After one month my Sportage PHEV calculated 197 MPG (that's right) using only 1/4 tank of gas and traveling over 550 miles. Crazy! On the other hand, I have only driven in my local area and usually in EV mode. Also, our electric company, Commonwealth Edison, is rebating me the $1,700 cost of installing a Level2 (240v) charger in my garage. I tell my wife we will save the cost of the car in only 30 years of usage.
