March 2017 build S75D.
Brand new:
100% - 260 miles, once, but more typically 258/259 miles.
90% - 233 miles.
Today:
Mileage - 41,000 miles
100% - 244 miles
90%. - 219 miles
I charge to 100% at home about three or four times a month, then charge at a supercharger for the return trip home to about 90%, also three or four times a month.
I've been pretty hard on the battery, I'd have to say.
