Got my MY on Saturday.. totally in love with it.Yes I thought about this too and I know than Elon has recently posted about the structural battery pack coming together. My concern is when will this be delivered for the RHD UK and the build to be considered as problem free as the current China models. Even when they are shipping the 4680-equipped models there will be question of longevity and degradation, which will take a year or two to prove in the real world.
From what I read all the current MIC models have a good build quality so my dilemma is take something good now or wait for something better in the future, without knowing how long that wait will be. The typical Tesla dilemma tbh. There is certainly the possibility that I could swap cars again a few years down the line if the improvements were big enough, funds allowing, possibly even a to a non-tesla if the superchargers open up.
I do wonder how they would manage a significant change to an exiting released model, perhaps they will create a new model based on the 4680s and release that slowly around the world while still making 'standard' 2170 cars? Maybe an XLR version.
Actually my current thinking is that Tesla will not make the 4680 cars significantly different at all. Most consumers dont know\care what batteries\motors they have, they will just look at the advertised range\speed. The iPhone approach. It may save Tesla money, it may enhance the driving ride a bit, it may speed up charging time and extend the range another 50 theoretical miles, but I think it will be the gradual improvement that Tesla always does. Also they wouldn't want the MY to outperform the MX.
With all that said I've just come back from a small run out in my 2019 M3 and it still gives me all the enjoyment driving it and pride in owning it, so perhaps I should just hang on to it forever.
I thought long and hard last year because with 4860's imminent (as it then seemed) was I buying the last of the "old tech"? As it turns out 4860's are still MIA and probably won't hit these shores until the MYP gets them (early Berlin MYPs probably won't have them) and so a 4860 MYLR could be <insert wild guess here> months away.
Will Tesla pass on any of the 4860 "goodness" to the consumer - they could keep the price the same and increase the range (if say competitors start increasing their range), they could drop the price and keep the range the same or they could leave range as is and trouser the extra profit or a mix.
On the Daily Tesla podcast a week or two ago when Tesla said no new news on the "Model 2" they said there was "plenty of scope for further price reductions on existing models" - make of that what you will.
What I wouldn't want to be is the poor sod who gets his car delivered the day before the next big upgrade happens. But I'm happy the current MYLR will probably be at least 18 months before any significant change in spec... if you dont count the inclusion of a parcel shelf - damn it... had to bring that up!!
