Some of seem to confuse issues when discussing Model 3 features, performance and pricing.
First, Elon, JB and every other source confirm that the Model 3 is built for simplicity, including the open roof along production line allowing the interior to be robotically assembled, then the top dropped in place. That, and myriad other things speak to engineering for manufacturing ease and consistency. All of that speaks to the single display pod but says zero about HUD because HUD is easy to install. We need to think about manufacturing ease, not user features, when discussing Model 3. Software enabled features could be simply amazing, so long as manufacturing stays "easy" meaning machines can do it. QC improves with manufacturing ease too.
Second, features are likely to be surprising to most of us because most of them will be delivered via only software or by simple to install models. Either way almost all features that will be optional will be either software-based or modular so they can be essentially 'plug and play'.
Third, performance will be better than simplistic extrapolations of battery size imply. Remember this is a true third generation Tesla with entirely new architecture and packaging. There will be a wide range of options, some of which will come with later offerings. Either way the "P" versions will at least match the SP100D in most relevant measures but with <25% better wh/distance.
Fourth, the everlasting debates about pricing will be resolved because the range with be ~$35,000 starting to ~$90,000 or even ~$100,000. Thus the Model 3 range will be similar to that of the S and X, the BMW, MB etc ranges. Just as with all these cars that wide range will accommodate a vast array of dramatically different tastes and budgets.
Lastly, repetitive though it is, the innovation above all others for Model 3 is in manufacturing ease and consequent ease of installing options while maintaining high build quality. They'll certainly have an array of aftermarket upgrades available for buyers who desire them. That will improve everyone's results, buyers and Tesla's.
Nothing I just said is really new, but most of our discussions imagine that the Model 3 will e just like other cars. It won't.
Some might think me too optimistic. Not so. This approach will
test the living daylights out of suppliers. It is almost unprecedented. It should be better and simpler. I hope it will be. I'm betting it will be.
