It doesn't have a hood panel, from what I can tell, so probably double just from that. Then it's a pretty beefy car so lighter and more aerodynamic ones would get more range. Lastly we will get some more battery & panel improvements. So probably pretty easy to end up in the range I gave.

Maybe 20-40 is too optimistic. But even at 10-20 a day that's going to cover a significant amount of usage. It will cut down the fast charging needed from once a week to once a month or so. That's a significant convenience improvement.
