PowerBoost MPG - WTH??

Samson, if you find said thread or related please let me know. Whatever I have now is useless

Didn't you just get a new truck? You need FDRS updates!

Scheduled for Thursday already. i trust few dealers, so I‘m trying to learn the things to say to get to make sure I don’t get some minimal “it’s okay“ rubber stamp.

 

[HammaMan]

Dealer isn't going to FDRS you up-to-date. They'd want to bill $1k to do that. Don't pay them a penny for updates they won't do for free. There's a few mongooses running around here to get you taken care of.

PM me your vin.

Here it is. I’m terrible at providing links and such, but I can screenshot lol. I used the forums’ search function and @Jesse-Infotainment

Picked up my new-to-me '22PB KR in Cleveland yesterday. I'd rented a V-8 4x4 crew cab Ram 1500 from Budget as a one-way rental to get there. For a rental truck I ended up being really impressed. Part of that was the 20MPG average at 77-78mph for the <500 mile trip.

The PowerBoost? 16.7 mpg. Our almost identically built '18 Ecoboost can pretty reliably deliver 18mpg at those speeds. And I mean all but identical. Same bed, both max tow, both 3.5 turbo SCREW's, even same tow mirrors. Heck, same power folding side-boards. Of course the '18 will be 500lbs or so lighter. I suppose I expected too much, but I had hoped powerboost would have added 1-2 MPG on the highway. Fuelly sort of supported that hope, so did reading around the web. Yet the only way this was gonna get 20MPG was off a cliff.

Yes, in 2 wheel high, yes in eco mode. I'd blame the cold weather, or winter fuel, but the Ram 1500 just delivered 20mpg over the same trip. I wasn't towing, and I didn't see it running on boost. Wind not significant, and it did as poorly headed south as it did headed west. No error codes, 41psi in the tires, 27k miles on the truck, so it's broken in. Hybrid mode as least superficially works, for I can drive gently around a parking lot for a couple hundred feet, and watching power delivery mode today I see it occasionally hitting "hybrid mode".

Doing worse than the '18 is a bit of a surprise, doing worse AND having hybrid support to keep it off the turbo on hills and etc was REALLY a surprise. Sure slowing down helps, but the point is the PB just crapped the bed relative to it's peers.

Thoughts? Phone number to a suicide prevention hotline?

Thanks in advance,

You just described the performance of my '22 Powerboost Lariat. It does about 1mpg better than my 2019 3.5 EB in warm weather. In 35,000+ miles of driving I have made 24MPG on exactly one trip; otherwise it runs about 20mpg summer and 18.5 mpg winter. The Powerboost economy seems to vary greatly vehicle to vehicle, where some folks are getting better than advertised but a lot are getting what you and I are experiencing. Sorry, wish I had better news for you.

It’s not uncommon for me to get between 25 and 27 mpg‘s at highway speed (65-75 mph). I have yet to equal that in Eco mode unless I’m driving under 50 miles an hour. Eco mode at highway speed will not give you strong MPG in my experience. I have a 2023 power boost Lariat and still trying to figure out Eco mode to get better max MPG.

I have found the truck shines in city stop and go driving. There is literally no penalty for driving a 5,800 pound, 430hp full sized truck around town. Out on the Interstate its mpg is similar to other lesser trucks. It’s still more powerful if you drop the hammer so there’s that.

Keep in mind, when you first pick up your truck it has done a ton of idling from the factory. So your mpg calculations are way off. Between leaving the factory, then going to the holding lot at the rail yard, then loading and unloading off the rail, then getting to the dealer the truck has basically just sat and idled. You are getting 0 mpg while this occurs. When I first picked my EB it got 11-12mpg on the trip home and I was also worried. My '15 5.0 got almost 19mpg when I traded it in. After 72k miles, my EB averages 18.7. Not bad considering bigger tires than my '15, more power and it is hard to not drive these beasts like you just stole them. Too fun to drive to just limp along!!!

Don’t forget it’s a 3.73 truck with a lot of power as well. The mpg is the same as mpg specd trucks.

This seems to be on point and has quite a few links in the description.

Just to add another data point for you. We took a trip in my Powerboost in October where it was mostly highway with cruise set at 75. I struggled to maintain 20-21 mpg at times. Coming home we took a slightly different route that was mostly done at 70 with a few stretches at 65 and there I was getting 22-23 at 70 and 23-24 at 65. I believe it was here, but someone plotted a chart of how their mpg tanked as speeds increased.

Also, the battery does assist on the highway when going up inclines to avoid boost. You won't see full electric at highway speeds unless you force it or you have a long downhill stretch and it shuts off the engine to regen brake better. The battery assist won't count for anything significant if all you have is highway miles.

I have found that I can squeeze even more miles out of a gallon without cruise control.

 

[dafish]

i believe that as well.

I prefer to maintain a constant speed and lock out gears as needed to optimize fuel economy rather than being someone that is going 80 just because I'm going downhill or 50 uphill. In the long run, your savings are likely minimal, and you'd probably be better off just setting cruise at the speed limit of fuel economy is really that big of a concern.
