Even a nicely body paneled crotch rocket will have a higher drag coefficient than a whole lot of cars. For EV to claim the drag coefficient of a motorcycle is no real achievement. The Aptera's coefficient of .15 is very slippery indeed. If I remember a few years back (probably more than a few), Porsche came out with a racing version of the 911 that touted a .38 drag coefficient and that seemed remarkable. FWIW.
