Suction as I understand it, it had a ground curtain and the blurb talked about the ability to create downforce to keep the roadster version on the road at high speeds.

The same fans that blew downwards to create lift were likely first run to suck it in to the ramp, then reversed.

These demos were not performed by "daily driver" cars - they were multiple look alike props in a magic show, each optimised for the trick shot and not driver comfort or experience (if any driver(s) even took part).

That's a nice theory, but it is wrong.

The fans that are used to create suction do not create lift. The amount of air moved by those fans is way too small to create lift, the lift is entirely due to compressed air used as reaction mass.

  • Fair point, I was thinking the same when I wrote the comment <shrug> .. I still side with the reverse hovercraft sucking force .. and thinking they likely reversed those fans after the need for suction passed (every little bit counts).

    On a tangent, I prefer this two year old locally garage built "flying boat" to Musks "maybe one day" car prop: https://www.youtube.com/watch?v=1ILbQHnHPnY

    ( FYI - there's a couple of Dutch boats down there ... )
