High speed High capacity High voltage? High power charging? High gear? High range? There's a lot of discussion about the performance numbers and top speed, but I don't really care about that. The next key step for EVs is to push charging to its limits. Also, increasing the range to make it _really_ match other cars. In addition to that, there's making them performance cars (although that's not really important for Tesla's mission). It seems that the Roadster Gen 2 will attempt to check all the remaining boxes.
