Cheyenne, WY to Lincoln, NB downhill with a tailwind we peaked at 55 mpg. More normal is 38 mpg and that is round trip (Yakima to Seattle) over a some rolling hills that go from 1200' to 2600' several times and then over Snoqualmie Pass at 3000+ and down to 50'. The Precis would do better but I don't fit.
I suspect that there is a way to disable the electrics and fall back to living with the 2.8 L gas engine. Time will tell.
