Obviously they will have bigger battery versions, faster versions, lighting/trim upgrades, etc... But the "next level" stuff will really have to be about the Auto Pilot and the Battery I think. Everything else, while nice, isnt really "disrupting" (and I know all the kids like to disrupt, these days). In fact, its kind of inevitable. I know everyone lost their *sugar* about the P100D badge image (and I get why)... But was there ever a doubt that it was coming? Its only a matter of when, really.
Its kind of odd that he mentioned it in terms of being specifically about the Model 3 (he said its Part 2 of the model 3 reveal, not just the next gen of ALL of Tesla motors cars), so that actually has me thinking that it could be something no one has any idea about...
Then again this really could just be about how much range they can get out of the biggest battery option, and how ludicrous the acceleration will be compared to other cars in its class. Given the roadster 3.0 got some impressive range, this car could really take EV range to the next level and make it the car that finally ends the discussion. 350 miles with a 10 minutes to 80% SOC would be lights out for almost any other car in its price range, why even bother with an ICE at that point?
