We got our 2016, new, in late July and love it. Around town which is most of our driving we get estimated 60+ miles EV (in warm weather)by driving carefully and using the regen paddle. We occasionally take out-of-town trips of 100-200 miles, at least partially at interstate speeds and mostly along flat or moderately hilly terrain.. To maximize EV miles should we be using Mountain or Hold for the highway/interstate portions of those trips? Thank you
