What kind of material is this? It looks like optical fiber, I've never seen anything similar in F1 before.

It'll be the wheel tether, just with all the threads unbunched after the stress of the crash.

Hey guys, Im new to this forum but I have been obsessed with it for a while and thanks to you I can follow the development of E21 on regular basis... Anyway back to the subject... I have noticed something on E21 that hasnt been there before...

Any idea what that might be?

Any idea what that might be?

As i can not find this on any of the other pics from this weekend, i would say it's nothing but a strange reflection. any other thoughts?

[Huntresa]

Isnt it just Monaco suspension ?

[marco.pav94]

It could be a sensor but i don't know what that might be useful...

Notice breaks in the floor around the E21's unique barge boards. I am no aero guy but what are they trying to do? I've heard James Allison talking about the potential of the forward facing exhaust seems they have a design philosophy surrounding the leading edge of the floor in that area.

I was thinking the same, it seems to be very innovative in my eyes! It must work otherwise it wouldn't be there

What breaks you mean exactly ?

It's the same design since 2011... Because of the backward swept sidepods, they need to extend one part of the floor's leading edge to meet that rule that stipulates that no bodywork part can be seen from underneath the car etc. So that extention's first purpose is to hide the additionnal crash structure they placed on the upper sidepod lip. Maybe you mean the space between the floor's turning vane and that extention ?
The MP4 28 has a similar design

Turning vanes do the opposite. They increase downforce by isolating the conditioned flow under the nose from the unconditioned flow outside. They are basically end plates for the under nose. Kind of like a diffuser end plate.

I tend to think the bulb does mostly the same. It keeps the air under the central section of the nose by creating a low pressure zone in the cnter, thereby reducing spillage to the sides. Would be interesting to know the cross section over the length of the nose. Because only the central section goes up again slightly behind the bulb I think looking at the volume of the nose cross section there will be no overall adverse pressure gradient behind the bulb.
