As a software-limited S60 owner, I haven't found the 210 mile range estimate very problematic but we usually fly for long distance travel. But on my limited road trips requiring Supercharging I definitely could have used another 20-30 miles of range. On the other hand, the fact the physical battery is actually a 75 limits Supercharging taper and allows a full 210 mile charge without unduly tying up a Supercharger. The base 3 with 215 mile rated range would obviously be similar 100% range to my S, but Supercharging to 100% with taper will be much slower. Superchargers will surely be overtaxed as 3 comes online and that means we shouldn't charge to 100% when others are waiting. But if you only Supercharge a 215 range car to 80 or 90% while long distance traveling, range anxiety won't be an imagined disorder. Hopefully, the larger 3 battery won't carry the same hefty price of the 60 to 75 upgrade. I would consider the base 3 battery if it had a software upgrade option for the future, but that seems unlikely. So I guess that means springing for the upgraded battery even if that jacks the price up considerably.
