I just don't think lowering the car makes it more fuel efficient. A vacuum is created beneath the vehicle which I think creates drag. Formula F1 race cars are low to the ground so they can turn at high speed because this vacuum keeps the car on the ground.

I know it's accepted in theory but that doesn't mean it's correct. I firmly believe that raising the car up with thinner wheels provides a better Cd (with a smooth underbelly that is).

I have a feeling it's part of the reason that the Aptera achieves higher than 200 MPG.

I'm not trying pick a fight, I'm just trying to get everyone thinking.
