Used two and a half gallons of gas and got a bit better than 60 MPG for the 150-ish mile drive. I forgot to snap a pic to give me exact numbers, and now that I've charged the car, that info is lost... or at least I don't know where to get it once the display has reset.
On the way to Redlands, I put the car in Mountain mode when I got around 15 miles of range on the battery. That way I could drive around Redlands on battery instead of in extended range mode. On the way home I just left it in Normal mode the whole way.
