I found this article today. Personally I can't stand too much of what the guys at Edmund's have to say a lot of the time.
Still, it is interesting reading but with somewhat poor results IMO. I suppose they do drive their cars like ordinary people do, not like some of the extraordinary individuals here.
In short - they put a Prius, a VW diesel, a Smart and a Focus up against each other. When you throw in a hybrid and a diesel into the mix - it's apples and oranges. With the hybrid and diesel they should of blown the smart and the Focus out of the water.
I think maybe they threw in the Focus as an example of what NOT to buy if you're serious about FE. There are a bunch of folks who can't think past a Taurus, and if they really, really stretch themselves they may think of a Focus. This would be to make them think a little harder, maybe...
