Yeah, the distance is 199.2 miles between Burlington and Glen Allen Superchargers. I did it in 60-65 degree weather at 325 Wh/mi averaging 66 mph, which involved driving 75+ mph for big stretches of time. I did a range charge the first time, and didn't bother with a range charge the second. The big problem is that if you miscalculate and leave too early, then there aren't many good options to add charge. On my way back from Burlington, I only put in 68 kWh or so, so it was a bit tight. I did the 203 miles back to my house using 316 Wh/mi by driving slower in I-85 (68mph) and then driving normal in I-95.
177 miles isn't bad. It's possible to charge to 80% (212 ideal miles), use 375 watts/mile (driving 75 mph + heater) and hit that range. But it's right on the cusp of that. Therefore on an 85, one still has to wait longer to into the charge rate tapering to be comfortable and drive "normal." For 60kWh owners, this is probably deep into a range charge, which means a much longer time at the supercharger before heading out, or drive below speed limit - basically, you have to use probably less than 325 Wh/mi.
There is NO WAY my 60 could do 177 miles between SC. At 325 wh/mi it would take very ion out of my battery. Furthermore my RR has dropped significantly now and driving at highway speeds, even as low as 65 I am getting only about 88% of the RR. My std charge is around 173 at this point which means I can comfortably go about 150 miles at 65mph. So hopefully they will keep the SC within 140 miles of each other.
