Curiosity, on the other hand, is a car that actually hovered, and that was on Mars, in 2012. https://youtu.be/Ki_Af_o9Q9s?is=uepnp2XLG81tHacn
I expect a future Bonneville speed run to get airborne and set some record. Could still qualify as fastest production car; even with no wheels on the ground.
Ok, I hadn't seen the jump video when I wrote the above. That's more impressive than the ramp video.
