After doing my first real road trip in the x60, I can confirm that 200 miles a charge is not realistic. I am using my leg from gustine SC to buttonwillow SC as my control: 150 miles all flat, no climate control, going 73 mph average. My first trip I got to buttonwillow from 100% to 11% (22 rated miles left). My return trip, same conditions, I had to stop at Harris Ranch in between because I was projected to arrive with 5% and dropping. I think the variable was strong headwind. Anyway I think realistic range is 170 miles under ideal conditions.
