I am contemplating driving from the east coast to Phoenix, AZ around the end of August, beginning of September. Currently there is a supercharger gap on I-10 between El Paso, TX and Casa Grande, AZ. Can people familiar with this route please suggest the best (quickest) places to stop and charge my car, which is a 2013 P85. I don't know what the speed limits are along the road and what the elevations are. When charged to 100%, my car indicates a 256 mile range (I have never achieved this range). However, based on speed, elevation, wind, rain, etc, I normally plan for no more than a 210 mile range (I like to have a reserve just in case). I average about 343 Whr/mile. Thanks.
