Drove it for a year. It had General stock tires on it. Tires, wind and weight make a big difference. Hardly any engine idle hours. Was an awesome truck.
It's difficult to properly characterize since there are a lot of factors and how you drive, the conditions you drive in, etc. all tend to matter.
I'm generally pretty careful about my driving. '21 King Ranch FX4 exactly as it came from the factory - I'd guess I generally get about 20mpg around town and about 24mpg on the highway.
In the city I've gotten as low as 14 and as high as 26mpg.
On the highway I don't think I've ever gotten worse than 22 and never better than 27mpg.
If the context helps? I get about the same gas mileage around town with the PowerBoost as my wife gets with her Subaru Forester.
From a trip to the coast yesterday. I neglected to get a pic of the return trip, but iirc, it was 27.6. I wasn't hypermiling or the sort; mostly interstate at 70+ MPH and light traffic <45 MPH on local roads.
The last tank of gas netted 10.8 mpg. Of course I was towing through the VA & WV mountains. It was 8.8 when I crossed the highest point in WV. It slowly improved to 10.8 mpg by the time we reached Huntington, WV.
The fact that I can roll down the Interstate with the cruise control set at 80mph for hours and still get 20mpg has made me stop looking at it like I did 5000 miles ago when I took this pic while actually driving 80 with the cruise set lol. Please don’t do that. Keep your eyes on the road.
Permanent shell, Talon's Garage cat protector. I'm kinda disappointed. I don't drive crazy, do carry equipment here and there. Was definitely hoping to push 23mpg
I have over 11k now and the PB is capable of high twenties with certain conditions met. It loves long drives at 60mph or below with some traffic thrown in to rack up electric miles. Short high speed drives are the worst, so if you hop on a freeway for 10 minutes to work every day reported mileage will suffer.
I just finished a drive from San Diego to Long Beach and averaged 22 mpg driving at freeway speeds. Cruise was set at 77 mph. Not far off the 23 mpg that was on the sticker when I bought it.
I'm about ready to make the return trip and see what I get.
My return trip from Long Beach to SD (95 miles) today was 23 1/2 mpg. There was more traffic on the way back so I had to slow down a few times and the electric motor took over more than on the way up. Cruise was set at 75 mph. Drive it right and the PB can get good gas mileage, even on the freeway.
