Honda is prioritizing peppy over MPG in the Fit, the 09s have an even shorter highway gearing than the 07-08.

--Begin real math--
07-08:
5th: 0.757
Final: 4.294
3.25 engine revs per axle rotation in 07-08

09:
5th: 0.727
Final: 4.62
3.36 engine revs per axle rotation in 09.

So the 09s are revving 3.3% higher than the 07-08, and get only 93.5% of the combined fuel economy of the 07-08
--End real math--

If I extrapolate, then the 2039 fit will probably get around 9 MPG and be at 7613 RPM on the highway.
Check the Sport trie size '08 to '09
