OmegaVX: On miles per gallon for the Prius I'm going by what people on the priuschat.com website have been posting as their real world experience. For the Trooper, I'm going by what my real-world experience is with my 2000 Trooper. For my Buell, I'm going by real-world as well.

Trooper: EPA Rated 15 City, 19 Hwy. I'm getting: 15 overall.
Buell: EPA Rated 48 City, 65 Hwy. I'm getting: 45 overall.
Prius: EPA Rated 60 City, 52 Hwy. I'm expecting: 48 overall.

Again, some folks with their Prii (plural of Prius) are actually beating EPA from time to time; but they drive like little old ladies. I like power, and the electric motor delivers, but at the expense of some of the efficiency. I also like to run the air conditioning, ordered the rear wiper (adds drag) ordered side airbags (adds weight), I weigh 245 lbs (added weight) and will frequently drive with the windows down, all factors that contribute to less than optimum. Still, beating my bike in MPG's in a powerful mid-size car that rides well and crashes well will be way cool.
