First you need to consider both Cd and frontal aera. I could make a jumbo jet with a low Cd but it would take an enormous amount of power because of the frontal aera.
Second, I don't think that classifies as a production car. The VW XL1 was actually in production even If not available in the USA. It was .189 Cd so it beats the Lightyear's goal.
