Any pics, news or informations about the F1248 "evo" or "B" ?

I think it may have been speed tv in the states, but they were talking about the carbon ring on the wheels... something to do with the removing of air turbulane in the wheels at speed. Can anyone else confirm this?

Also, I love the shark gills on the top of the left side pod. The shark is back!

The little carbonfiber strip on the rim surely is to lower drag. Optimally you'd run a sort of hubcap flush with the sidewall so the air can slip over and not hit the turbulant air of the circling rim, however this would close the rim and hurt temperatures and be 100% a movable aero devise. Perhaps this strip makes a tornado type effect inside the rim to pull the hot air from the brakes out, and can then be legal. I dont see this one lasting though haha.

SF1 where did you get that high res pic...its awesome...links please

thanks

Wow nice one SF1. About point 4, i thought that aerodynamic devices on wheels or suspension that create downforce are illegal?

Well I called it a wing (which is probably the thing that makes you think it produces downforce) as that is what it effectively is. I think you're right saying that it isn't allowed to generate downforce therefore it is probably there to reduce drag or/and make the air less turbulent.

"The Thing" in front of the brakes are brake coolers if im correct.

They suck in air to cool the brakes. Was explained somewhere last year (the F2005 had them as well).

They were originally pitched as brake ducts untill it became blatantly obvious that no air went through them (became known as zero-flow brake ducts) I believe originally thought up by another team, but taken to an extreme by Ferrari.

They were technically illegal in the past, and were I believe removed for a few races last season due to protests from other teams.
For this season the FIA changed their minds and they became totally legal as aero devices and are actually fitted to a few cars up and down the grid, just not so prominant on the top like on the Ferrari.

They are designed to add downforce on the front axle (and thus the front tyres)

If you look how it's made....a lip, sort of, it's got to produce added downforce, by trapping the air in the rim.....doesn't it?

I think it would be difficult for it to generate downforce on its own, although modifying the air flow over the whole car can generate downforce elsewhere.

I was thinking along a similar line - definately looks like something to do with drag reduction or improved brake cooling.

It's called 'anello' in Italian.

Which imaginitively enough means "ring"

Yes that was what the dictionary said but wasn't sure ''ring'' was the right word to apply to this matter....

well it is a ring of carbon, but yes, its more of a lip or flange as far as the wheel as a whole is concerned.

Brawn about the rearsuspension: ''Our simulations show that over one lap it makes a great difference, but the tyres aren't stressed so heavily. We only need to use softer compounds to benefit from it.''

''The advantage of a seamless gearbox isn't as big as people think. We will introduce it when we're happy with the reliability but we're not at the moment. We have to see the advantage in speed we get from it.''

[S.F. 1]

Brawn about the seamless gearbox: ''It appeares to be a hot item, but as far as I know Renault doesn' have this system. I'd say the gain in laptime of 0,4 seconds is a bit too optimistic. In that respect, other developments would have a higher priority.''

''The new rearsuspension for instance demanded a new gearboxhousing. This had a higher priority.''

''A problem with a seamless gearbox is the instability that a gearshift can cause to the engine when you don't manage it properly. You could get some dangerous vibrations in the engine.''

This is a very nice topic very intresting info thanks a lot dudes

Actually it has been and there were complaints by other team at that race that it was actually used as a moving aerodynamic device as well !
