More worries! S 75D 2 days old charges to 251mi not 259.

Still would not want to primarily rely on DC fast charging of course since that can do a number on your battery, too, I know. But still it would be nice to have more options since with EVs right now -- "it's not the odds, it's the stakes".
Yes, you are going thru what I went thru anyway. Note that in v6, the IC was different and actually in the center, you had your battery displayed much bigger, making it almost the sole focus point. I guess Tesla understood that as their SuC and DeC network grew large enough, they could reduce it in size and just leave it in a corner, as to not draw so much attention to it. Not that it’s not necessary info, but likelyhood of running out of juice was very low.

CHAdeMO was also on my shopping list, but in the end, the SuC and public level 2 network is plenty for me.
It is quite an expensive piece. But depends on CHAdeMO network around your trips.

Tesla has confirmed they will propose a CCS adapter. Tesla confirms Model 3 is getting a CCS plug in Europe, adapter coming for Model S and Model X

From reading TMC and understanding various charging patterns, I’m convinced SuC only might have a very small negative impact, but only on the very long run. There used to be indeed 90 batteries being limited in SuC charging speed, but I have not read any such thing for the newest 75 and 100. (Nor for the 70 or 85 btw).
 
Best bit of early advice I took was switching from miles to % on the IC. Miles are so misleading. If I’m doing a journey, even if I know the route I still use the Nav as it gives an accurate prediction of the energy use, and takes elevation into account.

I also have an S75D, and for a rough safe “in my head” calculation I take the % battery, double it and that’s my rough range.

You’re going to love it - especially in that colour :)
 
Have a 2 year old 75D with about 25K miles on it. Originally charged to 228 at 90%, now charges to 222 at 90%. Still gets me everywhere I want to go without issues. Never super charged on it yet. During the winter, I wish I had a 100D, but the price increase was just too out of proportion for the increased range. As I’m on the east coast, what I really want to see is a Super Charger at every Wawa, lol.
 
@D.E. - Have you had your S75D since 2016? (or earlier?) Have you ever been in a situation where you really really wished you had gone 90D or 100D? (I'm sure most people do at some points.)


I have never regretted the 75 battery choice. I’ve taken several trips. The superchargers are well spaced. If I’d gone with the 100 battery, I could usually eliminate one stop on a trip. But $20,000 is a lot to eliminate an occasional stop. The 100 operates at a higher voltage, the car would accelerate a little quicker and it would charge a bit quicker. I’m too cheap to spend that much for the small increment in performance and convenience. If I’d budgeted the extra $20K, I’d still sooner buy the 75 and give the other $20K to a school, a charity, or pay off part of the kids house mortgages, or put it toward the grandson’s education. That $20K would do a lot more good there than it would saving me an occasional stop on an occasional trip. As for the performance, mine has enough, plenty really. I get a thrill every time I do a full acceleration start or floor it while driving. Would I get more thrill with the other battery? Yup. $20K worth? Nope.

I am juvenile enough to want the car that out accelerates anything else. The SP100D 0-60 in 2.3 seconds or so. I’d love that. But I’m mature enough to look at the money and see where it will do more good. Don’t get me wrong, I certainly don’t criticize anyone else for their choices, more power to them. Of them, I’m jealous, just not $60,000 worth of jealous.

One issue for the OP is that he will be starting from a mountain top.

If he charges up to 100% for his journey he will not have regeneration available to him until he gets to the bottom of the mountain. The regen juice needs a place to go and with a full charge the battery is already fully topped off.

From his post, a good option would be to start at 90%. Use the regen available to make his down the mountain trip efficient and enjoyable. Then get enough juice from the Supercharger on his way home to arrive safely with a nice margin of range.

I guess I'm going through what most new EV owners do... staring at that range meter all the time. If you're saying you used to do it, but don't anymore -- and that the concern goes away with time, that's actually really good to hear. :) Maybe I'm just going through a normal 'new Tesla owner range watching phase"...

And you're right... Never did do anything like that with an ICE; (Though when I got my first hybrid I do admit that I did hypermile like crazy and try to get that MPG up --- for a while. Then I just drove the thing. :) )

I think really a whole lot of this will be less of a big deal when charging stations are more plentiful and it can be an "Oh I'm getting low, gotta stop for a charge" sort of thing. (supercharger and other; I did order the CHAdeMO adapter... (maybe someday Tesla will ship it!) - and hope that they do come out with a CCS adapter... even though it seems that a CCS adapter is not in the cards.)

Still would not want to primarily rely on DC fast charging of course since that can do a number on your battery, too, I know. But still it would be nice to have more options since with EVs right now -- "it's not the odds, it's the stakes".

For what it's worth, my 2016 Model S 75D used to charge to 259 miles at 100% but my 2018 Model S 75D only charges to 249 miles. Like others have stated, it is just a best guess and your mileage will most definitely vary. It's all relative and there is nothing wrong with your battery. Enjoy your new baby and have a blast learning what it is truly capable of! ;)
 
Interesting to hear ranges on the 75. Almost makes me jealous. I have a 13 month old showroom 75 with about 10k miles and my 90% is 213. Not complaining per se, but seeing these numbers in this thread makes me think I'm doing something wrong. I charge to 90% in the winter and 80% other times. I do pre-heat often and supercharge maybe 3 times a month. Wonder if the battery was somewhat degraded in the showroom?
