If you think this is a promotion -- I looked up the research group that those figures came from. Here is their website:

Being non-hybrid doesn't make a different, the Honda Civic (regular) costs $2.42/mile
And that article compares the Accord Hybrid ($3.29/mile) and the regular Accord ($2.19) as well.
And here are some of the more in-depth details...from the research group. If you click on document1095 and you can see a break down of each car's cost per mile over the lifetime of the car.

I was happy to see my focus is only $.80/mile!
