We have been driving ours since August in the northeast and our “lifetime” (mostly local, a handful of long highway road trips) has our usage at 333 Wh/mile.
We show 300 mi of range at 90% or 267 at our daily 80% set point, but of course the coldest days would eat that up. As it’s been getting warmer, we’re getting back to where we were at the end of the summer last year.
We sprung for the 100D and have had a few occasions where it really helped us - had a wedding weekend that was pretty far away with no good locations for charging. By charging to 100% en route and a little bit of driving during the wedding weekend, we still made it back to the same super charger whereas if we had the 75D, we would’ve had to alter our route by about an hour “out of the way.” It wouldn’t have been terrible, but it was a lot nicer with the extra range.
