My range experience is somewhat similar to yours, epirali (maybe because we live in the same area). Drove 95 miles on Saturday to Winchester, VA (20" wheels, low 90s temp, elevation change from 50' to about 2000' and down to 900', 20% of drive between 35-45 mph and the rest mostly with the ACC set to 75 mph) and made it with 55% battery remaining. Drove back a different route (80 miles and speeds averaging 75 mph for most of the drive except the last 10 miles when I drove between 35-40 mph) and made it back home with 22% battery remaining. By my calculation that gives me a range of 211 miles for the first trip profile and a range of 242 miles for the second. That falls right about in line with what I see for my daily commute 220-230 mile range.
