The guy in the video says that we will most likely never see this car on the streets (those were his exact words, but he said in a way that was meant to sound more like, "we will never see this car on the streets"). A couple other things he mentioned:
The GTP5 version runs on hydrogen and has 800 horsepower, while this prototype has some "secret" (as in unknown, not familiar, funny looking, etc.) V8 engine with only 550HP.
That the guy that was driving the car is the only person that knows how to drive it, because the gearbox is tough to operate and can be easily damaged (I think there is no gearbox to operate in GTP5).
This car does not have a reverse gear, so if you get stuck somewhere then you would have to push it.
The model was only built so people can see it in motion.
It is about 1 meter high and 5 meters long.
He also broke the door handle while trying to get out.
He says that take off still feels more like taking off in a jet then in a car.
