I’m not sure that it does. All the articles I can find word it as something like “has a range of 710 kilometers (441 miles) on a sunny day.”, without actually explaining it. I’m assuming that’s going from 100% charge to 0% charge, plus all the range gained by charging during the day.

They don’t actually say anywhere I can find how quickly it charges.

Also, looking up some other articles about it, apparently there’s a bunch of extra fold-out solar panels in the trunk

If you wanted maximum range, you’d start before dawn, drive most of your battery away, park somewhere all day to use that solar awning for all its worth, then continue driving at dusk.
