A place to discuss the characteristics of the cars in Formula One, both current as well as historical. Laptimes, driver worshipping and team chatter do not belong here.
It's not black magic, it's a rather simple effect from having a couple of almost vertical vanes strapped on either side of the crash structure, like every other team.
I think the most interesting bit there is you can see how the vortex generators just in front of those vertical diffuser/cs tabs work and help keep the upwash going to the rear wing.
The rearward segment of the underr-nose turning vanes is funny looking; it looks to me like a waiter's hand that is politely saying to the air to go "this way"
