<div>Adam Savage has a YouTube video about his Mythbusters test of a car that was covered in golf ball like dimples. They got a 14% improvement in fuel economy. Aptera ought to model this to see if it would help. </div><div>
They did back at the very beginning. Chris said the dimples would have to be rather deep to do much and make it difficult to manufacture. I suspect there is also a large section of laminar flow and the dimples would trip the laminar flow increasing drag.
The Niro and Kona both have this sort of thing going on up front, but they’re traditional automobiles shaped like bricks.
I’m familiar with that mythbusters episode, however, while dimples are good at some speeds, the same dimples are worse at other speeds, it would be ridiculous to have dimples changing size and locations based on speed.
