hi dave
congrats on kicking the FEH on the mpg. We drive our hihy generally 1 or 2 miles to the store. I took it on the highway once, just to help break in the engine. We have 150 miles on the car after a month, 68 being that highway trip.

on the highway, it averaged around 25 or 26 mpg. I was able to get it up to about 65mpg then coast for a spell without the engine, but it would keep trying to kick back on.

other than that, we decided the mpg we are losing in the city due to short trips is well worth the enormous savings on gas and miles on the vehicle by not driving it. We have a jeep grand cherokee limited that can get 20mpg on the highway so we use that for long trips.

overall , we are getting 22.5 mpg on the hybrid ,but after a month of owning it, it has almost a full tank still . I really cant wait until we can get the conversion kits for the optional plug in . Then our tank of gas will probably go bad before we use it all!!!!!

lol
