Currently I have gone 1,900 miles and still have over 1/2 a tank of gas. I may go 5,000 miles on a single tank of gas (7 gallon tank). Mileage is incredible. I plug in a work for free so electricity cost is low. It usually costs $1.40 cents to charge at home and I can travel 50-60 miles per charge. My daily work commute is 56 miles and I make it 99% of the time on all electric. The gas motor will turn on if the battery is fully charged and then you apply regenerative brakes, thus overcharging the batteries. To prevent this Honda reduces regen and turns on the motor. To avoid this just use the brakes, no regen, for about a mile. I love this car. It is quiet, big, fast enough, and gets crazy gas mileage. I own a Volt, but the Clarity PHEV is better in most ways.
