I love categories. However, I think this is definitely a case where we could get too many, too soon. The issue of vehicle weight has come up several times though, and this was my first thought as well (given that most of the closest competitors in my class are a 1000+ lbs. lighter than me). I'm not sure this should be something that necessarily gets one into the top ten(s), but I am very curious about MPG/weight ratio.
For example, it often occurs to me when I see a semi rig on the highway, hauling say, half a dozen bloated Pickups/SUVs, that there is a tremendous disparity in their FE vs. weight. That is, the SUVs are getting say, 15 MPG and weigh 3,600 lbs (i.e. Jeep Liberty) while the semi truck, trailer, and load totals out at around 70,000+ lbs. and is still getting... 6 MPG (or so). That's nearly twenty times the weight, but only two and a half times the fuel... so I'm thinkin' this can be expressed in some nifty figures and would make for an interesting tool for comparison.
Just did some looking around to see what that might entail, and came across
this thread, in which we find the following, which is what I was getting at:
Curb weight w/ 200 pound driver:
Prius II: 3,090 pounds
Prius I: 2,965 pounds
HCH Manual: 2,884 pounds
Insight Manual: 2,080 pounds
Average MPG per the Real Mileage Database (this morning):
Prius II: 48.3 mpg
Prius I: 48.3 mpg
HCH Manual: 46.9 mpg
Insight Manual: 66.9 mpg
Average mpg/pound:
Honda Insight: .0322 mpg/pound
Prius I: .0163 mpg/pound
HCH: .0163 mpg/pound
Prius II: .0156 mpg/pound
