Is this a new shape?

Looks the same to me.

Yeah I've been comparing a bit and I would tend to agree.

It would've been a very subtle change. The profile of the bulge on the engine cover looked a bit different. Probably a trick of the lighting.

Simply put the two work in tandem to seal the diffuser, when they work in synergy the effect is much more powerful.

I know that but I was specifically interested why you said the rake between the front wing and bargeboard was more important. I I can't see how that makes any difference to creating vortices where you need them?

But if this area was so performant in the era of EBD the Renault front blowing exhausts would've been the norm instead everyone went for the EBD because controlling tyre squirt gave much more performance.

The bargeboards were much smaller in the v8 era from 2010-2013 to what we have now.

I'm not trying to be obtuse but I'm trying to understand why the rake between the front wing and t-tray is more important than the rake between the front wing and diffuser?

I don't see what the size of the bargeboards has to do with the rake?

It's not more important, it's all connected. Rake angle is an angle, it's invariant between front wing, t-tray and diffuser.

The bargeboards strengthen the flow structures coming off the nose and front wing and in addition to creating downforce on their own they help tremendously in sealing the diffuser. The larger the bargeboards, i.e. the greater the surface area, the greater the aero potential, just like bigger wings on planes produce more lift than smaller wings.

The rake between the diffuser the t-tray/bargeboard footplate and front wing are all different. With the car perfectly level the front wing is higher than the t-tray/bargeboard foot plate, and the diffuser is somewhere in between. When you start adding rake to the car the front wing lowers more than the t-tray/bargeboard foot plate. The difference between the front wing and bargeboard is critical to diffuser sealing because they combine their flow structures which already function to seal the diffuser. Add in larger bargeboards circa 2017 and their potential increases even more than the tiny bargeboards with the previous aero regulations.

It's not more important, it's all connected. Rake angle is an angle, it's invariant between front wing, t-tray and diffuser.

The regulations specify front wing height 75mm higher than the reference plane, the t-tray is practically in line with the step plane, altering the rake angle front to back changes the angular relationship between the front wing and t-tray.

You can easily verify this yourself by tilting two flat pieces of whatever stacked offset off each other. If you tilt it relative to a flat surface eventually you reach an angle where both the top stack and bottom stack both touch the flat surface.

The underside of the t-tray is on the reference plane...the step plane is the underside of the sidepods.

Ah thank you for that.

Made some diagrams.

I think the deflectors will be coming back in France.
