That's some nice click bait you posted, McRat! :wink2: Glad to hear what's theoretically possible, even if unrealistic. With recent 'uncompromised' speed (75-80 mph) open highway travel, in Comfort mode with typical radio, HVAC, and seat warmer use (yeah, I like it even in 70-degree FL weather), oh-and iPhone charging as I'm accustomed to doing, I'm seeing range dip in mid- high-180s, or about a 20% drop from 'advertised' figure. Again, I'm pushing it on speed (plenty of time spent at 75+) not 'trying' to achieve anything (good or bad), just seeing what normal driving behavior and settings will achieve. SFLGator and Electro previously reported seeing highway range in the 190s, presumably without seat warmers/device charging, so pretty consistent with my results. Anyone else seeing better or worse under long and normal speed (75+mph) open highway mileage? Next long (100+mi) trip I might try optimizing (Eco mode, no HVAC or seat warmers, no charging devices, regen OFF (vs. low) etc.) to see what's possible in more efficient (but not hypermiling) long haul conditions.
