Not sure. Oh, wait: I think it's because they're categorized by EPA rating. Bruce's is an HX and Will's is the Si.

I have an '05 Prius and on my test run around the Lake I got 59 mpg.
I was surprized nobody beat it. In other years we had Priuses that did much better. I think the wind may have been a factor last Saturday.
