In an interesting turn of events there is a pack upgrade for the i3 that gives it more range than it started with!

This is the kind of hacking / upgrades I’d love to see. All in cost was about $6k when I last checked probably a little more now. You get a pack teardown, and new CATL cells. Range goes to 400km~.

That is very cool! I can see myself keeping this car for a long time. It's just so well built and the interior is also something to behold (compared to a lot of cars). Range is not an issue at the moment (we have a Land Cruiser for longer trips) but once the batteries get really old this would be a great option.
