[...] Accenture, which surveyed 1,850 consumers in North America as well as Germany, France and Italy, notes that just over a third of the respondents (36 percent) named higher gas prices as a reason to purchase a greener car. Responses from participants who have driven a hybrid or electric vehicle (EV) suggest today’s green car makers need to step up their game in order to really impress consumers on factors beyond fuel economy.

I’m throwing an idea out there for a new way to do ratings as you suggested in your article. The basis is measuring how many miles a car does per $ spent on fuel. Its a method with limitations I know, but consider for a second the positives: Its simple, universal, easy for consumers to understand & its not subjective so there can be no gaming or influencing of the figures. Let me know what you think:

Corporate honesty has just gone out the window… It’s no wonder that GM went bankrupt and nobody trusts them… Doing a little math of my own, it looks like they did the 51 miles on around a quarter gallon of gas. That means the “real” MPG is around 40-50 MPG. Pretty good, but not even as good as the Prius.

I’ve got a pickup truck that will get 17 MPG… However, if I tow it for 40 miles, and run it for 11, then I come up with about 80 MPG… That’s pretty much the same thing that GM is doing… Lying bastards!

cliff,

Who are you talking to, me, Walter, or CSX?

Whatever, CSX did the math. I heard the same ad that Walter is quoting. Is it wrong?

The coal train I recently saw in Kansas City had 6 BNSF locomotives pulling it, not that that matters in the present discussion. It was just amazing. It certainly brings home the fact that coal is the base of our electricity system. I heard that KCPL uses two such train loads every day -- Could this be true?

have you somehow forgotten the mile long load of coal cars 2 locomotives can pull?

you might want to do a bit of math before you go and say something is absurd.

csx spent 185million on fuel in the second Q, now go find their 2q freight tonnage and do the math.

Re Walter Thompson,

As a train gets larger, the air drag per ton of freight goes lower and lower. So rolling resistance is the main energy loss for the vehicle itself, not counting engine heat discharged. Since steel wheels benefit from about .001 for their rolling resistance factor compared with rubber wheels that have .01 rolling resistance factor, this 430 miles for a ton of freight per gallon sort of compares to 43 miles per gallon for a one ton car.
