Well nobody ever replied to my Honda Fit thread in the first place, so I'll just bring it back since it was just put up against 6 other $15,000 hatchbacks in the May 2006 issue of Car and Driver magazine. Now obviously if you want the full review, you'll just have to buy the magazine (or search the websites with a lot less respect for copyrights) but I'll clue you all in on the FE numbers:

Name/Displacement/C&D's observed FE over 1000 miles:
Toyota Yaris 1.5: 36
Honda Fit 1.5: 35
Hyundai Accent 1.6: 30
Kia Rio5 1.6: 30
Nissan Versa 1.8: 28
Suzuki Reno 2.0: 28
Dodge Caliber 1.8: 28

Now knowing that this is the same Car and Driver that typically knows only two throttle positions (full throttle and off throttle), the fact that the Fit and Yaris did so well bodes very well for these two new-to-the-USA entries. The fact that they both SMOKED everyone else shows the sheer dominance Toyota and Honda have over everyone else when it comes to fuel economy in the real world.

As a final note, I will point out that Car and Driver ranked the Fit much, much higher than the Yaris on the basis of it's handling and fun-to-drive scores. What can I say, as a previous owner of one, I love Honda's hatchbacks and this great result for Honda brought a smile to my face.
