It's that curb weight value that I find annoying/disturbing.

I mean, I could probably design a vehicle that gets 50mpg and weighs 4
tons. (it would accelerate worse than a tortoise, but that'd be the
price for good fuel economy). And according to their parameters it
wouldn't be "greener" than a vehicle getting 20mpg.
