For reference only. YMMV, or YRMV. I frequently travel between Loomis, CA and Carmel-by-the-Sea, CA, and the one way trip is 211 miles. My S85D usually makes the trip with 25 miles of remaining range, but it has been as low as 6 miles. It’s been a great car, and, with 43,830 miles on the clock, it still charges from 260-265 miles at 100% (down from the original 270 miles). I’ve charged it to 100% more times than I can remember (approximately 2-4 times a month for the past 32 months), so I’m not sure about all those dire warnings of battery degradation. More relevant to this forum, I took delivery of an M3 AWD on Tuesday, August 28th (18” with Aeros). I went back and forth about RWD vs. AWD because range is really important to me. I ultimately decided to take a chance on the AWD. I charged the M3 to 90% this morning, which was 279 miles of range. By the time I left my house, the range was at 278. I then drove non-stop to Carmel. A/C was on and set to 4. Music was on. The total trip was 211 miles: 3 miles were on surface streets, and 208 miles were on highways (for locals: highway 80 west; 680; 101 south; 156; and 1 south to Ocean Ave.). Total travel time: 3 hours, 17 minutes. Elevation change between Loomis and Carmel: -220 feet. I used a mix of Autopilot, adaptive cruise control, and regular one pedal driving. Autopilot and adaptive cruise were set to 72 mph. I was able to maintain 72 mph for most of the trip, with the notable exceptions of an 11 minute stop and go stretch near Gilroy, CA and a 4 mile long 55 mph stretch of highway 156 (between 101 and 1). Remaining range at arrival in Carmel: 74 miles.
