I went with the PHEV, it seems to get about the same MPG on long highway trips, but those trips around town are a lot less costly. If you make frequent trips of less than 35 miles round trip around town, the plug in will be your best bet. It even comes with a level 1 charger which works well for me when away from home. I have an EV6 also and use the level 2 charger at home.
