I have a 2018 75D, the full charge range on the display on day 1 was 231 and 227 now. This is not the EPA range, its a calculated, estimated range by the battery management system.
I drive south through Oregon a few times a year and find I can make it about 240 miles driving on I5 at 5 mph over or less. That's the EPA range and I dont think its actually changed much.
I got tired of thinking about miles and just use the percent charged display. I always stop at the same superchargers on the way, miles don't really matter.
