So I finished my first tank of gas and the first half of it I didn't know how to drive the car and I was avg. 37 mpg. When it was all said and done I managed to get the car up to 41 mpg with 498 miles. It said I had 25 miles left in the tank so I probably could've gotten another 40 miles between gas and ev miles.
Second tank is halfway done and I'm getting 45.7 mpg so far.
I think I might be able to hit the magic 600 miles mark with this tank.
