I am many, many hours into researching a Model S. I've driven one at the Scottsdale galleria. I have checked out evtripplanner very carefully. I know that the Cordes Junction supercharger will go live before I would ever take delivery of a Model S. I'd like feedback on the feasibility of the following: I work at Phoenix Sky Harbor Airport. From Mid May to late September I live in Flagstaff. The driving distance to KPHX is 151 miles, so 300 round trip. The net altitude change is just over 6000' (evtripplanner knows this). I want to be able to leave Flag with a range charge, drive carefully to KPHX, be gone for a 4 day trip, returning on the evening of day 4. I am fine with stopping at the soon-to-be-opened Cordes Junction supercharger for a top-off. It's 85 miles from Cordes to the Flag house, so I would charge to about 130-140 miles range to account for the big climb out of the Verde Valley, and the slow uphill after that. I am NOT OK with having to charge the car to get to Cordes Junction from the airport. evtripplanner shows this for Flagstaff-KPHX-Cordes Junction:riving Time3:32Total Energy Used69.7 kWh 249 RMAverage Efficiency299 Wh/mileNet Elevation Change-3375 feetIs this enough reserve? I really don't want to have to stop at, say, Anthem, and use a Blink charger to get to the Cordes Supercharger! I'm willing to incur the Supercharger stop, but not that PLUS a J1772 stop right after leaving KPHX. Yes, there are two Blink chargers at Terminal 4, but I have to park in employee parking, and those lots don't have chargers. Is my plan to do FLG-KPHX-Cordes Supercharger realistic?
