Aint it better to have the geometries inside RV_Floor_fence, RV_Floor_led and RV_Bargeboards on the high_res_surfaces? According to the ruleset only the wings are allowed on the said folder.

MFlow will automatically add refinement in these areas.

So another question for clarifying things. Last year almost everyone extended their diffuser starting point outside of the floor legality volume where the volume meets with the vehiclebody legality volume for a bigger kick. Is it still allowed even though the rules says "be fully contained within RV-Floor_V*"?

Well, from my point of view, this wasn’t legal even in 2024, but I know that some teams did it. Let’s wait and see what the Staff says.

Can't resist a little teaser. First run is in the books.

You deserve 10 more points in the standings for showing that so early! Can I publish it on LinedIn?

Wow, nice job mate. Can you share roughly how much is the downforce loss compared to the previous regulations? :)

With the wheels off the ground as they appear to be in his run, the values will be meaningless at this stage. I've bodged wheels into the ground for a run and a crude car was half of the downforce that we achieved last year 😅

Yeah I noticed that too, something with the ride height settings in old Mflow seems to not work with this car right now.

According to the FIA the 2026 cars are supposed to be about 30% less downforce than last year, I think that sounds about right so far.

Subtract the downforce the wheels are making by being off the ground and get back to me haha

Hi guys,
my friend just told me about this competition and I would love to share my 2026 car that I have been developing since the new year. Here is the pressure distribution and you can find many more details on my X page

Quick question on the mflow side, will the new version translate the wheels and hubs to their new position or will there be an update to the mandatory parts?

Don't want to do too much work before the wheel position is final as I suspect it'll have a significant impact to the wake

Looks like you've been busy. You should enter! I suspect you'd need to develop a new car to meet the mvrc rules, particularly about surface thickness but the more the merrier!

I've actually seen your car on there for a while now, and it's got some nice details that I totally am not trying to replicate and failing to. But anyway you should join it's pretty fun here
