I did an evtripplanner.com check and it appears to require only 226 Range miles at 72F to make the 237 actual miles at the speed limit. I'm considering using this route to get to I-40 from Tucson since it's considerably shorter distance wise. Anybody made that run in an S85 yet w/o stopping to charge somewhere along the way? If I go through Flagstaff it requires supercharger stops in Casa Grande, Cordes Lakes and Flagstaff, and it's about 350 miles and 404 RM which is considerably more.. I've also looked into going via Payson, it's little shorter than through Flagstaff, but it does have a charger in Payson.. If you've done the trip from Tucson to Holbrook which route did you take and what was your experience?
