It is amazing how far Tesla has moved the yardstick on electric vehicles. What I find curious is how the world's existing manufacturers couldn't generate anywhere near the range that Tesla gets out of it's battery packs. Especially since they are using laptop batteries that are already mass produced. As I understand it, all Tesla did was find the most efficient way to configure them and then manage the temperature and environment of the batteries within the pack. I'm sure there are a few other aspects that differentiate Tesla's battery pack but it's not like they created some new type of battery. They just figured out how to get the most out of them. And they had a fraction of the r/d staff and $ to figure it out compared to the existing manufacturers.
That being said, will the other manufacturers be able to replicate the Tesla's range within a few years? I hope not, I'd like to see Tesla stay on the cutting edge.
