Is anyone really surprised by these results?
Everyone talked about and hyped up the F-150 ecoboost claiming that it change the 1/2 ton market by offering substantially better fuel economy...real world results proved otherwise.
Everyone talked up the Ranger ecoboost, some even claiming that it would offer "diesel-like" fuel economy but with cheaper operating costs...turns out that it gets about the same as the other midsized gasoline trucks, and much worse than the diesel Colorado.
I'm starting to see a trend here...
The overseas diesel trucks (Hilux, Colorado, Ranger) have absolutely no problem achieving +30mpg on the highway. The North American Colorado offers similar results. The only way North American companies are going to substantially improve truck and SUV efficiency is by continuing to optimize diesel or by developing some reliable hybrid options. Because so far, the "highly advanced" gasoline designs have been underwhelming from what I've seen of them.
