MY2013 Ford Fusion Titanium Hybrid Fuel Economy vs. Speed

The results are in. Just finished doing more fuel economy tests with my 2013 Ford Fusion Titanium Hybrid. There is the master equation. Same stretch of road - on ON-401 to French Line and back. First time I ran the test, I was doing 120 km/h, then on the way back, 110. This time, 100 km/h outbound, 90 km/h on the return. It was also interesting to note that even though I haven't updated the powertrain control module (PCM) firmware yet that allows the electric motor to run at speeds upto 85 mph, even at 55 mph, it still wouldn't kick over into electric mode and cycle through. I thought that was interesting because I had expected that it would, but with the cruise control set at even 55 mph and holding it constant, it wouldn't kick over.
