It really would depend on the day. My daily commute to the office is exactly 21 miles one way. If I could charge at home and work (definitely doable) I would never need gas! Its when I have to make road trips that concerns me. I currently drive my Cherokee for work and I avg 30 mpg with it.The question is what kind of driving will you be doing ? if you have shorter trips with opportunities to charge the 4XE is a good choice. If your driving longer distances with few chances to charge it may not be.
