The Tesla Model S has a Coefficient of drag * area (or CdA) [1] of 0.562 m² so to have 40% less drag, the Lightyear One will need a CdA of 0.337 m² or better. (Choosing the Model S as I can't find CdA figures for the Model 3)

The GM EV1 only seats 2 passengers, it's 1.77 m wide and 1.28m high, it even has fender skirts [2]. Its CdA of 0.367m² is still only 35% below the Tesla.

The Lightyear One seats "5 adult passengers", and it's 1.90m wide and 1.43m high.

So the Lightyear One is wider, higher, and has 3 more passengers than the EV1 - but it's going to have less drag?

One of us might not be reading what's in front of us, but I don't think it's me :-p

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.
