Interesting, I would have thought the ability to coast downhill would more than make up for an uphill drive. Interesting point there.

So I guess it was a combination of wind & elevation.

For what it's worth my daily commute I only (yes only) get 40 mpg out of my Geo Metro, but I have 3 very deep, very steep valleys that I have to go through. If I go the other direction to the city we do most of our shopping in I would guess I could easily pull 50 mpg as it's all flat as a board except for one spot it goes under a railroad.
