This is my 4th tank of gas since March 5th, averaging 80.7MPG on a 10.2 Gallon. Everything else stayed the same as before, the only thing I noticed that was improving my MPG this month was the Temperature was 7 degrees higher, Morning averaging from 70-77F and on the way home averaging from 77-85F. Model: Four Touring 2016 Silver Drive Mode: Normal Tires: 42PSi Front, 40PSI Rear
Wow. The extra surprise is that (presumably) you have the gas hungrier 17 inch tires that comes with the Touring model.
I am with bisco. Seeing the display set to show the EV driving percentage and the average speed would be very enlightening. LIke this . . . Don't take the MPG seriously here, that was all down hill. No way where I live could I get even 70 consistently.
