Three times in three years, I have achieved 30+ MPG on a single leg of a road trip (highest was 31.5): each time, this was a leg that trended down in elevation and with no headwinds. Most of the time on a road trip, a leg (I mean between fueling stops) averages c. 25 MPG. When I gas up, at those MPG figures the Range shows either side of 350 miles. I think I saw nearly 380 on that singular occasion of 31.5 MPG, but I could be misremembering on the high side. I do know that once on here, not long ago, one of us claimed to see over 400 Range after a fill up: now, that I'd have to see to believe (not that it didn't happen: but HOW - what factors - did that happen?).
