ECO Mode Works! 241 mi range on a long day trip...
On the basis of a couple of airport round trips (120mi) at high speed (75-80mph) and in Comfort mode with HVAC, seat heaters, etc. used liberally, I had come to the conclusion my highway range was in the 180mi vicinity. :-(
Today I had to travel to a distant (~90mi) city, so I had my first 'range anxiety' about the round trip without a charge. I charged to 100% overnight; the car read 214 mi range (I've been doing more highway driving lately). On the way there I took a mix of local roads (45-55mph), not just for range, but because I had other stops. I avoided the racetrack starts the car usually encourages me to enjoy, and reached my destination, 87 miles away, with a range of 150 still on the gauge! This was the first time my ACTUAL mileage (87mi) exceeded my GoM CONSUMED mileage (214-150=64mi).
After scouting out a couple sites nearby (about another 10 mi of driving), I took all freeway back home (95mi trip), again staying in ECO mode, speed at 65-70. I used AC about 1/3 of the time (I noticed as I set out it reduced range by 15 mi on the GoM), but did not use seat heaters/coolers. Also charged my phone and used the radio most of the way back.
Bottom line, I got home with 50mi of range left! The total drive was 86+10+95=191 mi and yet I had 50mi range left. Very happy with this 'new math'. ECO mode rocks when optimal range is needed! (and the GoM adjusted: I 'used' 100mi on the GoM (150-50) to go an actual 97mi taking the freeway back)
