2018 M3 LR+ with 60,000 miles and 19" wheels. 100% SoC shows range of 285 miles. If I did 55mph on the freeway (like I had to before I had supercharging set up), I can get close to one actual mile per one stated mile. 80mph on the highway, I might get 180 miles from 100 to 0 SoC.
Since most superchargers are 100-150 miles apart, I'd have to stop anyway. So, it's not a big bother, usually. Stretches like Springfield, MO to Little Rock, AR is a danger zone with the highway range I have and I would have to go from 100 to 0 SoC. (TESLA, PLEASE GET A SUPERCHARGER IN BRANSON, MO or northern AR!) But it'd definitely be nice if:
- Superchargers or fast charging in general was as common as gas stations so we can run down all the stated miles if we wanted. I think this is the best answer for all involved. Or...
- Get closer to the stated miles so we might have the option to skip some chargers if we want to. I heard that the Porsche Taycan displays the worst case highway miles, and as you drive in mixed conditions, it just gets better as you gain range (or don't lose it). That's why their reported mpge is so low. That's pretty neat. Or...
- Larger, more efficient batteries. If Tesla's new batteries are cheaper, denser, and more efficient, perhaps we can get closer to the 400 miles range mix so we can get 300 miles of highway range. Unnecessary 99% of the time but would be nice.
