MPG Hypothetical Comparison

[staryoshi]

Trying to approximate this hypothetical comparison, but cannot drive to test...

At 60 MPH on country roads, about how would the Ranger and the F-150 with the 2.7 stack up? Both 2021 4x4 models, no off-road/performance-affecting packages.

Any insight?
Thanks.

F-150 will win if it is geared high and unloaded.

That's kind of what I'm thinking due to the aerodynamics of the two. It's gonna be a daily driver for about a 60 mile round trip in the sticks.

You will never make up the price difference between a Ranger and F150 in gas cost savings.

If you’re trying to save money, total operating cost per mile, or total operating cost per year, are better measures than MPG. Comparably equipped, doing the same work, I would bet on the F150 being significantly more expensive than the Ranger.

A quick Google search tells me that both the Ranger and F-150 share the exact same gear ratios. As best I can tell the 2.7 comes with a 3:55 or 3:73 rear-end ratio. For the sake of the discussion, let's say you option with the 3:73, the same as the Ranger.

Edit: Forgot to finish my thought.

The two engines will run the same rpm at the same speed.

Gotta imagine the 6cyl will take more fuel to do so.

Plus the F-150 is heavier.

Ranger wins.

A 4x4 F150 with the 2.7 has and EPA rating of 19/24 and a 4x4 Ranger is 20/24. It’s not going to be enough of a difference to be a deciding factor.

6 cylinder has different fuel injection and turbos. F-150 is only about 400 lbs more. I’ve driven both. F-150 gets better mileage.

tire size will change RPM, as well as Coefficient of drag affecting MPG.

In the real world. Definitely possible.

But the OP is asking ONLY about a hypothetical situation driving 2 trucks down the same road at a constant speed.

Of course the 2.7 will use less fuel to accelerate at the same rate. Of course given real scenarios, one might get better gas mileage out if the F-150. Either way the difference is very much insignificant.

The 2.7 fuel injection system only adds multi-port to the direct port injection for longevity.

True, forgot to include tire size in my hypothesis.

Regardless, that's enough thinking about a hypothetical situation for a hypothetical truck purchase for me.

The discussion has been useful for me so far, thanks. Struggling deciding between a SuperCrew Ranger and a Supercab F-150.

I won't get too deep into my conundrum, but they're closer in price than I would like and the F-150 feels much more current, but the Ranger is better-sized for my needs. Making up the difference in price via fuel economy isn't my objective... But balancing efficiency/utility is important to me.

Again, I appreciate the help thus far, I have weird priorities...

I can get very exact in what I'm comparing if anyone wants to go down that rabbit hole btw
