New F150 Powerboosts are not known for fuel mileage when towing. Many, many reports on this issue.
Every test that I have seen so far seems to have been designed to avoid taking advantage of the regen capability of the hybrid. Accordingly, the test results are roughly what should be expected from a non-hybrid doing the same test.
My experience with my two 3.5L Ecoboost engines is that they do burn more fuel than a diesel but noticeably less than my old 460 or V10. In terms of $/mi the Ecoboost is on par with the diesel at local fuel prices.
