there is quite a substantial flap on the top endge of the diffuser but none on the sides. makes me think they want to use the exhaust gasses and a virtual surface on both sides of the diffuser.

You could well be right since the exhausts appear to point there, but I think it looks that way mostly from the camera angle. I don't see the point of blowing the exhausts over the floor (energizes and adds velocity to the ambient air) and then try and squeeze it between the diffuser and the inner rear wheels.

The Gurney flap size is even more indication to me that they are blowing it over the top of the diffuser and under the beam wing. If there is more flow, more volume of air, the Gurney will need to be larger to have the same effect as less flow and smaller Gurney. Thus: a very large Gurney flap on top and almost none on the sides (almost no flow in proportion to that which is going over the top of the diffuser).

I think that ferrari aim it is not to blow over the diffuser, nor exactly over the footplate, but instead to make the exhaust spill outside in the region betwen floor and rear wheels and warp around the footplate and increase energy in the side vortex inside the diffuser.

I think gurneys are there to encourage and exploit this effect. Also remeber that gurney's back lower pressure is as important as gurney's front higher pressure: so also gurneys are there to help the diffuser not to separate.

i think this image might confirm your theory shelly:


you can see a small cutout the floor between the tires and the diffuser and what could be a vortex generator at the tip.

thanks for the pics francesc...

Looks like the engine cover got broken somehow just about where the pushrod attaches.


I wonder whose car this is, and whether it'll be replaced before Q1?

Great shots Francesc, well found.

[Robbobnob]

how can the body be broken? they haven't had FP1??

Perhaps someone dropped it during assembly, or maybe it got damaged in transit?

Either way, that edge doesn't look like it was meant to look like that!

[halllo_fireball]

I think this picture makes it quite clear, that the shape has not much to do with damage.

Exactly why does this make it clear? Because it's not on the car? Sorry sir, but rubbish.

More likely, they have had a production miscalculation, and have had to cut a small piece of bodywork away. That is not a smooth line, it almost looks like a tear.

Edit: If anything, this image above shows even more that it's not intentional - the reflection of the light is distinctly different around the area that is in question, perhaps indicating that the bodywork was pushed out from underneath.

[Crabbia]

I'm going to reserve judgement until I see another engine cover. I still think it's intentional. This is carbon fibre ppl. Not ur moms finest china. It's not gonna break in shipping and if it had the black material underneath it would have shown some damage. and the paint is perfect.

As far as manufacturing defect is concerned. Really? Have u seen any of those in formula one? With these levels of QC? Especially considering they had an extra week to prepare for this race. Not likely.

Edit: it is intentional. Look at the first photo of francesc set. You can see that the shape follows the contour of how the suspension arm would come up under full load. (keep in mind the car is on a jack in the photo and hence the suspension arms are fully relaxed) Also, the black material would not show damage, whereas the painted material would. This also allows the engine cover to close the gaps left for the suspension arms. And I'd guess that that black material has a little less friction than a glossy coat of paint scarlet paint if the suspension were to rub against in the case of damage to the car.

Have you ever seen a fractured cfrp laminate?! - This certainly is not.

It is a smooth line, just with the shape of a tear This second picture simply made clear, that this shape was created on purpose and not afterwards with some emergency cutting...
