What MPGs does the 2015 Ford F-150 2.7L EcoBoost get on the highway? How accurate is the trip computer’s fuel economy reading? We wanted to rerun our initial test with fuel-pump verification to find out.
Why do the highway fuel efficiency run? This is a test with fewest variables and least human interaction. Fill up at the gas station, get on the highway, set the cruise control, and study the results. Well, there are a few more details to it.
The route consists of a 21 mile stretch of I-25 just north of Denver, Colorado. It begins at the gas station near exit 229, then goes north to exit 250. This is where we turn around and head back south to the same gas station. The round-trip is approximately 43 miles.
Once, we are merging onto the highway, setting the cruise control at 65 mph and making the run down the relatively level stretch of highway with a few rolling hills. The elevation is just over 1 mile above sea level. We then turn around at exit 250, where there is only a stop sign, and come back to the gas station (again with cruise set to 65).
There were three people in the truck and a set of camera equipment. The outside temperature was 49F with a slight wind from the west.
The EPA rates this SuperCab Lariat 4×4 with the 2.7L EcoBoost at 23 MPG on the highway. The results are surprisingly close. Watch the TFLtruck video to get all the details about this real-world test.
