This is interesting, but... it's not running yet. And, it has nothing to do with Pagani, despite the clickbait video title. If you look closely at the pics they don't even have the plumbing installed. I have a hard time believing the power claims (1000hp? Riiiiiight.), especially since it's all theoretical. Would be sweet if accurate though. Appears to be barely a proof of concept. Blue Ridge could finish it for them.

"saw the engine bay with the wifi watercooling and bluetooth transmission. and immediately checked out. It truly is a testament how deceiving a sema car is when observed closely. he could have an f22 raptor vtol system installed in this car. as long as its powered by fred flinstone, this is an art project."
