I would be interested in a get-together, or even an MPG challenge. However, I'm not really interested in doing the Pikes Peak Hill Climb. I think the numbers from this drive would be well below the EPA numbers and would not "showcase" what a hybrid could do. To beat the EPA numbers on hills, you need the grade to be such that during the downhill portion, the terminal velocity is slow enough to be safe. Otherwise, you are just throwing a lot away by braking (including engine braking). I imagine everybody's battery packs would be topped off in no time.

Another way to look at it: To beat the EPA on a round trip up and down a mountain, you have to get at least half of EPA on the way up. If you get half of EPA on the way up and you use absolutely no gas on the way down, you will be at the EPA number. You can imagine that if you keep increasing the grade, you will reach a point where half of EPA is not attainable on the way up. I believe the Pikes Peak road is that steep.

I just don't see a lot of room for hypermiling techniques on a drive like that. Anyway, just my opinion...
