I got my best trip average so far - 5.4 m/kwh. The route was mostly urban with a few miles on the freeway. As always involved quite a bit of elevation changes. The temperature near home was 77, probably 80 elsewhere - but didn't use the AC (but the window was open). I've done similar routes before - couple of weeks back when the temperature was 52, I got 5.0 m/kwh.
5.4 m/kwh would be like 115 miles of range on 100% charge.
