Maybe, but without knowing Wh/mi, you can say which car would have longer range, which is all that matters. Ie, if the 3 is much more efficient, it could have more range on a smaller battery.I posted this in a CPO thread earlier but it applies here
1. a new Model S will always have the same or higher capacity battery as the top option than a model 3
I agree with your basic premise, but I think it applies more to things like autopilot (or autopilot v2). Ludicrous mode is less "technology" in my mind, then just a realization that the limits on amp draw could be relaxed (yes, the contactor is made of different material, but I don't consider this to be significant tech)Think about that for your Ludicrous mode question. If a 2015 car has Ludicrous mode a 2018 Tesla Model 3 will have it. Whatever tech is common in 2016 will be on the Model 3 even.
To get back to the OP's point, there will be a max performance version. Whether it's called insane, ludicrous, plaid, or whatever Spaceballs reference comes next is just an arbitrary label on the particular performance buckets.
