Love that graphic you included of the elevation!! I have found that the Navigation App seems to estimate things quite accurately so far, and lots of times I use even a bit less energy as I try to "drive nicely" and be conservative. I drove part way through the Tioga a yesterday just to get a feel of the energy burn... it did seem to be pretty accurate, and I was giddy seeing all the REGEN happening when I turned around to head back. I had the afternoon free and decided to take my MS on a road trip. I didn't have time to do the full stretch, but I lived in Missouri long enough that I still live by the motto: "SHOW ME!" Things are looking up for the MS85 trip over Tioga. Thanks to everyone who has chimed in and given me the benefit of their experience and wisdom!!
