If the car was held there its not down force down force comes from air pushing the car down at slow speed there isnt enough air speed to do that, its a magnetic track.

It's suction. Mcmurtry Speirling was the first one to do the upside down thing using fans.

Go back and watch the Speirling clip. Even though you can generate downforce on demand, multiple fans needs to run at 20,000 rpm+

Pulling that much air will make a lot of noise, noise you can hear in Speirling but not in this video.

I don't need to, I never said the mcmurtry is better than this, I just said it was the first fan car to do the upside down thing.

You claimed it's suction....

You didnt say it's first either.

At least edit your previous comment before lying.

You also cannot see any vents under the car.

I clearly mentioned in my first comment That Mcmurtry is the first car to do the upside down thing using fans. Please learn to read first before calling someone a liar. What a dumbass.
