Great info! I have an Aptera (claimed Cd of 0.11) on order...
"For comparison: Honda Insight Cd=0.25. Mercedes Benz's Bionic Car and General Motors EV-1 both have a Cd=0.19. Daihatsu UFE-III Cd=0.168. GM Precept Cd=0.163. Aerodynamics in Car Design shows that the Ford Probe IV achieved a Cd=0.152 and the Ford Probe V did even better with a Cd=0.137. "
