I had mentioned power seats since I bought the cheaper package in Canada without the leather, moonroof, seat heaters and passenger power seats. Only the heated seats interested me. I also took some solstice in the weight reduction improving FE. I've heard often heard higher weight differences than 20lbs vs power and non power seats. I'm glad to hear that it's probably so little. - I won't feel so guilty for having power seats on the driver side. - Still and extra ~20lb over 300 000 km x 100 000 of these cars on the road does affect the environ. All of our luxury items and safety devices sure does chew up the FE. I won't be ripping out my 7 air bags any day soon to improve FE!

I would be interested in seeing a hycam that had the stock bucket seats taken out and replaced with ultra light racing seats though. - maybe ~100lbs could be shed?
