New powerboost mpg

[Tony 70]

Thanks for all the advice, I watched to many YouTube videos.
Going this weekend for a 300 mile trip, and sit back and relax.
And stop checking the mpg every 5 minutes

You’ve gotta run in all electric to see PowerBoost benefits. Running above 55mph, and certainly at 70mph, have no beneficial use of electric and mileage increase. At those speeds, you might as well consider you are running a standard EcoBoost.

I’ve had mine for almost a year and am coming up on 10K and it has gotten better. Dash isn’t accurate to actual. I’ve attached my tracker if you want to see what my journey has looked like so far. As someone mentioned towards, we drive the fourth most powerful truck in the segment behind the lightning, TRX, and Raptor R. It is amazing we get the gas mileage we do! I live in a hilly area in the PNW, also enjoy the throttle a bit, so I doubt I’ll ever see the numbers that some of the members see.

You do have hybrid logic assist while in ICE mode. Depends on engine load and road condition, you can be in EV mode.

No dispute here, but benefit for MPG at highway speeds is just about negligible. Similarly, going into EV mode above 55mph is rare under any conditions outside of downhill with a tailwind. The PowerBoost was designed to reduce poor mpg resulting from starts with loads, and driving in the city, not highway. Just like Lightning owners complaining they can’t get above 1.5 miles per Kw at 75 and 80mph. I’ve had and experienced both.

I average 23 - 29 mpg (highway - city). I accelerate to the speed limit and then get into electric mode as much as possible. I have stock everything and run 35 lbs. in all four tires with a Truxedo X15 Pro.

Of course, strong winds and mountains can change that. I got 19 mpg in the mountains on the way to NC. Then I got 32 mpg from Palm Beach to Key West last year. I park in a garage that doesn't go below 50 degrees in the winter so I can get electric after just a mile or two in the winter with the heater, heated seats, and heated steering wheel on.

I had a lightning and got 1.8-1.9 at 75-80 on the interstate. Unfortunately it got totaled by a teenager pulling out in front of my wife. Everyone was fine though.

Depending upon temperature and other variables, I could get 2.1 or better traveling 80 miles to my Job at 65 to 72mph. Then coming home the “backroads” at 55mph max, 2.4 and greater. My SR killed me. Looking at an extended range now.

You're going to hear a lot of things on this. Some of it even true. Some not 32mpg on the interstate? When hell freezes over. For that matter, tire pressure once over 32-35 psi, is pretty much a non-issue. Rolling resistance to low PSI is non-linear, and darn near insignificant over 35. Mind you heavy payload will require more air.

These things are incredibly touchy re: mpg:
1) They are very aero dependent. More than anything I've owned. A headwind will eat mpg up, and so does speed. BTW, drafting behind a semi will add an easy 1 mpg, and I've seen bigger results towing. Don't to it at night though - The glare pisses semi's off (understandably).
2) Boost kills mpg too. Wind, towing, even hilly terrain - Lock out gears as needed to stay (as a general rule) out of boost. I just drove several hundred miles in 7th (headwind, towing a light open trailer) and pleased to get 15mpg. substantial testing shows higher rpm hurts MPG, but not as bad as boost does. BTW, I'd have gotten >17 with a V-8...
3) The 22's on (as I recall) lost the autolocking front hubs (OWE or similar). We lost 1 mpg on paper, but in practice the 21 guys seem to get more like 2 mpg better.
4) They don't like to be cold. Yea, some is the cats warming up, but it's more than that. Thick wheel bearing grease and etc? The HV battery takes a hit? I dunno, but I know that mine is vastly better once warmed up, and also much much worse in the winter "warmed up" or not. More than just "winter blend fuel" can explain. Bottom line: Warm climate guys always have better results.
5) Chasing results using higher octane means nothing. Yea, it will do a tiny but better, but not enough to offset the cost (or even close. I may yet look at water injection though)
6) Sort of like EV cars, local driving can, in the right circumstances, deliver better results than interstate use. My PB won't run on battery over 42MPH, but below that, on level ground, you can "force" it to use EV enough to make a difference. Interstate is of little to no benefit.
7) I tend not to believe this kind of thing, but I lean towards feeling like my mpg went up when I added a bed cover. Now I'm long-bed and tow mirrors, so a drag mess, meaning I may experience any little improvement more than average.

How you use your's will alter you lifetime average a lot. I suppose I get, in old-man/local mode, an average of 19-20 in the summer. Summer - Interstate, 74mph I can get 20, I could hit 22 drafting. Winter at 78 (real winter, not some california "oh it's cloudy, I need a sweater"), I'm seeing 16-17.

All this w/stock '22 KR PB LWB SCREW + Maxtow.

ymmv.

 

[Tony 70]

Getting around 22 mpg highway and city. Pretty happy with that so far.
My 23 Tacoma averaged 14-16.
Did some driving in the mountains over the weekend. The powerboost was great.
Torque makes a big difference

 

[Radiganp]

Gets about the same mileage as my tuned G70 I’m happy I’d love over 20 average but it gets around 3mpg better than my 19 3.5 got

Two things to add to this:
1) EcoBoost should be called Eco Or Boost; once you get into Boost, the Eco goes away;
2) Having towed keelboats and horse trailers for tens of thousands of miles all over Texas and beyond, I gained an appreciation for the effect that traffic (in addition to wind) has on mpg. On open roads with a trailer, your foot gets tired from how hard you have to press on the pedal. Get into an urban highway, same speed, but with traffic all around you, and you barely have to touch the gas. The wide disparity that you read about in mpg likely has to do with 1) speed of travel, and 2) whether that travel is on open roads or on a busy interstate.

So, instead of disbelieving others' claims of mpg (at least those within reason), consider that your driving conditions may be different.

 

[dafish]

W're probably of at least some agreement. I tow 1,000 miles each outing, so I get traffic, although I don't see much improvement from anything less than semi's. Just a question of how much affect a honda civic can really have on the air around you. And of course I'm talking at interstate speed. Still, I don't tow through large cities/high traffic at speed, so perhaps a large enough mass has some benefit as well.

At the same time statements like "32mpg" sets an unreasonable expectation. That's not happening on any interstate or even highway in any reasonable circumstance. Maybe in a '21, at 40mph with a 25mph tailwind on perfectly flat ground, but that's really not reasonable to be sharing as a baseline for others to experience. And since it does set expectation, I'm OK calling "BS" to that kind of statement.

Of course we need not agree either. Best of luck to you!

I was missing mine today as I was pumping gas. Then I remembered the brutal depreciation on it and why I didn’t get another one right now and then I didn’t miss it ?

 

[Eskram]

I got 10.6 MPG going to get beer today. Admitted, it was less than a mile round trip, and I was in sport mode, TC off, and got sideways for a few seconds.

Last week, I got 27 MPG driving 35 miles or so on the interstate. Crazy how that works. ?‍
