dont think it will work, as now you actually remove the positive effect the end plate has on the wing, it now actually is one wing. You could do it with sharper bends, as then on the underside you will still keep the positive effect of those end plates.

It looks to me like your trying to make a giant veturi with that endplate design. Regardless if it will work better than your previous design, it sure is a very complex looking design, must have been quite difficult to model. I'm actually quite eager to see what you have come up with for your 2010 car. This talk of a redesigned rear end makes me want to see just how complex you can possibly make it.
Keep up the good work.

watching and reading how all these developments are enfolding is fascinating.
A quick query, what dimensions are being used for the airbox intake dimensions as i have yet to find them through the regs??
Thanks in regards

Ok, huge update - the 2010 car;
to summarise the changes first, i have mainly changed the rear of the car - it has lower rear bodywork, completely new rear suspension and a new diffuser. I have also made some other changes all over the car including a revised front wing and a new splitter.
Also, consider it a winter testing version as it has minimal cooling at the moment

i have modified the front wing endplate to have a slightly sharper bend

I have completely redesigned the front splitter so that it no longer directs are underneath the floor. This new design is more in keeping with normal f1 cars.

I have added another fin infront of the sidepods to better direct the air. I have also changed the geometry at the start of the floor.

I have added a opening in the floor like many f1 cars have

I have repositioned the wings on the airbox, moving them upwards

I have redone the exhaust exit to make it more simple, so hopefully the airflow is smoother. This picture also shows the lower sidepods and the pullrod rear suspension

This picture shows the rear suspension, which is completely new. It has a very agressive forward sweep to make more room for the diffuser...

This picture shows the diffuser and the lower rear wing element. The second deck is larger and no longer obstructed by suspension elements, also the lower rear wing element has a shorter chord at the centre and outside edges.

another pic of the diffuser

this picture shows the cutout in the centre of the diffuser, inspired by brawn's, and the larger hole in the floor.

holy ---, that diffuser is sick. I can say one bad thing about it, and that is how the hole bends outwards to the rear wing end plates, it wil simply collide, might want to use therear wing end plate to use this bend make the bend extend until the rear end.
Also on the front wing, you have placed a gurney on a gurney, i do not understand the idea of it.
also i would rather make the airbox wing have a neutral AoA as now it disrupts airflow to the rear wing.
Also the way the exhaust exits is bad, if you throw it backwards it has a low pressure area for the exhaust to blow in, now it has to blow in a way it disrupts the surface airflow.
also(now im busy eh

) you could make the bodywork alot tighter, to be clear the ferraris rear packaging was alot tighter and that car has tighter bodywork at the rear.

Where the hole bends outwards i have changed the endplate so its like toyota's to try and avoid that problem
The second gurney tap on the front wing is to try and stop some air spilling over the top of the endplate
I'll probably change the airbox wing angle of attack now i think about it
Those exhaust are temporary
Regarding the rear bodywork, it is as tight as it could be without limiting the diffuser channels; basically i could make it smaller but i dont want to as it would negativelly affect the diffuser

Small update - revised airbox fin and a new exhaust

the fin now has a neutral angle of attack

mclaren style exhaust

wow, that is certainly looking nice.
But something i do not understand right now is how you think tightening the sidepods reduces efficiency of the diffuser, i think it increases efficiency, as the air around the sidepods is alot cleaner then that went through

a few updates:

A new bargeboard with isnt as as aggressive, and a new fin in the sidepod area

Similar to williams, i have added downforce generating wings onto the front brake ducts.
I have made a few modifications to the front wing:

A: I have added an original extrusion to stop air from the upper deck of the front wing going over the top of the endplate and colliding with the front wheel, it works in combination with B
B: I have extended the upper deck, to join onto the brawn style fin, to make a low pressure area underneath it to aid in sending the upper side of the airflow of the front wing's lower deck around the outside of the front wheel
C: I have moved the droop 50mm towards the centre line so it is more in line with the front wheel's edge
D: I have made the central part of the 3rd element more complicated and wavy, so it is more similar to most teams designs.

Yet again great work, that diffuser looks really amazing and your rear suspension layout looks really fantastic. The brake ducts are interesting to say the least of them and your splitter looks great. Im not really sure that you would really need the extra turning vane underneath the side pod like you have put, but in any case, it looks cool.
I'm quite eager to see your next update.

Wow. That's a lot of hard work! Makes F1.08 look simplistic
