To provide a bit of balance against all these threads that start with, “Hey, I’m not getting the range that Tesla promised me...” I’ve owned a 2019 M3SR+ for about a year now. I’ve got just under 10,000 miles. It is my daily commute car and we use it for trips to our daughter’s house - about 60 miles each way from the distant southeast Philly suburbs to the northeast suburbs (except during the pandemic, when we couldn’t drive through Delaware - that made it 66 miles). Most of the drive is on I-95. In my daily commute (32 miles round trip) during non-winter weather (see below) the battery meter matches my odometer to within +/- 1 mile. In most of my longer trips, the number of odometer miles I drive exceeds the amount that comes off the range estimate. My energy graph almost always projects more range, also. Even with the AC running and driving 65 we are below 200 Wh/mi. On a recent beach day trip (about 200 miles round-trip) our battery meter decreased from 209 mi (I don’t charge to 100% even for trips) to 69 mi with a 20-mile boost at a supercharger mid-trip for a bigger safety margin in case there was bad traffic on the way home. Basically that’s a 160 mile consumption of estimated range from the “Guessometer” for a 200 mile trip (nominally 196 miles, but I had to go several miles off-route for the supercharger and made a wrong turn that required back-tracking). Our 130-mile trips to the northeast burbs usually consume slightly less than odometer miles (maybe 20 miles less than Guessometer miles). In the colder months (December - March) I do see range reduced by roughly 30%, but May to October I beat the battery indicator estimate and in June - September I crush it.
If you take lots of very short trips with no pre-trip charge your battery is not warmed to ideal temp and you are more likely to see lower range if you add up lots of small trips in your stats. For short trips who cares - they are short (no challenge) and you can top off when you get home. Longer trips are the sweet spot - you need more range but you get better range because of battery warming (more efficient regen, etc.). Apartment and townhome dwellers with no garage/home-charging who also make lots of short trips are, unfortunately, the worst-case scenario. Well, actually, people who live near the arctic circle are the worst case, but no-home-charging-with-short-commute folks are the second-to-worst case.
