Here is our blog at EV World on the aero mods to the Tesla Model 3 needed to extend the range to 440 miles.

The numbers seem off.

Any in-depth writings on the subject that include the math? I've done all sorts of energy consumption calculations on hypothetical builds, and a change in Cd from 0.23 to 0.18 with nothing else altered, seems far too minor a change to go from 247 to 441 miles range. This is showing a 22% reduction in drag coefficient(and nothing else) yielding a 78% increase in range at 75 mph.

The 0.13 Cd mentioned earlier in this topic would get you much closer to it, but even that would fall a little short(a few percentage points).

I'm guessing the comparisons made between the existing and hypothetical aren't like for like and/or there's a computational error somewhere or perhaps I didn't see some additional mods proposed that would get the efficiency where it is shown in the chart in John Gilikson's video. Or maybe John Gilikson meant to say a 0.13 Cd, and not a 0.18 Cd.
