I don't understand why you're going to so much effort to be wrong. The Lightyear One's drag coefficient is under 0.2, the Model S has a drag coefficient of 0.24. The Lightyear One is lower and narrower than the Model S. The Lightyear One is lighter than the Model S. The Lighyear One has in-wheel motors for greater efficiency, the Model S doesn't and neither did the EV1.

Again, reading.
