What MPGs does the 2015 Toyota Tacoma Double Cab V6 4×4 get on the highway? How does high elevation affect fuel economy? Would it be a number that is better or worse than the EPA rating? TFLtruck finds out here.
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. Here are the details.
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 43.6 miles.
Once we merge onto the highway and set the cruise control at 65 mph – the run is a 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 was one person in the truck and a set of camera equipment. The outside temperature was 45F with a slight wind from the west.
The EPA rates this Tacoma Double Cab 4×4 with the 4.0LV6 at 21 MPG on the highway. The results are surprising. Watch the TFLtruck video to get all the details about this real-world test.
