I was extremely dismayed to find out that this really expensive car, purchased explicilty to be able to commute all-electric, will not run in ev-only mode in hot weather (i.e. several months of the year in Phoenix :( ). Apparently Ford didn't like putting the stress (?) on the batteries when the weather is slightly on the warm side. Haven't found the trigger point. I know it very easily switched to gas drive when the temp on the car instruments was 106. Does OK at 90. So far my commute that I'd hoped to be all-electric is coming out about half gas, half electric no matter how gently I accelerate when the temp is in the 106 range.
